Drink Water!

When we think about nourishing our bodies, most of us fixate on the foods we eat. Which diet should I follow? Which will give me the right balance of protein, carbohydrates, and fat? Should I take supplements and, if so, which ones? Amidst all this musing, we give little thought to an incredibly important element of our daily intake: WATER.

As adults, we are all roughly 50-70% water by weight. Water is the primary component of all body parts and plays a major role in numerous life-sustaining functions. According to the “rule of threes,” we can survive only 3 minutes without breathable air, 3 days without drinkable water, and 3 weeks without food.

So, what does water do for us?

glass of waterWater produces saliva that begins the breakdown of foods in our mouths. Drinking water before, during, and after a meal supports healthy digestion. It also gives the stomach a means to register fullness, thereby moderating the impulse to overeat.

Water helps dissolve vitamins, minerals, and other nutrients from our food. It uses the bloodstream to transport these nutrients to every cell in our bodies. It keeps our cell membranes moist and provides the means for them to grow, reproduce, and thrive. It also helps our skin look its best.

Water helps excrete waste from our systems through sweat, urination, and bowel movements. Appropriate water intake is protective against urinary tract infections, kidney stones, and hemorrhoids. And when we consume the recommended daily dose of fiber to feed our good gut bacteria, adequate water ensures that all this roughage doesn’t turn to “concrete” on its way out of our systems!

Water lubricates our joints and cushions sensitive tissues in our spinal cords and brains. It’s the body’s built-in shock absorber. The brain also uses water to manufacture hormones and neurotransmitters.

Water regulates our internal body temperature through sweat and respiration. And since breath is naturally humidified, we expel water even when our bodies chug along at the optimal temperature.

How much water do we need?

The U.S. National Academies of Sciences, Engineering, and Medicine deems an adequate daily fluid intake to be 15.5 cups for men and 11.5 cups for women. These recommendations account for water from all sources – water, other beverages, and food. As such, the “rule of thumb” of consuming eight 8-ounce glasses of water per day should generally do the trick.

Water intake needs to increase if living in a hot, humid climate or exercising strenuously to account for the body’s water loss via sweat to lower body temperature. Airplane travel can lead to dehydration due to the dry cabin air. You also need to drink more water if feverish or subject to fluid loss through vomit or diarrhea.

Note: For each pound of body weight lost in exercise, you need to rehydrate with 16-24 ounces of fluid. A high quality sports drink helps replenish fluid and electrolytes while providing a source of calories for fuel.

How do I know if I’m getting the right amount of water?

Check out the color of your urine first thing in the morning. If you are adequately hydrated, it will look like pale lemonade. If there’s very little discharge or it looks like apple juice, it’s time to pour yourself a tall glass of water! Other signs of dehydration include unexpected weight loss, confusion, dry skin that’s hot to the touch, and elevated core body temperature.

Note: There’s a lag time between the onset of dehydration and thirst. If you are thirsty, you are already running low on fluids.

Is it possible to drink too much fluid?

The gastrointestinal track can only handle 1-2 liters of water at a time. Flood your system with fluids and your kidneys can’t keep up with the deluge. The resulting overhydration dilutes sodium in the blood – a condition called hyponatremia – which could lead to a life-threatening medical emergency, such as cerebral edema.

Renewed Focus on Nutrition

For me, the start of a new year always tees up the opportunity to launch self-improvement initiatives. Diet and nutrition head this year’s list. Though I’ve read and have written quite a bit about the subject, there’s always more to learn. My guide for the next several posts will be Dr. Roberta H. Anding, Assistant Professor at the Baylor College of Medicine and a clinical dietician with over 30 years’ experience. She teaches an outstanding course entitled Nutrition Made Clear on Great Courses Plus.

What is this topic so important?

As a nation, we’re becoming increasingly unhealthy. According to the Centers for Disease Control, the majority of Americans are either overweight (i.e., their Body Mass Index or BMI ranges between 25 and 3) or obese (i.e., their BMI exceeds 30)… and the trend data are not heading in a favorable direction.

us trend data on body mass index

Excess body fat has been linked to elevated risk for heart disease, stroke, type 2 diabetes, certain types of cancer, osteoarthritis, sleep apnea, and clinical depression. Beyond the deleterious effects on the individual, these conditions result in staggeringly high medical costs.

