The immensely popular Simply Vegan is now available in a Fourth Edition. Simply Vegan is much more than a cookbook. It is a guide to a non-violent, environmentally sound, humane lifestyle. It features:
Quote from a well-known vegetarian activist: "This book truly is the Bible of veganism. I have found it to be an indispensable reference source for combating the ignorance and misinformation that one often encounters as an activist for health, animals, and the environment."
Simply Vegan is more than a cookbook. It is a guide to a non-violent, environmentally sound, humane lifestyle.
Long ago, I became vegan for ethical reasons. As a graduate student studying International Relations at Georgetown University, I often found myself having to justify my strong beliefs in pacifism. In course after course on foreign policy making, I felt that I was the only one in my graduate class who saw war as the last option for settling disputes. With the exception of one other classmate from Venezuela, I was the only student who truly believed in promoting non-violence.
One evening as I sat around the dinner table with several non-vegetarian classmates, one person asked me if I ate meat. I replied, "yes." To which he added, "Isn't killing animals for food a violent act?" My response was that animals are not people. However, after that evening's discussion I immediately became vegetarian. I quickly realized that killing animals for food was not only unnecessary and inconsistent with my own non-violent lifestyle, but that raising animals for food was destroying our environment and in many cases ruining our health, too.
As time goes on, I find that eating a vegan diet, using ecologically sound products that have not been tested on animals, and wearing clothes made from non-animal sources is not difficult, as long as you know where to shop for these items. Six years ago I saw the need to create a convenient guide to vegan living. Simply Vegan is that resource. Now in its fourth edition, I hope this book makes your life simpler.

Summary: Dried beans and dark green leafy vegetables are especially good sources of iron, even better on a per-calorie basis than meat. Iron absorption is increased markedly by eating foods containing vitamin C along with foods containing iron. Vegetarians do not have a higher incidence of iron deficiency than do meat eaters.
Iron is an essential nutrient because it is a central part of hemoglobin which carries oxygen in the blood. Iron deficiency anemia is a worldwide health problem which is especially common in young women and in children.
Iron is found in food in two forms, heme and non-heme iron. Heme iron, which makes up 40 percent of the iron in meat, poultry, and fish is well absorbed. Non-heme iron, 60 percent of the iron in animal tissue and all the iron in plants (fruits, vegetables, grains, nuts) is less well absorbed. Vegan diets only contain non-heme iron. Because of this, iron recommendations are higher for vegetarians (including vegans) than for non-vegetarians. The RDA for iron is 14 milligrams per day for vegetarian men and for women after menopause, and 33 milligrams per day for women prior to menopause (1)
Some might expect that since the vegan diet contains a form of iron which is not that well absorbed, vegans might be prone to developing iron deficiency anemia. However, recent surveys of vegans (2, 3) have shown that iron deficiency anemia is no more common among vegetarians than among the general population although vegans tend to have lower iron stores (3).
The reason for the satisfactory iron status of many vegans may be that commonly eaten foods are high in iron, as Table 11 shows. In fact, if the amount of iron in these foods is expressed as milligrams of iron per 100 calories, many foods eaten by vegans are superior to animal-derived foods. This concept is illustrated in Table 12. For example, you would have to eat more than 1700 calories of sirloin steak to get the same amount of iron as found in 100 calories of spinach.
Another reason for the satisfactory iron status of vegans is that vegan diets are high in vitamin C. Vitamin C acts to markedly increase absorption of non-heme iron. Adding a vitamin C source to a meal increases non-heme iron absorption up to six-fold which makes the absorption of non-heme iron as good or better than that of heme iron (4).
Fortunately, many vegetables, such as broccoli and bok choy, which are high in iron are also high in vitamin C so that the iron in these foods is very well absorbed. Commonly eaten combinations, such as beans and tomato sauce or stir-fried tofu and broccoli, also result in generous levels of iron absorption.
It is easy to obtain plenty of iron on a vegan diet. Table 13 shows several menus which would meet the RDA for iron.
Both calcium and tannins (found in tea and coffee) reduce iron absorption. Tea, coffee, and calcium supplements should be used several hours before a meal that is high in iron (5).
