Iodine is crucial for our health. It's necessary for hormone function and a range of other processes, including metabolism and oxygen consumption. Some of the most noticeable symptoms of iodine deficiency are drowsiness, weakness, constant coldness, low mood, depression, and in extreme cases, heart problems. Iodine deficiency is directly linked to higher cholesterol, and fat pads begin to form in the body, causing weight gain despite your diets and regular physical activity.

Iodine deficiency means that your thyroid isn't functioning properly, hormone levels drop, and the body switches to what's called the "slow mode." This is often referred to as "gaining weight just by looking at food." Of course, iodine should be taken care of even if you're not trying to lose weight.

Iodine is found most abundantly in sea vegetables, seaweed, fish, fish oil, and seafood. It is also present in mineral waters and, of course, fortified salt. However, iodine evaporates during cooking (use it only raw).

And finally, the most important part: did you know that iodine also has many enemies?

Several types of vegetables reduce iodine absorption, thus decreasing the effectiveness of other minerals by 30 to 70%! Avoid cabbage, cauliflower, Brussels sprouts, legumes, and soy products. It's true that cooked vegetables lose a third of their power (and the negative effects as well), but still. When you're dieting, try to avoid these foods or at least limit them.
