To stabilize thyroid activity, you have to give her all the essential nutrients she needs. Supplied in insufficient quantity, they constitute an obstacle to the proper manufacture of thyroid hormones, essential to the regulation of our metabolism.

Algae, an effective boost

" The thyroid can not make hormones without iodine . And our only source of iodine is food, "says Dr. Pierre Nys, endocrinologist. The average recommended intake of iodine for an adult is 150 μg per day, a threshold reached by few of us.

Although table salt is usually enriched, consuming it regularly does not help to achieve this goal. And better not to force the salt shaker to avoid hypertension.

Iodine is found in fish and seafood, but seaweed has more of it: about 4500 μg / 100 g, which is 20 times more than salmon! Sprinkle your veggies and vegetables with kombu, wakame or nori . "There is no risk of excess unless you have severe hyperthyroidism," says Dr. Nys.

Egg yolk, an outstanding ally

Selenium is a major antioxidant without which the thyroid can not function at full speed. Several studies have indeed shown that a selenium deficiency quickly dry up its production of hormones.

Wholegrain cereals and Brazil nuts also contain some, but their content varies according to the soil on which they were grown. It is therefore better to rely on animal products in which the selenium content is almost constant, such as meat, fish and shellfish.

However, egg yolk is one of the best sources of choice because it also delivers zinc, useful for boosting lazy thyroid glands.

Fermented foods, a valuable weapon

"20% of thyroid function depends on a sufficient amount of healthy bacteria in the intestines," said Dr. Philippe Veroli, author of Thyroid, natural solutions (eds Thierry Souccar).

An unbalanced digestive flora gives rise to a silent inflammation that gradually decreases the tone of the thyroid. Better to pamper its microbiota gorging itself with natural probiotics. Fermented foods (kefir, miso, tempeh ...) abound. Put them at least once a week on the menu.

Coconut oil, a smart substitute for butter

All "vegetable oils provide essential fatty acids that protect against depression and anxiety generated by thyroid dysfunction," says Dr. Pierre Nys.

But that of coconut is preferred because it is full of specific fatty acids - medium chain - which stimulate the thyroid gland. You can use it in seasoning or for cooking, because it supports the rise in temperature.
