Although an alkaline diet rich in fruits, vegetables and whole grains may help prevent health problems such as high cholesterol and cardiovascular disease, scientists have found a specific enzyme that is crucial to maintaining a healthy heart.

According to a new study published in the Journal of Biological Chemistry, an enzyme known as calcineurin is crucial to maintaining the normal development and function of heart cells.

Researchers examined mice test subjects and noted that rodents that were missing the protein had a greater risk of heart problems and death.

“We found that when you eliminate calcineurin, a pool of genes that regulates calcium in the heart went awry. This leads to defects in the growth and proliferation of heart cells, heart disease, arrhythmia, loss of contractility and heart failure and disease,” said researcher Dr. Marjorie Maillet.

The scientists also noted that the nutritional supplement, calcium, is also a large component to proper heart function, and that individuals should make sure they have a healthy amount of the nutrient incorporated into their diet.
