There’s another study out saying that if you’re exposed to a low level of oxidative stress, it turns on a protective mechanism in your body and you end up living longer. This is what happens when you exercise – you burn a lot of energy – and that creates free radicals – by products of metabolism – and that turns on protective mechanisms. The studies say that a gene known as Mga2 is turned on and that really facilitates this pathway. It’s another piece of the aging puzzle. Sources (1,2).

Just read an article on the benefits of Astaxanthin, an anti-oxidant. It’s purported to do everything from curing and preventing cancer to giving you more energy and making you feel good.

Wikipedia says it’s present at about 5ppm in salmon, which is 5 mg/kg so you’d have to eat over a pound of salmon per day to get what some people recommend (4mg per day).  But that’s for farmed salmon. In wild sockeye salmon, it can be 10 times as much as that, so you can get astaxanthin pretty easily.

It’s kind of surprising that Odwalla hasn’t added this to their drinks yet. All they have to do is add this one type of microalgae, Haematococcus, to their drinks, just like they add spirulina to their green superfood drink and voila – a new or improved product.

Also we don’t know a lot about the stereochemistry of astaxanthin. Most of the studies have only been done on one enantiomer, while natural astaxanthin comes in 3 main enantiomers.

If you’re gonna panic over swine flu, at least do it correctly. Wear a surgical mask and you’ll get the virus anyway. Why settle for 62% effective when N95 respirators are 98% effective ? Unfortunately all the best fashion choices are surgical masks.

The New York Times would like you to know that putting a child in a bath with bleach can ease its eczema. They neglect to mention that it might cause cancer for the child down the road as well, but oh well. Unfortunately we just don’t know enough about this. As an example, here’s a link to one study on bleach and cancer.

You know lifestyles in America are unhealthy when red meat only increases mortality 30%.

I’m going to stop using the word genius and start saying “capable and well practiced.” As this article says, “The key factor separating geniuses from the merely accomplished is not a divine spark. It’s not I.Q., a generally bad predictor of success, even in realms like chess. Instead, it’s deliberate practice. Top performers spend more hours (many more hours) rigorously practicing their craft.”

The environmental destruction caused by palm oil is shockingly bad. And how do you put a price on that? With a huge tax, that’s how. Or you could just ban palm oil whose origin is uncertified. That’d probably be smarter.

I think every school should consider having a program like this

I very much liked an excerpt from this article: “They say that we know when we are full. But actually, we eat with our eyes, not with our stomach. In one study, we blindfolded adults and asked them to rate “strawberry” yogurt, which was actually chocolate yogurt. Without the visual cue people accepted what they were told. Time and time again, our research found that people will eat regardless of whether they’re hungry: the bottomless soup bowl study (people ate more when the bowl remained full), the chicken wing study (people eat more when the chicken bones are removed from sight) and the buffet studies (people ate more simply because the food was there). Another myth is that our stomach will take about 20 minutes to tell our brain that we’re full. But that only applies when we are consciously aware of what we are eating, not when we are mindlessly eating cheesy nachos while watching March Madness.”

This was the best site I could find to answer questions that avid skiers like myself might have….

really glad I wear a ski helmet. omg, I just don’t understand you could fall in flat terrain and this could happen – even if you’re not wearing a helmet….

maybe she had a pre-existing condition…

maybe this means helmets will become mandatory…even though helmets can’t really save you if you’re going too fast…

As that good first article says, “An average of 39.8 people die each year skiing or snowboarding, according to the National Ski Areas Association, the industry trade group. That means there are .88 fatalities per million days of skiing and snowboarding. On top of these deaths, the NSAA says there are 43.6 serious injuries every year.”
