The banner image shows an elated young woman with dark hair streaked with reddish-brown, basking in the sunlight. The company’s proposition is bold: “delay the grey.” Why put up with grey hair when we could pop a new pill to “replenish [our] body with the vitamins, minerals and anti-oxidants” it needs to hold onto our natural hair colour?</p> Sat, 04 Sep 2021 08:00:00 +0000 Jonathan Jarry M.Sc. 8835 at /oss /oss/article/pseudoscience-general-science/direct-consumer-2-epigenetic-boogaloo <p>Cutting-edge science can be used to fashion mirages. We are led to believe there is value in the product, a drink to quench our thirst for knowledge.

Some restaurants, particularly in California, are capitalising on this idea. They point out that low temperature cooking prevents the formation of carcinogens, which is in fact correct. They also claim that that low temperature cooking preserves the enzymes in the food. That may also be true, but it is irrelevant. Enzymes are proteins and are broken down in the digestive tract to peptides or amino acids. While tiny amounts of certain enzymes may survive digestion to be absorbed, they have no clinical relevance. The human body does not require enzymes from an outside source; it is capable of synthesising all the enzymes it needs. The one exception to this are digestive enzymes which may have to be supplied in the case of pancreatic insufficiency or cystic fibrosis. In this case the enzymes are encapsulated in a capsule which is designed to resist breakdown in the stomach and release its contents in the small intestine where they can carry out their digestive function. Overcooking can indeed cause problems but this has nothing to do with preserving enzymes. Heat promotes the formation of advanced glycation end products (AGEs), polycyclic aromatic hydrocarbons (PAHs) and heterocyclic amines (HCAs). All three substances are proven or highly suspected human carcinogens. <a href="http://blogs.mcgill.ca/oss/2012/11/06/is-there-anything-to-raw-food-diet/">Read more</a></p> Tue, 06 Nov 2012 23:45:24 +0000 Joe Schwarcz PhD 1771 at /oss
