Diet modifications (including more wine and cheese) May Help Reduce Cognitive Decline

Participants also answered questions about their food and alcohol consumption at baseline and through two follow-up assessments. The Food Frequency Questionnaire asked participants about their intake of fresh fruit, dried fruit, raw vegetables and salad, cooked vegetables, oily fish, lean fish, processed meat, poultry, beef, lamb, pork, cheese, bread, cereal, tea and coffee, beer and cider, red wine, white wine and Champaign and liquor.

Here are four of the most significant findings from the study:

Cheese, by far, was shown to be the most protective food against age-related cognitive problems, even late into life;

The daily consumption of alcohol, particularly red wine, was related to improvements in cognitive function;

Weekly consumption of lamb, but not other red meats, was shown to improve long-term cognitive prowess; and

Excessive consumption of salt is bad, but only individuals already at risk for Alzheimer’s Disease may need to watch their intake to avoid cognitive problems over time.

Finally some good news.

Visceral fat delivers signal to the brain that hurts cognition

“We have identified a specific signal that is generated in visceral fat, released into the blood that gets through the blood brain barrier and into the brain where it activates microglia and impairs cognition.”

Molecule found in oranges could reduce obesity and prevent heart disease and diabetes

In mice, so don’t start gorging on oranges.

Sorry, sarcasm restriction didn’t last long.

Early studies on the diet suggested red wine was a major contributor to the health benefits of the Mediterranean diet because it contains a compound called resveratrol, which activated a certain pathway in cells known to increase lifespan and prevent aging-related diseases. However, work in Mashek’s lab suggests that it is the fat in olive oil, another component of the Mediterranean diet, that is actually activating this pathway.

Olive oil in the diet may also help mitigate aging-related diseases
