The less nitric oxide the body produces, the more it is destroyed.

For example, too much saturated fat can damage nitric oxide,

This may lead to obesity, diabetes and heart disease. A diet with low saturated fat and high unsaturated fat is very good and can protect nitric oxide. Similarly, fish and fish oil are also important for keeping healthy. Grape juice, garlic, green tea, dark chocolate and other foods can effectively improve the level of nitric oxide in the body, and appropriate exercise has the same effect.