So how did we get here?

The simple answer: We eat too much food and too much of the wrong kinds of foods.

average daily per capita calories

We’ve gotten the message. According to Pew Research, 54% of us believe that we’re paying closer attention to healthy eating that we did 20 years ago; however, 58% of us think we should eat healthier most days. Mintel’s research tells us why:

  • 43% of Americans believe that it’s difficult to be healthy given our modern lifestyle
  • 80% believe healthy living demands sacrifice
  • 40% find the health information landscape confusing

That last point bears closer examination. There is SO MUCH information about diet and nutrition out there. BusinessWire reports that the U.S. weight loss market is now worth $72 billion. That’s a whole lot of financial incentive to promulgate dietary information that may or may not reflect hard science. Dr. Anding raises warning flags for:

  • Promises of quick and effective cure-alls
  • Claims miraculous breakthroughs, secret formulas, and treatments
  • Bamboozling medical terminology
  • Attempts to equate “all natural” with safety and efficacy
  • Aggressive use of personal testimonials
  • An artifice of scarcity – e.g., “limited supply,” “act now”
  • Money-back guarantees

In short, if it’s too good to be true, it probably isn’t true.

There’s no substitute for going back to basics – i.e., eating a balanced diet of whole, unprocessed foods in the right amounts consistently. While it takes a bit more investment in time, I’ve learned to multi-task while preparing meals – e.g., watching TV while doing food prep, or listening to an audiobook or podcast while cooking. I’ve found ways to make healthy meals taste really good. (Just ask my husband!) And I watch portion size.

If you’d like high quality information, Dr. Anding recommends the following resources:

To that list, I would add www.NutritionFacts.org. I’ve been watching Dr. Michael Greger’s short videos for years and consistently find them well-constructed, newsworthy, and evidence-based.

The Trouble with Beef

cattle

Climate change has emerged as a “hot topic” in recent Presidential elections. Green-leaning candidates leverage the increased frequency and severity of weather incidents as proof sources that our planet is becoming increasingly less healthy. Most promote “clean energy” and call for reduced emissions from motor vehicles. According to the National Center for Biotechnology Information (NCBI), they should also promote increased consumption of plant-based foods to reduce our impact on the environment.

The NCBI sounded alarm bells on the global livestock industry years ago. Here are some troublesome facts as presented in a report entitled Reducing the Environmental Impact of Dietary Choice:

  • Our global community uses 30% of its land to raise livestock. Deforestation to support animal habitats reduces biodiversity (on which human life depends) and negatively impacts freshwater supplies by increasing runoff.
  • We use 70% of our global agricultural land to produce livestock feed – typically corn, soybean meal, and grains. These crops consume millions of pounds of pesticide and billions of pounds of fertilizer.
  • It takes 11 times more fossil fuel and 100 times more water to produce protein from meat than an equivalent amount of vegetable-based protein.
  • Livestock accounts for 18% of total greenhouse emissions which include nitrous oxide, methane, carbon dioxide, and ammonia.
  • Livestock consume 8% of freshwater directly and thwart groundwater replenishment through soil compaction and degradation to the banks of waterways.
  • A vegan diet was determined to have the lowest environmental impact.

The Environmental Working Group’ report entitled Meat Eater’s Guide to Climate Change and Health doubled down on the environmental perils of meat consumption:

  • Lamb, beef, and cheese production generates the highest emissions. (Since beef produces milk and cheese, we need to cut back on those products as well as steaks, ribs, ground beef, et al.)
  • Beef generates more than twice the emissions of pork, nearly four times that of chicken, and more than 13 times that of vegetable proteins such as beans, lentils, and tofu.
  • In the U.S. alone, livestock generated three times the amount of manure (waste) as humans. While in theory it could be used as fertilizer, in practice it tends to simply pile up and pollute.
  • As of 2009, confined feeding operations have been responsible for damaging water supplies associated with 34,000 miles of rivers and 216,000 acres of lakes and reservoirs. (No doubt today’s figures would be even more eye-popping!)
  • Slaughterhouses dump vast quantities of pollutants into our waterways which contaminate our drinking water, kill fish, and create “dead zones.”
  • Widespread use of antibiotics on livestock promotes the development of resistant strains that threaten human life. Antibiotics prove necessary to minimize disease in overcrowded spaces. (As a side benefit, they promote growth, thereby improving profit margins.)
  • If everyone in the United States ate no cheese or meat once a week over the course of a year, it would have the equivalent impact of taking 7.6 million cars off the road.

