Fat

If you’re getting insufficient fat and cholesterol, you could be exacerbating hormonal imbalance, which includes thyroid hormones. Natural fats, which are good for health, include olive oil, ghee, avocados, flax seeds, fish, nuts and nut butters, hormone and antibiotic free full fat cheese, yogurt, and cottage cheese and coconut milk products.
Take more protein

Protein can help normalize thyroid function sine it transports thyroid hormone to all your tissues. Nuts and nut butters, quinoa, organic, grass-fed meats, eggs, and sustainably-farmed fish and legumes are good sources of protein.
Nutrient-up

Deficiency of vitamin D, iron, omega-3 fatty acids, selenium, zinc, copper, vitamin A, the B vitamins, and iodine may aggravate the symptoms of hypothyroidism. Being up to the mark on nutritional levels can help a lot with hypothyroidism.
Less Caffeine and Sugar

Reduce or eliminate caffeine and sugar, including refined carbohydrates like flour, which the body treats like sugar. Eat non-starchy vegetables, rather than grain-based carbohydrates.
Gut check

A whopping 20 percent of thyroid function depends on a sufficient supply of healthy gut bacteria, so it’s best to supplement with probiotics.
Go gluten-free

The molecular composition of thyroid tissue is almost identical to that of gluten. Eating gluten can increase the autoimmune attack on your thyroid.
Glutathione

Glutathione is a powerful antioxidant that strengthens the immune system. It can boost your body’s ability to modulate and regulate the immune system, dampen autoimmune flare-ups, and protect and heal thyroid tissue.
Avoid alcohol

Alcohol depletes you of minerals and dehydrates you. It also impairs your judgment, causes you to crave unhealthy foods and is generally high in calories.
Get active

Low-impact exercise is easy on the joints and improves your general health. In addition to the calories burned, exercise also helps you lose weight by increasing your insulin sensitivity, ensuring that the carbs you eat are used for energy instead of stored as ugly fat. Exercise really helps with hypothyroidism.
Eat small meals, more often

You want to avoid having huge spikes in your blood sugar levels since hypothyroidism has been linked to insulin resistance. Instead of having three huge meals, you want to be eating smaller meals, more often. This keeps your blood sugar levels stable, while providing your body with a constant stream of nutrients.
