10 Plant-based protein sources in Japan

If you are an exercise fanatic the question of “how much protein is enough” has certainly crossed your mind more than once, but even if you are not so sporty, it is good to understand the importance of protein and the role it plays in our lives. Furthermore, Anyone who eats a vegan or vegetarian diet is sure to have doubts about how much plant-based protein they are getting through their dietary choices, with the looming stereotype being that plant-based diets are in dire need of protein supplementation. However, as we will discover there are a great number of protein rich foods available to the vegan diet as we explore 10 Plant-based protein sources in Japan.

What does protein do and why do you need protein in your diet?

Protein is incredibly important for the body and a key element of your diet. It is so important, that protein is classified as a “macronutrient”, and like the other two macronutrients, lipids (fat) and carbohydrates (sugar), we need a lot of them to survive. “Micronutrients”, on the other hand, such a vitamins and minerals, are needed in lesser quantity.

Protein, contrary to the other two macronutrients, is not stored in the body, and thus requires its quota to be met through diet. Protein plays a vital role in the structuring of your body, as it is used to build bones, muscle, skin and cartilage, produce blood cells, repair tissue, and make bodily chemicals, enzymes, and hormones.

How much protein is needed for the average man and woman vs someone sporty?

The actual amount of baseline protein your body requires depends on a few factors, such as age, gender, physical activity levels, and body size, so the following numbers are only a guideline. The RDA (recommended daily allowance) of protein in the U.S. follows the simple calculation of about 0.8 grams per kilogram of bodyweight.
At the top of the list come adolescent boys and active men, clocking in at around 1.2 to 2 grams of protein per kilogram of body weight. This puts a sporty 68 kg man at around 80 to 130 grams of protein per day. An average sedentary male should be able make due with around 55 grams per day. Average sedentary women and young children on the other hand should try to take in about 45 grams, while active women and teen girls should aim for around 55 to 115 grams of protein per day depending on levels of exercise.

Sporty individuals are in particular need of extra protein due to its muscle repairing properties, helping to maintain and build muscle mass. As a rule of thumb, the more you work out and the higher the intensity of the exercise, the more protein you will need.
