What a diet of the future might look like – Health News Today

At a time when food production is one of the biggest climate culprits, it is essential that we seek out new food sources which can nourish us and, at the same time, not overburden the planet.


More and more people are opting to become vegetarians or, even more radically, vegans.

However, the large majority of people find it difficult to entirely shelve meat in the name of preventing climate change, according to Professor Ole G. Mouritsen of the University of Copenhagen’s Department of Food Science.

“Many people simply crave the umami flavor that is, for example, found in meat. Therefore, it may be more realistic to consider a flexitarian diet, where one consumes small quantities of animal products, such as meat, eggs and milk, alongside vegetables. However, one can also begin thinking about alternatives to the juicy steak—of which there are many,” he says.

In a new meta-study, Professor Mouritsen and Ph.D. student Charlotte Vinther, his colleague at the Department of Food Science, pick up on today’s food trends.

They present alternative sources for protein and healthy fatty acids, while giving their take on what a sustainable diet of the future might look like.

Hello sand lance, gobi and sprat

Among other things, the researchers recommend that we look to the sea for foods of the future.

More specifically, we need to get to the bottom, where species typically associated with being bycatch and industrial fish live. These species emit far less CO2 than beef, pork and chicken.

“The climate-friendly bycatch fish currently used for pig feed or fish oil live near the bottom of the ocean. They include: sand lance, a fish which digs into the sandy bottom to lay eggs; sprat, a relative of herring which is widespread in Danish waters; and the black-mouthed gobi, another small, but tasty and overlooked fish,” explains Mouritsen.

Sprat alone could satisfy 20 percent of Denmark’s protein needs. And by fishing for sprat, we can avoid the over-exploitation of more well-known fish species such as cod, plaice and salmon, explains the professor.

À la carte algae, squid and seaweed

Seaweed and algae are also an overlooked and extremely climate-friendly food source.

However, only 500 of 10,000 species are currently exploited and recognized as food—despite the fact that marine algae are packed with incredibly healthy nutrients and vitamins.

Similarly, cephalopods are only fished to a small extent, with 30 out of approximately 800 species being used for food globally.

“Among other things, this has much to do with our culture and traditions. Food consumption habits take time to change. We have been eating and preparing meat for more than a million years. So even though seaweed, squid and mollusks contain important fatty acids and vitamins, and can taste great, we remain reluctant…
