15. Citrus Fruits

Citrus fruits are high in citric and ascorbic acids. Although they are acidic, these fruits generate alkaline by-products and fans of the alkaline diet suggest they are alkaline. Lemons, oranges, limes, grapefruits, and tangerines are rich sources of vitamin C and supply generous amounts of vitamin A, potassium, magnesium, and folate. They also contain flavonoids that may help fight neurodegenerative conditions, diabetes, atherosclerosis, and cancer. Studies show that people who regularly drink 100% citrus juice (unsweetened and all-natural) have more favorable body measurement parameters than those who do not.

However, citric acid can erode the teeth. Dentists recommend consuming citrus fruits and beverages along with other low-acid foods and using a straw for beverages.
