Protein Overload: Too much of a Good Thing? Top GP Issues Warning
London, UK – A leading general practitioner is cautioning that excessive protein consumption may pose significant health risks, perhaps increasing the likelihood of cancer, diabetes, and mortality. While protein is essential for health, new research suggests that overdoing it can be as detrimental as not getting enough.
A recent study highlighted that adults with the highest protein intake faced a four times greater risk of dying from cancer compared to those following a low-protein diet. Further research indicates that high protein diets may accelerate the growth of tumours, including melanoma and breast cancer, by overstimulating cellular growth pathways.
The concern isn’t solely about quantity, but also the type of protein consumed. According to Professor Charles Swanton, chief clinician at Cancer Research UK, the risk of bowel cancer is “much higher” with daily consumption of red or processed meats.Protein powders have also been linked to increased bowel cancer risk due to their impact on the gut microbiome, potentially triggering inflammation and toxin release.
The study found that roughly 20 per cent of total calories from protein was linked to increased risks of cancer, diabetes and mortality.
GP Dr. Michael Hobson advises focusing on a diverse range of high-quality protein sources rather than fixating on specific intake numbers. “Include a mix of plant and animal protein sources-such as lentils,eggs,soy,nuts,fish,poultry and dairy-to easily hit your protein goals,” he suggests.
Simple additions like nuts and seeds to yoghurt (providing over 10g of protein) or a small chicken breast (around 30g of protein) can contribute considerably to daily intake. Snacking on nuts, cheese, and fruit with nut butter are also effective ways to boost protein levels.
“Remember, most of us don’t need more protein, we just need better protein with a balanced diet,” Hobson concludes.
