Is Meat & Dairy Making You Dumber?!

I came across a great study recently that I wanted to share with my viewers, and one I hope you all pass around!

It should also be another entry in a series of wake-up calls for those who continue to consume animal products.

This was an epidemiological study conducted by the University of Harvard, which monitored 6,183 human female participants, who were all over the age of 65, for 4 years.

The purpose of this study was to find a relation between dietary fat types and cognitive changes in a healthy older population.

The study was well-controlled, as the women were free of cancer (except skin cancer), never had heart attacks, strokes, neurologic dysfunction, liver disease, renal disease, stomach ulcers, and gout.

Women using corticosteroids, anti-coagulants, or supplementing vitamin A and E were excluded.

The researchers also noted histories of hypertension, elevated cholesterol, diabetes, smoking, hormone use, depression, activity level, and alcohol consumption.

They also tracked their calorie and macronutrient intake.

This included the amount of saturated fat found in the processed foods, dairy products, and fatty meat that the women ate.

As well as their consumption of monounsaturated fat as found in olive oil, nuts and avocados, as well as the polyunsaturated fat as found in sunflower oil, corn oil and groundnut oil, and finally the trans-fat found in processed foods.

Before, during and after the 4-year study, the researchers analyzed the women’s cognitive capacity by way of standard testing procedures.

The results?

Higher saturated fat intake from animal sources, such as meat and dairy, was associated with significant decline in areas such as general cognitive abilities, verbal memory, verbal function, as well as the recall of verbal information.

Whereas higher mono-unsaturated fat intake, from plant sources such as olive oil, nuts and avocados, lead to significantly improved scores in all of those areas.

Poly-unsaturated fat intake from plant sources, and shockingly trans-fat intake from processed foods, did not produce any statistically-significant effects in either direction.

That being said, the researchers concluded that the women in this study ate too little trans-fats to find a relationship, as they certainly theorize there to be one.

So ditch the harmful animal products, and get in on the healthy plant foods!

Go vegan!

Unless… you’re cool with the idea of getting progressively dumber over time.
