Although there has been some evidence that suggested chronic yeast infections or candidiasis “runs in the family”, there has never been much scientific evidence until recently.
Researchers in the Netherlands and the UK, working independently, have discovered two genetic mutations that seem to cause people to have a higher rate of fungal infection which is usually caused by Candida. The genetic mutations involve missing proteins that basically help the body’s immune system to recognize fungal cells as threats.
In people with the mutations the immune system doesn’t recognize fungal cells as foreign which allows Candida cells to grow unchecked resulting in chronic infection and even system wide infection in severe cases.
This sheds a lot of light on the causes of candidiasis as it was once believed that poor diet and antibiotics were primarily responsible for Candida overgrowth. Now we know that some people are possibly genetically prone to getting infections. This information will allow researchers to better understand how the immune system works against fungal invaders and this knowledge could lead them to the discovery of some type of vaccine.
Since some people can’t naturally fight off Candida because of their genetics, then it is extremely important for those people to follow a Candida eliminating diet if they wish to be free from chronic yeast infections. These diets can be pretty restrictive but being free from the debilitating effects of Candida will be worth it.
Further research is needed, but this certainly confirms the link between Candida, genetics and heredity.
