Vegetables, fruits, beans, and nuts. That's it, and that's all. No refined grains of any kind - that includes bread or rice. No animal products of any kind - that includes fish. Fish is not a vegetable, fruit, bean, or nut. No oils. That means I can't eat hummus or most Italian food. Basically, if it's in a restaurant, chances are I can't eat it, unless it's a Hollywood natural-foods restaurant or an all-you-can-eat salad bar where I can skip the dressings and just get the actual food. No alcohol, because alcohol is almost identical to sugar in terms of how it metabolizes. No dried fruit, because the drying eliminates almost all the nutrients and leaves only sugar behind. No roasted nuts, only raw, for a similar reason.
Basically, if a rabbit wouldn't eat it, neither will I.
Although my diet is vegan the goal is not saving the adowable fuzzie-wuzzies. The goal is surviving heart disease. (I've had heart surgery, and I am very young for that sort of thing.) Avoiding meat matters, but nutrient density matters much more. Many vegan meals are not something I can eat, because they depend on heavily processed meat substititues. For example, Amy's Organic Vegan Chili, although it is delicious, is probably every bit as bad for me as a hamburger from In N Out. Possibly even a little worse, if you get the burger with no cheese and no condiments except pickles. The chili's saturated fat content is unbelievable - something like 30% of what the government says is your recommended daily allowance. My favorite doctor sets the recommended daily allowance at zero.
Most days I eat beans cooked with lots of vegetables, and staggering amounts of raw fresh fruit, tomatoes, and romaine lettuce. It's delicious, simple, and easy. There isn't anything difficult about it. It's less complicated than the way I used to eat, faster, easier, and cheaper - especially since I used to eat out every day, instead of cooking - and it eliminated a lot of my cholesterol problems. With this diet, plus statin medications, I saw at least the same amount of cholesterol improvement in three months that my father and my uncle each saw after ten years of statin medications only. (I think I actually saw a slightly better improvement when it comes to LDL cholesterol, and a significantly better improvement when it comes to triglycerides.) I've also lost around 30 or 40 pounds, and am still losing weight (which is good because I was technically obese and am not so any longer).
Protein intake is not a problem. Discussing it does not interest me. Long story short: read up on the science. I will say the only interesting thing I know about the subject: herbivore digestive systems are long and complicated, because vegetables are full of nutrients, and digesting them takes time. Carnivore digestive systems are short and simple, because meat is full of toxins, but simple to digest. In a normal human being, the digestive system involves more than 20 feet of travel. We have the ability to digest meat, and we have a long and complicated digestive system.
