That's according to a recent Australian study published in the Journal of Experimental Medicine, which reported that human genes actually remember a "sugar hit" for weeks. Not only that, but according to the researchers, chronically poor eating habits were shown to permanently alter a person's DNA.
The aim of the study was to examine the impact of diet on human heart tissue and mice. Results: A "one-off sugar hit" affected cells by switching off genetic controls, for up to 2 weeks, that are designed to protect the body against diabetes and disease.
The lead researcher, Sam El-Osta, from the Baker IDI Heart and Diabetes Institute, told the Australian Associated Press that these harmful genetic changes or mutations could linger in the cells, perhaps having the capability of altering natural metabolic responses to diet. He also stated that chronic "poor eating would amplify the effect, with genetic damage lasting months or years, potentially passing through bloodlines ... to one's children."
What are some possible take-aways from this kind of nutritional genomics research?
- Nutritional Genomics is an exciting new field that I believe will become a household name over the next few years. It involves genetic mapping to see who might be at risk for certain diseases such as high cholesterol. Perhaps this field could provide a new way to treat weight issues.
- Such a test, for example, might tell you that you're genetically programmed to fail at weight loss, a helpful tool that would let you and you your doctor to perhaps try a different strategy for losing weight.
What do you think dear readers? Would you want to know if you have "unfriendly" weight genes? I'd love to hear from you.
