I don't eat vegtables just corn and patatoes what should i do ?

Learn to love: Technically, potato is not a vegetable, its a tuber. And corn has far less nutritional value than other vegetables. There are so many terrific vegetables out there, try them all. Go to ethnic super markets that carry more unique vegetables. Find ways to prepare them to your liking. Ultimately, if you can convince yourself its for better health, mind will conquer taste buds!
