The 5 Best Foods for Brain Health as You Age

  The 5 Best Foods for Brain Health as You Age Experts from around the world have a crafted a recipe that will keep your brain firing on all cylinders. It’s official: Today’s typical Western diet — laden with salt, sugar, calories and saturated fats — is as bad for our brains as it is for our bodies.That’s part of the consensus reached by the Global Council on Brain Health, as reported in a recently released paper titled “Brain Food: GCBH Recommendations on Nourishing Your Brain Health.”The council is a collaborative effort of AARP. It comprises scientists, health professionals, scholars and policy experts from around the world.

Foods that combine fats and carbs appear to send the human brain haywire, creating rewards above and beyond what And some combined fat and processed carbohydrates — chocolate chip cookies, for instance. The volunteers' brains were scanned as they decided how much to bid for reach snack.

"Surprisingly, foods containing fats and carbohydrates appear to signal their potential caloric loads to the brain via What's more, the fat - carb combo lit up neural circuits in the reward center of the brain more than a favorite food These kinds of signals seem to help regulate what and how much we eat.

Why do some of us tend to overeat certain foods even when we are not hungry? Researchers from Yale University revealed how the carbohydrate-fat combination may light up the brain's reward system. 

The study titled "Supra-Additive Effects of Combining Fat and Carbohydrate on Food Reward" was published in Cell Metabolism on June 14. Dana Small, director of the Modern Diet and Physiology Research Center at the university, was the senior author of the study. She explained how biological processes in our body carefully define values for food in order to make adaptive decisions.

Could a healthy diet prevent the brain shrinking?

  Could a healthy diet prevent the brain shrinking? New research suggests that a healthy diet rich in fruit, vegetables, fish, and healthy fats could help prevent the brain shrinking as we age, which in turn could help preserve cognitive skills. Carried out by researchers at the Erasmus University Medical Center in Rotterdam, the Netherlands, the study looked at 4,213 participants with an average age of 66, none of whom had dementia.

A new study reports foods that contain both carbs and fats evoke greater response in the brain 's reward center than foods that contain either just carbs or fats . “Surprisingly, foods containing fats and carbohydrates appear to signal their potential caloric loads to the brain via distinct mechanisms.

"For example, a mouse should not risk running into the open and exposing itself to a predator if a food provides little energy," she said.

As many as 206 adult participants were shown photos of snacks that contained mostly fat, mostly sugar, and a combination of fat and carbs. They were asked to estimate how many calories were in the food items and also reveal how much they would pay for it.

"Surprisingly, foods containing fats and carbohydrates appear to signal their potential caloric loads to the brain via distinct mechanisms. Our participants were very accurate at estimating calories from fat and very poor at estimating calories from carbohydrate," explained Small.

Participants were also willing to pay more money for the fat-carb combination foods compared to the ones containing only fat or only carbohydrates. By using real-time brain scans, the research team observed how these combination foods could light neural circuits in the reward center of the brain.

The study titled "Supra-Additive Effects of Combining Fat and Carbohydrate on Food Reward " was published in Cell Metabolism on June 14. The team fed mice a high- fat diet, tracking their leptin levels and how the mice’s brains responded. They discovered that the high- fat diet also encouraged

The response was found to be greater when compared to sweeter snacks, more energy-dense food, or even a favorite food. "Liking has nothing to do with this response. Certain foods are harder to resist," Small said.

To understand why our brain works in such a way, the authors note how our ancestors mostly ate natural sources of food and did not consume snacks combining fats and carbs.

But today, our modern menus offer options ranging from pizza to doughnuts to other processed foods. Doughnuts, invented in 1847, are estimated to contain 11 grams of fat and 17 grams of carbohydrate. Since these foods have not been around for too long, the human brain may not have evolved to handle the reaction they trigger.

"The modern food environment proffers up nutrients in doses and combinations that do not exist in nature," the authors wrote. "This contrasts sharply with our ancestors’ diet composed mostly of woody plants and raw animal meat."

FDA Bans Dangerous Trans Fats From Packaged and Restaurant Foods

  FDA Bans Dangerous Trans Fats From Packaged and Restaurant Foods Companies had until Monday to remove the unhealthy ingredient from their products. In 2015, the FDA deemed artificial trans fats unsafe because of their link to heart attacks.Companies had until June 18, 2018 to eliminate the ingredient from foods.Artificial trans fats have been used for more than 100 years - but as of Monday, our food is free of them.Trans fats have been a staple in the tastiest junk foods for more than 100 years.

The brain 's reward system evolved to make us want foods containing nutrients we need. Foods that combine fats and carbs , like donuts, trick us into thinking they have more nutrients than they do The Yale University finding sheds light on how the processed food industry cashes in on the human

These findings may help experts understand how the reward system contributes to weight gain by promoting overeating, even if the person is not hungry. Recent studies highlighted increasing rates of obesity in the United States as well as the abundance of processed food options in the workplace.

Olive Oil Could Reduce Risk of Heart Attack and Stroke .
<p>The Mediterranean diet staple olive oil could help you avoid heart attacks and stroke when combined with sleep.</p>Researchers from the Keenan Research Centre for Biomedical Science at St. Michael’s Hospital in Toronto found that levels of an important protein increase after eating foods high in unsaturated fats, like olive oil. Published in Nature Communications on Thursday, the study revealed that that protein can inhibit a key cause of bleeding and cardiovascular diseases.
