Perhaps one of the more pleasurable studies to take part in (provided you like a nice sweet strawberry), a team of volunteers were tasked with eating half a kilogram of strawberries a day for a month in order to see if it effects blood parameters in any way. Researchers found that their levels of bad cholesterol and triglycerides were significantly reduced. The antioxidant properties of strawberries is relatively well documented, meaning the risk of heart disease may be reduced, but this new finding was relatively unexpected.
The researchers acknowledge that they cannot pin point what compounds exactly caused this, but they suggest that it is probably the anthocyanins, the vegetable pigment responsible for their vibrant red colour. However there is no mention of limitations such as what the subjects consumed habitually during the investigation, it may be that they all ate high levels of soluble fibre helping to lower cholesterol too. Either way the findings are interesting, but I personally recommend you go out and eat 500g of strawberries everyday, 4-5 individual strawberries would absolutely suffice.
