What are the risks of consuming minerals?

Overloading of minerals can be a problem. Nowadays there are many products available in the commercial market with increased levels of vitamins and minerals in them.

These products claim to cover nutritional requirements, but we need to understand that the body needs to get the required minerals from dietary sources.

Getting over dozed off minerals can hurt the body.

For example, consuming too much vitamin C can cause diarrhea, stomach cramps, and nausea.

Excessive selenium could lead to hair loss or nerve damage.

Generally, people do not overdose on minerals.

But if a person consumes fortified cereals for breakfast, consumes a mineral enriched snack in between meals and consumes mineral enriched food for dinner then minerals would have ever surpassed the DV for the day.

There should always be a check on how much to consume. Getting advice from a dietician is always recommended.

To sum up

Minerals are elements found in earth and food. These compounds are essential for life.

They keep the body healthy. The minerals are categorized based on how much the body requires.

It is important to consume minerals at recommended doses from natural dietary sources.

Supplements are suggested by doctors to treat a person with a specific health condition.

Consuming more minerals does more harm than good therefore the intake of minerals should be restricted based on the daily intake value.
