Renowned biologist Sir David Attenborough credits a simple dietary modification for his sustained health and vigor.

Although he hasn’t fully embraced vegetarianism, Sir David is known to have significantly reduced his intake of red meat.

He suspects this change may contribute to his long life. This isn’t a new adjustment; as early as 2017, Attenborough shared insights into his eating habits.

He remarked, “I have certainly changed my diet. Not in a great sort of dramatic way. But I don’t think I’ve eaten red meat for months.”

While he still enjoys cheese and fish, he noted that he has “become much more vegetarian” than he ever anticipated.

Scientific research strongly supports the health and longevity benefits of a predominantly plant-based diet. The 99-year-old has notably curtailed his consumption of red meats like beef, lamb, mutton, pork, veal, venison, and goat.

Consuming excessive amounts of processed meat and red meat heightens the risk of developing bowel (colorectal) cancer, according to the NHS.

Some of these meats contain high levels of saturated fat, which can elevate blood cholesterol if consumed excessively.

Having elevated cholesterol increases your risk of coronary heart disease. If you’re considering slashing something from your diet, it’s crucial to ensure you’re not missing out on vital nutrients.

Neglecting to maintain a healthy and balanced diet can lead to health complications.

Harvard Health experts suggest that those looking to reduce their red meat intake should seek suitable alternatives to ensure they’re getting enough protein.

Daniel Pendick, former executive editor of Harvard Men’s Health Watch, noted that swapping one daily serving of red meat with one of these options decreased mortality in the study by 7% to 19%.

Six excellent alternatives to red meat for extending life include fish, poultry, beans, low-fat dairy products, nuts, and whole grains.
