Eat like a pig with high quality amino acids: Episode 133
What a meat scientist wants dietitians to know
Close your eyes. Someone tells you to eat healthier. What appears?
If the answer is a salad, Dr. Eric Berg has some things to tell you.
Dr. Berg is a professor of meat and animal science at North Dakota State University, past president and fellow of the American Meat Science Association, and – by his own description – an overeducated butcher. He’s spent his career studying protein quality, animal nutrition, and the gap between what food labels say and what they actually mean. He joined the Food Bullying Podcast to make the case that animal-source proteins aren’t just an option on a complete plate – for most people, they’re the most efficient path to genuine nutrition.
Why “eat healthy” defaulting to salad is a problem
Dr. Berg uses a simple exercise at his community events: ask people to picture a healthy meal, and most visualize a salad. His response is to walk through the six nutrient categories the body actually needs – water, protein, fats, vitamins, minerals, and carbohydrates – and show what a salad alone delivers against that list.
The answer: water, some fiber, and a carbohydrate component. The rest requires serious dietary engineering to fill from plant sources alone – and even then, one critical factor gets overlooked almost entirely: amino acid quality.
The problem with “high protein” on a food label
Protein labels report crude protein – the total amount present. They say nothing about the amino acid composition or how well the body can actually use what it’s consuming.
Dr. Berg points to a telling example: high-protein bagels with an 11-gram protein claim and a 0% daily value on the label. That zero reflects a low DIAAS score – the Digestible Indispensable Amino Acid Score, the measure the World Health Organization uses to evaluate protein quality. A DIAAS above 75 qualifies as a good protein source. Above 100 is excellent. Many plant-based “high protein” products don’t come close.
Animal-source foods – meat, eggs, dairy, fish – consistently score at or above 100. Even a well-done hamburger retains a DIAAS right around that benchmark. A high-protein bagel does not.
Dr. Berg’s practical fix is straightforward: add two ounces of salmon to that bagel. You’ve made a sandwich and balanced the amino acid profile of the entire meal. Check the USDA Nutrient Database to compare protein quality across foods for yourself.
What the Western diet pig study actually showed
Dr. Berg collaborated with researchers at Utah State University and the University of Illinois to test what happens when pigs – physiologically one of the best human diet models available – eat a diet mirroring what the average American eats.
The results were striking. Pigs on the Western diet:
- Lost muscle mass while continuing to accumulate fat
- Developed acne
- Experienced hair loss
- Developed brittle bones
- Showed elevated blood sugar, triglycerides, and intramuscular fat – the markers of insulin resistance and chronic disease progression
The comparison group ate the same Western diet with one change: sugar was replaced with cooked ground beef. Those pigs continued gaining muscle, accumulated less fat, and showed a dramatically different metabolic profile – until bone issues caught up with both groups, suggesting the Western diet’s other deficiencies remained a problem even with better protein.
Dr. Berg’s hypothesis: the combination of inadequate indispensable amino acids and excess high-glycemic carbohydrates is a primary driver of chronic disease in developed countries – made worse by the drift toward low-quality plant proteins in the name of health. Watch him walk through the full study in his TED Talk.
The amino acid case for pork specifically
Pork is one of Dr. Berg’s go-to recommendations for patients and consumers priced out of beef. It’s economical, nutrient-dense, and routinely underestimated because of the saturated fat narrative.
The primary fat in pork? Oleic acid – the same monounsaturated fat found in olive oil – because pigs are fed corn and that oil gets deposited in the fat. The USDA nutrient database confirms pork chops as a rich source of iron, zinc, and B vitamins. The “other white meat” campaign successfully repositioned pork decades ago; what it didn’t do was adequately communicate how complete its nutritional profile actually is.
Eggs carry a similar case. Affordable, complete amino acid profile, highly bioavailable, and consistently undervalued in the nutrition conversation.
Barbecue Boot Camp: consumer education done right
Fifteen years ago, Dr. Berg and colleagues at NDSU faced the same problem everyone in agriculture communication faces: how do you get people to show up and learn about modern farming practices?
Their answer was to stop advertising the topic and start advertising the experience. Barbecue Boot Camp brought communities together around outdoor cooking – four 30-minute stations covering food safety, nutrition, grilling versus barbecue technique, and a little agriculture context woven in. Towns of 500 people drew crowds of 100 to 200. Presenters were trained to read their audience and pivot to whatever misconceptions came up – because the questions people asked in small-town North Dakota were often the same ones patients ask in a dietitian’s office.
The ripple effect worked exactly as designed. Dr. Berg still gets calls from people two or three connections removed from someone who attended years ago.
How a meat scientist shops for groceries
Dr. Berg reads labels – specifically carbohydrates and added sugars first, price tag second. He’s not ideological about it; he’s looking for the most nutrient-dense protein at a reasonable cost, which usually means conventional meat, eggs, or dairy rather than anything marketed as a specialty product.
His consistent frustration: patients and consumers who’ve been scared away from red meat or dairy by headlines that don’t hold up to scrutiny, and who are quietly losing muscle mass and micronutrients as a result – not from any dramatic dietary failure, but from the slow accumulation of low-quality protein substitutes that look good on a label and deliver less than they promise.
