While many popular diets advise people to consume large amounts of protein, the animal-based form carries high risks that could see you shave years off your life
A popular food habit that countless Brits follow is one that should be approached with caution.
The well-intentioned habit could actually shave years off your life rather than adding to it. It is, of course, eating too much animal-based protein. High-protein diets have been hailed as the answer to weight loss and a healthier existence in recent years, but experts say it’s not as simple as it’s being presented.
However, the nutrient is still incredibly important for a healthy life and becomes even more important as we grow older. Dr Suzanne J Ferree, who works in family, anti-ageing and regenerative medicine, told the Huffington Post: “The common theory is that we need to cut protein-rich foods as we age, but the research actually only supports this in younger people, not in those of us over 50.”
Suzanne’s claims are backed up by scientific research which indicates that older people need more protein compared to their younger counterparts. This is mainly because our bodies lose muscles as we age. At present, health officials recommend 50 grams of protein per day when combined with a healthy 2,000kcal diet.
However, the problem isn’t protein. It’s the type of protein people choose, with most opting for the unhealthier form – animal-based proteins. Research suggests that it is far riskier to consume animal products than plant-based proteins.
“A common mistake is the overemphasis on consuming a high-protein diet, particularly one rich in animal-based proteins, with the belief that it is essential for longevity and muscle preservation. Many people assume that the more protein they consume, the healthier they will be, leading to an overconsumption of animal products like meat, dairy and eggs,” said Dr Monisha Bhanote, another expert in longevity.
“Excessive consumption of animal-based proteins can actually accelerate ageing and undermine cellular health, contrary to popular belief,” she added. The reason for this is two harmful compounds – advanced glycation end products (AGEs) and trimethylamine N-oxide (TMAO).
“AGEs are harmful compounds that form when proteins or fats combine with sugar in the bloodstream,” Bhanote said. Animal-based products that are grilled, fried or roasted are high in these compounds and can lead to oxidative stress and inflammation – the main causes of the ageing of cells.
One of the main culprits in the overemphasis on protein is the ketogenic diet. This fad diet prioritises the consumption of fat and protein and essentially cuts out carbohydrates. For many people following the routine, foods like meat and eggs are eaten in abundance.
