There is no one best diet for hypothyroidism, a condition in which the thyroid gland produces less of its hormones than the body needs. However, a healthy diet that includes whole, nutrient-dense foods like vegetables, fruits, nuts, and fish can help manage the condition. While seafood is a good source of iodine, which is required for thyroid hormone production, there is controversy over whether it is suitable for people with thyroid conditions due to varying iodine content and the presence of toxins like methylmercury. Tuna, for instance, is a type of fish that is generally considered safe and healthy, but it also contains higher levels of iodine and mercury than other types of fish. Thus, it is important to understand how a tunafish sandwich fits into a diet for someone with hypothyroidism.

Selenium-rich foods like tuna and Brazil nuts may support thyroid function
While there is no one "best" diet for hypothyroidism, eating certain foods can make a difference in how well your medications work. Selenium-rich foods like tuna and Brazil nuts may support thyroid function.
Selenium is a trace element, or nutrient, that the body needs to stay healthy. It acts as an antioxidant by protecting the body from free radicals, which are unstable cells that can increase the risk of diseases, including cancer. Selenium also plays a role in reproduction, thyroid function, cognition, DNA and muscle repair, and immune health.
Brazil nuts are one of the most selenium-rich foods, with just a few nuts providing more than the recommended daily intake. Other selenium-rich foods include eggs, lean meats, poultry, fish, and whole grains such as brown rice and wholemeal bread. Enriched refined grains, such as white bread and pasta, are also fortified with selenium and other minerals.
Tuna is another excellent source of selenium. A 3-oz serving of cooked yellowfin tuna contains 92 mcg of selenium, or 167% of the adult daily value (DV). This makes it an even better source of selenium than halibut (47 mcg per 3 oz), sardines (45 mcg per 3 oz), ham (42 mcg per 3 oz), shrimp (40 mcg per 3 oz), and chicken (22 mcg per 3 oz).
Incorporating selenium-rich foods like tuna and Brazil nuts into your diet may help support thyroid function if you have hypothyroidism. However, it's important to note that everyone's dietary needs are different, and hypothyroidism is typically managed with medication. If you're unsure about how much selenium you should consume, speak with a healthcare professional.

The Mediterranean diet is recommended for hypothyroidism
While there is no one "best" diet for hypothyroidism, the Mediterranean diet is recommended for people with this condition. This is because it is a healthy diet that can make you feel your best and keep you healthy. The Mediterranean diet is recognised as a cultural heritage by UNESCO and is mostly plant-based, including a high consumption of whole grains, fruits, and vegetables, with a moderate consumption of alcohol during meals. This provides a small amount of saturated fatty acids and a high quantity of antioxidants and fibre.
The Mediterranean diet is beneficial for people with hypothyroidism because it emphasises plenty of fruits and vegetables, lean proteins, and whole grains. These foods are rich in nutrients like iodine, selenium, zinc, vitamin D, vitamin B12, magnesium, and iron, which may be beneficial for hypothyroidism. For example, iodine is needed to make thyroid hormones, and selenium supports thyroid hormone production and protects the thyroid from damage caused by oxidative stress.
In addition to the Mediterranean diet, people with hypothyroidism can benefit from incorporating the following nutritious foods into their diet: fruits, non-starchy vegetables, starchy vegetables, lean fish, eggs, meat, and poultry. It is also recommended to limit inflammatory foods, added sugar, and ultra-processed foods.
It is important to note that medication is the first line of treatment for hypothyroidism, and dietary changes can help reduce symptoms and support overall health. Additionally, individual calorie needs and dietary requirements may vary, so it is always best to consult with a healthcare professional before making any significant dietary changes.

Iodine in seafood can be beneficial, but some people with thyroid issues may not do well with it
While there is no one "best" diet for hypothyroidism, eating nutrient-rich meals can make a difference in how well thyroid medications work. A healthy diet for people with hypothyroidism includes whole, nutrient-dense foods like vegetables, fruits, nuts, and fish. Seafood, including tuna, is a good source of lean protein and is recommended as part of a hypothyroidism diet.
However, there is some controversy over whether people with thyroid and autoimmune thyroid conditions should consume seafood due to its iodine content. Iodine is required for the formation of thyroid hormones, and an iodine deficiency may lead to decreased thyroid hormone production. While seafood does contain iodine, in most cases, the iodine content is not high enough to cause problems for people with thyroid conditions.
That being said, not everyone with thyroid conditions does well with iodine. Tuna, salmon, and sardines have higher levels of iodine relative to the recommended daily intake (RDI). For most fish, iodine content typically ranges from 25 to 140 micrograms per 4-ounce serving. It's important to note that larger fish tend to have higher amounts of mercury and other toxins, such as methylmercury, dioxins, polychlorinated biphenyls, polybrominated diphenyl ethers, and chlorinated pesticides.
Therefore, while iodine in seafood can be beneficial for thyroid health, some people with thyroid issues may need to monitor their iodine intake and choose seafood options with lower iodine levels. It is always advisable to consult with a healthcare professional or dietician to determine the best dietary approach for managing hypothyroidism, as individual needs may vary.

Canned light tuna is a low-mercury fish option
While there is no one "best" diet for hypothyroidism, eating certain foods can make a difference in how well thyroid medications work. People with hypothyroidism can benefit from a diet rich in whole, nutrient-dense foods like vegetables, fruits, nuts, and lean fish. Selenium and zinc, for example, may improve thyroid function. Tuna is a selenium-rich food that is also high in iodine, which may affect iodine therapy.
There is some controversy over whether people with thyroid and autoimmune thyroid conditions should consume seafood. While seafood has many health benefits, there are some potential risks. Some people are concerned about the iodine present in seafood, but in most cases, the iodine content isn't high enough to cause problems.
Tuna, especially canned light tuna, is a low-mercury fish option. According to the Environmental Protection Agency, larger fish tend to have higher amounts of mercury and other toxins. Fish with high levels of mercury include shark, swordfish, king mackerel, and tilefish, which should be avoided. In contrast, canned light tuna, salmon, pollock, and catfish have lower levels of mercury and are safer options.
In conclusion, canned light tuna is a nutritious and low-mercury fish option that can be included in a hypothyroidism diet. However, it is important to remember that individual dietary needs may vary, and it is always advisable to consult with a healthcare professional before making significant dietary changes.
