Researchers at the University of Adelaide in Australia have found that a high-fat diet can disrupt important receptors in the stomach that signal satiety to the brain. Satiety is the feeling of having eaten enough. Scientists have mainly studied the action of pepper (cayenne pepper) on these receptors.
Researchers from the Center for Nutrition and Gastrointestinal Diseases at the University of Adelaide in Australia have published a study on the effects of chili peppers on obesity. Australian scientists have found that a high-fat diet can disrupt important receptors in the stomach that signal satiety to the brain. In detail they studied the action of a substance, capsaicin, present in pepper (eg in the species Capsicum frutescens L.) on receptors called TRPV1 located in the stomach.
Eat chilli once a day
Scientists have observed that the stomach expands when it is full, which activates nerve signals that inform the brain that you have eaten enough (satiety). This process is activated by TRPV1 receptors, which are activated in particular by capsaicin, which is found in peppers. The inhibition of these receptors or its desensitization by fatty foods causes a delay in the onset of the feeling of satiety. The person then consumes more food, which leads to weight gain. Chilli could therefore be used in weight loss and lead to the discovery of new drugs.
Previous studies had already shown that capsaicin, which is found mainly in peppers of the genus Capsaicum, reduced the amount of food ingested. This study has the merit of showing for the first time that the feeling of satiety is stimulated by TRPV1 receptors. Researchers recommend eating chili every day if overweight or obese to help reduce the amount of food intake.
Chilli a superfood full of health benefits
In addition to including more peppers in the daily consumption to increase the feeling of satiety, the use of pepper
The therapeutic properties of chilli have been known and studied for many years. Capsaicin is the substance responsible for the particular, very pungent taste of peppers, in addition to stimulating the TRPV1 receptors. This molecule also releases endorphins in the brain, neurotransmitters that give the feeling of pleasure and satiety. In addition, peppers contain other molecules such as vitamin A, B vitamins, vitamin C, calcium, iron, antioxidants and anti-inflammatory substances. Peppers are also known to be thermogenic foods, that is, they speed up the metabolism. Consuming thermogenic foods helps burn fat.
External use also
In addition to an effect on weight loss, capsaicin has an antioxidant property twice as high as vitamin C. In addition, creams based on capsaicin are often used in case of rheumatic pains, including in aches back. This substance also promotes digestion, is expectorant and acts as a vasodilator. Pepper is clearly one of the most important medicinal plants for effective natural healing.
