Over 30 million men in America suffer from ED, and the effect is not just physical. ED often takes a heavy emotional toll—eroding confidence, undermining self-esteem, and enveloping men in a cloud of depression. These emotional effects can cause problems with work productivity and lead to a loss of closeness and intimacy that can wreck marriages—it is even estimated that ED is a primary factor in one out of five failed marriages.

ED is a serious issue, and may even signal problems with cardiovascular health. However, a recent study offers hope. Researchers found that increasing your intake of certain fruits and vegetables can improve both blood flow and sexual performance. Along with that, certain supplements can act as an alternative to Viagra and other synthetic ED drugs, which may come with serious side effects. When low testosterone is found to be the cause of ED, bioidentical hormone replacement therapy has also been shown to be effective. Regardless of the cause, a new study finds men can treat or prevent ED with a simple change to their diet.
