“Oats” good for the heart, good for the health
“Oats” good for the heart, good for the health
Certain naturally-occurring foods, or super-foods, are chock-full of goodness for the human body. One such super-food is oats, which have been a favorite target for research for over half a century due to their well-documented ability to reduce cholesterol. The presence of beta-glucan, a soluble fibre, in large amounts in oats is considered to be the reason for the cholesterol-reducing action of oats.
Early dietary interventions like limiting saturated fats in diet go a long way in prevention of lifestyle disease including heart disease and diabetes and need to be reinforced from childhood. A systematic review of clinical trials focusing on the association between beta-glucan and cholesterol demonstrated that oats are probably the best bet for reducing overall cholesterol and, as a result, the risk of heart disease.
The review included 58 studies, involving nearly 4000 participants, that examined the effect of including oat beta-glucan in the diet on levels of low density lipoprotein (LDL or “bad” cholesterol), non-high density lipoprotein (non-HDL, or total cholesterol without HDL) and apo-lipoprotein B (apoB), all of which are indicators of cholesterol levels in the body. Addition of 3.5 grams of beta glucan in the diet was found to have a positive effect on cholesterol levels, with a reduction in LDL cholesterol by 4.2%, non-HDL cholesterol by 4.8%, and apoB by 2.3%, compared to conventional cholesterol-lowering methods such as diet control. Consequently, the risk of heart disease was also likely to be reduced. It is recommended that inclusion of oat beta-glucan in the form of oat bran (and not oat meal, which contains less beta-glucan) in cereal and baked items could help people with high cholesterol reach their target cholesterol levels faster than simple diet management. However, studies have revealed that oats consumption has been declining over the past decade, so raising awareness about oats’ health benefits needs to be made a priority. more
