What's best to eat then?

Almost all fruit and vegetables will count. Generally, raw vegetables and fruit will contain the most nutrients because cooking can remove some nutrients.

But frozen fruit and vegetables are still good, and dried fruit, such as currants, dates, sultanas and figs⁶.

几乎所有的水果和蔬菜都是算在内的。一般来说，生的蔬菜和水果将包含大多数营养，因为烹饪可能破坏某些营养元素。同样的，新鲜的水果和蔬菜被认为比腌制的更有营养。但是，冷冻水果，蔬菜和干果还是拥有好的营养价值的，如葡萄干，日期，葡萄干，无花果。

食品怎么样？
