Foods High In Zinc
Minerals, such as Zinc, that are important to help our bodies function, are found everywhere!
They’re found in inorganic substances found in rock and soil as well as being found in living tissue and plants.
As humans, we need minerals for proper composition of bones and blood to help us maintain cell function.
We obtain our minerals mainly from plant sources, so understanding the importance of soil nutrients and quality is really important because it gives us a better understanding of which minerals we might be missing out on and why.
Equally, we need to understand how some dietary restrictions can also cause mineral deficiency.
This is because certain minerals, such as Zinc, can also be found in meats, seafood and shellfish. Zinc deficiency may be found in people who avoid seafood (and in particular shellfish) but who are also not great vegetable eaters as well.
Heavily processed foods are also very low in zinc, as most of the mineral is removed during processing.
Over cooking foods may get rid of much of the zinc especially in vegetables (which is why homemade vege stock should be staple!).
In New Zealand you may often hear about our soil being “depleted” of nutrients. There are a few explanations to this statement.
Although New Zealand soil is varied throughout the country, most mineral content comes from volcanic rock bed which contains some minerals, but not all.
Heavy rain or flooding can also wash away important minerals, zinc being one of them.
Lack of vegetation growth can also result in a lack of minerals because the soil needs decomposing vegetation for further mineral repletion.
In New Zealand our soil is regarded as varied and “rich” but only a small percentage is actually regarded as fertile enough to grow food without too much interference.
Most of our agriculture relies on heavy fertilisation which actually further depletes the soil of important nutrients including minerals such as selenium and zinc, among others.
