The egg and grapefruit diet doesn't involve you only eating eggs and grapefruits for days on end. While that might cause you to lose weight and fast, it is not a healthy way of doing it and it doesn't include all the nutrients your body needs daily.
Yogurt contains lactobacillus, a good bacteria that helps fight bad bacteria in your intestines and vagina and helps your vagina stay in the optimal pH range. Eating yogurt regularly can prevent your vagina from becoming too basic, but it can also be used topically to cure a yeast infection or BV.
Removing the acidic level in your body and raising the ph level will help your internal organs. Using veggies and fruits to raise my ph levels, increase enzymes and a blender to puree foods (for faster nutrients absorbsion when digested). These are ways that I keep my disease in remission and maintain energy.
