Neal Barnard, MD is a doctor, clinical researcher, and founding president of the Physicians Committee for Responsible Medicine, an international network of doctors and scientists. The below answers come directly from him, unless otherwise indicated.
A plant-based diet easily provides all the protein the body needs. There is no need for meat, dairy products, or eggs for protein, and you are better off without them. Vegetables, grains, and beans give you plenty of protein, even if you are active and athletic.
And there is no need to eat these foods in any special combinations. The normal mixtures of food people choose from day to day easily satisfy protein needs. For people who like technical details, protein is made up of amino acids. Each amino acid molecule is like a bead, and many amino acids together make up the protein chain. There are many different amino acids, and all of the essential ones are found in plants. And by all means, do not fret about protein grams or feel any need to count them.
But if you are interested in the numbers, simply divide your body weight in pounds by three. That gives you an approximation of the number of grams of protein your body needs, plus a margin for safety.
So, for example, for a person who weighs pounds, 40 grams of protein is more than enough on a daily basis. Some experts believe that the actual amount of protein required is actually much less than this figure. The bottom line is to have a healthful mix of vegetables, beans, whole grains, and fruits, and protein takes care of itself.
These foods also bring you calcium and other important minerals. Vegetables, beans, and other foods provide all the iron you need. In fact, studies show that vegetarians and vegans tend to get more iron than meat-eaters. Vitamin C increases iron absorption. Dairy products reduce iron absorption significantly. To go into a little more detail, there are actually two forms of iron. Plants have nonheme iron, which is more absorbable when the body is low in iron and less absorbable when the body already has enough iron.
This allows the body to regulate its iron balance. On the other hand, meats have heme iron, which barges right into your bloodstream whether you need it or not. The problem is that many people have too much iron stored in their bodies.
Excess iron can spark the production of free radicals that accelerate aging, increase the risk of heart disease, and cause other problems.
If your energy is good and your hemoglobin and hematocrit are at the low end of normal, that is likely the best place to be. Having said that, you will want your doctor to review your laboratory results and to track them over time. If your hemoglobin and hematocrit are dropping, that may be a sign of blood loss. That can be from benign causes, such as menstrual flow, but can also reflect more dangerous health issues, such as intestinal bleeding.
The same green leafy vegetables and legumes that provide iron are also good sources of calcium, for the most part, and absorption is typically better from these sources than from dairy products.
If you like, you can also use calcium-fortified products such as breakfast cereals and juices, although these products provide more concentrated calcium than is necessary. It pays to put some thought into keeping your bones healthy. Studies have shown that the following factors are helpful in building and maintaining strong bones:. Getting plenty of exercise. Getting enough vitamin D. Eating plenty of fruits and vegetables.
People who eat lots of vegetables and fruits are less likely to have bone breaks. Part of the reason may be that they contain vitamin C, which is essential for building collagen, the underlying bone matrix.
Studies have shown that women who smoke one pack of cigarettes a day have 5 to 10 percent less bone density at menopause than nonsmokers. Soy products have been around for thousands of years and are a dietary staple in many regions of Asia. Research has shown that people in these regions have lower rates of heart disease, breast and prostate cancer, fewer hip fractures and fewer hot flashes.
In addition, dozens of clinical studies have supported health benefits of diets rich in soy. Some have raised the question as to whether soy has untoward effects.
Happily, these concerns have been set aside. Girls who consume soy products in adolescence have about 30 percent reduction in breast cancer risk as adults.
Women previously diagnosed with breast cancer have a significantly greater survival if they include soy in their diets, compared with women who tend not to use soy products.
However, if a person is uncertain or simply does not want to include soy, I always remind them that a vegan diet does not mean joining the Soy Promotion Society. A vegan diet can mean many things: Soy products come from an Asian tradition and are totally optional. I hear so many concerns about soy, so here are a few of the tweets and blogs that might help you make your decision about whether or not to eat it I certainly do!
Says veg-fruit-soy is supreme! The soy controversy has some clarity! Same true for breast and prostate cancer. Looks good, so enjoy! Again, eating a diverse diet of whole grains, beans and legumes, fruits and vegetables will give you everything you require in terms of protein. As for allergies, in some cases, they will change over time. For example, it is very common for children to have allergies that disappear as they get older, and that occurs in adulthood, too.
Also, quite often, allergic responses diminish when people stop consuming dairy products. For example, a person who is allergic to cats or as asthma symptoms in response to pollen will find that these symptoms diminish when they leave dairy products aside. ALA alpha-linolenic acid is a basic omega-3 fat that can be converted in the body to the other omega-3s the body needs.
ALA occurs in small amounts in beans, vegetables, and fruits, and this should be all the body needs. If more is desired, it is also found in walnuts, soy products, and, in high concentration, in flax seeds and flax oil. If these are used, there is no need for more than minimal amounts.
If you are looking for more, for whatever reason, health food stores sell vegan omega-3 supplements. There are major health issues with eggs. First, the yolk is where cholesterol lurks—more than milligrams in one egg. There is also about 5 grams of fat in a single yolk. Egg white is essentially solid pure animal protein. Its main problem is that the kidneys have trouble eliminating animal protein by-products.
An year Harvard study showed that kidney deterioration is accelerated by animal protein for anyone who has already lost any degree of kidney function , whereas plant protein does no harm to the kidneys. It also tends to cause the body to lose calcium, just as other animal proteins do. If it is hard to believe that there really is so much fat, cholesterol, and animal protein inside a single egg, keep in mind that an egg contains all the parts to make a complete chicken.
The building blocks for the beak, bones, feathers, and everything else are inside that egg when it is laid, and they simply rearrange before the egg hatches.
Yes, avoiding meat definitely helps improve blood sugar. People who avoid meat are much less likely to develop diabetes and those who avoid all animal products are even less likely to do so.
And, in clinical trials, people who make these same diet changes have dramatic improvements in blood sugar control. The most comprehensive study was our NIH-funded study, but other teams have found similar results. Diabetes is obviously a serious condition, and a healthful diet is key to its management. If you have type 2 diabetes, a low-fat vegan diet is the diet of choice. It offers the best chance of reducing or eliminating your medications, and will help prevent complications.
Many people with diabetes are nervous about the fact that a plant-based diet increases their carbohydrate intake. The answer is not to turn to fatty, high-protein foods that increase the risk of cardiovascular and renal complications. Rather, the answer is to choose whole grains, legumes, vegetables, and fruits, focusing on low-glycemic index foods ie, those that have minimal effect on blood glucose.
The details are found in Dr. I am just beginning to eat vegan but am experiencing a lot of gas; how do I deal with this? If the problem is gassiness, beans are a common culprit. They should not be excluded from the diet, however, because they are great sources of protein, calcium, and iron, among other nutrients. But if you are new to beans, it is good to have them in small portions and always very well cooked. A well-cooked bean is very soft, with no hint of crunchiness. As time goes on, your digestive tract adjusts, so a bean that may cause a problem today may be better tolerated later on.
Also, cruciferous vegetables can cause indigestion for some people. The answer is simply to cook them well.
This group includes broccoli, cauliflower, Brussels sprouts, kale, and cabbage, among others. It is common for people to eat them raw or only slightly cooked, but they can easily cause gassiness or bloating. Cook them well, and the problem usually disappears. Later on, you can experiment again with less-cooked vegetables. On the good side, rice is very easily digested, and a great food to emphasize.
