A large study in Finland studied the dietary choices of middle-aged men and followed their health for over 20 years.  The results suggest that a diet high in protein increased the risk of developing heart failure.

But not all protein is created equal as protein from meat and dairy was linked with a higher risk of developing heart failure than protein from eggs and fish.  Protein obtained from plants resulted in an even lower risk.

It is estimated that 20% of Americans aged 40 and above will develop heart failure, a condition which has no cure.  Healthy lifestyle choices and diet are the best way to lower the risk of developing the disease.

It is suggested that preventing heart failure is best achieved through:

•  maintaining a healthy blood pressure
•  maintaining a healthy BMI (Body Mass Index)
•  avoiding tobacco products, especially smoking
•  exercising regularly
•  checking your cholesterol levels often

The study raises many questions, and additional studies are needed to confirm its findings.  This study was conducted on men only, and its conclusions should not be assumed to hold true for women until additional studies are completed.
