Eat fruit, vegetables & beans. The more fresh fruit & veggies you eat, the more natural vitamins and minerals you will get. You will also get the natural fibre into your body to help your digestive system from these food items. Make sure they're fresh.
Fish and chicken. These creatures provide natural oils and proteins and were provided by Mother Nature for this purpose. Even plants have spirits, so this is not a reason to become a vegetarian. Just give thanks for everything God put on this wonderful planet and don't be wasteful.
