Before we get to that, I have to say that in broader terms, the âyou are what you eatâ phrase is quite trueâand recent research would agree.
If you eat a healthy diet thatâs rich in fruits, vegetables, lean protein, and healthy fats, youâre more likely to be at lower risk for a number of health conditions than a person whose diet contains plenty of calories from processed, sugary foods filled with trans-fat.
But a recent study I came across takes this one step further. Itâs become common knowledge that a healthy diet can slow down the effects of physical aging, but this new study shows that itâs possible a calorie-reduced diet can slow down mental aging, too. According to these findings, âyou are what you eatâ applies to both your body and your brain.
Let me explain in a little more detailâ¦
Neuroscientists at New York University have shown that a calorie-reduced diet can stop the rise and fall of activity levels in almost 900 genes that are linked to aging and memory formation. They say that diets with fewer calories from carbohydrates likely deter certain aspects of aging and chronic disease.
Although the experiment was conducted on mice, I do believe these results will stand when it comes to humans. Weâve seen from previous research that diets featuring lower calories and nutritious food can prolong a personâs life by lowering their risk for diseases like type 2 diabetes, hypertension, and heart disease. We also know that if youâre not using the extra energy (calories) youâre taking in, it can lead to the addition of body fat, metabolic problems, and greater difficulties for overall organ function.
What is important to note are the potential benefits of a low-calorie diet for memory and learning ability. By stopping the genetic fluctuations, itâs likely putting less stress on the brain, allowing it to function better for longer.
This adds further support to the theory that whatâs good for the body is good for the brain. Your brain needs fuel, and the best fuels for a healthy brain are healthy fats (including omega-3), fruits, vegetables, lean proteins, and an array of vitamins and minerals. When you have too little of these foods in your diet and too many carbohydrates, sugary foods, high-cholesterol foods, and processed foods, you can experience inflammation and plaque accumulation in your arteries and brain, impairing your cognitive function.
Eat more of these healthy, low-calorie foods to help both your brain and body:
- Leafy green vegetables, such as kale, cabbage, and mustard greens
- Salmon and other cold-water fish
- Dark-skinned fruits and vegetables, such as spinach, eggplant, plums, or prunes
- Extra virgin olive oil
