It really is shocking when you consider that in our grocery stores, 90% of the products are produced in a factory and are clearly unhealthy for you. I think someone that knew a lot about grocery stores once explained this to me - the large food corporations basically rent shelf space as a form of advertising. This is why you have an entire aisle dedicated to sugared cereals, and another entire aisle dedicated to high-fructose corn syrup soft drinks.Tortoise wrote: It's not hard to see why we have an obesity epidemic in the U.S. Just walk into almost any grocery store or restaurant, and 90% of what you'll see on the shelves or the menus is loaded with refined carbs and sugar. It's funny how we often don't notice things like this until we actually start looking for them.
It's mostly the media's fault for endlessly hyperboling and scaring us with the saturated-fat-cholesterol and heart disease connection. Perhaps part of the problem is this occured when we were young, naive and suspectible to "authoritative pronouncements" and so now we are fighting an ingrained emotional terror with wisdom and logic. It's not easy and it sure doesn't help that there is lack of conclusive evidence. And the secondary evidence of saturated fats causing inflammation (cancerific) or hormonal bioaccumulation (prostate cancer) certainly ought to give anyone pause.Tortoise wrote: Now, since a low-carb diet replaces carbs largely with fat since it's difficult to increase protein intake significantly, I just need to convince myself that the decades-old medical theory that saturated fats and cholesterol cause heart disease is complete bunk...![]()
Good point, but Taubes had an interesting response to it in his book:MachineGhost wrote: It's not like meat was as fatty and unbalanced like today's back in Paleo times. I've posted elsewhere that the saturated fat content of Paleo meat was 10% which is the same as today's lean meat.
What Taubes doesn't mention, admittedly, is what fraction of the total U.S. meat supply was comprised of corn- and grain-fed vs. grass-fed before and after the obesity epidemic exploded.The practice of fattening animals on corn, common today, leads to a different fat composition and, per its purpose, far more fat, than does the kind of grazing that herbivorous animals do in the wild and Paleo animals would have done. The question is how relevant is this to human health. In the United States, farmers have been fattening animals on corn since the nineteenth century at least, and yet the explosive increases in diabetes and obesity occurred during the last decades of the twentieth century. It would be relatively simple to test the hypothesis that we're better off eating grass-fed animals than grain- or corn-fed, but so far no such studies have been done.

That's kind of shocking if it's true. Doesn't rancid oil normally taste terrible--almost vomit-inducing? I've eaten some by accident once or twice, and it took hours to get the rancid taste out of my mouth. But the canola oil I use is virtually tasteless so it's hard to believe it could be rancid. Maybe that means oils don't have to be either completely rancid or completely non-rancid, but can be intermediate between the two as the rancidity progresses? Then maybe oils that are only slightly rancid might not (yet) have a greatly altered taste?Gumby wrote: Keep your olive oil in a cool and dark place and use it within a month — otherwise it becomes rancid and breaks down.

Refined canola oils are often stored in clear bottles because they are already rancid and broken down by the time they are bottled.
You're right. Rancid oil is awful tasting and smelling. If any of you have ever walked into a NYC subway elevator, and thought it smelled like a hobo died inside the elevator, that's really just the small of the rancid canola oil that has broken down on on the rails of the elevator shaft. It's not a pleasant smell. The modern oil you buy at the supermarket is the same thing, except that it has been further processed to remove the odor and foul taste.Tortoise wrote:Doesn't rancid oil normally taste terrible--almost vomit-inducing?

The food processing empire is built on industrial fats and oils, extracted from corn, soybeans and other seeds. Crude vegetable oil--which is dark, sticky and smelly--is subjected to horrendous processing to produce clean-looking cooking oils, margarine, shortening and spreads. The steps involved in processing usually include degumming, bleaching, deodorizing, filtering and removing saturates to make the oils more liquid.[17] In the process, the nutrients and antioxidants disappear--but not the pesticides. Most processors also add a hexane solvent in order to squeeze the very last drop of oil out of the seeds. Caustic refining, the most widely used process for oil refining, involves adding very alkaline, chemicals to the oil.
In order to make a solid fat out of liquid oil, manufacturers subject the oils to a process called partial hydrogenation. The oil is extracted under high temperature and pressure, and the remaining fraction of oil is removed with hexane solvents. Manufacturers then steam clean the oils, a process that removes all the vitamins and all the antioxidants—but, of course, the solvents and the pesticides remain. These oils are mixed with a nickel catalyst and then, under high temperature and pressure, they are flooded with hydrogen gas. What goes into the reactor is a liquid oil; what comes out of that reactor is a smelly mass resembling grey cottage cheese. Emulsifiers are mixed in to smooth out the lumps, and the oil is then steam cleaned once more, to get rid of the horrible smell. The next step is bleaching, to get rid of the grey color. At this point, the product can be called "pure vegetable shortening." To make margarines and spreads, artificial flavors and synthetic vitamins are added. But the government does not allow the industry to add synthetic color to margarine--they must add a natural color, such as annatto--a comforting thought. The margarine or spread is then packaged in blocks and tubs and advertised as a health food.

