Resistant Starch: Your Questions Answered

potatoes22Last week’s Definitive Guide to Resistant Starch garnered a lot of attention. While the article covered a lot of ground, many of you had lingering questions and concerns about the topic: What is and isn’t resistant starch? How much resistant starch should I be eating? Why is resistant starch good for me? What is resistant starch again?

I don’t blame you; it’s a confusing one that appears, on first glance, to challenge some of the fundamental Primal ideas about food and nutrition.

Today, I’m going to answer as many questions from last week as I can. Hopefully it clears up most of the bigger questions.

Let’s get right to it:

Dear Mark: Wheat Germ Agglutinin and Leptin, Early Allergen Introduction, Fasted Training, Green Bananas, and Sunchokes

wheat5For today’s edition of Dear Mark, we’ve got a five-parter. First, I discuss wheat germ agglutinin’s potential interaction with the leptin receptor. Next, I explore the prospect of introducing gluten and peanuts (among other potential allergens) to youngsters as a way to prevent allergies from developing. I also discuss whether fasted workouts are a sound strategy to boost fat burning, if any good non-nightshade sources of resistant starch exist, and the nutritional benefits of sunchokes.

Let’s go:

Starch: Fallback Food or Essential Nutrient?

roots

I’ve always said that carbs aren’t bad in and of themselves. They’re better in certain contexts and worse in others.

Are you CrossFitting five days a week? Training for the Olympics? Breastfeeding? These are contexts in which carbs are warranted, helpful, and even healthy.

Are you insulin-resistant and hyperinsulinemic? Are you a moderately active person with a few extra pounds? Are you diabetic, or nearly so? These are contexts in which a low carb intake would be warranted, helpful, and even healthy.

Dear Mark: Vegetable Juicing, G_BOMBS, Blood Sugar, and Hot Workouts

vegetablejuiceToday is going to be a bit of a long Dear Mark blog post. I got some great questions from you guys. First, I cover three questions regarding the insulin spike and carb load from vegetable juicing. Next, I discuss the place of G_BOMBS, or the “perfect nutritional combination” of greens, beans, onions, mushrooms, berries, and seeds, in a Primal eating plan. The blood sugar response to meat is next, along with a followup question about how dietary fat affects the glycemic response to eating carbohydrates. Finally, I field a question regarding the utility of artificially increasing one’s propensity to sweat during workouts by turning the air conditioner off. Does it hurt? Does it help? Find out below.

Dear Mark: Should I Increase Carb Intake for Weight Loss?

sweetpotatoes2 1Sometimes, weight loss slows. Sometimes, what worked amazingly well before, stops working quite the same. Although this can be scary, frustrating, annoying, or all of the above when progress slows, stops, or requires new input to continue like it was is ultimately okay, because we are an adaptive species. We can change things up, shift stuff around. Physiological processes (among which weight loss and metabolism can certainly be counted) are never linear – that’s partly what makes all this stuff so endlessly engaging.

Today, I revisit a strategy for overcoming these lulls in weight loss induced by low carb: carb (re)feeds. They seem counterintuitive, sort of, especially if you’ve had success restricting carbs, but hold you opinions until you read on. I think you’ll find it enlightening.
