When you think of Okinawa, purple sweet potato tart comes to mind.
GRØN's protein blend -RED HEAT contains this "purple sweet potato" powder.

Because it is prohibited by the Plant Protection Act, purple sweet potatoes cannot be brought to Honshu, making them a food that can only be enjoyed in Okinawa.
These Okinawan island vegetables are vibrant and delicious, and are said to have many health benefits.
This "Purple Sweet Potato" powder was created using the latest technology in an effort to somehow convey this blessing.

Okinawa's purple sweet potato was brought over from China and began to be cultivated because rice and wheat were difficult to grow due to the frequent typhoons that caused damage to crops.
Okinawans, who live healthy and long lifespans even to the age of 100, eat purple sweet potato as their staple food, and research has shown that it makes up 67% of their diet, making it an ingredient that is so deeply rooted in their lives.

Red sweet potato is rich in dietary fiber, vitamins, and minerals.
It is said that having this as a staple food is closely related to the health and longevity of Okinawans and their good eyesight even in old age.

The secret lies in lutein and anthocyanin, a type of polyphenol that is abundant in purple sweet potatoes and has high antioxidant properties.
Lutein, which can be called "natural sunglasses," is said to have the effect of relieving eyes that become tired from the sunlight, including the strong ultraviolet rays that Okinawa receives.
It also contains four times as much anthocyanin as blueberries, which helps relieve eye fatigue and activate cells.
It is the perfect nutrient for modern people who strain their eyes by using smartphones and working on computers.

This is the maker, Mr. Nagai.
We value cultivation methods that use as little fertilizer as possible.

After the harvest, wheat is planted in the fields.
Adjust the soil nutrients in preparation for the next planting.

They work hard every day to provide delicious, safe food to as many people as possible.

A superfood made from island vegetables born from the Okinawan climate.
I realized that this is also a part of "Nuchigusui," and I felt that we wanted to create products that would help more people learn about these things.
