Seaweed Proteins

The world is heading to a global food crisis due to the ballooning world population. It needs sustainable sources of dietary protein. The usual dietary protein originates from animal and plant agriculture from which environmental issues like deforestation, water pollution, and greenhouse gas emission arise. Discovering alternative protein sources that are nutritionally adequate for the human diet without harmful environmental effects is imperative. 

Seaweeds contain high concentrations of the essential amino acids required for human consumption. They promised to be  environmental-friendly sources of dietary protein. However, the nutritional values of seaweeds have yet to be compared with other protein sources. A recent technical note published that seaweed proteins are similar in quality to common plant protein sources such as peas, soy, and tree nuts. Seaweed proteins from different species complement essential amino acid profiles and can be mixed to form protein blends that are nutritionally equivalent to animal products such as milk and whey. Seaweeds may be viable protein sources with a reduced carbon footprint that provide beneficial ecosystem services.
