What do vegans eat and avoid? Vegans avoid all animal‐derived foods – so as well as meat and fish, that means no eggs, dairy or honey. They also exclude animal byproducts like rennet used in cheese making, gelatin in desserts and certain E numbers including the red food dye cochineal (E120). Even certain vegetarian foods, such as some meat substitutes, are off the menu because they contain egg and sometimes dairy.
Vegan diets are rich in fiber, vitamin C and folate (thanks to all that fruit and veg), but you may be lacking in a number of other vitamins and minerals. Vitamin B12 is a good example. We need it for healthy red blood cells and nerve function, but because it’s typically found in animal foods like eggs, milk and cheese, full-time vegans need to include fortified breakfast cereals and soy products, and possibly consider taking a B12 supplement look for one that supplies 10 micro-grams daily).
In another study, published in the American Journal of Clinical Nutrition in 1999, researchers tracked 45 people: 20 meat-eaters and 25 vegans who had been following the approach for an average of 12 years. Body mass index was appreciably lower among the vegans, nine of whom had a BMI of below 19, the researchers found; a BMI below 18.5 suggests a person is underweight. More than 60 overweight, post-menopausal women were split into two groups: Half followed a vegan diet, and the other half followed a National Cholesterol Education Program diet (low in fat and dietary cholesterol). After a year, vegan dieters lost more weight than did the NCEP group: 10.8 pounds compared with 3.9 pounds. The pattern held up after two years, when the vegans still weighed 6.8 pounds less than they did when the study began, compared with 1.8 pounds for the NCEP group, according to findings published in 2007 in Obesity.
