We need to focus on diet, and this will require an urgent transformation of the food system which provides the diet. It is at this point we call for the insertion and scaling up of Seaweed into the food system. The protein concentration in Seaweed- especially red seaweed- can be up to 47% and the vitamins in seaweed can provide health benefits including decreasing blood pressure, preventing cardiovascular diseases, or reducing the risk of cancer. For obesity, we have seen evidence of how seaweed- especially brown seaweed- could inhibit weight gain, prevent obesity, and save people battling obesity from the high costs and hazardous side effects of anti-obesity drugs. For example, Seaweed can reduce ocean acidification and when used in animal feed, reduce methane emission from cattle by 82%.
