Apples and Green Tomatoes Could Help Prevent Muscle Atrophy

Apples and Green Tomatoes Could Help Prevent Muscle Atrophy

We all know that our muscles weaken and atrophy as we age. What you might not know is the process is controlled by a protein found in the body called ATF4. ATF4 changes the structure of genes and starves muscles of the proteins they need to grow. Interestingly, researchers have discovered two compounds that could shut off ATF4 and help prevent muscle atrophy as we age.

 

The Study:

The study fed elderly mice ursolic acid (a compound found in apple peels), tomatidine (a compound found in the skin of green tomatoes) or neither for 2 months. The researchers found that mice eating either compounds were able to increase muscle mass by 10% and muscle strength by 30% over the 2 months, equaling the abilities of young mice. The researchers have plans to replicate the study in humans. If similar results are found, it could lead to the production of supplements that will help prevent muscle loss. Until then, adding apples and green tomatoes is well worth trying.

It’s also worth noting that other studies have also found that strength training throughout the ageing process can help prevent muscle loss.

 

Conclusion:

Muscle grow up until about the age of 30. Afterwards, you can lose up to 3% to 5% of your muscle mass per decade. So if you’re over the age of 30, it couldn’t hurt to add extra apples and green tomatoes into your diet. They’re good for you anyway!
