Monosodium glutomate (MSG) is a chemical flavor enhancer is found in Chinese food, fast food, and many processed foods such as potato chips.

Studies show that MSG acts as an excitotoxin; a class of chemicals that overstimulate neuron receptors. This works to destroy nerve cells to slow cognitive function and causing hormonal imbalances.

No direct clinical evidence shows MSG to be harmful to fertility. But, MSG stimulates your pancreas to produce more insulin, which causes other hormones to be thrown out of balance. In addition, a North Eastern Illinois University study showed that male rats treated with MSG had a decreased conception rate.

The FDA has classified MSG as a food ingredient that’s “generally recognized as safe,” but its use remains controversial, so we suggest watching what exactly you are consuming to better your health.