Even though these findings call for us to reduce meat eating drastically, our dietary patterns are moving in the opposite direction. The NCBI reports that worldwide meat consumption tripled between 1971 and 2010 during which our population grew by only eighty-one percent.

If we take environmental scientists at their word, we cannot sustain our current eating habits. They exacerbate global warming, needlessly contribute to the degradation of the environment, and deplete nonrenewable resources. Given the eminent threat of food and water shortages, it makes no sense to stay this course.

When it costs so little, why not take the plunge and shift some or all the daily menu to more environmentally sensitive choices?

The Trouble with Chicken

chickens

Chicken used to play a big role in our meal planning. We regularly ate eggs for breakfast, opted for chicken atop our lunchtime salads, and featured chicken most nights for dinner. When I started reading up on diet and nutrition a few years ago, we made the switch to a predominantly whole food plant based diet. So, chicken has fallen out of favor in our household. As it turns out, chicken has also fallen out of favor with epidemiologists and environmentalists, too.

According to the Pew Environmental Group,1 chicken is the most popular meat in America. In the forty years between 1970 and 2010, we doubled our per capita chicken consumption (to 84 pounds annually) while expanding the US population by ~50%. The poultry industry responded by gearing up production and finding ways to bring their products to market at lower cost for producers and consumers. Their key strategy: economies of scale.

Sentience Institute’s US factory farming estimates suggest that we raise 99% of our meat chickens and 98% of our egg-laying chickens in concentrated animal feeding operations (CAFOs).2 For chickens, the USDA defines a CAFO as an operation in which 125,000 meat chickens or 82,000 eggs chickens are confined for over 45 days per year. Breeding and specialized feed have enabled chickens to reach their full weight in just 6-7 weeks.

Conditions within factory farms are rather grim. There’s no fresh air or natural sunlight. The animals live beak-to-beak atop their droppings, breathing the ammonia fumes from all their waste. Overcrowding brings on stress which dampens their immune systems and elevates aggressive behavior. (My first case study in business school examined the practically of fitting chickens with blurry contact lenses so they’d be less successful in their attacks on other birds.) A lack of exercise and excess weight puts strain on their muscular-skeletal systems which may give rise to suffering.

If your compassion for chicken life has not been aroused, perhaps your concern for human life might be. According to Dr. Michael Greger,3 these environments are breeding grounds for the frightening emergence of supervirus strains. Hundreds of individuals were infected by the Avian influenza (H5N1) in 1997 for which there was a 50% fatality rate. The 2002 SARS-CoV outbreak claimed 774 victims among 8098 cases, or a 9.5% fatality rate. The 2012 MERS-CoV outbreak claimed 858 deaths among 2499 laboratory-confirmed cases, or a 34.3% fatality rate. These outbreaks were subject to rapid containment because the afflicted parties presented clear manifestations of illness. We have not been so fortunate with COVID-19. Though its fatality rate is far lower than other CoV strains to date, its ease of transmission and prevalence of asymptomatic carriers presents substantial hurdles for containment.

Dr. Greger warns that the worst may be yet to come. An H7N9 virus has managed to jump from poultry to humans, killing 616 of the 1568 infected. While it hasn’t yet acquired the capacity to transmit from human to human, animal factories may present an opportunity for mutation that would activate a human type receptor. If so, the results could be devastating in loss of lives, disruption to supply chains that support life, and massive economic losses.

