Nuts are useful in fighting belly fat and regulating appetite , say scientists from the University of Barcelona.
For the first time, research has found a link between nut consumption and higher serotonin levels . It is believed that the hormone reduces appetite, increases feelings of happiness and satisfaction and improves heart health.
To take advantage of the health benefits of nuts, it is necessary to eat a handful of raw and unpeeled walnuts, almonds and hazelnuts a day.
According to researchers, the discovery is important for people with metabolic syndrome , which is characterized by excess adipose tissue, high blood sugar and blood pressure.
Changes in diet and regular consumption of nuts containing healthy fats and antioxidants are helpful in combating overweight, reducing the risk of developing type 2 diabetes and heart disease, scientists say.
The study involved 22 volunteers suffering from metabolic syndrome. For 12 weeks they follow a diet rich in nuts.
It turns out that participants who eat 30 grams of mixed nuts a day have higher levels of serotonin than people who do not consume these products.
Serotonin is a neurotransmitter and helps transmit impulses from one department to another in the brain. Although it is released in the brain , where it performs its functions, about 90% of serotonin in the body is found in the digestive tract and platelets in the blood.
The study is published in the Journal of Proteome Research .
