Nutritional guidelines recommend 20 to 30 grams of nuts daily

Health experts and nutritional guidelines suggest a daily consumption limit for nuts to balance their health benefits with their high energy density. Dr. Marie-Christine Boutron Ruault, a hepatogastroenterologist, recommends a daily portion of approximately 20 to 30 grams, which is roughly equivalent to a small handful.

To visualize this amount, the Fondation Louis Bonduelle notes that 30 grams is about 10 to 15 almonds or 3 to 4 walnuts. While nuts provide essential minerals such as zinc, copper, selenium, and calcium, exceeding these portions without adjusting other food intake may lead to gradual weight gain due to their concentrated caloric content.

Public health resources, including MangerBouger.fr and the Assurance Maladie, also advise consuming a daily handful of nuts that are unsalted, unsweetened, and free of chocolate.
