Furthermore, its preventive effects against oxidative stress and DNA damage are well described [6].
These off - target effects may actually be beneficial in treating IBD, primary sclerosing cholangitis, primary sclerosing cholangitis / IBD - related CRC, and asthma, whereby a multitude of abnormal signaling involving inflammation, oxidative damage, DNA damage, and apoptotic abnormalities exists to manifest itself into a diseased state.
However: at present there is no compelling causal evidence to show that nuclear DNA damage alone has a significant effect over the present human life span in comparison to other contributions to degenerative aging.

Fact is, toxicological studies of the effects of algae (primarily spirulina) consumption on humans and animals, including feeding as much as 800mg / kg, and replacing up to 60 % of protein intake with algae sources, have shown no toxic effects, and in contrast, algae intake has actually been found to prevent damage caused by toxins that affect the heart, liver, kidneys, neurons, eyes, ovaries, DNA, and testicles.
Viewing cancer as a metabolic disease — opposed to a disease of damaged DNA, which is a downstream effect of mitochondrial dysfunction — gives us the power to control this dysfunction by carefully choosing foods and nutrients and employing strategies that help optimize the biochemical pathways that suppress cancer growth while simultaneously stimulating mechanisms to push it into remission.
