According to a groundbreaking new study by the Harvard T.H. Chan School of Public Health, adopting a healthy and sustainable diet can both significantly reduce the risk of early death and help lessen environmental impact. The Planetary Health Diet emphasizes minimally processed plant foods while allowing moderate consumption of meat and dairy. It promotes a diverse intake of whole grains, vegetables, legumes, and nuts, focusing on sustainable eating habits as well.
What this means in real terms is you might enjoy one beef burger and two servings of fish per week with the remainder of your protein derived from beans, pulses and nuts. You may include a glass of milk or some cheese or butter each day and just under two eggs per week.
At a typical meal, approximately half of your plate would be covered with vegetables and fruit of different colours; a third made up of whole grains, followed by plant proteins (beans, pulses), some unsaturated oils with optional but modest amounts of animal protein and dairy and some added sugars and starchy vegetables.
Key Findings from the Study
Published on June 10, 2024 in The American Journal of Clinical Nutrition, the study analyzed health data from over 200,000 individuals for up to 34 years. Participants’ commitment to the Planetary Health Diet was scored based on their intake of 15 food groups.
The study found:
- Participants who followed the Planetary Health Diet most closely had a 30% lower risk of early death.
- Significant reductions in deaths from cancer, heart disease, and lung disease were noted.
- High adherence to this dietary pattern was associated with 29% lower greenhouse gas emissions, 21% reduced fertilizer needs, and 51% less cropland use.
Conclusions
The Planetary Health Diet may offer a dual benefit: promoting individual health and significantly mitigating environmental damage. Embracing this diet may be a vital step towards a healthier future for both people and the planet.
