    I was curious about specifics, so I looked it up — 59% of Canada is lactose intolerant to the US’s 36%. I wonder what factors cause a 20% difference. Most of northern europe has low percentages, like the UK where I’m from having 8%.

      I looked up my statistic from healthline which cited some study. I imagine a big part of the difference is the healthcare system. People are gonna be less likely to go to the doctor for the symptoms in the US unless they have money or are desperate for a solution. Others, like myself, figured it out ourselves by process of elimination and might not show on statistics because of that.
