Tolerance to starches in the diet varies among individuals. Some individuals experience issues like sleepiness and insomnia after consuming starches, while others tolerate them well. Research suggests that the amylase gene copy, responsible for digesting starches, plays a role in determining an individual's ability to tolerate starches. People with a higher number of copies of the gene may tolerate starches better, whereas those with fewer copies might struggle. However, individual differences exist, similar to how some people struggle with dairy while others do not.
This week, Paul talks to Mike Fave, critical care RN, about all things sugar & fructose. They share their thoughts on a recent podcast with Andrew Huberman and Alex Lustig, and why they disagree with certain points made about insulin, fruit juice, and fructose.
