You can eat these foods as much as you like! Aim to have 70-80% of your diet filled with these foods.
All raw foods: Ideally try to consume a good portion of your produce raw. Uncooked fruits and vegetables are said to be biogenic or "life-giving." Cooking foods depletes alkalizing minerals. Increase your intake of raw foods, and try juicing or lightly steaming fruits and vegetables.
Alkaline water: Alkaline water has a pH of 9 to 11. Distilled water is just fine to drink. Water filtered with a reverse osmosis filter is slightly acidic, but it's still a far better option than tap water or purified bottled water. Adding pH drops, lemon or lime, or baking soda to your water can also boosts its alkalinity.
Green drinks: Drinks made from green vegetables and grasses in powder form are loaded with alkaline-forming foods and chlorophyll. Chlorophyll is structurally similar to our own blood and helps alkalize the blood.
