Claimed mechanisms and health targets
According to the description, the foods are said to help fight oxidative stress, inflammation, blood sugar imbalance, cardiovascular decline, gut dysfunction and cellular aging. It names matcha's EGCG, natto's nattokinase and vitamin K2, anthocyanins in Okinawan purple sweet potato and astaxanthin in wild salmon as targeting what it calls the real mechanisms of aging. It also says the foods may support energy, brain health, heart health, metabolism, digestion, skin, immune function or overall lifespan. These are claims attributed to the creator, not results of a study described here.

Science framing in the description
The description says the foods are "backed by modern science" and that researchers have studied the lifespan of Japanese people, especially in Okinawa, called the Land of Immortals. It says what researchers found was food, not a miracle drug or supplement stack. However, it names no study, no participants, no comparison group and no measured outcome, so the description alone does not show how any food was tested or what was found.
