I have hypertension. i am doing sport and i'm trying to eat more fruits and vegetables. which kind of food should i prefer and which one to avoid?

Sensible: Fruits and vegetables are good. Include fish and limit red meat. I know that in Rwanda, potato may be popular (french fries) however I would limit this as well. Do not use alcohol regularly, beer or whiskey. In general, it sounds like you're on the right track! I would avoid fried and greasy foods and be attentive to the preparation of your food. Good luck!
