All plant foods contain all essential amino acids.

所有植物性食物都含有所有必需氨基酸。

However, there are nine essential amino acids that you cannot make from others, and have to eat.

然而，有九种必需氨基酸是你没法从别的东西那里转换的，必须自主摄入。

In reality, most plant proteins do tend to have lower quality amino acid profiles, whether they lack a specific essential amino acid or just don't have sufficient amounts overall.

事实上，大多数植物蛋白质确实具有较低质量的氨基酸谱，无论是它们缺乏特定的基本氨基酸还是总体上没有足够的含量。

Now lots of foods don't provide every essential amino acid, but when you combine foods, like beans and rice, or pasta and cheese, you do get all of the essential amino acids.

很多食物不能提供必需的氨基酸，但是当你把食物混合在一起，比如豆类和米饭，或者意大利面和奶酪，你确实得到了所有必需的氨基酸。
