Comparing exercise to curcumin

The study included 32 healthy but sedentary postmenopausal women, divided into three groups: a group assigned to take 150 mg of curcumin per day; a group assigned to engage in exercise training three or more days per week; and, a control group that did not exercise or take curcumin.

Tests to measure blood vessel function were done at the beginning of the study and after eight weeks. These tests showed the following:

• Systolic (the higher number) blood pressure dropped in women in the curcumin and exercise groups but not the control group.
• Tests measuring blood vessel elasticity improved in exercisers and curcumin users but there was no change in women in the control group.
• Changes in blood pressure and vessel elasticity were similar in women who exercised and women who took curcumin.
• HDL (“good”) cholesterol levels”) and fitness testing improved only in the exercisers.

Curcumin may be as good as exercise for blood vessels

Starting an exercise program and taking the curcumin supplement were both associated with similar benefits on blood vessel function in the women in this study. “These findings suggest that curcumin could be [used] as a therapeutic strategy for the treatment of cardiovascular disease similar to exercise training in postmenopausal women,” the study’s authors said; however, the findings also unsurprisingly suggest that exercise may have advantages related to improved fitness that could contribute to a wider range of overall health benefits.

An anti-inflammatory lifestyle

Curcumin—a plant chemical known as a flavonoid—has strong antioxidant and anti-inflammatory properties, which are likely to be responsible for its positive effects on cardiovascular health. Exercise strengthens the muscles of the heart and artery walls and promotes circulation, which can lead to reduced inflammation. Combining curcumin with regular exercise might bring about a greater benefit than either alone, but researchers have yet to examine this.

Here are some other ways to reduce oxidative damage and inflammation and improve your heart health:

• Include colorful vegetables. A diet high in red, yellow, and green veggies like tomatoes, squash, and kale is rich in antioxidants and protects against heart disease as well as other chronic diseases.
• Use olive oil. Olive oil is an important part of the heart-healthy Mediterranean diet. Like curcumin, olive oil has anti-inflammatory and antioxidant properties and has been shown to increase vascular elasticity.
• Eat fish. The polyunsaturated fats from fish are strongly anti-inflammatory. Eating fish and taking fish oil have both been found to protect the cardiovascular system. Eating meat, on the other hand, increases inflammation in the body.
• Take a well-rounded vitamin E. In nature, vitamin E is a complex mixture of tocopherols and tocotrienols, and tocotrienols in particular have been found to slow the build-up of plaque associated with atherosclerosis. Nuts, seeds, wheat germ, rice bran, and plant oils, especially coconut and palm oils, are good sources of vitamin E.
