Tuna ingredients lower blood pressure

A study by two companies in Shizuoka, Shizuoka Prefecture, Japan, confirmed that tuna peptides extracted from tuna's haematological meat have a rapid blood pressure lowering effect.

Japan’s “Daily News” reported last month that the two companies used special enzymes to decompose tuna's haze to make tuna peptides and feed 6 rats with high blood pressure in accordance with the standard of 0.1 g feeding at 1 kg body weight. It was compared with 6 hypertensive rats that did not ingest tuna peptides in the control group. After 6 hours, the high pressure values ​​of the rats consuming the tuna peptides were 14 mm Hg lower than the control group on average, and the average low pressure value was 8 mm Hg lower than the control group.

Hematological meat is the dark red part of the fish's rim and has high nutritional value. Under the background of high tuna prices worldwide, the above companies plan to use this research to develop new types of health foods. (According to Xinhua News Agency)
