I have no argument with people who adopt a vegetarian or vegan diet for health, religious, environmental or ethical reasons. But I object vehemently to proselytizers who distort science or the support for dietary advice offered to the more than 90 percent of us who choose to consume animal foods, including poultry and red meat, in reasonable amounts.I have no argument with people who adopt a vegetarian or vegan diet for health, religious, environmental or ethical reasons.

Such is the case with a recently released Netflix documentary called “What the Health” that several well-meaning, health-conscious young friends have urged me to watch. And I did try, until I became so infuriated by misstatements – like eating an egg a day is as bad as smoking five cigarettes, or that a daily serving of processed meat raises the risk of diabetes 51 percent — that I had to quit for the sake of my health. While the film may have laudable goals, getting the science wrong simply confuses the issues and infuriates those who might otherwise be supportive.Such is the case with a recently released Netflix documentary called “What the Health” that several well-meaning, health-conscious young friends have urged me to watch.

Please understand: I do not endorse inhumane treatment of farm animals or wanton pollution of the environment with animal wastes and misused antibiotics and pesticides. Agricultural research has long shown better ways to assure the nation of an adequate food supply if only regulators would force commercial operations to adopt them.Please understand: I do not endorse inhumane treatment of farm animals or wanton pollution of the environment with animal wastes and misused antibiotics and pesticides.

Nor do I endorse careless adoption of vegetarian or vegan diets for their name’s sake. A vegan who consumes no animal products can be just as unhealthy living on inappropriately selected plant foods as an omnivore who dines heavily on burgers and chicken nuggets. A vegan diet laden with refined grains like white rice and bread; juices and sweetened drinks; cookies, chips and crackers; and dairy-free ice cream is hardly a healthful way to eat.Nor do I endorse careless adoption of vegetarian or vegan diets for their name’s sake.

Current dietary guidelines from responsible, well-informed sources already recommend that, for health’s sake, we should all adopt a plant-based diet rich in foods that originate in the ground. These can be “fleshed out” with low-fat protein sources from animals or combinations of beans and grains. However, here too, careless food and beverage selections can result in an unhealthful plant-based diet.Current dietary guidelines from responsible, well-informed sources already recommend that, for health’s sake, we should all adopt a plant-based diet rich in foods that originate in the ground.

A very large study recently published in the Journal of the American College of Cardiology is a case in point. The study, by a team from Harvard’s T.H. Chan School of Public Health, examined the relationship between plant-based diets of varying quality and the risk of developing coronary heart disease among more than 200,000 health professionals. The participants, who started the study free of chronic disease, were followed for more than two decades, submitting their dietary patterns to the researchers every two years.A very large study recently published in the Journal of the American College of Cardiology is a case in point.

Based on their responses on food-frequency questionnaires, the participants’ diets were characterized by the team as an overall plant-based diet that emphasized plant foods over animal foods; a healthful plant-based diet emphasizing healthful plant foods; or an unhealthful plant-based diet. Any of the diets could have included various amounts of animal products.Based on their responses on food-frequency questionnaires, the participants’ diets were characterized by the team as an overall plant-based diet that emphasized plant foods over animal foods; a healthful plant-based diet emphasizing healthful plant foods; or an unhealthful plant-based diet. Any of the diets could have included various amounts of animal products.
Healthful plant foods like whole grains, fruits and vegetables, nuts and legumes, as well as vegetable oils, coffee and tea, received a positive score, while less-healthful plant foods like juices, sweetened beverages, refined grains, potatoes and fries, and sweets along with animal foods were assigned a negative rating.Healthful plant foods like whole grains, fruits and vegetables, nuts and legumes, as well as vegetable oils, coffee and tea, received a positive score, while less-healthful plant foods like juices, sweetened beverages, refined grains, potatoes and fries, and sweets along with animal foods were assigned a negative rating.
The more closely the participants adhered to a healthful plant-based diet, the less likely they were to develop heart disease in the course of the study. Those with the least healthful plant-based diet were, on average, 32 percent more likely to be given diagnoses of heart disease. In a prior study, the researchers found a similar reduction in the risk of Type 2 diabetes of a healthful plant-based diet.The more closely the participants adhered to a healthful plant-based diet, the less likely they were to develop heart disease in the course of the study.

