Question

Richest source of protein is
A. Wheat
B. Sago
C. Soybean
D. Rice

Answer 1

Proteins are polymers of amino acids that are critical for our bodies to operate properly. One of the most abundant sources of edible proteins also contains large levels of estrogen-like compounds.
Essential amino acids are those that our bodies do not produce and must be obtained from outside sources.
Peanuts are another name for groundnuts, which are a type of legume. It is regarded as one of the greatest protein sources.

Complete answer:
Option A: In addition to the elements listed above, enriched wheat flour may be a good source of iron, thiamine, niacin, calcium, and vitamin B6. Selenium, manganese, phosphorus, copper, and folate, among other vitamins and minerals, may be found in whole wheat.
So option A is not correct.
Option B: Sago is a starch that is usually derived from the Metroxylon sagu palm. It's mostly carbs, with little protein, fat, fibre, vitamins, and minerals.
So option B is not correct.
Option C: The most protein-dense food is soyabean. Glycine max is the popular name for it. Soybeans also contain phytic acid, nutritional minerals, and vitamin B. It is a leguminous plant that aids in nitrogen fixation. Soy proteins are heat-stable and may be stored. It also generates oil. Wheat, rice, and sago are carbohydrate-rich foods that provide immediate energy.
So option C is correct.
Option D:Rice is one of the cereals with the lowest protein content $\left( {7\% } \right)$.
So option D is not correct.

So option C is the correct answer.

Note:
Kwashiorkor is a disorder caused by a protein shortage in infants aged one year or older.
Poor growth and mental development, swelling and edoema, and limb weakening are all symptoms of this condition.
Biofortification is used to prevent diseases like these. Crops with higher quantities of proteins, minerals, and amino acids are bred using this strategy.
