The word “protein” is derived from a Greek word which means “the most important thing” . Protein is a vital nutrient which makes up approximately 20 % of the human body, which is second only to water (about 70 % of that) .
Protein is composed of 20 kinds of amino acids, and it is not only the main component of muscle, organs, bones, skin and hairs, but also the principle ingredient for hormones, enzymes, antibodies and so on, so that protein helps to grow your muscle, to boost your immune system and metabolism, and to develop your brain and body.
According to the dietary reference intakes for Japanese (2020) by Ministry of health, labor, and welfare, an adult male is recommended to have 65g protein a day, and for an adult female, 50g protein a day. That means a man has to have 10 eggs a day if he fulfils that standard intake only with eggs, and a female needs 7eggs a day. Only with milk, a man needs to drink 10 cups a day (200g a cup), and a woman needs 7 cups. For those who exercise, it is highly recommended to have more than twice.
The secret of our distinctive taste,
something more than nutrients
