But it's also important to eat different kinds of fruit and vegetables. Science shows that eating those of different colours is a great way to get enough nutrients(营养). It's called “eating the rainbow”.
The most important colour groups are yellow, white / brown, red, orange, purple / blue, and green.

We should eat at least one or two fruits or vegetables from each colour group every day.

For breakfast, you could have porridge or milk with strawberries, bananas and blueberries. That's red, yellow, and purple / blue. For lunch, you could have a salad with lettuce, carrots, purple cabbage, corn and red peppers. That's green, orange, purple / blue, yellow and red. Then for dinner, you could have cauliflower. It's white / brown.

In short, it's easy to eat healthily if we follow the rainbow diet.
