Fans of this fizzy fermented drink claim it helps with everything from high blood pressure to diabetes and cancer. Kombucha is a mixture of black tea, sugar, bacteria, and yeast. Labels say these healthy germs boost immunity and bring down inflammation, though there isn’t much evidence to support the claims. But beware: If you don’t prepare this sour tea right and store it in the fridge, you could drink some bad germs along with the good.
Just one serving of greens a day can help slow mental decline as you age, research finds. Spinach, kale, and collard greens are rich in brain-friendly nutrients like folate and lutein. But you don’t need to eat them in salad form, or even on a plate, to reap their benefits. Blend 2 ounces of greens with berries, a banana, and ice for a rich, nutritious treat that’s also loaded with vitamins A and C.
This yellow spice is the main ingredient in curry, and it adds an earthy flavor to the tea. Turmeric has been a part of Chinese and Indian medicine for centuries. Thanks to its anti-inflammatory properties, turmeric is useful for skin, joint, and digestive issues. Researchers are now looking at its protective effects on the brain and whether it might improve memory and slow the progression of Alzheimer’s disease.
Beets are root vegetables. Their juice is high in antioxidants that protect against damaging substances in the body called free radicals. It also has nitrates that relax blood vessels and may help to reduce high blood pressure — a risk for stroke and dementia. Plus, this sweet and earthy juice helps fight fatigue.
This root has been a staple of traditional Chinese medicine for centuries. It may help increase stamina, boost concentration, and improve memory. Researchers are studying whether it could also protect against depression, Parkinson’s, and Alzheimer’s disease. Asian ginseng can cause side effects, including trouble sleeping. Because it can lower blood sugar, check with your doctor before using it if you have diabetes.
Cocoa is rich in flavanols, plant-based substances that help improve attention, processing speed, and memory. A cup of this rich brew might also protect against mental decline, especially in people who are at higher risk for dementia. Stick to dark chocolate, which has more flavanols than milk or white. And don’t overdo it. Chocolate is high in fat, calories, and sugar.
Your whole body needs water — including your brain. When you’re dehydrated, your mental function suffers. Water makes up 75% of your brain’s volume and acts as a natural shock absorber. Add a squeeze of lemon to your glass of water for both flavor and nutrition. Lemon has plant nutrients that protect your cells from damage. Plus, some people find that its scent improves their mood.
If a glass relaxes you, enjoy it. Red wine is high in natural chemicals that fight inflammation and protect cells in your brain from damage. Moderate wine drinking could help prevent the blood clots that can lead to stroke and reduce the risk of dementia. Just watch how much you drink. More than one glass a day for women and two for men can worsen brain changes and increase dementia risk.
These large white fungi get their name from their fur, which looks like a lion’s mane. A staple of Asian cooking and medicine, they are less popular in the United States. That’s a missed opportunity because research shows they protect brain cells and improve mild cognitive impairment — a decline in mental abilities that precedes dementia. Lion’s mane mushrooms make a good addition to tea.
