What's the healthiest oil for deep frying?

If there is such a thing? I want to fry fish and French fries. No to olive oil right? Also, olive oil is expensive for frying, no?

        Grapeseed oil is not healthy, IMO.

        The Omega 6 oils, of which grapeseed oil is one, are problematic because they interfere with
        Omega 3 absorption.

        Of course, all the sellers of grapeseed oil would like you to believe otherwise.

        Disclaimer: I was a hired consultant by two grapeseed oil manufacturers to research the chemistry and nutrition issues, and ultimately, to break the bad news to them.

      2. As far as saturated fats, I'm thinking Canola oil is the lowest maybe at 6% or so...It is low cost, and available in almost all retail grocery markets. ~~ That being said, I personally can't stand the stuff...smell nor taste...even though it is said to be a neutral tasting oil. ~~ For deep frying I reach for peanut... sometimes corn, not the healthiest, but it's what I like. ~~ Fried food is really not that bad for you, but bad fried food is.

          I will support your advice to SKIP the canola oil!!!!!!

          1. re: sandylc

            Cannot stand, either, canola oil. Fishy. Even if it doesn't smell fishy, it does when heated, especially when heated to high temps that are well below the smoke point. Vile stuff.

                  and the CANOLA is related to the NAUGA!!

              1. re: maria lorraine

                Does anybody else find this to be true with Canola? I have used it once or twice, and find that it spatters a whole bunch more than any other oil I've ever used.

            1. re: Uncle Bob

              Glad to hear someone else say that about canola oil. It has never tasted neutral to me. It always tastes rancid, even a newly opened bottle. I just can't stand the stuff, and refuse to use it. Maybe some day we'll find out there's a genetic trait to tasting canola oil, kind of like how some people (not me) think cilantro tastes like soap.

              1. re: MelMM

                I used Canola oil because it is cheaper for deep frying. I make a small about 32 oz pot of canola oil and 2 whole garlic and bring to boil until the garlic browned. Let it cool and put it in a jar for cooking. I do not know if healthy or safe. Any comments?!?

                1. re: stbrigid8

                  Not safe, because of the potential for botulism.

              2. re: Uncle Bob

                Are you guys talking about rapeseed oil?
                I must say I have never noticed anything off tasting about that. Are we talking about the same stuff here? I've read several places that it's supposed to be both neutral and healthy. I certainly subscribe to "neutral".

                1. re: Grunde

                  Yes, canola oil is rapeseed oil. It tastes and smells vile, especially when heated. Also, there are plenty of people easily found online who claim that it is NOT healthy for you. From what I have read about it, the rapeseed plant is highly toxic and its oil must be highly processed to make it edible.

                  1. re: sandylc

                    Not exactly. The oil from the original rapeseed plant was ... well, not highly toxic, but high in a compound called erucic acid. The the rape plant was then hybridized by conventional plant breeding techniques to reduce the acid content of the oil (supposedly "canola" comes from "Canadian oil low acid").

                    Since then, however, most strains of canola in North America are GMO. In addition, many people do find the taste offensive.

                    1. re: Ruth Lafler

                      The name canola is from as follows:

                      "The name canola is a contraction of Canada and ola, meaning oil"

                      From the Canola Council of Canada.

              3. What about coconut oil? Thanks for the replies.

                  I'm not an expert, but I think coconut oil's smoke point is too low. I use Rice Bran oil because it has a higher smoke point, and there are health benefits.

                  Do a quick google search, you'll find heaps of info!

                  1. re: ursy_ten

                    Different people worry about different things when they say "healthy." If anyone is worried about added hexane to their diet, Rice Bran Oil is a particular one to avoid. Some Grapeseed Oils are a problem as well, but I've never found a RB Oil that wasn't processed with hexane, where as some Grapeseed Oils are alcohol extracted.

                    1. re: thatwhileifound

                      Thank you - hadn't heard of hexane before. So much you have to look out for, I can't keep up!

                    2. re: ursy_ten

                      'Unrefined' cc oil has a smoke point of 450 F.

                    3. re: LuluTheMagnificent

                      I like coconut oil for frying fish. I just, for the first time, read the entire label on my container of coconut oil and it says do not use for deep frying. But, I've never had a problem with it. I love it for frying chicken as well.

                      The brand I buy is Louana. Nowhere on the package does it say hydrogenated. It stays solid at 76 or below. It does not smell or taste like coconut at all. It acts like Crisco in the frying pan - which means the food doesn't absorb as much oil as corn oil or canola, as long as you have it hot enough. The other oils leave things greasier.

                      As to how healthy it is? Don't know.

                      1. re: LuluTheMagnificent

                        Coconut oil has a pretty high smoke point, actually, but it's quite expensive, IMO, for deep frying. I use peanut, or if I'm really being a cheapskate, corn oil. I don't know if either has any real health benefits, but as I don't deep fry that frequently I don't worry about it too much.

                        1. re: LuluTheMagnificent

                          Unrefined coconut oil is the only oil I use for deep frying. Works great.

                          1. re: LMAshton

                            Not very neutral in flavor. I use it but only in certain applications

                        2. On today's Dr. Oz show, red palm oil was recommended as having a very high smoke point, hence resistant to breaking down into harmful compounts. Never heard of the stuff.

                            Whole Foods sold red palm oil years ago, I haven't checked lately.