The team, led by Ambika Satija of Harvard’s Department of Nutrition, concluded that “not all plant foods are necessarily beneficial for health.”The team, led by Ambika Satija of Harvard’s Department of Nutrition, concluded that “not all plant foods are necessarily beneficial for health.”
Interestingly, the Harvard finding was nearly identical to one from an 11-year European study that found a 32 percent lower risk of coronary heart disease among vegetarians than among nonvegetarians, although no health-based rating was given to the quality of the participants’ vegetarian diets.Interestingly, the Harvard finding was nearly identical to one from an 11-year European study that found a 32 percent lower risk of coronary heart disease among vegetarians than among nonvegetarians, although no health-based rating was given to the quality of the participants’ vegetarian diets.
The more detailed Harvard study, which examined gradations of adherence to a plant-based diet, found that “even a slightly lower intake of animal foods combined with a higher intake of healthy plant foods” was associated with a lower risk of developing heart disease.The more detailed Harvard study, which examined gradations of adherence to a plant-based diet, found that “even a slightly lower intake of animal foods combined with a higher intake of healthy plant foods” was associated with a lower risk of developing heart disease.
In other words, you don’t have to become a strict vegetarian to protect your heart. Simply reducing your dependence on animal foods, and especially avoiding those high in fat, is helpful. In fact, “a diet that emphasized both healthy plant and healthy animal foods” was associated with a coronary risk only slightly higher than a diet based almost entirely on healthy plant foods, the researchers found.In other words, you don’t have to become a strict vegetarian to protect your heart.

On the other hand, overdoing “less healthy plant foods” and less healthy animal foods like red and processed meats, the study showed, significantly increased the risk of developing heart disease.On the other hand, overdoing “less healthy plant foods” and less healthy animal foods like red and processed meats, the study showed, significantly increased the risk of developing heart disease.
The Harvard findings lend further support to the most recently released Dietary Guidelines for Americans that urge people to consume large amounts of “high-quality plant foods,” the researchers noted. They added that the recommended diet “would also be environmentally sustainable” because plant-based food systems require fewer resources than those that rely heavily on animal foods.The Harvard findings lend further support to the most recently released Dietary Guidelines for Americans that urge people to consume large amounts of “high-quality plant foods,” the researchers noted.

Thus, the more plant foods and the fewer animal foods you eat, the lower your carbon footprint and the less you would contribute to animal suffering. But to be truly beneficial, the plant foods you choose must be rich in nutrients.Thus, the more plant foods and the fewer animal foods you eat, the lower your carbon footprint and the less you would contribute to animal suffering.

Although most Americans rely heavily on animal foods for needed protein, it’s not difficult to get quality protein on a vegetarian diet that contains dairy foods and eggs. Pescatarians, who add fish to such a diet, get a nutritious bonus of healthful omega-3 fatty acids along with high-quality protein from fish and shellfish.Although most Americans rely heavily on animal foods for needed protein, it’s not difficult to get quality protein on a vegetarian diet that contains dairy foods and eggs.

Those choosing a strict vegan diet — one devoid of all foods from animals — face a greater challenge because the protein in plants is not complete and must be balanced by consuming complementary sources, like beans and grains. A sandwich of almond butter or peanut butter on whole-grain bread is totally vegan and an excellent example of balanced protein in a high-quality plant-based diet. Vegans also must supplement their diet with vitamin B-12.

Short of becoming a vegan, you can improve your diet, protect your health and add variety to your meals by a few simple dietary adjustments. For example, as Dr. Hena Patel and Dr. Kim Allan Williams Sr., cardiologists at Rush University Medical Center in Chicago, suggested in a commentary on the Harvard study, you might choose one day a week to be meatless and gradually add more meatless days while adding one or more new plant-based recipes each week.Short of becoming a vegan, you can improve your diet, protect your health and add variety to your meals by a few simple dietary adjustments.
