Milk and dairy products are the main source of iodine in many diets, and an important iodine source in many countries. However, our latest research found that the iodine concentration of most alternatives to cows’ milk – such as soy and almond “milk” – is very low. This matters because deficiency of iodine, especially during pregnancy, affects brain development and is linked to lower intelligence.

Heavy metals are natural components of the earth’s crust; however, certain activities of mankind, such as mining and smelting, have led to them becoming concentrated in the environment, in some areas reaching potentially harmful levels. Other sources such as vehicle emissions, industrial waste and fertilizers also contribute to the accumulation of heavy metals in the soil, atmosphere and surface water.

Heavy metals can be severely detrimental to the human body, having toxic and carcinogenic effects and causing the oxidative deterioration of biological macromolecules. The various metals have been implicated in the development of many diseases, including Alzheimer’s disease, diabetes and several forms of cancer.
