What did we actually learn about GM foods and tumors?

There’s been a great furor recently about a study which purports to show that rats fed GM corn develop more …Continue reading »... Read more »

About Correlations: Alcohol and Diabetes/BPA and Endocrine Disruption

by ABK in Environment and Health

From a purely health-oriented perspective, alcohol is one of those things where a little seems to be good and more than a little puts you at risk for a bad health outcome. One of the positive things small regular intake can do for you is protect you from diabetes. There is good epidemiological evidence that this is the case. Light drinkers are less likely to develop diabetes than those who abstain. Samples prepared for analysis.  As most people know, just because two things occur toget........ Read more »

Paleo and CrossFit: A Chemical Conglomerate Targets a Small Business.

by ABK in Environment and Health




I usually try very hard to stay out of strategic maneuvering.  It has always seemed dishonest and sneaky and I'd rather not be anywhere near it.  But . . . there's some interesting stuff going on the world. And it might impact health. I tried to post this on my other website, but I'm having trouble getting it to list properly. .  Eastman Chemical company has filed a lawsuit against a tiny company (Certichem, see earlier post) that tests chemicals for estrogen activity.&nbs........

In a Nutshell: Alcohol and Diabetes

What are Obesogens and do I need to worry about them?

by Andrea Kirk in WODMasters




Most of this post has appeared on my Environmental Chemicals Blog, which is now being used as an example blog for a Biology course with a Science Blogging component. However, I thought it might be an interesting read for people who, despite eating well and working out like fiends, are still struggling to lean out. It is also a good read for people who want to protect their children, future children or grandkids from metabolic disorders later in life.

CrossFit and Paleo: Do high fat diets increase the risk of diabetes?

by ABK in Environment and Health







I'd written a while back about a relationship between eating a high fat diet and risk of diabetes.   This is an interesting topic and one might wonder why the two should be linked together.  There has been some work on this, notably  Chiang et al. 2010) who investigated two different types of high fat diet along with a low fat diet using mice. cause by experimenting with mice.  The one of the high fat diets contained fresh soybean oil while the other used oil that had b........

CrossFit and Paleo: Plastics, Obesity and Diabetes

by ABK in Environment and Health





This post covers one of the problems posed by endocrine disruptors (ECDs) that I don't think has gotten a lot attention, or at least broad enough attention. This is the issue of estrogen-mimics.  These are also known as Xenoestrogens.    A lot of people seem to be aware of BPA and take steps to avoid it. However, BPA is a relatively small part of the story. Plastics labeled BPA-free may not be Estrogen Activity-Free at all (Yang et al. 2011).

Should oxygen be given in myocardial infarction?

by Rogue Medic in Rogue Medic

In 2010, a Cochrane Review showed something that we already knew, but wanted to keep ignoring.

There is no evidence that supplemental oxygen improves outcomes for patients having an acute myocardial infarction, but there is evidence that oxygen is causing harm to these patients.

Should we continue to treat these patients with supplemental oxygen in the absence of either hypoxia or respiratory distress?

Dan Atar, professor and head of cardiology, wrote –... Read more »

An Introduction: What are Endocrine Disruptors?

by ABK in Environment and Health

The next several posts will be devoted to the subject of endocrine disruption with a focus on environmental chemicals that interfere with sex steroids, chiefly estrogens and androgens.

Most people are probably familiar with estrogen and testosterone. These are steroids produced by the human body (and the bodies of other species) that play important roles in sexual development and reproduction. They also play many other related roles, influence growth and tissue maintenance, neurological fun........ Read more »

Heat dissipation is key to athletic performance

by Andrea Kirk in WODMasters

Work on the effects of heat on athletic performance continues (see earlier post "What are we fighting when we try to push through a challenging workout" for in depth discussion). This is an important area of research for most of us because heat may be the limiting factor in performance. You body will try its best to make you stop exercising when your brain temperature reaches a certain level. Muscle cells will also start to function poorly when they are heat stressed. This is due, in part of........ Read more »

The Paleo Diet and CrossFit: making sure you get enough iodine.

by ABK in Environment and Health


The Paleo Diet is very popular among CrossFit participants and is often advocated by CrossFit Boxes (gyms).  It consists of basically meat, vegetables and some fruit and excludes grains, beans, dairy products and limits or excludes salt.   This may pose a nutritional risk, in that people may end up severely limiting their iodine intake.  An additional risk for people who drink a lot of water, as many health conscious people do, is that they may flush out more iodine than peo........

Hormones, Mimics and Canned Food

by ABK in Environment and Health


Canned foods have plastic liners.  If they didn't we'd probably need to worry about metals leaching into foods.  The liners serve a protective function.  Unfortunately they may pose risks of their own.  Bisphenol A is commonly known as BPA.    It is produced in large quantities for use in plastic products including the linings of tin cans, water bottles, and, until very recently, in baby bottles.

Sweet swag, hip Harvard, & ample alcohol

by NerdyOne in Try Nerdy

I want to talk about a shirt. Specifically, I want to talk about this shirt:

It happens to be one of many Awesome ThinkGeek Shirts. If you are reading this post, then A) you’ve probably already heard of ThinkGeek, and B) there’s a good chance you know what the molecule on that shirt is.

If neither A) nor B) applies to you, though – that’s okay! Because I plan to discuss 1) what the molecule represents, 2) which school I think the shirt is poking fun at, and why it&r........ Read more »