Even if we were to turn a blind eye to our exposure to deadly viral agents, we should acknowledge the environmental risks posed by CAFOs. Pew Environmental Group tells us that these operations produce an enormous amount of waste that cannot be used productively for cropland nutrients. The excess washes off the land and into local streams, rivers, and other bodies of water. The resultant algae overgrowth creates a hostile environment for fish and other marine life, often creating “dead zones.”

While advocacy groups and regulators are busy figuring out how to adjust factory farming standards to mitigate risk to human and environmental health, there are two simple practices that we can adopt to reverse these unsettling trends:

  • Reduce the demand for poultry by reducing the amount that we consume. (I rarely eat chicken or turkey these days and don’t miss it at all.)
  • Purchase free-range poultry from farmers who raise their animals humanely and safely. (You can generally find these folks at local farmers’ markets.)

Whole Food Plant Based Diet Boosts Immune Function

covid-19This week’s reporting on COVID-19 tells us that over 1.5 million US residents have tested positive for the disease and over 90,000 have been confirmed to have died from it. Such figures fail to count those who have not presented symptoms sufficient to warrant testing nor those whose deaths fell outside the net of COVID-19 tracking. The elderly and those who are immunocompromised represent a disproportionate percent of deaths. And there is no end in sight.

As a member of a household with above-average risk of severe infection, I’m paying close attention to actions we can take to help our bodies prepare for the “fight of their lives” should it come to it. A prime focus centers on our diet. Here’s why…

Scientists tell us that the COVID-19 virus enters the body principally through the nose and mouth; it uses lung tissue as its initial breeding ground. So, the first line of defense against the invader must be the mucosal membranes of the oral cavity and respiratory tracts. These membranes fight infection by secreting Type A antibodies (called secretary immunoglobulin A or SIgA). According to a study published by the University of Western Sydney, we can boost our SIgA response by consuming mushrooms. Healthy volunteers who added one cup of mushrooms to their daily diet showed 50% more Type A antibody secretion than the control group. [See Note 1.]

Should a virus break through mucosal membrane fortification, the body’s innate and adaptive immune responses go into action. Our innate immune response avails itself of natural killer cells that target pathogens, including viruses responsible for common respiratory infections. The adaptive immune response designs and produces antibodies that are custom-tailored to combat specific invaders. For proper functioning, the adaptive response must be sufficiently nimble to ramp up production during the window of opportunity in which the infection can be contained without going on overdrive and recklessly attacking its own vital tissues.

I used to think that the immune system was something that was genetically pre-determined. You either had a good one, or you didn’t. But it turns out that its functioning has a great deal to do with the quality of the microbiome in our intestinal tract. As discussed in a prior post, the microbiome plays an active role in digestion, vitamin and amino acid production, and metabolic regulation. With advancing technology, scientists can now trace the extent to which the microbiota and immune system work symbiotically to provide for the body’s response to microbial threat and maintenance of overall health. [See Note 2.] In short, a well-functioning microbiome provides the means for favorable gene expression and serves a crucial role in immune homeostasis. To that end, we must pay close attention to what we eat.

vegan dietHere are a handful of evidence-based recommendations:

Eat 5-7 servings of fruits and vegetables daily. While immune function tends to decline in older adults, one study considered the possibility that older adults are simply getting too few servings of fruits and vegetables daily. It traced the efficacy of vaccine-induced antibody response in two groups of older adults: one ate 5 or more servings of fruits and vegetables daily, and the other only 2. The former demonstrated a 2.5x boost in immune response versus the latter. [See Note 3.] Word to the wise: Eat a colorful assortment of produce to maximize phytonutrient diversity and make your meals interesting.

Make sure your diet includes plenty of fiber. Undigested complex carbohydrates elevate production of short-chain fatty acids (SCFAs) that serve as energy sources for the gut microbiota and intestinal epithelial cells. Epithelial cells serve as gatekeepers that permit absorption of healthy substances into the body and block entrance to harmful ones. To that end, load up on whole grains, legumes, fruits, and vegetables.

Add immune-boosting superstars to your diet, notably mushrooms, bitter greens, garlic, green tea, and kiwifruit.

Add a tablespoon of ground flax seeds to your daily regimen. They’re loaded with anti-inflammatory omega-3 fatty acids and aid in the absorption of fat-soluble vitamins like A, D and E, all of which are crucial for immune health.

