Oat Milk

First came soy, then almond. But the people behind Oatly believe they’ve found the best possible milk - Rachel Sugar


Traditional oat porridge was made with flaked oats, but modern versions are more finely milled i.e. they are oat flour. This means they are easier to prepare. Think 1 minute in the microwave. But………. this changes how they behave in the gut. And these changes are NOT necessarily good for us - Sandy On

ObamaCare Good or Bad

Insuring every U.S. citizen by 2014 is laudable but not by creating a bigger and more convoluted mess. However, there is a way out and it's next door!

ObamaCare Is There a Fix

Just ask our northern neighbors, the Canadians. And it’s not defunding ObamaCare, granting everyone the current ‘federal worker option’ or even socialized medicine. For the lack of a better term could it be a SinglePayerPlan, aka Medicare for everyone.

Obamacare, is it on Life Support?

A reasonable prediction seems to be the ACA is here to stay and that efforts to repeal it will, vis-a-vi the British system, become less fervent as people get used to the benefits it offers to them

No doubt allowing people to sell their organs would increase the supply for those awaiting transplants. But would the societal benefits of such a move be offset by a further widening of the gap between the rich and poor?
