To achieve the acid/alkaline balance in the body we should consume a 80/20 mix of alkaline/acid foods.
Another method to help alkalize your body is to drink alkaline water.

ALKALINE WATER:
This type of water has a higher pH level than does tap water. Some proponents say that alkaline water can neutralize acid in your bloodstream, boost your energy level and metabolism, and help your body absorb nutrients more effectively. Others say that alkaline water can help you resist disease and slow the aging process.

Examples of acid foods
