Naturally Occurring Food Toxins
TL;DR: The purpose of this review is to provide a toxicological and regulatory overview of some of the toxins present in some commonly consumed foods, and to discuss the steps that have been taken to reduce consumer exposure, many of which are possible because of the unique process of food regulation in the United States.

Safety evaluation of a high lipid Whole Algalin Flour (WAF) from Chlorella protothecoides.
TL;DR: High lipid Whole Algalin Flour did not elicit skin sensitization in a repeat-insult dermal patch test which indicates little potential for food allergy, and statistically significant effects were noted for several endpoints, none was test-substance related.

Developmental and Reproductive Effects of SE5-OH: An Equol-Rich Soy-Based Ingredient
TL;DR: A new equol-rich soy product has been developed, based on the bacterial conversion of daidzein, and its reproductive and developmental toxicity has been evaluated in a two-generation study and a developmental toxicity study with Sprague-Dawley rats at dose levels of 200, 1000, and 2000 mg/kg/day by gavage.
