Rich in tryptophan and B vitamins, pasta could prove to be a wise choice for those suffering from seasonal affective disorder. In fact, pasta is an excellent ally for several reasons: it relaxes, induces sleep and does not make you fat, if it is eaten in the right amount and with the right seasonings. Its consumption also promotes the synthesis of insulin which, in turn, facilitates the absorption of melatonin, which ensures good quality sleep, with a consequent reduction in the production of hunger hormones. Slow and relaxed chewing also promotes a perception of fullness, which leads to less food being eaten. Finally, it is an important source of complex carbohydrates as well as glucose, which is the basic fuel for the brain and muscles.
