As a health and nutrition expert with years of experience in the field, I have often been asked about the safety of various substances, including glycerin. Glycerin, also known as glycerol or propane-1,2,3-triol, is a clear, colorless, odorless liquid that is widely used in the food and pharmaceutical industries. It is a byproduct of soap making and can also be produced from synthetic sources.

Is it safe to drink glycerin? The answer to this question is not straightforward and depends on several factors, including the amount consumed, individual tolerance, and the context in which it is used.

Firstly, glycerin is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) when used in accordance with good manufacturing practice. This means that in small quantities, as an ingredient in food products, glycerin is considered safe for consumption. The small amount of vegetable glycerin used in food products isn't likely to cause side effects.

However, it is important to note that glycerin is classified as a sugar alcohol. Sugar alcohols can have a laxative effect when consumed in large amounts. This is because they are not fully absorbed by the body and can draw water into the intestines, leading to an increase in stool bulk and potentially causing diarrhea. Consuming a large amount of glycerin could therefore potentially lead to gastrointestinal discomfort and diarrhea.

Additionally, the osmotic effect of glycerin in the intestines can lead to increased urination as the body attempts to eliminate the excess substance. This could potentially lead to dehydration if fluid intake is not adequately maintained.

It is also worth mentioning that glycerin has a high caloric content, with approximately 4.3 calories per gram. Consuming large amounts of glycerin could contribute to weight gain if not balanced with an appropriate diet and physical activity.

In conclusion, while glycerin is generally safe for consumption in small amounts as part of a balanced diet, it is not advisable to consume it in large quantities or as a sole source of nutrition. It is always best to consult with a healthcare professional or a registered dietitian before making significant changes to your diet, especially when considering the consumption of substances like glycerin.

The small amount of vegetable glycerin used in food products isn't likely to cause side effects. It is classified as a sugar alcohol, though, and in turn can have a laxative effect when consumed in large amounts. Thus, it may cause diarrhea, excessive urination and dehydration if you eat a lot of it.Oct 3, 2017read more >>
