Siden proteiner inneholder 8 essensielle aminosyrer som er livsviktige for kroppens funksjoner (facts, google it) - lurer jeg på hvor du får disse fra når du bare spiser frukt og grønnsaker?

Som sagt, les noen av bøkene så får du alle svar du vil ha. Jeg vil ikke sitte her å diskutere å lime inn svar i hytt å pine å mate deg. Les selv og lær selv

Proteins
When it comes to fruit and vegetables people tend to say: "But what about my proteins? I need them." We all know that we need proteins, because proteins are an important building material for our cells. We also know that meat, dairy and eggs contain many proteins, so we say that we have to eat meat, dairy and eggs to stay healthy. We have three arguments that prove that the human body doesn't need that much proteins:

The fruitarians;
Babies;
Amino acids.

- The fruitarians
The vegetarians (no meat), vegans (no animal products) and fruitarians (only fruit) do not consume food that contain many proteins. They live a healthy life without big doses of proteins and look younger too! Proteins are important though and the best source of protein is from the same raw fruits and vegetables that provide all the other nutrients: vitamins, minerals, enzymes and carbohydrates. Although fruit and vegetables contain less proteins than other nutrition, about 15 to 20 times less than for instance meat, the best way to get all these nutrients, including protein, is to eat a well-balanced variety of fresh, raw fruits and vegetables.
For the exact amount of proteins in fruit see: contents of fruit.
- Babies
When a baby is lucky enough to receive the most natural food it can get babies will be breast fed for the first three to twelve months of their lives. Mother milk contains not only the necessary nutritional elements but also protects the child against allergies and infections. It consists only of about 1% of proteins though proteins are the most important material for building cells! Babies grow lots of cells so obviously it's not necessary to obtain much of proteins for the cell-building process. Fruit also only consists of 1% of proteins and that is obviously enough proteins for a human to obtain the amino acids required for building the cells. Fruit doesn't contain much proteins but has everything in it to make fully grown humans and babies grow.
- Amino-acids
Proteins consist of amino acids and our body uses 20 different amino-acids. There are 8 amino-acids that our body cannot produce itself. They are called the essential amino-acids and our bodies have to obtain them through nutrition. There are many fruits and vegetables that contain all of the eight essential amino acids in the single fruit or veg. This means that it's not necessary to consume animal products to obtain the proteins that contain the essential amino acids our body needs. The following fruits and vegetables contain all 8 essential amino acids:
-Fruits: Bananas, tomatoes, cucumbers.
-Vegetables: Potatoes, sweet potatoes, carrots (also good for the memory), corn, cabbage, cauliflower, brussels sprouts, okra, peas, summer squash and kale.
