Caffeine in Workout Supplements and the 5 Levels of Fatigue [YouTube]

This presentation covers the effects of caffeine when it’s consumed before, during, or after a workout. We also review how the Five Levels of Fatigue helps people determine which caffeine products (if any) are right for them. In essence, my Five Levels of Fatigue system helps people avoid caffeine toxicity and dependency because it teaches them tricks for matching how tired they are with how much caffeine they really need. For gym rats and athletes, knowing how to use the Five Levels of Fatigue keeps them from using caffeine after a grueling workout when what the body REALLY needs is rest (not caffeine).

Why I’m Carrageenan Girl for Halloween

This year I’m dressed up as the food additive, carrageenan, for Halloween. This unusual (and extremely nerdy food scientist) decision is my response to the rampant use of fear in food marketing and reformulations.

Fooducate Caught being Anti-chemical AND Anti-chemophobia – A Plea from a Food Scientist

 Excerpt: “I’m tired of being told to be afraid of chemicals…

This week alone, I have been told by a fast-casual burrito company to be afraid of Silicon Dioxide; I’ve been told by a face wash company not to put “chemicals” on my face (unless those “chemicals” are vitamins, natural sugars, and/or plant extracts); and I’ve had to ask my former-favorite juice company in the world to PLEASE use some alternative sweeteners instead of my whole day’s allowance of sugar in one bottle.”
