Don't eat too much red meat.
Too much iron ?
Critical thinking is in free fall. Two reasons.
- Most people do not think. They react. A headline lands and an opinion is born. Emotion first, evidence later.
- Institutions polish the message for the “greater good”. Nutrition is full of this.
Let’s start with Harvard: https://www.health.harvard.edu/staying-healthy/whats-the-beef-with-red-meat
This new red meat and processed meat recommendation was based on flawed methodology and a misinterpretation of nutritional evidence,” says Dr. Frank Hu, chair of the Department of Nutrition. “The authors used a method often applied to randomized clinical trials for drugs and devices, which is typically not feasible in nutritional studies.
It starts well. The doctor says randomized trials are not feasible in nutrition. Why? No explanation. If the result is clear, the cause is clear. That is the point of randomized tests.
Then comes the safe line: “Just don’t eat too much!”
No kidding. Too much of anything is too much. Is the warning about fat?
If yes, say fat. Do not say red meat. Be precise.
Red meat is red because it uses myoglobin to deliver oxygen. Myoglobin binds iron, and iron plus oxygen gives the color.
White meat relies more on glycogen, with less myoglobin and less oxygen. Less iron, paler meat.
So this was never about redness. It is about fat. Or at least it should be.
If the issue is saturated fat, the sentence should be: “Limit saturated fat, whether it is beef fat, chicken skin, or pork belly.”
We have seen this movie before. Eggs were the villain. Cholesterol panic. A few years later, the story cooled down.
Look at basic fat profiles. Pork belly is not a health food. Grass-fed beef is not the bogeyman. Chicken skin can be just as fatty. The numbers:
