Are you getting enough heavy metal?!

I was intrigued after watching Superfoods on C4 the other night. The presenter Kate Quilton discussed the scientific research around lack of Zinc in our bodies and the increased experiencing of anxious and depressive symptoms.

I looked into this further and found that Zinc has many uses in our bodies and is essential in our growth, development, our brain and our immune function.

There are many studies now which have found similar results, stating that taking a Zinc supplement may help improve your anxious symptoms.

Zinc is one of the most important trace elements in the body, and helps promotes growth in many of our essential bodily functions including the regeneration of the liver. Sounds good to me!

Now I’m not one who would normally recommend supplements as I try to eat a balanced and healthy diet, however, we have no storage system for Zinc in our bodies so if you don’t eat the right food which contain Zinc on a regular basis then you don’t have it in your body, simple as.

Zinc is usually found in meat, chicken and famously in oysters, it is the Zinc that provides the aphrodisiac effect! It is also found in beans and peas, soy products and nuts.

It is recommended that we take between 25mg – 50mg every couple of days to keep our absorption up. But, you know what, after completing this research and watching the Superfoods programme on Channel 4 the other night, I’m going to give it a try and I will report back to you on my progress. I’ll keep a diary of how I am feeling/ acting/ behaving and I’ll report back when anything significant happens. If not, I’ll report back in one month. We shall see...
