    Thank you for yet another very useful podcast. A great reminder for those of us who used to follow a vegan diet because it was thought to be the healthiest way of eating.
    I think that one of the things that still haunts me so to speak is the IGF-1 connection when it comes to eating meat and dairy – even the best 100% grass fed beef and raw dairy. I would be grateful for your point of view on that…tied to the amount of optimal protein which you believe is required to maintain healthy muscle mass.
    Thank you again for all that you do.

    Would you comment on what is the best sweetener to use? I think in the last podcast John said that it’s a widespread but incorrect belief that agave is the healthiest choice. I was under that impression because I had read its glycemic index is low. What is the problem with agave and what would you recommend instead? Thanks.

    • Hi Nancy,

      Agave often gets the halo because it has a low glycemic effect. The reason for that is agave’s sweetness is mostly from fructose, as much as 85%. I think of fructose as having a “dose-effect”. For many, more than 25 grams/day can accelerate fatty liver and de novo lipogenesis, perhaps worse in people with pre-existing insulin resistance. I would examine it in the context of your total diet. If you do not get too much fructose e.g. from sugar, HFCS, processed foods, soft drinks, then occasional agave in moderation may be just fine for you. It appears sweeteners like stevia leaf and if tolerated, sugar alcohols like erythritol or xylitol are good alternatives.

    Hello-Thank you for your work. I am an RDN working for a local healthcare organization, trying to integrate functional nutrition when and where I can. This particular podcast was timely for me, as I am working on updating curriculum for a wellness program I will be teaching this Spring. I feel you touched on some important points that I would like to elaborate on in my class to help my students navigate the complex world of nutrition in a food environment that does not support health. What would you say is a good resource for some solid facts regarding macronutrient balance in our diet and healthy choices within macronutrient groups. I appreciate your time.