Avoid highly processed and fried foods as they increase inflammation, deplete nutrients, and dampen immune response.

Finally, a study published through the CUNY School of Public Health explored the health advantages of a strict vegan diet over vegetarian or healthy omnivore alternatives. [See Note 4.] It found that the vegan microbiota showed reduced levels of resident microbes with pathogenic potential and a greater abundance of protective species. The vegan microbiota was also associated with reduced inflammation and lowered the risk of arteriosclerosis.

How I Learned to Love Cooking

In my last post, I talked about our recent decision to buy a share in Community Supported Agriculture. It’s something we’ve been wanting to do, and it’s a good year to do it. But, of course, when you get all that fresh produce, you’ve got to figure out something to do with it!

i love cooking

I wasn’t born a cook and was never much interested in it. I took up the mantle as a teenager to help my parents. They both worked full time, so I pitched in and got dinner on the table as they returned home from their days’ labors. But it was all pretty mundane stuff, and Mom did all the grocery shopping and planning.

My cooking and eating habits stayed pretty basic throughout college and grad school, and I became a frozen dinner, fast food, and dining out aficionado during my working years. I was really, really busy and didn’t want to spend much time in the kitchen. Now and again I’d build up a head of steam and prepare something amazing. But the day-to-day grind of meal preparation just didn’t interest me.

In summer 2015, I read Chris Guillebeau’s book entitled The Happiness of Pursuit: Finding the Quest That Will Bring Purpose To Your Life. In it, he reflects on his 10-year quest to visit every country in the world and encourages readers to identify adventures that will enrich their lives and satisfy inner longings. I took his advice and opted to prepare every recipe in the most challenging cookbook on my bookshelf.

In truth, I didn’t have inner longings around cooking. But I’d just seen the movie Julie & Julia and figured this quest would be something that I could manage on top of all my other responsibilities.

I’m proof positive that gourmet cooking takes a LOT of time in the kitchen. Mercifully, Spike provided able assistance and saved my proverbial bacon on numerous occasions. (Of course, he had a vested interest in food getting on the table!) But it turned out to be a lovely way to spend our evenings together. We spent more time talking and less time vegging out in the front of the TV.

I learned that cooking from scratch was far more flavorful than cooking with short-cuts. There is a material difference in taste between fresh herbs and dried herbs and between bottled garlic and fresh garlic – well worth the incremental food preparation time. Moreover, those complex recipes turned out to be mouth-wateringly flavorful, and it wasn’t as hard to prepare them as I feared they might be.

The quest has introduced Spike and me to several new ingredients – e.g., celery root, chanterelle mushrooms, spaghetti squash, calvados, gruyère cheese, to name a few. By stretching our boundaries, we became much more familiar with the inventory at our local grocers and in the farmer’s market. I’m awestruck by the bounty of food that we enjoy in the Pacific Northwest!

We realized early on that the quest would go slowly if we had to eat all of the food that we prepared. So, we started inviting people to dine with us, given fair warning that they’d be noshing on food we’d never made. Suffice it to say, the fellowship was even better than the food, and the food was really good. In the process, I’ve gotten over my fear of being a sub-par hostess. No one judges me. They’re just happy to eat, drink, and be merry!

I’ve learned to suspend my tendencies toward perfectionism and beating myself up when things don’t go well. We had a few mishaps in the kitchen, and we sampled a few recipes that didn’t send us over the moon. Oh well! No big deal! I have confidence in my ability to improve on my technique and the discernment to know when it’s not worth the effort.

I’ve since worked my way through 8 other cookbooks and am closing in on 1,400 total new recipes sampled. Being a “test kitchen” takes the drudgery out of meal preparation and helps turn ordinary evenings into date nights. Spike still helps me in the kitchen, and we still enjoy a good chat while we’re cooking.

I’ll look forward to the day when our social distancing restrictions get lifted, and we can have friends over for dinner again!

Community Supported Agriculture

As noted in an earlier post, my husband and I are dedicated locavores who regularly patronize the Beaverton Farmer’s Market. I love milling around the fruit and vegetable stands, and it is great fun to interact casually with all the other locals who share our enthusiasm.

