So it seems as though the whole gut-brain axis idea is catching on in the mainstream media as per an article in the Sydney Morning Herald. People like Chris Kresser and numerous others have been stressing the importance of maintaining a healthy (non-leaky) gut to maintain good mental / cognitive health for a while and from a high level it makes a lot of sense:
Leaky gut -> toxins and other nasties from your gut into your bloodstream -> nasties cross the blood brain barrier -> impact on your cognitive function. Let's get into it!
To buy grass fed butter in an affordable way (without spending $7-8 per block on something that says "grass fed" on the label) is an exercise in risk management. The risks are that the cows could get fed grain:
As their primary food source
As a backup food source (in winter or drought when there's no grass)
As a treat to produce their milk
So the trick is to find products that tick (or don't tick) the above boxes.
