A recent study has added to mounting evidence suggesting that a compound found in apples and other fruits are powerhouses when it comes to preventing dementia.
The peer-reviewed study looking at the impact of flavonoid consumption was published y Walter Willett, MD, DrPH, of Harvard University in Boston, Massachusetts in American Academy of Neurology.
“Our results are exciting because they show that making simple changes to your diet could help prevent cognitive decline,” he says.
According to his study, many flavonoid-rich foods, such as apples and pears, and others fruits and vegetables like strawberries, citrus, celery, peppers, bananas as well as red wine were significantly associated with lower odds of SCD, Subjective Cognitive Decline.
As reported on N.Neurology.org, the study followed 49,493 women from the Nurses’ Health Study (NHS) (1984-2006) and 27,842 men from the Health Professionals Follow-up Study (HPFS) (1986-2002).
Poisson regression, a generalized linear model form of regression analysis used to model count data and contingency tables, was used to evaluate the associations between dietary flavonoids and subsequent SCD.
For the NHS, long-term average dietary intake was calculated from seven repeated food frequency questionnaires (SFFQs) and SCD was assessed in 2012 and 2014. For the HPFS, average dietary intake was calculated from five repeated SFFQs, and SCD assessed in 2008 and 2012.
The results showed that a higher intake of total flavonoids was associated with lower odds of SCD.
Many flavonoid-rich foods, such as apples/pears, strawberries, citrus, celery, peppers and bananas, were significantly associated with lower odds of SCD. The writer concluded that “our findings support a benefit of higher flavonoid intakes for maintaining cognitive function in US men and women.”
Henk Griessel, a plant biologist by training and Quality Assurance Manager of South Africa-based Tru-Cape Fruit Marketing, says that the company is always looking out for verified studies that prove the healthful benefits of eating apples and pears.
“This study adds to our understanding of why eating fruit and vegetables is so important to reduce the risk of brain-related decline associated with aging,” he said. Adding flavonoids to the group of naturally occurring fruit substances that prevent the many facets of aging underpins the importance of eating more fruit to reduce the risk of dementia. And, don’t forget that red wine is also on that list of flavonoid-rich substances.”
“We already know that DHQ, a form of the antioxidant Quercetin, a plant flavonol from the flavonoid group of polyphenols, has been demonstrated to reduce the inflation-causing free radicals by binding to them.
“Simply put, human deterioration can be likened to metal rusting. We already know that enzymes in antioxidants act as a form of human rust-proofing but what this study seems to also suggest is that those same enzymes reduce and even help repair the kind of brain damage that leads to a host of diseases associated with dementia,” Griessel ends.”

MINNEAPOLIS — People who eat vegetables, fruit and whole grains may have lower rates of depression over time, according to a preliminary study released recently will be presented at the American Academy of Neurology’s 70th Annual Meeting in Los Angeles, April 21 to 27, 2018.
The study found that people whose diets adhered more closely to the Dietary Approaches to Stop Hypertension (DASH) diet were less likely to develop depression than people who did not closely follow the diet. In addition to fruit and vegetables, the DASH diet recommends fat-free or low-fat dairy products and limits foods that are high in saturated fats and sugar.
Studies have shown health benefits such as lowering high blood pressure and bad cholesterol (LDL), along with lowering body weight.
“Depression is common in older adults and more frequent in people with memory problems, vascular risk factors such as high blood pressure or high cholesterol, or people who have had a stroke,” said study author Laurel Cherian, MD, of Rush University Medical Center in Chicago and a member of the American Academy of Neurology. “Making a lifestyle change such as changing your diet is often preferred over taking medications, so we wanted to see if diet could be an effective way to reduce the risk of depression.”
For the study, 964 participants with an average age of 81 were evaluated yearly for an average of six-and-a-half years. They were monitored for symptoms of depression such as being bothered by things that usually didn’t affect them and feeling hopeless about the future. They also filled out questionnaires about how often they ate various foods, and the researchers looked at how closely the participants’ diets followed diets such as the DASH diet, Mediterranean diet and the traditional Western diet.
Participants were divided into three groups based on how closely they adhered to the diets. People in the two groups that followed the DASH diet most closely were less likely to develop depression than people in the group that did not follow the diet closely. The odds of becoming depressed over time was 11 percent lower among the top group of DASH adherers versus the lowest group.
On the other hand, the more closely people followed a Western diet—a diet that is high in saturated fats and red meats and low in fruits and vegetables—the more likely they were to develop depression. Cherian noted that the study does not prove that the DASH diet leads to a reduced risk of depression; it only shows an association.
“Future studies are now needed to confirm these results and to determine the best nutritional components of the DASH diet to prevent depression later in life and to best help people keep their brains healthy,” said Cherian.
