It would also help to slow climate change, deforestation and the loss of species.
To achieve the healthy diet goals by 2050, global consumption of foods like red meat and sugar would need to be slashed by more than half, and consumption of nuts, fruits, vegetables and legumes would need to be more than doubled.
With the world's population expected to reach 10 billion by 2050, the report argues that current diets, with a growing emphasis on Western-style high-calorie foods high in saturated fats, are unsustainable.
The solution, based on three years of modelling studies, is a diet consisting of around 35pc of calories obtained from whole grains and tubers, and protein mostly derived from plants.
Seek global and national commitment to shift toward healthy diets that feature more plant-based foods-including fruits, vegetables, nuts, seeds, and whole grains-and less animal products.
Those who enjoy eggs in the morning will also be limited to around 1.5 per week, the EAT-Lancet Commission said.
"How we grow, process, transport, consume and waste food is hurting both people and planet", according to EAT, a Stockholm-based nonprofit and organizer of the 37-person commission that wrote the proposal.
In response to the EAT-Lancet report's suggestion that food production systems need to change to predominantly plant-based systems, MII stated: "Ireland's grass-based food production systems provide us with a natural competitive advantage to convert this grass feed into high-quality, nutritious meat protein".Читайте также: Nishikori survives Karlovic test in Melbourne
The Lancet medical journal and nonprofit EAT studied what healthy diets from sustainable food systems should look like. It is overly simplistic to target one food group for a significant reduction in consumption and it ignores its medically accepted role as a key part of a healthy, balanced diet.
At a production level, government must reorient priorities away from simply producing high quantities of food to producing healthy food that also enhances biodiversity, they say.
While the recommended dietary changes might be wrenching for some, they come with a tremendous benefit in terms of human health, said co-lead commissioner Dr Walter Willett, a professor of epidemiology and nutrition at the Harvard T.H. Chan School of Public Health. Globally, more than 820 million people remain undernourished and concurrently, prevalence of diseases associated with high-calorie, unhealthy diets are increasing, with 2.1 billion adults overweight or obese and the global prevalence of diabetes nearly doubling in the past 30 years.
The diet the review suggests, he said, allows flexibility for different agriculture, cultural traditions, and dietary preferences like vegetarianism and veganism.
A worldwide shift toward such a diet would require rapid change and an "unprecedented global collaboration and commitment", the authors said, noting this "objective is uncharted policy territory".
According to this, you'd be able to eat one burger a week, or one large steak a month, a couple of portions of fish a week, with the same amount of chicken.
Christopher Snowdon, head of lifestyle economics at the IEA, accused the authors of the planetary health diet of campaigning for a "nanny state".
