I saw Soylent mentioned on the first page, and then this para from the NYT's Well page stood out even more starkly:
>> "Last year, in its nutrition guidelines for cancer survivors, the American Cancer Society noted that eating traditional soy foods — like tofu, miso, tempeh and soy milk — may help lower the risk of breast, prostate and other cancers. But the guidelines do not recommend soy supplements, which tend to be highly processed and not very rigorously tested."
