New research from the University of Cambridge shows strong links between vitamin C levels and the risk of stroke. This study measured vitamin C levels in blood samples taken from over 20,000 people over nine years. Results showed that those with the highest levels had a 42 per cent lower risk of stroke compared to those with the lowest. This doesn’t mean you should take supplements – vitamin C in found in abundance in fresh fruit and vegetables.
Vitamins and Minerals
Brazil nuts are a rich source of selenium but until now no studies have investigated how available this mineral is for us to use (bioavailability). Researchers from the University of Otago in Dunedin in New Zealand found that consuming just two Brazil nuts a day for 12 weeks increased the amount of selenium in the blood by over 60 per cent. The authors of this study concluded that including Brazil nuts in the diet could avoid the need for supplements.
New research suggests that vitamin C may reduce some of the health problems associated with diabetes. Vitamin C is an antioxidant – one of the ‘good guys’ that goes around the body mopping up damaging molecules called free radicals. Diabetics produce more free radicals which is why they are more susceptible to tissue damage leading to amputations, heart disease and blindness. The authors stress that they would not encourage people to start taking vitamin C supplements.

The number of people who make it past the 100-years-old mark (centenarians) is increasing.
Researchers from the Netherlands have shown that supplementing the diet with folic acid can help boost brain power in the over-50s. In this three-year study, those taking 800 micrograms of folic acid per day performed significantly better in a range of mental agility tests than those taking a placebo.
