Dis-ease of the body usually starts when our internal environment becomes acidic and begins to heal again when the body becomes more alkaline. The optimum pH level for health is around 7.3-7.4, and can be maintained if your diet consists of about 75% vegetables (including lots of leafy greens), fruits, and sprouts and 25% of beans, grains, nuts, and seeds.
For those who eat animal protein, it can be very acidic to the body so be wise by choosing humainly raised, grass fed/free range lean cuts of meat and keeping them to a small percentage of your overall diet. Whenever possible, try to buy organic alkaline foods, fruits and vegetables that are grown in organic, mineral-dense soil, as they tend to be more alkalizing. Research shows that the type of soil that plants are grown in can significantly influence their vitamin and mineral content. Fresh fruits and vegetables promote alkalinity the most. Try to consume a good percentage of your produce raw, as uncooked fruits and vegetables are said to be biogenic or alive. Cooking foods depletes alkalizing minerals. Increase your intake of raw foods, and try juicing or lightly steaming fruits and vegetables.
For beverages, adding lemon, lime, or baking soda to your water can also boosts its alkalinity, and consuming green drinks made from green vegetables and grasses in powder form are loaded with alkaline-forming foods.
