Sir David Attenborough, the iconic broadcaster, natural historian, and author, celebrated his 100th birthday on May 8, 2026. With a remarkable eight-decade career, he has traveled the globe, exploring nature and inspiring countless individuals to safeguard our planet. His dedication to conservation is matched by his commitment to health; according to Attenborough, a primarily plant-based diet is key to his longevity and vitality.
Reflecting on his dietary changes, Attenborough mentioned in 2017, “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.” By 2020, he had further embraced a vegetarian lifestyle, admitting, “I do eat cheese, I have to say, and I eat fish. But by and large, I’ve become much more vegetarian over the past few years than I thought I would ever be.”
In a 2023 episode of Planet Earth III titled Human, he voiced concerns about the environmental consequences of animal agriculture, urging a shift towards plant-based eating. “If we shift away from eating meat and dairy and move towards a plant-based diet, then the sun’s energy goes directly into growing our food,” he stated. “And because that’s so much more efficient, we could still produce enough to feed us, but do so using a quarter of the land.”
In his book, A Life on Our Planet: My Witness Statement and a Vision for the Future, Attenborough emphasizes humanity’s impact on nature, arguing that although transitioning to a plant-based future poses challenges, it holds significant promise for the planet’s health.
Attenborough is not alone in endorsing a plant-based diet; a multitude of scientists and health professionals advocate its benefits. Research has highlighted a link between reduced red meat consumption and lowered risks of cancer, improved cholesterol levels, and diminished chances of coronary heart disease.
The American Institute of Cancer Research warns, “Eating more than 18 ounces of red meat weekly can increase your cancer risk. If you eat red meat, limit the consumption to no more than three portions a week or about 12-18 ounces (cooked). Eat little, if any, processed meat.”
To embrace a lifestyle akin to Attenborough’s, consider substituting red meat with options such as fish, chicken, nuts, beans, and lentils. Additionally, nutrient-rich choices like tofu, tempeh, lentils, and mushrooms offer ample protein and fiber without the high saturated fat content.
Attenborough also attributes his longevity to remaining physically active and spending time in nature, both of which are supported by scientific evidence.
On his birthday, Attenborough received heartfelt messages from admirers around the world through a BBC tribute on Instagram. One admirer expressed, “Please let this man live forever,” while another remarked, “Aren’t we lucky we’ve had him for 100 years so far!?”
Sir David Attenborough turned 100 on May 8, 2026, after an 80-year career spent exploring and championing the natural world.
He credits a mostly plant-based diet as one of the secrets to his long and healthy life.
