Doctor Dao Thi Yen Thuy, Head of the Department of Nutrition and Dietetics at Tam Anh General Hospital, Ho Chi Minh City, stated that curcumin is a prominent bioactive compound in turmeric. It can cross the blood-brain barrier to act directly on the central nervous system. This compound helps neutralize free radicals, reduce oxidative stress, and chronic inflammation—factors linked to brain aging, cognitive decline, and neurodegenerative diseases.

Curcumin also stimulates the production of brain-derived neurotrophic factor (BDNF). BDNF is a protein that nourishes nerve cells and promotes new connections between brain cells. Lower BDNF levels are associated with an increased risk of memory loss, dementia, and depression.

Curcumin can limit the accumulation of beta-amyloid plaques and abnormal tau proteins in the brain, two proteins that typically build up in individuals with Alzheimer's disease. However, curcumin does not replace medication.

Beyond curcumin, turmeric offers many beneficial vitamins, minerals, and plant compounds that improve blood circulation. Consistent blood flow to the brain ensures adequate oxygen and nutrients for nerve cells, supporting concentration and memory.

Doctor Yen Thuy noted that natural curcumin has low absorption. When preparing food, combine turmeric with a small amount of black pepper or vegetable oil to enhance its absorption.

Adults can use turmeric in meals three to four times each week. This should be part of a diet rich in green vegetables, fruits, fatty fish, nuts, and whole grains to boost brain health. Individuals using anticoagulants or antiplatelet drugs, those with a history of gallstones, or those preparing for surgery should consult a doctor before using turmeric or high-dose curcumin supplements.

In addition to dietary nutrition, individuals over 12 years old can supplement with natural extracts such as blueberry and ginkgo biloba. These can help combat free radicals and support increased blood circulation to the brain. This contributes to maintaining memory, cognitive function, and reducing the risk of stroke and dementia.

The doctor recommends that everyone maintain physical activity, get adequate sleep, control blood pressure, blood sugar, and blood fat, and limit tobacco and alcohol to protect brain health. People with risk factors like hypertension, diabetes, dyslipidemia, overweight, obesity, or a family history of stroke and dementia should have regular health check-ups, including nutritional consultations, to manage their conditions.
