(Health News) As the western diet continues to demand vast amounts of land and water for production, a team of researchers at the Tufts University in Boston and the University College London has looked at the potential of cultivating microalgae as a potential food source in the future. The researchers have cited data from the United Nations, which indicates that more than 800 million people currently suffer from undernourishment. This is expected to increase to up to three billion by 2050, the experts add.

The scientists note that this entails meeting adequate calorie requirements for each person, all while simultaneously ensuring that a balanced diet is still met. However, the research team stresses that the current processes involving food production are causing excessive pollution and are exploiting the planet’s natural resources beyond their limits. Likewise, the scientists have noted that demands for small fishes as feed for larger, commercially raised fishes may slowly deplete wild sources.

“As we push for ever more protein- and omega-3-rich foods, we are simultaneously destroying the world’s ocean and terrestrial ecosystems and expanding meat consumption by replacing forests with cropland and pastures and degrading soils. But if our nutritional preferences put us on a collision course with nature, why do we stick to them so avidly? If the majority of marine omega-3 fatty acids originate from algae, why not cut out the middle fish? The potential of marine microalgae as an alternative omega-3 and protein source is well-studied,” the researchers report in The CRISPR Journal online.

In line with this, the research team has highlighted the potential of microalgae as an alternative food source. The scientists stress that microalgae contains significantly high levels of omega-3 fatty acids and amino acids. For instance, the Nannochloropsis oculata or Nanno, contains 40 percent protein by dry weight. It also contains one-third amino acid and six percent omega-3 fatty acid. However, the researchers have added that while these microorganisms are primary fish food, the fish merely acts as an intermediary factor in the nutrition cycle and may not provide equally beneficial effects compared with direct consumption of microalgae.

Challenges in potential microalgae consumption remain

The experts have also observed that very few algal species are currently being utilized in the production of food ingredients, food supplements, and aquafeed. This means that hundreds of strains of microalgae remain untapped. However, the experts have cited challenges — such as cultivation technology and stringent policies — that currently prevent microalgae from becoming a primary food source.

The researchers note that cultivation technology entails that microalgae cultivation requires consistent quality and cost-effective production in order to be classified as a relevant food source. However, the experts have noted that algal composition remains a big challenge.

“Since algal composition changes with environmental conditions (e.g., temperature, light, nutrient composition, mixing, etc.), obtaining consistent algal quality in outdoor cultivation is not straightforward. Fermentation and indoor cultivation technologies have an advantage in this aspect, as growing conditions are highly controlled. Using agro-technologies and cost-effective, sustainable inputs (e.g., low-carbon renewable energy, nutrients and carbon source) are some of the effective ways to reduce production cost. Regarding labor costs, in some instances, a technological solution needs to be adopted to replace physical labor,” the researchers explain.

The experts have also noted that processing technologies that would extract essential nutrients from microalgae are scarcely available. Likewise, the research team has stressed that the current standards required for marine microalgae to enter the food market remains highly difficult. Moreover, the scientists point out that freshly harvested microalgae is a perishable product. This means that careful handling procedures are needed in order to maintain their beneficial properties.

About lijimae2012

My grandmother was a herbalist. She taught me how to mix herbs to cure ailments. I grew up with her from the age of 15 years old. I was going to school  and at the same time returned to her shop of herbs learning different kinds of mixture of herbs and also their names. I have been involved in herbal mixture and I also used it to cure a lot of people who orthodox medicine could not cure even though a lot of people have abused herbal medicine. Selling herbal mixture, popularly called agbo, has also been a great source of income to me and my family. Why I Started This Home Remedies Blog As an educated herbalist , i have been into these work for some years now which  I have help so many peoples. One good-day  i thought about people who are not benefit from these like those outside the Nigeria or peoples who are shame  to seek for a herbalist. Then i decides to create a website so as they can contact me and i would gladly help them. I began this blog in 2017 out of a desire to share my passion for herbs and natural living with others. Above all, am a Muslim and am thankful for the daily love and grace Allah bestows me. I’m glad you’ve visited me here at my home on the web and hope you will join me as I continue down the road to healthier living and my mission to help peoples across the nation! Let’s Connect I would love to connect with you!  Feel free to subscribe to receive free regular post updates in your inbox!  Also, you can find me on facebook, twitter,
