Zinc

Zinc is an essential mineral that plays a crucial role in various bodily functions, including immune system regulation, wound healing, and olfactory and taste nerve function. Adequate zinc intake is a basic defense mechanism against inflammation and infection, and zinc-rich foods are recommended as a part of a well-balanced diet 2.

Research has shown that zinc increases the metabolic rate, tending to prevent obesity 5. Additionally, zinc is involved in the enzyme reaction that helps retain carbon dioxide, which is important for overall health and resistance to disease 4.

Zinc deficiency can lead to impaired immune function, making individuals more susceptible to infections. Supplementing with vitamin A, which is also essential for immune function, has been shown to reduce a wide range of diseases 2. A well-balanced diet that includes zinc-rich foods, along with adequate vitamin A, can help increase overall health and resistance to disease 2.

In the context of COVID-19, zinc has been suggested as a potential treatment for long-haulers who experience loss of smell (anosmia) 2. Calcium channel blockers, which increase carbon dioxide retention ability, have also shown benefits in treating COVID patients 4.

It is worth noting that the importance of zinc in the body has been recognized for some time, with research dating back to the 1970s 7. However, the exact mechanisms by which zinc exerts its effects are still not fully understood, and further research is needed to fully elucidate its role in human health 7.

In terms of specific dietary recommendations, Ray Peat has suggested that naturally fermented sourdough bread is less harmful than standard or unleavened wheat products, and that a diet rich in zinc and other essential nutrients can help prevent a range of diseases 5.
