Walnuts have been described as a source of protein and so they are but scientists have to say something more about them. According to a recent study conducted by the scientists incidentallyallocated ten hospitalized obese patients. They instructed them to have five undeviating days of either a smoothie with 48 grams of walnuts or anidentically tasting and textured smoothie without walnuts.
Then after a month of going back to their indigenous diet, those who first received the walnut smoothie then got five days of the non-walnut smoothie and vice versa. At the start of the study the researchers calculated the brain activity of each of the study subjects with a functional magnetic resonance imaging (fMRI) machine. After the 5 day smoothie diet the subjects went through another fMRI to observe the direction of the things to come.
Again the researchers displayed different pictures of food while undergoing the fMRI. Pictures incorporated images of highly worthwhile foods like (high-calorie or high-fat images, e.g., cakes, onion rings), “less desirable foods” (low-calorie or low-fat images, for example vegetables and fruits) and “non-foods” (e.g., flowers, rocks, trees).Before and after each fMRI scan, study subjects completed visual analog scales (VAS) to measure how hungry or full they felt.
This study resulted in two major findings; firstly with the walnut smoothie diet revealed feeling less hungry thanthe non-walnut smoothie diet. Secondly after the five days of walnut smoothies, study subjects had variances in their brain activity (as measured by fMRI) when shown food. Especially, the right insula part of the brain seemed to be more agile. Some parts of Insula were answerable for satiety and inhibition. In other words the walnuts may be responsible for brain to cool down when shown mouth-watering food. Therefore, walnuts may aid in controlling your hunger and thus help with managing your weight.
