Grains, fruits, vegetables, seafood, and herbs. Green tea. Nuts and vegetables are best snacks, as fruits are sweet and it's easier to have too much. Since dried vegetables usually don't taste appealing compared to fruits, it is often the fruits that get picked for trail mixes. Eggs are nice too if not cooked in tons of butter and covered with syrup or something ridiculous. If you just make a list of stuff you know isn't very good in large amounts, then avoid those... and make a list of stuff you know IS healthy, then try to eat more of that: should be okay. Refined sugar and flour is bad. Sodas are bad. Try go mostly natural and primarily seafood for meats. Occasionally just eating whatever you feel like (huge buttery steak with cheesecake and brownies on top)... Nice to indulge on occasion, but many do it day to day and suffer then die. Thanks, good luck.
