WFPB vegan diets especially those with no oil are not the same as vegetarian or pescatarian diets or vegans who eat potato chips and Oreos.

Perhaps even more tellingly, people who followed a healthful plant-based diet but included more animal foods still staying below six servings a day were less likely to die than those who followed the highly processed unhealthful plant diet uPDI. More people would be able to adopt these moderate dietary changes and hopefully benefit from them rather than extreme changes. Rather, they should encourage those who eat animal products to focus on eating healthy foods and keeping their meat intake at a minimum.

But those criticisms come with any investigation into nutrition. Focusing on eating unprocessed vegetables and the like as much as possible—with some meat and animal products sprinkled in—could be a much more sustainable plan for Americans accustomed to the omnivorous lifestyle. There are no vegetarian snakes. They eat frogs, rabbits, and eggs. Even predatory ladybugs eat aphids and other pest insects. When it comes to humans, however, some vegetarians believe that killing animals for food is immoral and harmful to the environment that supports them.

Everyone should feel a moral twinge when it comes to factory farmed animals. Most are indeed treated cruelly beyond what any living thing should be made to endure. Animals raised in CAPOs are often malnourished, hungry and thirsty, in pain, injured or diseased, live in distress, and cannot express their natural behaviors.

This has a direct affect on their nutritional density. Calves, for example, are birthed from the existing herd and the rancher knows each animal personally. Eating plants definitely has its benefits. Meat contributes greatly to our overall health and contains many nutrients that cannot be obtained in any amount from plants.

Paleo principles do not condone eating factory farmed cattle or milk cows, industrial poultry, or other animals who do not graze freely. Grass fed animals graze on untreated fields and eat weeds, grasses, shrubs, insects, and grubs which eliminates bowel distress and the accompanying methane gas emissions caused by a grain diet.

Although green leafy vegetables contain some vitamin K, vegans may also need to rely on fortified foods, including some types of soy milk, rice milk, organic orange juice, and breakfast cereals. They may also want to consider taking a vitamin D supplement. Becoming a vegetarian requires planning and knowledge of plant-based nutrition. Here are some resources that can help:. American Dietetic Association www. The Vegetarian Resource Group www.

Vegetarian Society of the United Kingdom www. Research shows that lacto-ovo vegetarians generally get the recommended daily amount of protein, which is easily obtained from dairy products and eggs. Women need about 0. Because the protein in vegetables is somewhat different from animal protein, vegans may need 0. There are many plant sources that can help vegans meet their protein needs, including peas, beans, lentils, chickpeas, seeds, nuts, soy products, and whole grains for example, wheat, oats, barley, and brown rice.

Vegetarians used to be told that they had to combine "complementary" plant proteins rice with beans, for example at every meal to get all the amino acids contained in meat protein. Now, health experts say that such rigid planning is unnecessary. According to the American Dietetic Association, eating a wide variety of protein sources every day is sufficient.

Vitamin B Vitamin B 12 is found only in animal products, but those products include dairy foods and eggs, so most vegetarians get all they need.

If you avoid animal products altogether, you should eat foods fortified with vitamin B 12 certain soy and rice beverages and breakfast cereals or take a vitamin B 12 supplement to avoid a deficiency, which can cause neurological problems and pernicious anemia.

Studies show that in Western countries, vegetarians tend to get the same amount of iron as meat eaters. But the iron in meat especially red meat is more readily absorbed than the kind found in plant foods, known as non-heme iron.

The absorption of non-heme iron is enhanced by vitamin C and other acids found in fruits and vegetables, but it may be inhibited by the phytic acid in whole grains, beans, lentils, seeds, and nuts. Phytic acid in whole grains, seeds, beans, and legumes also reduces zinc absorption, but vegetarians in Western countries do not appear to be zinc-deficient. Omega-3 fatty acids. DHA-fortified breakfast bars and soy milk are also available.

Official dietary guidelines recommend 1. Good ALA sources include flaxseed, walnuts, canola oil, and soy. As a service to our readers, Harvard Health Publishing provides access to our library of archived content. Please note the date of last review or update on all articles.
