This is a podcast episode by JJ Virgin (host, four-time NYT bestselling author and nutrition expert) framed as an "Ask the Health Expert" Q&A. The episode includes multiple sponsor/read segments (Wayfair, Earth Breeze, Ray-Ban Meta, Monarch, McAfee) and a listener question about whether daily protein shakes can cause food intolerances. JJ Virgin explains that intolerances develop to proteins, recommends using "clean" proteins (bone broth or plant-based), aims for about 20 grams of protein per shake, and building shakes with healthy fats (avocado, flax, chia, nut/coconut butter), unsweetened nut milk (or water), added fiber, and limited fruit (½–1 cup; no more than two fruit servings/day). She advises avoiding dairy/whey (casein-containing), egg, soy, juice, gluten, corn, and peanuts to reduce risk of intolerance, and highlights resistant starch from just-ripe frozen bananas for gut benefits. The episode closes with subscription prompts.

Questions this episode answers

About 20 grams of protein.

Dairy/whey (contains casein), egg, soy, and commonly offending foods like corn and peanuts; avoid gluten in smoothies.

Unsweetened nut milk (almond, cashew, coconut, flax-based) or oat milk if nut-allergic; water as an alternative.

Use ½ to 1 cup of fruit per smoothie and no more than two servings (pieces) of fruit per day.

Just-ripe frozen bananas (picked as they transition from green to yellow).
