This is an opinion piece about food prohibitions "in the guise of science." Written by a Pediatrics professor who talks about the poorly substantiated arguments behind such things as the demonization of salt, and now the gluten-free frenzy. 1 in 5 Americans routinely chooses gluten-free foods according to a 2015 poll even though fewer than 1% of people in the USA have wheat allergies and fewer than 1% have celiac disease. Besides this, gluten sensitivity is not well-defined and most people who claim the distinction don't meet the criteria.

http://www.philly.com/philly/health/health-news/ancestry-dna-genes-23andme-genetics-20171012.html This is a Philly Inquirer piece about people who buy kits for analyzing their DNA. The writer reports that he and his sister had their DNA analyzed and different ancestry was reported for each of them. The results are conveyed via charts and graphs as percentages which, according to the writer, cannot be determined with certainty. Most companies compare snippets of a person's DNA to the company's database of DNA markers from people in various regions of the world. This is where the inaccuracy comes in because in order to find otu where your ancestors lived 500 years ago you would need to compare your DNA to a data base of DNA from people who lived 500 years ago, according to the article.
