Oats and Scotland

Oats are part of Scottish life, from porridge to oatcakes to haggis. I have a theory that oats created the great Scottish character. From the 1700's onwards Scots became a race that travelled and worked all over the world and are reknowned for their hardiness in all climates.
My chiropractor was telling me to stop eating wheat products as the human body just doesn't work well with wheat, our digestive system cannot easily absorb it. This led me to think maybe thats why Scots have a reputaiton for being hardy, mostly they didn't eat wheat until the last 50 years or so. I know that oats are good for reducing cholesterol and are very healthy.
We eat old fashioned rolled oats and we love it the taste is just very good.