Our favorite weekly pastime has been disrupted by the coronavirus pandemic. The usual crowds will not allow for a safe distance to prevent viral transmission. We don’t want to roll the dice and hope that we’ll avoid infection or weather it successfully should we succumb. Since we’re still committed to supporting local farmers, our next best strategy is to buy a share in Community Supported Agriculture (CSA).

community supported agriculture

Farmers create CSAs to establish patronage for their wares. In return for advance payment for a season’s worth of produce, they provide a weekly allotment of fruits, vegetables, flowers, or other items at designated pick-up locations. This arrangement helps them manage their cash flow and handle marketing efforts before spending really long days in the field. Their shareholders get ultra-fresh, ultra-healthy, chemical-free food along with exposure to new vegetables and new ways of cooking. They also develop relationships with the farmers who grow their food.

In the best of all worlds, farmers receive a great income for their labors, and shareholders reap the bounty of a delicious harvest for however long the season lasts. Should nature conspire against the farmers and yields run lower than anticipated, shareholders agree explicitly to get a little less value for their dollars. That’s where the “support” comes into community supported agriculture. It’s a commitment to support local farmers in plenty and in want. I think it’s a fair and reasonable deal. They put themselves on the line every year to provide for our bodily nourishment. It’s only right that we put our dollars on the line to provide for their financial security.

Whether you are a patron of a farmer’s market or a CSA shareholder, you are in partnership with Mother Earth and the future generations that she’ll support. By purchasing organically grown, locally produced fruits and vegetables, you’ll contribute to:

Attentive care of the soil on which life depends: According to a Cornell University study, it takes 20 years for less than a millimeter of soil to replenish itself naturally. Organic farmers help Mother Nature along by ensuring that they do not needlessly deplete the soils’ nutrients and by planting nutrient-rich cover crops to replenish this living organism. Cover crops also protect the land from top soil run-off. According to the United Nations, poor soil management globally accounts for loss of a third of the world’s arable land and could reach a point of crisis within the next few decades.

Protection of our groundwater and marine habitats: According to the US Geological Survey, roughly 25 metric tons of nitrogen, phosphate, and potassium flood U.S. soils annually to boost yields. The excess leaches into the soil and contaminates our groundwater. Moreover, the runoff contributes to algae blooms in our major waterways, oceans, and the Gulf of Mexico which disrupt our marine ecosystems.

Reduction in use of pesticides and herbicides: According to the NIH National Library of Medicine, the U.S. consumes ~1 billion tons of pesticide annually, and in 2014 alone, farmers sprayed enough glyphosate to apply 0.8 pounds per acre of cultivated cropland. While these products boost yields, they carry a hidden cost in the integrity of our natural resources and our health.

Reduction in CO2 emissions and their attendant impact on global warming: Food travels within 50-100 miles of your table, not hundreds of miles by plane, train, or automobile.

Tens of thousands of families have joined CSAs over the past few decades. In fact, they’re so popular in the Pacific Northwest that I had a difficult time finding a farmer who had available shares for purchase. Suffice it to say, I’m glad that I finally got off the dime and signed up for a June through October season. It does the planet, the farmer, and my household good!

Harvard Weighs in on Nutrition

I just finished reading an article1 about Dr. Frank Hu, professor of nutrition and epidemiology at the Harvard T.H. Chan School of Public Health. He and his colleagues created the following Healthy Eating Plate based on the best available scientific evidence:

healthy eating plate

Vegetables: Eat lots of them – the greater the variety the better. Potatoes, French fries, and tater tots don’t count.

Fruits: Eat plenty of fruits of all colors.

Whole Grains: Eat a variety of whole grains; limit refined grains (e.g., white rice, white bread).

Healthy Protein: Choose fish, poultry, beans, and nuts; limit red meat and cheese. Avoid bacon, cold cuts, and processed meats.

Water: Drink water, tea, of coffee with little to no sugar. Limit milk/dairy and juice. Avoid sugary drinks.

Healthy Oils: Use modest amounts of olive oil or canola oil for cooking and in salads, as needed. Limit butter. Avoid trans fats.

