Iodine deficiency is becoming incredibly common because most people aren’t getting enough in their food, and chemicals like fluoride and chlorine in the water supply can deplete it. Vegans are at increased risk for iodine deficiency because they aren’t consuming iodine foods such as shellfish, dairy, eggs, and other seafood. Here are 7 strange iodine deficiency signs to look out for. 1. Outer eyebrow thinning If the outer third of your eyebrow is thinning, you could have an iodine deficiency. 2. Hair loss Iodine is vital in ensuring that you have adequate thyroid hormones to support your hair. 3. Hoarseness This may feel like a lump in your throat due to an enlarged thyroid. 4. Enlarged tongue Indentations on the outside of the tongue signify an enlarged tongue. 5. Unexplained weight gain When your thyroid doesn’t have enough iodine, it can slow your metabolism, leading to weight gain. 6. Increased estrogen Heavy periods, excessive cramping, headaches, and weight gain in the hips all signify increased estrogen. Testosterone may also decrease in both men and women if the thyroid isn’t functioning properly. 7. Lowered IQ Thyroid function affects many parts of the brain, including the portion responsible for making decisions, problem-solving, attention, focus, creativity, and memory. Iodine is vital for properly functioning thyroid hormones, which affect every part of the body. Thyroid hormones affect the ovaries and the testicles, regulate estrogen dominance, and help mood and cognitive function. Hypothyroidism is one of the most common health problems worldwide! Selenium is also essential for the thyroid, especially for conditions like Hashimoto’s hypothyroidism. Rather than waiting for iodine deficiency symptoms, add the following iodine-rich foods to your diet to help prevent a problem: •Sea kelp/seaweed •Shellfish •Fish from the ocean •Eggs •Dairy Get a high-quality water filter to eliminate chlorine and fluoride in your drinking water!
