This Canadian study out of Alberta looked to identify what components of the diet or nutritional supplements reduce (or increase) the risk of endometrial cancer (EC).
The results revealed, overall, there was little evidence for any association between EC and the majority of macronutrients and micronutrients examined.
However, a few things did show up. The researchers observed a statistically significant increased risk in those that consumed the highest amount of dietary cholesterol (in comparison to those who consumed the least). The researchers also observed increased EC risk at low intakes of dietary soluble fibre, vitamin C, thiamin, vitamin B6 and lutein/zeaxanthin.
On the flipside, those who consumed the most calcium from both foods and supplements had about a 28% lower risk of EC than those who consume the least.
The authors conclude, "the results of our study suggest a positive association between dietary cholesterol and EC risk and an inverse association with calcium intake from food sources and from food plus supplements."
Just remember though... if you're taking calcium supplements, I consider it mandatory that you also take a vitamin K2 supplement. Here are a few posts from the past that discuss why...
- how K2 can help prevent the increased risk of heart attacks and strokes from calcium supplements
- how K2 can help reduce the risk of kidney stones from supplemental calcium
- a more detailed discussion on why vitamin K helps put calcium to good use using warfarin to illustrate the point
