A few years ago, one of my patients asked me if I knew anything about Forks over knives. She reported she saw a cardiologist to get cleared for surgery, he told her he would not clear her but encouraged her to see the documentary Forks over Knives and to follow the diet. The patient was very stressing over the fact she could not get the surgery, she told me that the cardiologist encouraged her to eat a vegan diet. Vegans abstain from eating any animal products while vegetarians do not eat animal meat but still eat eggs, cheese, milk. The Forks over Knife documentary and book explores the claim that all deteriorating diseases can be control, even reverse by not eating animal based and processed foods.
Most people become vegan to avoid animal cruelty products and wanting to be healthier. But is a vegan diet Healthy? Around 2.5 percent of people in the United States (U.S.) are vegans, according to a 2016 poll. Here are some facts about the vegan diet:
The vegan diet contains only plant-based foods. All protein, vitamins, and minerals must come from non-animal sources, so food choice and preparation are important. Tofu, tempeh, and mushrooms are three of the many alternatives than can provide the nutrients found in meat. A vegan diet can help to protect bone and heart health, and lower the risk of cancer. Supplements are recommended to replace levels of certain nutrients abundant in meat, such as vitamin B12.
Animal fats have been linked to various cancers, diabetes, rheumatoid arthritis, hypertension, heart disease, and a range of illnesses and conditions. Animal sources are likely to account for 13 of the top 15 sources of cholesterol-raising fats in the U.S. Not eating meat reduces the overall risk of mortality.
The following are likely to be in short supply on a vegan diet, but alternatives are available.
- Vitamin B12: Vitamin-B12 fortified plant foods, such as fortified soy, seaweed, cereals, and nutritional yeast can supplement intake.
- Iron: Dried beans and dark leafy greens may be better sources of iron than meat on a per-calorie basis. Using a cast-iron skillet to prepare a meal is a good way to absorb more iron into the food.
- Calcium: Eat more tofu, tahini, and green, leafy vegetables.
- Vitamin D: Regularly consuming more vitamin-D fortified foods and spending time in the sun can boost vitamin D levels.
- Omega-3 fatty acids such as DHA and ALA: Omega-3 fatty acids, such as fish oil, are vital for cardiovascular health, eye function, and brain function. Though EPA, another type of omega-3, can’t be obtained with a vegan diet, ALA and DHA can be found in ground flaxseed, walnuts, canola oil, soy products, and hemp beverages.
- Zinc: Whole grains, legumes, and soy products are rich in zinc.
My patient followed the diet and lost around 20 lbs., reported feeling better, got off most of her medications and could get her surgery. The patient was not able to stick with the diet for more than 18 months, and has since started to eat meat again. While eating vegan can be healthy, making sure to get vitamin B12, iron, calcium, vitamin D, omega 3 acids and zinc; is important.
