PREVENTION AND TREATMENT
The following steps are ways to help prevent ADD and ADHD and to reverse the factors that cause them:
1) Change the child's diet to all natural whole foods. This means fruit, grains and vegetables full of natural vitamins, minerals and enzymes.
2) Eliminate dairy products and other animal products because these contain hormones, pesticides, antibiotics and the diseases of the animal itself.
3) Eliminate caffeine, sugar and other sweets, processed food, MSG, aspartame (Nutrasweet) and other sugar substitutes and any foods that contain preservatives, food dyes or other chemicals.
4) Eliminate eating at fast food restaurants as most of these apparently use MSG and preservatives, plus the food in many restaurants often contains less nutrition, but many harmful chemicals.
5) Encourage the child to eat a lot of raw fruit and vegetables because they are full of health-producing enzymes, vitamins and minerals.
6. Drink water, and fresh home-made vegetable and home-made fruit juice. Eliminate soda pop, caffeinated beverages or milk from cows or any other animal. Rice Drean (rice milk) from your health food store is a reasonable substitute.
7. No white bread. Only whole grain bread, either home baked or from a health food store.
8. No white rice. Only whole grain brown rice and other whole grains.
9. No peanut butter: It contains aflatoxin, a fungus that causes cancer. Instead use Almond butter (It spreads like peanut butter and tastes just as good) from your health food store or other store. Also you can make home-made cashew nut butter.
10. Get proper rest. Children need a lot of rest and should go to bed early.
11. Get proper exercise daily, outdoors in the fresh air and sunshine.
12. Eliminate TV watching. It is reported that children watch an average of 43 hours of TV per week, that's longer than the average adult work week. While watching, they rapidly become almost hypnotized. It has been shown scientifically that within minutes of beginning to watch TV, the brain changes from the alert brain waves (beta waves) to the hypnotic waves (alpha waves) where the judgment center of the brain is bypassed. So the violence and decadence that the child sees, bypasses the judgment center in the brain and is implanted in the child's brain without any ability on the child's part to decide whether what they are seeing is right or wrong. The violence and decadence are accepted by the brain without any moral judgment being applied to it. It then becomes part of the child's permanent subconscious. What goes into a child's mind is just as important as what goes into his or her mouth!
