Gardening is awesome, but how might it boost the brain? Here’s what a 2019 study said about gardening and elevation in levels of a key molecule involved in brain growth. Source: Benefits of Gardening Activities for Cognitive Function According to Measurement of Brain Nerve Growth Factor Levels

This job was linked to a nearly 75% lower chance of dying from Alzheimer’s. Here’s why:

This is one of the most misunderstood food groups around. If you go on social media and hear what people say about beans and other legumes, you probably heard that they are inflammatory and overall bad for our health. This is exactly opposite of what the best data tell us around these foods. In this video, I’m breaking down just a tiny amount of the research and misconceptions around beans and other legumes. If you’d like to learn more, I invite you to check out the following studies. As always, nutrition should ideally be tailored to the individual and population level statistics won’t always apply to a single person. You should work with your healthcare provider to optimize the diet that is best for you.

Eating more of this carb is linked to better health across a number of different outcomes. But the issue is that almost no one eats the recommended amount. In this video we’re breaking down what the fiber content is in one cup of various foods. To be clear this doesn’t mean that these are all equivalent serving sizes. You should tailor your fiber intake to your personal needs.

A recent study found that 80-year-old “super ages” could be growing up to 2.5 times more new brain cells in the memory center of the brain compared to people with dementia. This research has powerful implications for brain health.
