What foods have all 8 essential amino acids?



After having been a vegetarian for over 14 years and a vegan for 3, can you believe I have ONLY JUST found out about amino-acids.
Apparently, there are 20 amino-acids in the body and 8 of them are “essential” for protein.
So, it’s not enough to eat things that have protein in them, such as beans, lentils etc, but we have to eat the right combinations of these to ensure we have all 8 amino-acids daily.
So, as I understand it, butter beans may only have 3 amino-acids and chick-peas might have another 5, but if they are not all different, we havent actually had the essential 8 building blocks that we need to build one full protein.

This does worry me, especially as my children are vegan too, and I want to make sure i dont see some deficiencies turning up later on.

Apparently one of my friends says that quinoa is the only food that has all 8 amino-acids in it. Of course I hate the taste of quinoa so much I almost cried!!!

But I was hoping someone on here might know something more on the subject and would be able to tell me the following:

a.
Is it true that quinoa is the “only” food that has all essential 8 amino-acids?

b. If not, do you know which other foods do?

c. Are there any supplements that can give us these?

Thank You so Much!!!

Sorry, forgot to say, what foods
APART FROM ANIMAL FLESH, EGGS AND DAIRY PRODUCTS
have all 8?
I want to stay healthy, not start drinking milk…. :-)
Goodygoodywitch,
FYI, lentils only have 6 amino-acids, so they cannot build a full protein.
Rice has only 7, hence that is also not a full protein.
But thanks for the TOFU tip! That seems to be right! (But does tofu contain cow’s milk???)

milk has all 8

You don’t have to eat them at the same sitting (but if you want to feel full you should), but eat them at least in the same day.

Goji Berries are the only fruit or vegetable on the planet that have all 8 essential amino acids (plus 11 more)

They taste great, but sense they come mainly from Tibet, you can only find them dried in packages, kinda like raisins.

you don’t need to eat all 9 essential (which actually means we can’t produce them ourselves) in the one ingredient.

rice and legumes don’t have the same amino acids in them and combining them gives you high levels of all essential 9.

amino acids are in all foods at different levels and different types.

the vegan society has great tips and in-depth books if you need it

There are only a few sources of perfect plant protein. Most plants have incomplete protein- that is, they lack all 8 essential amino acids. SOYA and QUINOA are the exception to the rule, as these provide all 8 essential amino acids, and as such are complete proteins. Anything made from soyabeans (tofu, soymilk, etc) is a perfect protein.

Protein needn’t be a worry if you’re eating a variety of plant sources, because in combination, plant foods can provide all 8 essential amino acids.

In most grains and seeds, the limiting amino acid is lysine, while in most pulses it is methionine. Tryptophan is the limiting amino acid in corn (maize). Most plant foods have a limiting amino acid, but by eating a balanced diet you’ll get a complete protein. To answer your last question – no, you don’t need protein supplements – they are unsafe and unnecessary. It’s FAR healthier to get protein from food.

The foods which commonly supply the most protein in a vegan diet are pulses (peas, beans, lentils, soya products), grains (wheat, oats, rice, barley, buckwheat, millet, pasta, bread), nuts (brazils, hazels, almonds, cashews) and seeds -sunflower, pumpkin, sesame. :)

There are actually nine essential amino acids.
Eggs contain all nine amino acids, plus all three essential fatty acids. Other complete sources come from animal products.
Plants are usually deficient in at least one. Consume a variety to obtain all nine.

“The nine essential amino acids are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan and valine. There was once speculation that histidine could be synthesized by the body, but after conducting scientific studies, the World Health Organization in 1975 decided this could not be proven and declared histidine essential. “

Folks, this protein mythology must be extinguished! No human beign ever need to worry about so called Complete and incomplete proteins. All plants contain the amino acids we need. Some contain lower amounts of one amino acid while higher levels of another, when compared to another plant food. In the end our body has a pool of amino acids that it draws upon. The fact is Americans are obsessed with protein and the average American, according to the USDA eats 3-4 times their actual daily protein needs. Just think of human beings in Nature. No calculators, no charts.If you eat enough varied plant-based calories for your needs you will get adequate protein. It’s that simple.

Unlike carbohydrates and fats, excess amino acids are not stored, but are converted into other metabolites or are used to make energy. There are 20 amino acids but only 9 are essential because the other 11 (non-essential amino acids) can be made from other precursors or amino acids (essential) provided from the diet. For example, tyrosine is non-essential because we can make it from phenylalanine, but phenylalanine is essential.

the plant Moringa and Quinoa are the only plants known to have all essential amino acids. Milk(whoever posted is NOT a veg).
