Beta-glucan in Oats is Your Brain’s BFF.
Oats protect you from a host of debilitating brain disorders. Courtesy, beta-glucan.
Oats are a gluten-free reserve of dietary fibre, unique proteins and various micronutrients. While these whole grains keep you satiated and energized, they may silently be boosting your brain health too.
All thanks to that one unique micronutrient. Know more in the sections below!
Oats and Nutrition
Raw oats contain:
Carbohydrates: 60 %
Protein: 11–15 %
Fats: 5–9 %
Dietary fibre: 2.3–8.5 %
Calcium : 0.54 %
Iron: 0.047 %
Thiamine: 0.002 %
Niacin: 0.032 %
Apart from these nutrients, oats contain active antioxidants like flavonoids, hydroxybenzoic acid, and AVAs (avenanthramides, which are biochemicals specific to oats).
But the game-changing component for brain health is beta-glucan or β-glucan.
What’s more — recent research has shown that β-glucan may also play a pivotal role in managing neurodegenerative diseases.
β-glucan and Brain
In simple terms, β-glucan neutralizes the negative effects of chemicals (free radicals) in the body.
When left “unsupervised”, these free radicals can impair the signalling processes in the brain cells (neurons) and ultimately cause their death or damage (neurodegeneration).
Improper signalling and loss of neurons may trigger brain conditions like memory loss, dementia, Alzheimer’s and Parkinson’s diseases. β-glucan in oats, barley and other whole grains control neurodegeneration, and hence, delay the onset of brain disorders.
β-glucan and the Gut-brain Connection
Our gut is known to inhabit several microorganisms — primarily bacteria.
These “good bacteria” aid in the digestion, absorption and assimilation of nutrients from the food we consume. They also break down complex fats in our diet and regulate blood cholesterol levels. Because the flipside can be lethal!
When their levels are high, cholesterol molecules (in the blood) get deposited on different organs in our body — including the liver and brain. Cholesterol accumulation in the brain is another factor that flares inflammation of neurons and triggers the onset of brain disorders.
By directly and indirectly controlling blood cholesterol levels, oat β-glucan (with the help of “good microbes”) brings down the levels of overall inflammation in our body and keeps brain functions under tight check.
Hence, proved. The role of oats and β-glucan in brain health is multi-dimensional.
