主题：Why are fruits and vegetables good for our health?

Eating a diet fortified with lots of fruits and vegetables - although sometimes unappetizing - ensures that you are getting the vitamins, minerals, and good fats your body needs to build strong bones, promote high energy, and keep things running to the best of your body's ability.

Fortify：强化
Unappetizing: 引不起食欲的
Mineral：矿物质
