How can i improve my man's hood health problem?

My main food at home is cabbage and some green veg. I do sports every 2days but after some few weeks back I started to notice some changes like my men's power cant wokeup in the early morning time, when ever i sit there and start to think about my girl nothing work. I like veg food, it makes me look clean and sexy....I dont know what I can do about my health.
