Nuts and Resveratrol Deliver a Potent Punch to Prevent Cognitive Decline and Dementia

Raw Nuts Provide Essential Fats to Prevent Cognitive Decline

Raw Nuts Provide Essential Fats to Prevent Cognitive Decline

Nuts, especially walnuts, almonds and hazelnuts, combined with the potent polyphenol resveratrol team together to improve mood and protect the aging brain to help maintain memory and cognition. Researchers reporting in the New England Journal of Medicine have found that nuts consumed over a period of years not only help with weight management issues, but also can reduce systemic inflammation to improve spirits and prevent cognitive decline.

Resveratrol has long been associated with brain health. The Journal of Pineal Research reports that resveratrol demonstrates anti-aging properties in the brain necessary for energy production and optimal brain function. Combining these two natural agents together as part of your healthy diet can improve mood, help retain memories and preserve youthful thought patterns.

Nuts Improve Mood, Slash Brain Inflammation and Prevent Cognitive Decline

Researchers determined to validate the health-promoting capacity of nuts provided test participants with a diet of walnuts, almonds and hazelnuts for a period of 12 weeks. The volunteers for this study were sex and age-matched individuals given a control diet, and compared to a group not receiving the nut mixture. All participants exhibited symptoms of metabolic syndrome, increasing risk for developing diabetes, heart disease, mood disorders and loss of cognition.

Individuals receiving the nuts had increased levels of serotonin which will help a person feel better and potentially more satisfied and less likely to suffer from depression and poor mood. Additionally, the nut control group demonstrated reduced inflammatory markers from the high polyphenol content of the nuts. This is an important finding, as individuals exhibiting the signs of metabolic syndrome experience the effects of systemic inflammation leading to accelerated brain aging and cognitive decline.

Resveratrol Positively Influences Gene Expression to Restore Mitochondria Function

Mitochondria are the tiny metabolic engines that are responsible for powering each of our trillion or so cells throughout the body. Over time, mitochondria begin to experience loss of function and cellular decline and aging of the cell begin. Mitochondrial regulation is controlled in large part by the ‘longevity’ gene known as Sirt1. Calorie restriction and potent natural nutrients such as resveratrol are known to alter expression of the Sirt1 gene. Researchers have demonstrated that resveratrol is able to restore neural mitochondria function by reviving Sirt1 gene expression, and provides “a potent anti-aging effect within the brain.”

The human brain is a highly metabolic organ, demanding 20% of the total oxygen supply for the body. As such, it is also susceptible to the effects of oxidative stress and free radical damage that cause brain inflammation and advanced signs of aging. Natural nutrients such as resveratrol (25 – 50 mg per day) that cross the blood-brain barrier and foundation monounsaturated fats supplied by most nuts (1 to 2 ounces each day) and seeds protect the brain from damage and dramatically lower the risk of memory loss and cognitive decline.

Walnuts May Hold the Key to Breast Cancer Prevention

Walnuts are High in Antioxidants that Lower Cellular Inflammation

Researchers from Marshall University in West Virginia report in the journal Nutrition and Cancer that small amounts of walnuts eaten daily can significantly lower the risk of breast cancer in women. Walnuts are a naturally great tasting source of healthy Omega-3 fats, minerals, vitamins and protein that have long been associated with good health.

Interestingly, it is not only the potent dose of Omega-3 fats that are responsible for the risk reduction, but a synergistic effect between multiple nutrients provided by the nut. Scientists now confirm that eating two ounces of this super food each day can significantly lower your risk of developing this insidious killer disease.

Regular Walnut Consumption Slows Breast Cancer Tumor Progression

The study was conducted using mice that are genetically predisposed to develop breast cancer tumors.  Lead researcher, Dr. Elaine Hardman set out to determine the effect of a typical diet and a walnut-enhanced diet through an entire lifespan. Scientists examined dietary nutrition supplied by the mother through conception and weaning and then by eating walnuts directly. Mice are frequently used for this type of research because they follow similar patterns of breast cancer carcinogenesis when compared to humans.

Dr. Hardman found that the group whose diet included walnuts from conception to late life developed breast cancer at less than half the rate of the group consuming a typical diet. In addition, the number of tumors and their sizes were significantly smaller. Of the results, she commented “These reductions are particularly important when you consider that the mice were genetically programmed to develop cancer at a high rate… we were able to reduce the risk for cancer even in the presence of a preexisting genetic mutation.”

Walnuts Provide a Perfect Blend of Essential Nutrients

Researchers noted that they were unable to determine if the cancer prevention benefits were the result of deletions or additions to the diet. Adding healthy Omega fats from walnuts displaced unhealthy fats and balanced Omega-3 to Omega-6 ratios to lower systemic inflammation and oxidized LDL cholesterol levels that result in cancer development. Other studies including walnuts have shown that there are multiple health benefits achieved from the unique blend of fats, vitamins (especially vitamin E) and minerals in the flavorful nut.

The result of this study continues to add to the wealth of scientific evidence that natural nutrients provided by an array of `super foods` significantly contribute to our health. Dr. Hardman concluded “Food is important medicine in our diet… the results of this study indicate that increased consumption of walnuts could be part of a healthy diet and reduce risk for cancer in future generations.” It`s easy to add two ounces of walnuts (about 14 halves) to your daily diet to prevent breast cancer and a host of other chronic diseases.
