The growing number of people on the planet: why we will soon have to eat mud

Marketers argue that there are people who are willing to pay a lot of money for the so-called superfoods, for example for mud (thread) from the pond. Writes about this with the BBC.

According to the UN, the world's population will grow to 2023 billion by 8, but recent studies show that our planet is able to feed only 3,4 billion people normally. What do the rest do?

To avoid a global food shortage, a person will have to cross his borders.

And so a modest mud from the pond can come in handy.

Can the world of microalgae and cyanobacteria help feed the world's population, which is constantly growing, or is it just another food fad?

Microalgae and cyanobacteria

Микроводоросли — это одноклеточные микроорганизмы, живущие в соленой или пресной воде, которые питаются с помощью фотосинтеза (процесса преобразования солнечного света на биологическую энергию).

Цианобактерии, или Cyanophyta, — также водные и фотосинтетические микроорганизмы.

По структуре они одинаковые, но микроводоросли — сложнее цианобактерии, и фотосинтез в них происходит по-разному.

The earth contains a huge variety of microalgae, but as food additives, chlorella and spirulina are most often used.

Instagram sensation

A few years ago #spirulina became a social media sensation.

Millions of people shared smoothie recipes, which, thanks to spirulina, had a luxurious emerald color.

It was a new superfood.

Spirulina and chlorella could be purchased in powder or tablet form. Manufacturers have indicated that they are rich in vitamins, minerals, iron and protein.

In London's Yeotown Kitchen, spirulina and chlorella are added to almost all dishes.

There you can try green cookies, ice cream without milk, green energy balls and a blue spirulina cheesecake.

Профессор Элисон Смит, заведующая кафедрой растениеводства в Кембриджском университете, одна из ведущих ученых мира, объясняет, что водоросли употребляли в пищу задолго до появления Instagram: «Есть свидетельства, что несколько сотен лет назад люди в Южной Америке добывали спирулину из прудов, чтобы добавить ее в свой рацион».

Advantages

The high protein content makes microalgae a wonderful vegan alternative to meat.

Today they are added to food in small quantities.

But Andrew Spicer, CEO of Algenuity, says chlorella vulgaris can replace eggs in pastries and pasta.

Spirulina can be used to make mayonnaise, as it resembles egg yolk in composition.

Disadvantages

Let's be honest: not everyone will like the aroma of spirulina.

«Представьте запахи в морской гавани — смесь рыбы, железа или другого металла», — объясняет шеф-повар Саймон Перез.

Color is also not so simple. If you give people green bread, most will refuse.

In addition, lively discussions continue about whether microalgae are really so healthy.

Both spirulina and chlorella contain large amounts of protein, but all scientists agree that they are not a “nutritional answer” to all our problems.

«Спирулина содержит до 70% концентрированного растительного белка и больше аминокислот, чем другие растительные продукты, — говорит диетолог Рианнон Ламберт. — Но это не значит, что она лучше белка животного происхождения».

Microalgae is also a source of omega-3 fatty acids that contain docosahexaenoic acid (DHA) of plant origin.

But they are less digestible than those found in fish.

The same story with vitamin B12, which is necessary for energy metabolism and adequate functioning of the nervous system.

«B12, содержащийся в спирулине, не работает, — объясняет Рианнон Ламберт. — Организм не может эффективно его расщепить».

Food of the future?

Despite some disadvantages, microalgae have significant advantages.

The population of the Earth is constantly increasing, as is the area of ​​arable land. Therefore, it is necessary to look for new ways to feed people.

Unlike other protein sources, microalgae do not require high-quality agricultural land.

«Их можно выращивать в разных местах. В океанах, прудах и озерах. Даже в вашем внутреннем дворике и на снегу», — говорит Элисон Смит.

Microalgae can be grown even in space and feed them to astronauts during long flights to Mars.

Add taste

Итак, принимать микроводоросли — удобное, но для многих из нас не очень привлекательное предложение. Ведь отпугивают цвет и запах.

However, there are scientists who say that this problem can be solved.

Algenuity is developing algae species in which chlorophyll molecules are removed, creating in return a component that has neutral or subtle colors and aromas.

«Мы пытаемся получить веганский источник белка, который можно добавлять к различным видам продуктов, — говорит генеральный директор Algenuity Эндрю Спайсер. — Пришло время новых возможностей для приготовления и употребления пищи».

Will microalgae become the food of the future? It is up to us.