Either way, it would be bad. Rancidity is a sign that the molecules have degraded and started to release free radicals. If you heat that unstable oil even more — or expose it to more air or light — it just causes even more degradation. "Taste" is the least of your worries when using a rancid oil.Tortoise wrote:Maybe that means oils don't have to be either completely rancid or completely non-rancid, but can be intermediate between the two as the rancidity progresses?

When an oil breaks down, bits and pieces of its molecules break off and become unpaired electrons (i.e. free radicals) in your body (and your bloodstream). Saturated fat molecules are very straight chains of carbon — allowing the molecules to pack up against each other at room temperature — which is why they appear solid at room temperature. They are very strong and can withstand breakdown better than monounsaturated fats, which have a large bend in the middle of their molecules. Polyunsaturated molecules are so complex that the molecules can barely get close together, so they are liquid at room temperature. These complex molecules are much more fragile and the unpaired electrons are easily released — particularly during the high-heat, highly-oxidized manufacturing process outlined above.Tortoise wrote:And when you say an oil "breaks down," what is it breaking down into?
Saturated fat is the type of fat found in such foods as lard, butter and coconut oil. Saturated fat molecules are straight, so they pack together easily. That is why saturated fats are solid at room temperature. Unsaturated fats have a little bend at each double bond, with two hydrogen atoms sticking out on the same side. And when that molecule gets incorporated into your cells, the body wants those two hydrogen atoms to be on the same side of the carbon chain, forming an electron cloud; that is where controlled chemical interactions take place.
During the process of partial hydrogenation, one of those hydrogen atoms is moved to the other side, causing the molecule to straighten out so that it behaves chemically like a saturate—although biochemically it behaves very differently. The original, unsaturated molecule is called a “cis”? fatty acid, because the two hydrogens are together, and then it becomes a trans fatty acid, because the two hydrogens are across from each other ("trans" means "across"). Your body doesn’t know that this new molecule is something that has never existed in nature before, and when you eat one of these trans fatty acids, it gets built into your cell membranes. Because of the chemical rearrangement, the reactions that should happen can’t take place. Enzymes and receptors don't work anymore. The more trans fatty acids that you eat, the more partially hydrogenated your cells become and the more chaos that you are going to have on the cellular level.

All of the margarines, shortenings and even low-trans-fat spreads are made with these harmful ingredients. They're used in chips and crackers, and most restaurants use them for cooking fries. Until the early 1980s, fast food outlets and restaurants cooked the fries in tallow, which is a very safe fat, but now they use partially hydrogenated soybean oil.
In the past, when you made desserts for your kids, at least the sugar they contained came with butter, eggs, cream and nuts—all good wholesome foods. Now manufacturers can imitate the butter, eggs, cream and nuts, so all you have is sugar, industrial oils and artificial ingredients in these instant puddings, pastries and other artificial desserts.
Many diseases have been associated with the consumption of trans fatty acids—heart disease, cancer, and degeneration of joints and tendons. The only reason that we are eating this stuff is because we have been told that the competing saturated fats and oils—butter, lard, coconut oil, palm oil, tallow and suet—are bad for us and cause heart disease. Such assertions are nothing but industry propaganda.

Yes, it will keep longer. But monounsaturated fat — such as olive oil — will become solid in the refrigerator. If it doesn't become solid, that usually means it's not a pure olive oil.Reub wrote: I picked up the Trader Joe's Ca Estate olive oil today. Do you think it would keep longer if it's refrigerated.
LOL, I just tried this yesterday with TJ's CA estate olive oil. I keep my place pretty warm, and I have a history of not using olive oil fast enough. Oh well...Gumby wrote:Yes, it will keep longer.

Reads like sour grapes to me. I'm very cynical about EVOO. Adultered olive oil is epidemic in Italy. Colavita seems more concerned about taste and sensory perceptions than whether the oil is degraded or healthy. Typical consumerism mindset. Might be worth checking out that Fruttato, though. At least the UC Davis study seems to have motivated them to stop using clear bottles.Gumby wrote: Great resource, MG!

