Which is better, high fructose corn syrup or sugar? The Good Human provides a good breakdown of the difference.
Essentially, high fructose corn syrup (hfcs) is a manufactured product. Several corn syrups undergo a process to increase their fructose. It’s a lot less expensive than sugar, and lasts longer.
In soda, it has been found that by using HFCS instead of pure sugar it can make the soda 10 times richer in harmful carbonyl compounds. According to one study, carbonyl compounds are elevated in people with diabetes and are blamed for causing diabetic complications such as foot ulcers and eye and nerve damage.
Sugar is a natural product, derived from cane sugar. It is fresher, hence the shorter shelf life. It has not been altered to the extent of HFCS. Sugar is also processed differently by our bodies. It’s not necessarily better, because it stimulates the liver to release more fat into the bloodstream.
So what’s the answer? It would be best to avoid both hfcs and sugar whenever possible. I prefer a natural product, so I avoid HFCS as much as I can in favor of sugar.
