Lean Green Machines!

An apple a day keeps the doctor away…right???

This is Sandra Tsing Loh with the Loh Down on Science.

For years, researchers have wanted to find the healthiest diet. But perhaps all this time the answer was much more GREEN than we expected. 

That’s what Khawlah Alateeq and researchers from Australian National University CHOWED DOWN to find out.

The team surveyed over sixty thousand participants on their diets. They scanned participants’ brains to quantify brain volume and signs of aging.

Participants who consumed more magnesium-rich foods, like leafy greens, had higher brain volumes. Which they believe is related to better brain health. These participants also had fewer signs of aging in their brains., And they found this effect was particularly pronounced… in women!

With this study, researchers hope to inform lifestyle choices in older adults. Overall, helping us live longer, healthier lives! 

Now that’s what I call lean green fighting machines! With occasional chocolate breaks.
