A meta-analysis of walnuts by Harvard scientists has found diets rich in walnuts can significantly reduce cholesterol levels, supporting growing evidence to suggest these popular nuts can improve healthy blood lipid ratios.
In their investigation of thirteen studies, the researchers demonstrated that walnut-rich consumption decreased total and low-density lipoprotein (LDL) cholesterol during short term trials.
However the scientists suggested that "larger and longer-term trials" are needed to observe the effects of eating walnuts, rich in polyunsaturated fatty acids, on cardiovascular risk and weight management.
Their analysis joins a blossoming body of science that has linked nut consumption – including almonds and macadamias – to improvements in markers of cardiovascular health.
Coronary heart disease places a significant financial burden on all European states, and in the UK alone costs the health system more than €5bn per year. Governments, scientists and the food industry itself continue to invest time and money in pinpointing potential dietary solutions that could boost cardiovascular health.Read the full article here.
