Black garlic is obtained from fresh garlic that has been fermented for a period of time at a controlled high temperature (60–90°C) under controlled high humidity (80–90%). When compared with fresh garlic, black garlic does not release a strong offensive flavor owing to the reduced content of allicin.
Enhanced bioactivity of black garlic compared with that of fresh garlic is attributed to its changes in physicochemical properties. Studies concerning the fundamental findings of black garlic, such as its production, bioactivity, and applications, have thus been conducted.
it does boast higher concentrations of many nutrients, antioxidants, and other beneficial compounds. These higher concentrations may be at least partly responsible for the many health benefits that black garlic provides:
Blood sugar control
Like fresh raw garlic, black garlic can help to regulate blood sugar levels. Reducing high blood sugar helps prevent serious health issues, such as diabetes symptoms, kidney dysfunction, and more. Higher antioxidant levels in black garlic may also help to prevent complications related to diabetes.
Fresh raw garlic is known for its ability to help improve heart health. Black garlic may provide the same protective effects. Black garlic can also help lower levels of cholesterol and triglycerides, which in turn reduces your risk of heart disease.
Fights some cancers
Many studies show that the antioxidant properties of black garlic can help to fight against cancer. One study found that it could help reduce the growth of colon cancer cells. Compounds in aged black garlic can also block free radicals in the body. This property reduces cell damage and can help to limit the growth and potential spread of cancer cells in the body.
