Summary
On episode 76 of 40+ Fitness, Coach Allan sits down with Mark Schatzker, an award winning food journalist and author of Steak: One Man’s Search for the World’s Tastiest Piece of Beef, whose work has appeared in the New York Times, the Wall Street Journal, and Conde Nast Traveler, to discuss his book The Dorito Effect.
Mark argues that nutrition science keeps chasing one variable villains (fat, then carbs, then sugar) while missing a simpler thread: flavor. Whole foods like tomatoes and chicken have been bred for yield and shelf life at the expense of taste and nutrient density, while processed foods like Doritos use flavor chemistry to make bland ingredients irresistible.
The conversation covers what selective breeding has done to produce and poultry, why “vegetarian fed” chicken is actually unnatural, and how consumer demand, the way it reshaped craft beer, could eventually reshape food quality too.

Key Takeaways
- Nutrition science oversimplifies a genuinely complex problem. Decades of blaming a single nutrient, fat, then carbs, then sugar, ignore that both human biology and food itself are complicated systems with many variables, and none of those single fixes has solved obesity.
- Flavor is a more honest lens than any single macronutrient. Looking at what changed in how food tastes reveals two forces that the fat or carb debates miss entirely: whole foods going bland and processed foods getting engineered to taste incredible.
- Whole foods have gotten blander through selective breeding. Tomato yields have risen roughly eightfold since the 1950s because breeders selected for high yield and bruise resistance, not flavor, so today’s tomatoes taste like cardboard and carry less nutrition.
- Chickens are bred to grow about six times faster. A modern supermarket chicken reaches slaughter weight around six weeks old versus roughly sixteen weeks after World War Two, and that speed changes its fat content and cuts its omega 3 levels.
- Flavor chemistry, not nutrition, made processed snacks addictive. The original plain tortilla chip barely sold; adding flavor chemicals to taste like taco, then nacho cheese, is what turned Doritos into something people could not stop eating.
- “Health halo” snacks often are not meaningfully better. Reformulated or baked chips get marketed as healthier, but their actual nutrition labels frequently show little real improvement over the originals.
- Chickens fed only soy and corn do not taste like chicken because they are not eating what chickens evolved to eat. Natural diets of grass, bugs, and seeds gave chicken its flavor; “vegetarian fed” on an egg carton actually signals an unnatural diet, not a healthier one.
- Real, flavorful food is more satisfying in smaller amounts. Heirloom genetic chicken needs almost no seasoning or sauce and leaves you satisfied without the urge to keep eating, unlike bland commercial meat dressed up with flavor add-ons.
- Consumer demand can reverse the trend. Craft beer’s transformation over the past 20 years shows that when enough buyers demand real flavor and quality, the market responds; food could follow the same path if people are willing to spend a bit more.
“When your grandmother or great-grandmother says at a family dinner, you know, nothing tastes the way it used to. That is a correct and empirically proven statement.”
