What are the microalgae and why do we need them on a planet with growing population? We are going to check the benefits of a product that is giving more and more to talk about. Is the nutritional panacea sustainable? Let's see it!
Why do we need microalgae?
La ONU estimates that food production should increase by 70% globally from now to 2050. The reason is the growth of the world population. However, it cannot continue the clearing of forests necessary to raise cattle. Nor the one that has to do with growing soybeans for this. Therefore, the world needs solutions.
One of them resides in the microalgae. These are unicellular organisms that grow thanks to photosynthesis. They are usually the base of the food chain. However, they are of special interest since they can grow almost anywhere. Also, absorb CO2 and have a reduced carbon footprint.
Well, it turns out that several of these species can be useful for human consumption. They can be used to prepare fish substitutes y shellfish. In fact, the properties that fish has are granted to a great extent by its consumption of microalgae.
What benefits do they have?
Today they are grown primarily for the energy sector. Thus, its main function is biodiesel. However, we also have some intended for food. These are: Chlorella, Spirulina y dunaliella. They are very interesting since they present certain benefits for human health.
For example, its carotenoid content ranges between 0% and 1%. These are substances, such as betacarotenos of carrots, large capacity antirust. They are able to prevent certain types of cancer. Furthermore, it should be noted that the species dunaliella can accumulate up to 14% of beta-carotene under high salinity conditions.
On the other hand, microalgae are also a source of proteins healthy. They have the same amount as fish. Thus, these can be used as additives to baby milk or chicken. In this way we can get eggs enriched with omega-3. In addition, it is also worth noting the protein content. The Chlorella It has a 51-58% of protein while spirulina un 60-71%. On the other hand, dunaliella saline has between 50-80%.
Therefore, they have enough more than chicken, 24%, or fish, 24% too. Thus, we end this string of benefits with its high content of vitamins A, C, E and B12. The latter is essential since it is only found sufficiently in meat, as well as in microalgae. They also contain minerals such as magnesium, sodium, calcium and potassium.
Conclusion
Microalgae may seem more palatable than insects outside of Asia. However, its weak point is that proteins are less well absorbed because they lack certain amino acids. That is why the investigation must continue. From this mint we can have a more sustainable and healthier diet while feeding the entire planet.
