possibly having to do with its effectiveness in dieting? ANY ideas please! thanks!|||Science Fair has nothing to do with vegan-ism! It is Science not a lifestyle.|||Given the interest in green living, maybe it would be more effective for you to look at fossil fuel consumption or greenhouse gas emissions. Compare and contrast one or both of these things for a standard American diet and a vegan diet. If you want to do some extra work, consider adding in the pescetarian and ovo-lacto vegetarian diets as well. If you want to look at diet in particular, you could look at the rates of different cancers and/or obesity rates. All of these things are going to be based on doing research rather than experimentation, so be aware that if you are supposed to do an actual experiment, you might want to change your project a bit. For example, you could compare and contrast how people feel before, during, and after a meal that includes meat vs. a vegan one. Carefully plan the meals so that they are on par from a caloric standpoint.|||How about comparing a vegan to a meat eater and see who gets sick the most, has more energy, is healthier, etc.. :)