Unlike the U.S. Government’s Eating Plat, the Harvard version does not have a specific provision for dairy, and it places far greater emphasis on vegetables.

Dr. Hu and his colleagues are as concerned about our health as they are the health of the planet (which are, of course, inexorably intertwined). According to the article, food production accounts for 80% of deforestation, 70% of fresh water use, and 30% of human-generated greenhouse gas (GHG) emissions. Meat and dairy production account for 80% of the food industry’s GHG. Moreover, it takes 11 times more fossil fuels to produce a single unit of animal protein than it takes to produce a comparable amount of grain-based protein.

If eating meat were deemed healthy, there’d be a painful trade-off between bolstering human health and bearing the environmental cost. But it turns out that meat isn’t that healthy. Findings from the 2012 Health Professionals Follow-Up Study and Nurses’ Health Study revealed that increasing one’s consumption of meat by a single serving per day elevates morbidity risk by 13-20%.

Hu has published several papers on plant-based diets but claims that it does not have to be vegan or vegetarian. As I’ve read elsewhere, meat as a condiment instead of prominent occupant of the plate seems to be alright (though processed meats are not good!)

Hu and his colleagues face an uphill battle in gaining governmental traction on their recommendations. Powerful political and commercial interests stand in their way. And, to be sure, there are still randomized, double-blind studies to be done to solidify their research. But as Hu says: “Globally, if we always just wait for the absolute proof or conclusive evidence, then it’s going to be disastrous. It’s going to be too late for both human health and the environment.”

Daily “Tricks” to Support Weight Loss

hints and tipsIn my final post on Dr. Michael Greger’s How Not to Diet: The Groundbreaking Science of Healthy, Permanent Weight Loss, I’ll cover the a few “tweaks” that he recommends to optimize a diet for weight loss. (He advises a consult with your doctor if you have any medical conditions or have difficulty with any of these recommendations.)

At Each Meal:

  1. Drink 1-2 glasses of cool or cold water before eating.
  2. Start each meal with “negative calorie” foods – e.g., an apple or a very light soup of salad
  3. Flavor meals (or a glass of water) with 2 teaspoons vinegar.
  4. Focus on eating, not the TV, notepad, or smartphone.
  5. Decrease bite size and eat slowly to allow for the 20 minutes necessary for your brain to catch up with your stomach.

Every day:

  1. Take in 1/4 teaspoon black cumin powder.
  2. Use 1/4 teaspoon garlic powder.
  3. Use 1 teaspoon ground ginger or 1/2 teaspoon cayenne pepper.
  4. Eat 2 tablespoons nutritional yeast. (When pre-packaged, it’s usually near the spice section. Otherwise, check out the bulk foods section.)
  5. Take 1/2 teaspoon cumin with lunch and dinner.
  6. Drink water, black coffee, or hibiscus tea during meals. Drink 3 cups of green tea daily between meals, waiting at least an hour after you finish eating.
  7. Drink a glass of water hourly, fitting in at least 8 cups throughout the day.
  8. Eat whole (intact) grains to make your microbiome happy. Flour doesn’t count.
  9. Have your largest meals earlier in the day. Eat breakfast like a king, lunch like a prince, and dinner like a pauper.
  10. Confine your meals to a 12 hour window – e.g., 7:00am to 7:00pm.
  11. Exercise 90 minutes daily. (For optimal results, wait 6 hours after your last meal – e.g., first thing in the morning.)
  12. Weigh yourself regularly.
  13. Work on establishing good habits (and breaking old ones) with a set of intentions – e.g., when I sit down to watch TV, I’ll drink a glass of water and work on a Sudoku puzzle to break the habit of snacking mindlessly. Take stock daily on how you’re doing. Adjust your list every 2 months.

Every night:

  1. Fast after 7:00pm.
  2. Get a good night’s sleep!

If any of these recommendations seems peculiar, I have a suggestion for you. Get a copy of Dr. Greger’s book and read it cover to cover! As I’d mentioned in the introductory post to this series, he provides nearly 5,000 citations of credible (vetted) scientific evidence for each one of his recommendations. And by investing the time to read this amazing book, it’ll hep you reinforce your commitment to a healthier you!

