Consuming wholegrains is associated with reduced risks of coronary heart disease, type 2 diabetes, and all-cause mortality compared to refined carbohydrates.
Replace refined grains (white bread, white rice, regular pasta) with wholegrain versions (wholewheat bread, brown rice, wholegrain pasta) in your regular meals. This simple swap provides fiber and resistant starch that help lower cholesterol and stabilize blood sugar, reducing your risk of heart disease and diabetes.

Other health effects of regular consumption of wholegrain include reduced total mortality, reduced cancer mortality at certain sites, and a reduced risk of coronary heart disease (CHD), ischaemic stroke and type 2 diabetes (Smith et al. 2006).
Why this rating
The paper cites observational studies (Smith et al. 2006) and notes that wholegrain consumers often have healthier lifestyles, introducing potential confounding.
