Yams have been “energetic food for men” since ancient times?
When you hear the words “energizing food,” many people may think of eel or garlic. But did you know that yams have actually been valued as an “energizing food” since ancient times?
The history of yams can be traced back to the Jomon period, when they were excavated from ruins, and they have a long history with the Japanese people.
In the ancient Chinese medical treatise “Honzo koumoku,” it appears under the name “sanyaku” (mountain medicine) and is described as effective as a tonic for nourishment.
Yams were also considered “energy-boosting” and were an important part of the diet of Japanese warriors and sumo wrestlers.
For example, it is said that warriors in the Warring States period ate yams to maintain their strength for long battles.
Why were yams considered an “energetic food”?
It is because nutrients such as “mucin” and “arginine” contained in yams help increase the body’s energy metabolism and maintain vigor.
Mucin is the sticky ingredient in yams. This ingredient has the following effects.
-Supports recovery from fatigue (easier to maintain stamina!)
-Improves sperm quality (aids male reproductive function!)
In addition, an amino acid called arginine improves blood flow and contributes to increased vitality.
Arginine is the so-called “natural Viagra” and is said to stimulate the secretion of male hormones.
In other words, yams are not only “energizing to eat” but also “useful for improving one’s constitution if continued for a long time,” making them a truly ancient Japanese energizing food!
It is also good for vegetarians! Yam is a plant-based energetic food
Some people want to improve their energy but don’t want to eat much meat or fish, or want to avoid animal products because they are vegetarians.
Yams are an excellent plant-based energizing food!
Generally, animal protein and zinc-rich foods (e.g., oysters, red meat, eggs, etc.) are considered to be good for increasing energy.
However, yams are rich in plant-based nutrients that are essential for increasing energy.

Why Yams Are Good for Vegetarians to Maintain Vigor
Arginine” increases energy!
Arginine contained in yams promotes the secretion of growth hormones and helps increase endurance.
It is also effective in recovering from fatigue after exercise, and is the perfect nutrient for those who feel that their stamina has been somewhat low lately.
Mucin improves the intestinal environment and increases absorption!
Mucin protects the gastrointestinal tract and supports digestion and absorption.
This allows other nutrients to be absorbed efficiently, ensuring energy even in a vegetarian diet.
B vitamins support metabolism!
Yams contain B vitamins such as vitamins B1 and B6, which promote energy metabolism.
This helps the body to become less fatigued and improves daily performance.
Iron prevents anemia and maintains vitality!
Iron deficiency is a point of concern, especially for vegetarians.
Yams contain non-heme iron, a plant-based iron, which helps prevent anemia and keep your body energetic.
How to eat yam & yam effectively?
If you are going to eat yam, an energetic food, you want to consume it in a more effective way. Simply eating it is a waste!
You can maximize the power of yams by being aware of “how to eat yams for more stamina”.
Raw” is the best way to eat yams! Make the most of mucin!
Mucin, the most important characteristic of yams, tends to break down when heated. Therefore, eating them raw is the best way to maximize their power!
We recommend “Tororo Gohan” or “Tororo Soba”. Combined with rice or soba noodles, the carbohydrates help the body absorb energy and maintain stamina for a long period of time.
Tororo + egg yolk → Rich in vitamin B group, improves energy metabolism
Grated yam + okra → Strengthens sticky ingredients and is gentle to the stomach and intestines
Grated yam + fermented food” improves intestinal activity and power
Yams are also effective in regulating the intestinal environment, so combining them with fermented foods further doubles their effectiveness!
For example, we recommend adding grated yam to miso soup. For example, adding grated yam to miso soup is recommended. It improves digestion and absorption and reduces the burden on the gastrointestinal tract while providing energy.
If you are going to cook them, it is best to grill or broil them on foil.
Some people may not like raw yams. In such cases, heating them to enjoy the crunchy texture is an option!
However, since mucin is lost when heated, it is important to cook them in a way that makes the most of arginine and B vitamins.
Grilled yam (butter + soy sauce) → Tastes delicious and goes well with rice
Sauteed yam (garlic + sesame oil) → Stamina type seasoning to strengthen your energy!
