8 Iodine-Rich Foods to Improve Thyroid Health
Iodine is an essential mineral for the proper functioning of the thyroid. Any disruption of the functioning of this gland has a negative impact on the health of the body in general. In this article, we’ll reveal some iodine-rich foods to boost your health. We also recommend that you consult with your health care provider before introducing them into your diet.
The importance of iodine for the thyroid
The thyroid gland is, according to this study carried out by the Seoul National University Bundang Hospital, responsible for storing minerals essential for the synthesis of thyroid hormones. These have the function of regulating metabolism, detoxification, and growth.
Iodine deficiency in the body often leads to the development of a condition known as hypothyroidism. This condition involves a decrease in the production of thyroid hormones.
This imbalance causes serious consequences in the body, including excessive weight gain, tiredness, and irregular menstrual periods. Fortunately, some foods contain significant amounts of iodine, and can prevent the body’s iodine levels from decreasing, as stated in this research from the University of Oslo (Norway).
Hypothyroidism can be detected with a blood test, and so it’s essential to go to the endocrinologist to explain the symptoms we’re suffering from so that they can prescribe the most appropriate treatment.
Here are the best iodine-rich foods to improve thyroid health.
According to this research conducted by the University of São Paulo (Brazil), blueberries are one of the most recommended fruits to look after our bodies, thanks to their antioxidants. It’s estimated that for every 4 ounces (113 g) of this fruit we get up to 400/mcg of iodine.
Eating them on a regular basis would support our metabolism by regulating thyroid function. It is suggested to eat them in their natural state, either in salads or smoothies.

2. Natural yogurt
Natural or organic yogurt is a probiotic that can be included in the diet. This food contains a little more than half of the iodine that the body needs daily, about 90/mcg per cup.
In addition, its cultures would support intestinal function by restoring the bacterial flora, as this study conducted by the VU University Medical Center in Amsterdam, the Netherlands, claims. However, we recommend avoiding using sugar to sweeten it.
3. Himalayan salt
Many people are trying to reduce their consumption of conventional table salt as much as possible. They are also trying to absorb enough iodine from other foods.
According to popular belief, to replace table salt, one could turn to Himalayan salt, which provides 250 mcg of iodine, which is more than 150% of the recommended daily allowance. However, as with other types of salt, it’s essential that you moderate its consumption to avoid side effects.
**There’s no scientific evidence to show that Himalayan salt is more suitable for regular consumption than other types.
omega-3 fatty acids, vitamin E, and minerals such as potassium, calcium, magnesium, and iodine
It’s low in fat and calories, and it’s also one of the best supplements to a healthy, thyroid-friendly diet. Combine it with vegetables and you have the perfect menu.
These berries are delicious, versatile, and contain essential nutrients that strengthen the body’s defenses, according to this study conducted by the University of Cordoba (Spain). Although they’re sweet, experts believe that they may be appropriate for improving thyroid health because of their significant iodine content.
One cup of strawberries contains 13 mcg of iodine, about 10% of a person’s daily requirement. Combine them with yogurt and you have the perfect mix.
We recommend not boiling them too much
Regular consumption provides the body with small amounts of iodine that can be used to stimulate thyroid function. Half a cup of this vegetable provides 3 mcg of iodine, a net 2% of the recommended daily value.
7. White beans
Beans in all varieties are a food source that can supplement the diet. However, among all our iodine-rich foods, white beans top the list of those that are good for regulating thyroid function. In addition, some research claims that white beans contain more bioavailable iron than kidney beans.
A half-cup of white beans contains up to 32 mcg of iodine and very few calories. They’re also good for digestive health because they contain fiber.

The common potato is one of the most consumed foods in the world and also a source of iodine that can be found in the plant kingdom. One potato, skin and all, provides about 60 mcg of iodine when baked.
Incorporating these foods into your diet is one of the healthiest ways to give iodine to your body, especially your thyroid.
However, we shouldn’t base our diet on these foods alone. We should include them in moderation and, if in doubt, consult a nutritionist.
