People often get wrapped up into what is or isn't "good food". As a result, they "fall off the wagon" when they "cheat", because everyone inevitably will "cheat", and go right back to making poor decisions regularly.<br /><br />I've recently been experimenting with exclusion and inclusion phases of a diet to see how my body reacts to different things. It has been quite interesting and challenging. I extend my sympathy for Celiacs, who have no choice but avoid glutens. It can be a challenge to replace that carbohydrate source with other foods.<br /><br />Being able to finance a "whole foods" approach requires some creative budgeting and shopping. Still trying to make time to get to the farmers' markets!

Competitive inhibition is not physiologically relevant in this case; the entire "Zone" diet is based upon this false assumption - drink a liter of linolenic acid or alpha-linolenic, hit your thumb with a hammer and see if aspirin inhibits prostaglandins differently by assessing pain.

My body seems to tell me what I need, when I need it, so I eat that and it seems to work. If I die tomorrow, discard what I just said :)Carilynhttp://www.carilynjohnson.comnoreply@blogger.comtag:blogger.com,1999:blog-2796785757974247915.post-55844298716682253852012-07-27T11:40:29.666-05:002012-07-27T11:40:29.666-05:00It is certainly true that bodies don't measure...It is certainly true that bodies don't measure ratios. Enzymes, however, do occasionally bind to more than one substrate. In that case, relative concentrations, along with relative binding affinities, do make a difference. <br /><br />As an example, methanol and ethylene glycol poisoning can be treated with ethanol intoxification. In that case, the ethanol saturates the enzyme alcohol dehydrogenase, preventing the toxic reduction products of the reaction of the other substrates.<br /><br />Omega 6 FAs and omega 3 FAs do compete for the same enzymes in the eicosonoid biosynthetic pathways. Particularly in the synthesis of the prostaglandins and (if I remember correctly) the thromboxanes. In that case, even if you have sufficient w3's, an excess of w6's leads to competitive inhibition. <br /><br />Bottom line, relative concentrations can matter.<br /><br />The rest of your point on the matter is absolutely valid. You don't need to take supplements as long as you eat real food and avoid the processed foods that generally contain high amounts of w6's. And yes, those foods are awful for many other reasons.Rosshttps://www.blogger.com/profile/09955990241412217784noreply@blogger.comtag:blogger.com,1999:blog-2796785757974247915.post-33204186528473862022012-07-27T06:54:45.247-05:002012-07-27T06:54:45.247-05:00Yay!

I have been drinking it for years after runs, because, well, it tastes great, and it gives my mind and body a glow and happiness. I discovered its positive effects after completing my first 50 mile race. I was sitting at my cooler 15 minutes after finishing, drinking a V8. A guy I had run with some of way walked over and offered me a Deans Chug chocolate milk. It looked more palatable than the V8 at that moment, and after downing it I felt refreshed and happy. Since then I have always craved chocolate milk after a run, not because other people are drinking it, or for health reasons- but like you said, it tastes great!Anonymousnoreply@blogger.com
