Diet and nutrition / Why Paleo?
« on: October 29, 2006, 12:02:04 PM »
More specifically, why eliminate grains?

Personally, after reviewing research journals I find it silly to eliminate them from one's diet. Refined grains and flours are excluded in this opinion as they are obviously detrimental to health.

However, if one can provide legitimate, peer-reviewed research that condemns the use of whole grains in one's diet I'd be curious to see it. Reason being as grains have been linked to improved glucose tolerance/insulin sensitivity, decreased risks of stroke, type II diabetes, and so on.

Also, one can argue the antinutrients in bread prevent a person from taking advantage of nutrients; however, what do they have to say about fermented breads like sourdough (though I believe some sourdoughs are not fermented like SanFran, correct me if I'm wrong), or sprouted whole grains? Both sproutin and fermenting have been shown to break down antinutrients contained in grains.

This is not to mention the various vitamins found in unprocessed grains, and also the high fiber content.

After reviewing some "research" on the Neolithic Agricultural Revolution and it's linking to decreased human health I have also noticed the adverse side-effects are present when the grains become the dominant staple in the diet and protein intake becomes very low. As a result vegetable and fruit intake was most likely lowered.

I do not see the point in eliminating just because our ancestors allegedly never ate them. Though no one can actually prove this, there is of course speculation, however I will admit it does have some basis from various anthropologists. Though who's to say they did not eat grain seats when available seasonally? Present hunter-gatherer tribes take advantage of grain seeds - though they practice soaking, etc. before cooking and of course they are unrefined.

Also I noticed that people like Art De Vany also forbid the eating of legumes, which I personally find rediculous.

To quote a study from the American Journal of Clinicial Nutrition, conducted by Mark J Messina (you can even find this on pubmed for those without access to journals, as the full text is free to view):

Quote
Beans contain several components that traditionally have been considered to be antinutrients, such as trypsin inhibitors, phytate (inositol hexaphosphate), oligosaccharides, and saponins. More recent information suggests, however, that the antinutrient label may be an oversimplification, especially in the case of oligosaccharides and saponins. Trypsin inhibitors from beans can certainly interfere with protein digestion, and in some species of animals do cause pancreatic enlargement and enhance chemically induced pancreatic tumors (56). However, boiling dry beans generally reduces the trypsin inhibitor content by 8090% (57) and there is little reason to think that the amount of trypsin inhibitors obtained by eating commonly consumed beans would exert any adverse effects in humans (58). In contrast to the trypsin inhibitor, the trypsin and chymotrypsin inhibitor (Bowman-Birk inhibitor) found in beans, especially soybeans, has been studied as an anticancer agent (59).

As noted above, phytate is thought to contribute to the poor mineral bioavailability of beans. On average, the phytate concentration in beans is between 1% and 2% (60, 61). Although the effect of phytate in reducing mineral bioavailability in plant foods is an important consideration, it has also been postulated that phytic acid may play a role in reducing cancer risk, possibly because of its antioxidant effects (62). Specifically, it has been suggested that phytic acid may lower the risk of colon cancer (63) and perhaps breast cancer (64).

Miscellaneous / Need equipment? (Particulary Olympic Lifting)
« on: October 20, 2006, 01:16:40 PM »
I recommend Glenn Plendlay

As many Olympic Lifters know, the bar is a crucial piece of equipment during the lifts. Don't skimp on it! On that note, most will come to be ~700 dollars. I found Glenn's website through various other lifting sources (FortifiedIron, Crossfit, etc.), and I gave his equipment a look. I ordered a set of bumpers from him, and the Pendlay bar (only $350), which is AWESOME. Great spin, nice feel, looks nice, the knurling is just right I think, it's just a great bar. Of course if you want to splurge about 700 bucks (without shipping) for an Eleiko by all means go ahead, but I'd look into this first. If you're not looking for a bar with IWF Competition required bar dimensions, I'd inquire about the Crossfit bar if it's still availabe. But, besides a UPS problem all went well and I'm definately pleased with everything.

If you decide to order anything, let him know Dave Winchester referred you.

Introductions / Hello!

Hey everyone, I'm Dave (as you can see :P). Well, I don't know what the usual protocol is for the introductions here so I'll leave that up to you! If you want to know anything, ask away.
