Examples include porridge oats, wholewheat pasta and brown rice. ## Just 48g daily shows benefits Consuming roughly two large slices of brown bread or a bowl of oats per day was enough to improve heart health markers. ## Four slices bring biggest gains The greatest improvements occurred at 60g to 100g daily, about four large slices. This level brought the biggest cuts to blood pressure and cholesterol. ## Weight loss of half a pound Participants consuming 48g of whole grains daily lost an average of 0.2kg, or roughly half a pound, though timing varied across studies. ## Waist size shrank measurably Waist circumference reduced by 0.22 centimeters at the 48g level. Less visceral fat around organs means lower disease risk. ## Total cholesterol dropped Cholesterol levels fell by 0.10 mmol/L at 48g daily. The NHS recommends Britons aim for a total cholesterol level of 5mmol/L. ## Bad cholesterol fell significantly Low-density lipoprotein, the so-called bad cholesterol, dropped by 0.07 mmol/L. This type causes fatty deposits that block arteries. ## Harmful blood fats decreased Triglycerides, a blood fat that drives heart disease when high, fell by 0.04 mmol/L. Healthy readings should be below 1.7mmol/L. ## Blood pressure improved Systolic blood pressure, the top number measuring pressure when the heart beats, dropped by 0.82 millimeters of mercury. ## Higher intake tripled blood pressure benefits At 60g to 100g daily, the reduction in blood pressure was three times greater than at the lower 48g level. ## Cholesterol cuts doubled at higher intake Total cholesterol dropped by 0.21 mmol/L at 60g to 100g daily, while LDL cholesterol fell by 0.16 mmol/L and triglycerides by 0.08 mmol/L. ## Why whole grains work They retain key nutrients like fiber, B vitamins, iron, zinc, magnesium, healthy fats and plant compounds called phytonutrients. ## Study didn't measure heart attacks directly Researchers didn't track cardiovascular events like heart attacks and strokes, so longer studies are needed to confirm direct risk reduction. ## A simple, affordable dietary change Lead researcher Dr. Helda Tutunchi says increasing wholegrain intake is an accessible strategy that can complement other lifestyle interventions. > Increasing wholegrain intake is a relatively simple, accessible and affordable dietary strategy that can complement other lifestyle and medical interventions. ## Key takeaway Eating 48g to 100g of whole grains daily (two to four slices of wholegrain bread) can significantly improve heart health markers.
