Michael discovers incorporating wholegrains into our diet, is a tasty swap that could really benefit our health. Wholegrains such as wholegrain pasta, bread and brown rice contain more fibre, vitamins and minerals, than refined grains. This simple swap can help reduce blood pressure, improve heart health and boost the gut microbiome. Michael talks to Dr Caleigh Sawicki, from the Brigham and Women’s hospital and Harvard Medical School, whose research suggests that the fibre consumption of wholegrains can keep us fuller for longer and this slow digestion could result in a lower increase in blood sugar.
