WATSONVILLE, Calif. — According to new published research in the Journal of Nutrition, consumption of anthocyanin-rich foods such as strawberries may play an important role in lowering cholesterol and other risk factors for cardiovascular disease.
To evaluate the effects of strawberries on cardiovascular risk factors, researchers at Oklahoma State University conducted a 12-week study with a group of 60 overweight adults. Participants were randomly selected to consume a high (equivalent to 500 g fresh strawberries) or low (equivalent to 250 g fresh strawberries) daily dose of a beverage made with freeze-dried strawberries, or a control beverage.
The study revealed the high dose strawberry supplements were effective in significantly reducing total and LDL cholesterol levels. Additionally, both the low and high dose supplements were equally effective in decreasing lipid peroxidation compared with the control groups.
“With more than two-thirds of U.S. adults being overweight or obese, and having metabolic abnormalities associated with increased cardiovascular risk factors, we are pleased to see the positive effects that strawberries can have on lowering serum cholesterol,” said lead researcher Arpita Basu, Ph.D., RD, associate professor of nutritional sciences, College of Human Sciences at Oklahoma State University.
As the first 12-week study to report the total and LDL cholesterol-lowering effects of a higher amount of strawberries in obese adults, the researchers suggest that a strawberry-supplemented diet may be of clinical significance as a nutritional strategy to help reduce cardiovascular disease risk.
About the California Strawberry Commission
The California Strawberry Commission, www.californiastrawberries.com, is a state government agency representing all of California’s strawberry farmers, shippers and processors. With an emphasis on food safety education, commission activities focus on production and nutrition research, trade relations, public policy, marketing and communications. California produces more than 85 percent of all strawberries grown in the United States.
There has long been research — both anecdotal and data-based — suggesting a positive link between the eating of fruits and vegetables and healthy outcomes, including disease prevention.
The National Mango Board is working to pursue the connection, specifically with mangos, and has some research on its side. The board is publicizing early results of some studies and refining the nutrition message as it promotes mango and green papaya salad.
New mango nutrition research on obesity and cancer are the subjects recently presented at the Federation of American Societies for Experimental Biology in Boston. The research identifies important findings that merit further investigation to determine whether mangos can potentially have a positive effect on blood sugar in obese individuals and help to limit inflammation.
An Oklahoma State University study examined the effects of daily mango consumption on the obese. Twenty adults participated in the study, consuming significant amounts of mangos in a dried form for 12 weeks. Blood sugar levels at the conclusion of the study were significantly lower than the baseline in both male and female subjects, but there were no significant changes in body composition for either gender.
Texas A&M had another study on the effects of polyphenols found in fresh mangos on cancerous and non-cancerous breast cells, which were examined. This study suggests that mango polyphenols might limit inflammatory response in both cancerous and non-cancerous breast cells. Because this was an in vitro study, more research is needed to determine whether mango polyphenols can have the same effect in humans.
The National Mango Board is actively marketing the nutrition message, which claims that mangos are a nutrient-rich fruit containing more than 20 different vitamins and minerals. The NMB states that mangos are an excellent source of the antioxidant vitamins C and A. Vitamin C is important for wound healing and immune function; and vitamin A is critical for vision and helps maintain healthy skin.
