Thanks, Demi. Appears to be another vague epidemiological study relying on self reporting (notoriously inaccurate) that correlates food types with brain health without clarifying what the diet is and not understanding the role of each food type. No mention is made of fat type consumption or how much meat consumption is considered healthy, if any at all. With recent, sound research regarding saturated and monounsaturated fats positively contributing to brain and cardiovascular health, this "study" appears to be based only on correlation and cannot remotely presume causation.