Weight Loss Boosters

In my third installment of findings from Dr. Michael Greger’s How Not To Diet: The Groundbreaking Science of Healthy, Permanent Weight Loss, I’ll briefly summarize his weight loss boosters to help win the battle of the bulge.

diet boostersAccountability: Group therapy, health coaches, and social support produce better results than going it alone. At a bare minimum, weigh yourself regularly to stay focused on your weight loss goals.

Amping AMPK: An AMP-activated protein kinase causes the body to switch from storing to burning fat. It also stimulates production of mitochondria, the energy engines inside our cells. Eat nightshade vegetables (bell peppers, eggplant, tomatoes), barberries, and up to 2 tablespoons vinegar daily.

Appetite Suppression: Ground flaxseed, cumin, and black cumin naturally tamp down our appetites.

Chronobiology: Take advantage of our body’s circadian rhythms by eating when we’re most likely to process food efficiently. The rule of thumb is: Eat breakfast like a king, lunch like a prince, and dinner like a pauper. And don’t snack at night!

Eating Rate: It takes ~20 minutes after we start eating for the brain to put the brakes on our appetites. Eat slowly. Opt for solid foods that require chewing. Even the sensations in the mouth can translate into the sensation of physical fullness. Ergo, nibble and savor rather than chomp and gulp!

Exercise Tweaks: As noted in a prior post, adjusting one’s diet is a far more effective strategy for weight loss than relying on exercise (although exercise confers many other benefits). Choose activities that you genuinely enjoy so that you will be less tempted to reward yourself with culinary treats for doing it.

Fat Blockers: Thylakoids in greens delay fat absorption and decrease ghrelin, the hunger hormone. Superstars include kale, collards, and arugula.

Habit Formation: Build healthy habits so that good food choices (not bad ones!) become automatic. Be intentional every time you put food in your mouth. Don’t eat on autopilot.

Hydration: Substitute water for sugary beverages. Drink filtered water to avoid impurities.

Inflammation Quenchers: Adopt a whole food plant-based diet to maximize anti-inflammatory food substances. Try goji berries (wolf berries); they have four times the antioxidants as other dried fruits. Add turmeric and nutritional yeast to your diet.

Intermittent Fasting: Front-end load calories every day; “fast” every evening after an early dinner. This practice has been associated with lower inflammation, better blood sugar, and improved weight maintenance.

Meal Frequency: The more frequently people eat, the more weight they tend to gain. Break the snacking habit and/or make it really inconvenient to do so.

Metabolic Boosters: Drinking 2 cups of (plain) water boosts the metabolism; doing so four times daily can wipe out 100 calories! Cold water takes more energy to process than warm water. Limit consumption to no more than 3 cups per hour to avoid overload on the liver.

Mild Trendelenburg: Drinking extra water also causes our blood capacity to expand which induces the heart to release atrial natriuretic factor (ATF), a fat burning hormone.

Negative Calorie Preloading: If you drink 2 cups of water or 1 cup of water-rich vegetables before a meal, you tend to eat less during the meal. Apples and grapefruits can produce the same effect, but other fruits did not pass muster. (The sweetness may be an appetite stimulant.)

Sleep Enhancement: When we sleep too little, we tend to crave unhealthy foods and gain weight. Excess weight can be a deterrent to a good night’s sleep due to indigestion, sleep apnea, or physical discomfort. Aim for 7 hours per night of sleep.

Stress Hormone Relief: Much like sleep deprivation, stress is associated with weight gain. (They don’t call it “comfort food” for nothing!) Stress-induced weight gain tends to lodge in the belly – the worst place for it! Remedies include exercise, laughter, yoga, massage, and mindfulness-based stress relief (MBSR).

Wall Off Your Calories: When eating whole foods and whole grains, calories get trapped in their cell walls. It passes through our elimination channel and never makes it inside us. So, that’s an easy way to limit caloric intake. So, for example, choose raw, unprocessed almonds instead of almond butter, or whole grains instead of a slice of whole wheat bread!
