Essential nutrients are very important elements that are needed in varying amounts by the body to allow for the smooth functioning of all processes within the body. Today, essential nutrients are thought to include vitamins, minerals, trace elements, amino acids, fiber as well as essential fatty acids.

​

All of these nutrients are found in fruit and vegetable foods. This is the basis of the recommendation from the health authorities to eat 5 portions of fruit and vegetables a day. Many of these valuable nutrients can also be found in nuts, wholegrain products, herbs, yeast, spices, green tea and even red wine.

​

必需营养素是维持身体正常运作非常重要的元素。如今人们认为，人体必需营养素包括维生素，矿物质，微量元素，氨基酸，纤维以及必需脂肪酸。 所有这些营养素都存在于水果和蔬菜食品中。

 

卫生组织建议，我们每天必须吃5份水果和蔬菜为营养的基础。许多这些有价值的营养素也可以在坚果，全麦制品，草药，酵母，香料，绿茶甚至红葡萄酒中找到。
