Mediterranean Diet May Help Protect Heart and Brain

Topic: Health

A new study found that eating a Mediterranean-style diet can increase levels of two tiny proteins in the body. These proteins, called humanin and SHMOOSE, may help protect against heart disease and brain damage. The study looked at older adults who followed a Mediterranean diet and found that they had higher levels of these proteins.

A team of researchers from the USC Leonard Davis School of Gerontology led by Roberto Vicinanza studied how a Mediterranean-style diet affects the body. They found that older adults who ate this type of diet had higher levels of two tiny proteins called humanin and SHMOOSE in their blood. These proteins are produced inside mitochondria, which are like the powerhouses of our cells.

Mitochondria are responsible for generating energy for our cells, but they also release chemical signals that affect how we age. The researchers think that these microproteins may act as messengers that help our cells function and age properly.

The Mediterranean diet emphasizes eating foods like olive oil, fish, legumes, fruits, vegetables, and whole grains. It limits refined carbohydrates, heavily processed products, and foods high in added sugar. Decades of research have shown that this type of diet can lower the risk of heart disease, diabetes, cognitive decline, and premature death.

The study looked at blood samples from older adults who followed the Mediterranean diet to different degrees. The researchers found that those who ate the most Mediterranean-style foods had higher levels of humanin and SHMOOSE in their blood. They also had lower indicators of oxidative stress, which is a type of cellular damage caused by unstable molecules.

The findings suggest that individual parts of the Mediterranean diet may contribute differently to mitochondrial health. For example, eating more olive oil was associated with increased levels of humanin, while eating less refined carbohydrates was linked to higher levels of SHMOOSE.

Why It Matters

This study is important because it shows how a simple change in our diet can have a big impact on our health. As Indians, we are at risk for heart disease and diabetes, so learning about the benefits of the Mediterranean diet can help us make healthier choices. By eating more fruits, vegetables, and whole grains, we can reduce our risk of these diseases and live longer, healthier lives.
