The Limitations of Nutritional Studies

This article does a decent job summing up why it’s difficult to conduct good nutritional research.

  1. It’s not practical to run randomized trials for most big nutrition questions.
  2. Instead, nutrition researchers have to rely on observational studies — which are rife with uncertainty.
  3. Another difficulty: Many nutrition studies rely on (wildly imprecise) food surveys.
  4. More complications: People and food are diverse.
  5. Conflict of interest is a huge problem in nutrition research.
  6. Even with all those faults, nutrition science isn’t futile.

When it comes to deciding what to feed Nora, I want to take an evidence-based approach, but focusing solely on randomized trials completely misses the forest for the trees. So there’s good reason to look to food culture and food traditions instead.
