Guest guest Posted July 16, 2004 Report Share Posted July 16, 2004 Getting back to EFA's. I found an article about rhesus and visual acuity. Eyesight is precious and my 96 yo neighbor had mac degeneration. So I think I add an oz of walnuts to my food. Walnuts are 4 x the calories and twice the price, but I like natural food. Also I don't have to add n-6. ratio is 9/2, n-6/n-3. That won't stop my eating pesto, tho. That green stuff in olive oil must mean something.

Guest guest Posted July 16, 2004 Report Share Posted July 16, 2004 Hi JW: Do you know what the ingredient is in walnuts that has this beneficial effect on eyesight? I would like to get it from something that is NOT loaded with ALA (which walnuts are, unfortunately). Rodney. --- In , " jwwright " <jwwright@e...> wrote: > Getting back to EFA's.

Guest guest Posted July 16, 2004 Report Share Posted July 16, 2004 Rodney, 1 oz of walnuts has the 2 grams of ALA I think I need. The visual acuity was the only thing I've found so far to justify the n-3. I pointed out that the control of the AA production is silly, because people eat meat which is a ready source of AA. SO why do we need n-3, if not for visual acuity?

Guest guest Posted July 17, 2004 Report Share Posted July 17, 2004 I am interested in your statement that "unless walnuts are bought in the shell the ALA will be rancid". Could you give us any references on this, or is this just a supposition on your part? I often eat unshelled walnuts from Fisher Nuts which certainly taste very fresh. Any further information you could provide would certainly be appreciated. Sandy Quote Link to comment Share on other sites More sharing options...
Guest guest Posted July 17, 2004 Report Share Posted July 17, 2004 Sorry, I meant to say "I often eat shelled walnuts from Fisher nuts" not "unshelled". I certainly understand the theory that nuts still in shells should be fresher, but does anyone know of any research or tests of any kind that shows that all shelled walnuts contain rancid oils? I beleive that some companies spray their bags of shelled nuts with BHT, and also reccommend storing them in the freezer which is what I do. Of course I realize they were shipped on unrefrigerated trucks to the store where I bought them. But I am still wondering if there is evidence of some kind that all shelled walnuts contain rancid oil. I recently bought some unshelled walnuts and was surprised to find that they did not look or taste as fresh as the Fisher shelled walnuts that I had been using. Any comments from those of you who are knowledgeable on this subject would be appreciated. Sandy Quote Link to comment Share on other sites More sharing options...
Guest guest Posted July 17, 2004 Report Share Posted July 17, 2004 Isn't it specifically DHA that benefits visual acuity, not ALA per se? Plus, unless walnuts are bought unshelled, the ALA is going to be rancid. The LOX and COX pathways involved in chronic inflammation are produced from Arachidonic Acid. Saturated fat and arachidonic acid seem to be closely related in food.

Guest guest Posted July 17, 2004 Report Share Posted July 17, 2004 Hi Logan: Great stuff! Thanks. The following link confirms your comment about DHA/Macular Degeneration. It also mentions other nutrients necessary to ensure maximum eye protection - it mentions DHA; 'antioxidants' in general; beta carotene; vitamins C and E; zinc and lutein as retarding the progression of macular degeneration. It looks like a believable site. Another reason to eat fish ; ^ ))) http://www.eyeadvisory.com/macular_degeneration.html http://snipurl.com/7tva Rodney. > > Rodney, 1 oz of walnuts has the 2 grams of ALA I think I need. > > The visual acuity was the only thing I've found so far to justify > the n-3.

Guest guest Posted July 17, 2004 Report Share Posted July 17, 2004 Probably true, but recall I was looking for reasons to justify the 2 gms or so of ALA. My argument is that the AA logic of controlling AA production doesn't make sense if you eat meats. So is there a reason to justify ALA 2 gms as an EFA? We're concerned because of the association with prostate cancer (no small thing for men planning to live to 100yo). There is still no concensus, but I can believe an excess should be avoided. The visual acuity thing is a rhesus study. So we can say temp that DHA takes care of the eye problem, although I have no idea how much. Try searching on ALA and CVD, eg. The rancidity issue is everywhere, in anything. I just got some salmon caps that smell like shxx. The 8 oz of flax oil I bot about 3 yrs ago smells and tastes alive and well in the frig. Everything that's shipped comes in unrefrigerated trucks, email or health food store. I figured that something that comes in a food that hasn't been squeezed, cooked or processed maybe has the least oxidation. What criterion to use? All polys are going to oxidize and that's one reason I decided not to add oils a long time ago. And beware of sale merchandise. I'm not sure the 18:3 in walnuts is ALA. Duke's says Linolenic but articles refer to walnuts like they had ALA. Getting consistent data is not easy. Walnuts also contain n-6, beta-Sitosterol, and mono fats (for energy). So the walnut adds 2 or 3 things in one package for less than 0.25$ /day. I believe AA and chronic inflammation are related, BTW, at least in my case.
