Is Too Much Protein Bad for Men's Heart Health?

Is Too Much Protein Bad for Men's Heart Health?

However, proteins from fish and eggs were not associated with heart failure risk in this study.

Speaking on Today Extra, Dr Brad McKay explained most people don't need to go on a high-protein diet because the amount you need each day is probably less than you think.

The research investigated the association between protein intake and survival in 2,281 patients, with an average age of 68 years, and who were all diagnosed with heart failure.

The results showed that for the 334 cases of heart failure cases diagnosed during the study, 70 per cent of the protein from animal sources and 27.7 per cent from plant sources were accountable.

A separate study that was recently presented at the World Congress on Acute Heart Failure in Vienna found that eating protein can help patients with heart failure to live longer - quite the opposite result.

In middle-aged men, there was a trend toward increased risk for heart failure with higher intake of total protein. The researchers split the men into four groups based on their daily protein consumption and analyzed the different rates of heart failure. These diets have some risks too, Virtanen added.

It was found that the risk among middle-aged men was 33% higher for all sources of protein, 43% higher for animal protein, 49% higher for dairy protein and 17% higher for plant-based protein. Only proteins from fish and eggs were not associated with heart failure risk in this study, researchers said.

The U.S. government recommends that people consume about 0.8 grams of protein per kilogram of body weight, or 0.36 grams per pound of body weight, which would translate to about 56 grams a day for a 155-lb. sedentary man, and 46 grams per day for a 130-lb. sedentary woman.

It largely depends on the level of physical activity. For example, it's not clear whether it's protein itself, or other things associated with a high-protein diet, such as the lack of certain nutrients, that could affect heart health, said Allen, who was not involved in the study.

Many dieters turn to a protein-rich meal in a bid to lose weight and avoid carbohydrates; however, the researchers of this study say that comes with its own risk.
