Although there is no scientific research to back the claims of the alkaline diet, it is looked upon favorably by holistic doctors and some nutritionists who test pH levels through blood, saliva and urine. The diet tells followers to eat 70 to 80% alkaline foods and 20 to 25% acid foods. For alkaline foods, the higher the alkaline the better. For acidic foods, the lower the acidity the more benefits you will reap. High to moderate alkaline foods include: broccoli sprouts, cucumbers, kale, wheat grass, parsley, pumpkin seeds, buckwheat, avocado, almonds, lima beans, soy beans, cayenne, sea salt and red chili peppers. Foods with low acidity include: cow’s milk, wild fish, black beans, chickpeas, flaxseed, pecans, cantaloupe, dates and nectarines.
