Organic food has become the fastest-growing sector of the U.S. food industry, with sales that increase by double digits annually. That's a lot of kale flying off the shelves. Buying it makes us feel like we're helping ourselves and the planet. But here's the truth: There are no health benefits from eating organic food. And it is likely worse for the environment.

Water is essentially everywhere in our world, and the average human is composed of between 55 and 60% water. So what role does water play in our bodies, and how much do we actually need to drink to stay healthy? Mia Nacamulli details the health benefits of hydration.

Breakouts are a pain and can happen well into your 40s. While there's no cure to make acne instantly go away, there are a few science-backed tips you can use to help minimize the number of pimples that pop up.

This case study was developed for an introductory biology course with the goal of integrating content (specifically, structure/function, signaling pathways, and homeostasis) while reinforcing general critical thinking skills and the scientific method (generating hypotheses, evaluating evidence, and making predictions). The case is suitable for a flipped classroom and there are several videos associated with it. The case revolves around an obese two-and-a-half-year-old boy who won't stop eating. Students become familiar with some basic concepts related to obesity and leptin signaling through the videos that they watch before class. They then use class time to work through the case (delivered as an interactive slide show, including several clicker questions) to determine the genetic basis for this child's obesity and possible therapies to manage his weight. The case could also be adapted and expanded to be used in a physiology course to explore the interaction of various hormones that regulate appetite and metabolic rate or in a cell biology class to explore JAK-STAT signaling.

Michael Mosley wants to find out how much meat is safe to eat, he arrives in Boston to find out the results of research conducted on red meat and processed meat... Taken from Should I Eat Meat?

Michael Mosley compares the difference between a meat lunch and a vegetarian lunch to find out whether or not it is actually healthier to be a vegetarian?

Michael Mosley looks into the dangerous ingredients added to processed meat that becomes a suspect in causing cancer.

To what extent should corn be used for the production of ethanol? Are we better off producing corn for food or producing corn for fuel? This case study uses a technique called "intimate debate" (also known as "constructive controversy") in order to examine this issue. Each student participates in a set of mini-debates for which there is no audience. Students are paired with a teammate; these teams then take turns arguing each side of the issue while seated across from their opponents who do the same. The session concludes with opposing teams reaching consensus. Detailed instructions are included in the case handout to prepare students for the experience before debate day. This case was used successfully in a sophomore/junior level, general education, environmental biology course. It would fit appropriately into any college course that discusses environmental issues related to farming practices, land use, alternative fuels, renewable energy, or sustainability.

For anyone with a deep, enduring faith in the meaning of nature, it may come as something of a shock to learn that the word "natural" means nothing at all-at least when it comes to the business of marketing processed food. Every year, U.S. corporations sell tens of billions of dollars worth of food products labeled as "natural." Yet, to this day, the Food and Drug Administration has never formally defined the term. The word is a kind of orphan child, undefined by government, misused by industry and without a provenance or a use for the average American consumer.