Olive Oil Times: Leonardo Colavita and the UC Davis Olive Oil Report
I've also tried this EVOO: http://tinyurl.com/blnvjkc Sounds really great, right? But its on my shit list. I've also tried Bariani several times and while I had no issues with it, I really didn't care for the nonfruity, grassy flavor. I understand they bottle it really early and it should age while sitting though.Personally, I try to look for small batch olive oils that have good taste and smell — and I hope for the best. Many small gourmet food stores will let you taste and smell olive oils before you buy them. Here are some good tips to discerning quality olive oil:
Fish oils going through a similar process. There's only a few "cold process" fish oils on the market and the cost difference and lower amounts of EPA/DHA don't really make it worth it.Gumby wrote: Here is a diagram of the production process for modern refined vegetable oils...
In a case of something like refined canola oil, which still has a significant Omega-6 component, the remaining Omega-6 will break down into essentially what is "pre-partially hydrogenated" rancid molecules just from the high temperature (500F) processing. They are not usually detectable by taste or smell. Canola oil also has acid residues of the kind used in mustard gas during WWI.Tortoise wrote: And when you say an oil "breaks down," what is it breaking down into?
Looks good. I'd quibble with the placement of the Palm Kernel Oil which has a slightly better profile than Coconut Oil and has a lot of antioxidants (giving it a cool red color). An unrefined/rew version can be right up there with raw Avocado oil.Gumby wrote: Perhaps MG can weight in, but this looks like a pretty good chart showing the best/worse oils for different uses...

As mentioned in a previous thread, nuts are pretty toxic — some more than others. They have a lot of phytic acid (and Omega 6) in them, so it's best not to go nuts on nuts...stone wrote: I get vegetable oil as various intact nuts, avocados, whole grains (they have oil) etc. To my mind that is the least processed way to get it and it also looks and tastes great. I'd rather have a sprinkling of cashew nuts in a curry than put liquid oil in. Pine nuts are nice with beef and swede or with tomato, spinach and kidney beans. I cook a lot with a wok not using oil. I guess that goes against tradition but people seem to like the taste of what comes out.
I'm not on a low carb diet though.
I've been using 1/4c each of raw almonds and raw old-fashioned oats in my smoothie for years. I've never noticed an issue unlike a can legumes or a full bowel of oatmeal. But just to be safe, I'm now soaking them for 24 hours before using.
I just chalk it up as another low-level toxin. What pisses me off is the amount of phytic acid in soy-based infant formulas (most infant formulas are, unfortunately, soy-based). Unbelievable.MachineGhost wrote:I'm rather tired of yet another damn thing one must do or don't do when it comes to food and health.
Soy is suppose to contain relatively large amounts of flouride, manganese and phytoestrogens too. Flouride is a neurotoxin and manganese is necessary for MSG -- another neurotoxin -- to be formed in the brain from free glutamate. I couldn't understand how I suddenly became so sensitive to nutritional yeast powder until I realized it probably was my manganese supplement amplifying the negative effects of the MSG in it! When you want to literally kill yourself because of migraine pain, you know something is really toxic beyond a reasonable doubt.Gumby wrote: I just chalk it up as another low-level toxin.

I've now had second thoughts about soaking my little bit of oats and almonds. Because cancer appears to gobble up the phytic acid, I'll just go back to not soaking them. Don't need the guilt on my conscience. I'll leave soaking for bulk beans and meal-sized oatmeal.Gumby wrote: Yes, right... I meant to say anti-nutrients in soy (not just phytic acid).
I don't think there is any real difference between MSG and nutritional yeast powder. It's all in the semantics: http://www.daystarbotanicals.com/nutritionalyeast.htmlIt's funny you should mention the Nutritional Yeast powder. I recently got a package of the Frontier brand because supposedly it isn't produced with (much) heat, thus minimizing the amount of MSG. Supposedly Frontier is one of the few brands tries to avoid MSG. I thought it would be a good way to get all of the B vitamins. Not sure what was in it but I stopped taking it after a few days. It made everything taste terrible and my son was bouncing off the walls. My throat felt very tight. It's in the basement now. Oh well...
That's what I do. I don't eat enough nuts to make a difference one way or the other. It seems the key is to avoid "high" amounts of phytic acid, but moderate amounts are fine (and possibly beneficial). All I know is that pre-soaked oatmeal and legumes feel noticeably better in the stomach and digestive track.MachineGhost wrote:I've now had second thoughts about soaking my little bit of oats and almonds.

Right. I was aware of that. I had just heard that the Frontier brand nutritional yeast was "low-heat" pasteurized, which supposedly minimized the formation of MSG. Still, it's pretty clear that there was still some MSG in it. Too bad they don't publish how much MSG they are dosing you with.MachineGhost wrote:I don't think there is any real difference between MSG and nutritional yeast powder.

Also, all nutritional yeast powder is fortified with synthetic B vitamins. There's just no way you can get the RDA without doing that. So its kind of bunk about nutritional yeast being a "good source of B vitamins" if you had in mind that it would be natural.
