so im always reading about how fried food are bad. I agree with the statement, "all deep fried foods are bad" but calling pan fried foods bad confuses me. If i cook chicken breast on a frying pan with some olive oil, i think that's pretty healthy.
so when people refer to fried foods im assuming they mean deep fried?

Itt's bad for you because the oil turns to trans fat. They are both terrible for you(pan frying and deep frying). only difference is that deep frying is obviously worse. It;s like saying which is worse getting stabbed or getting shot? and then saying Getting stabbed is NOT AS BAD, therefore, it is good to be stabbed. That is the logic you jsut used. start sauteeing your food food in butter instead of oil.

Trans fats are molecules that are double binded together, leaving less room for them to bond with hydrogen, which makes them unsaturated. They raise levels of bad cholesterol and lower levels of good cholesterol. Olive oil is good and has many healthy benefits, while transfat has no health benefits. There is no way that olive oil turns into transfat, it is molecularly impossible.
To answer your question, sure it is better to pan fry something in olive oil compared to deep frying, but you're still better off just grilling or baking the chicken though.

i have actually heard that too.. that olive oil becomes trans fat when cooked at high temperatures.. which is why they say to avoid cooking with extra virgin olive oil.. because it has a low smoke point.. but i have no idea if thats true
The best way to cook chicken in my opinion is to boil it, or to roast it.. grilling is also a good option. I swear all 3 taste better than pan frying and use no oil

Only unsaturated fats can be trans fats. Saturated fatty acids are never trans fats because they have no double bonds, and therefore cannot display a trans- configuration. Moreover, lipids containing a triple bond (but no double bonds) cannot be trans fats because a triple bond can only assume one configuration.
Carbon atoms are tetravalent, forming four covalent bonds with other atoms, while hydrogen atoms bond with only one other atom. In saturated fatty acids, each carbon atom is connected to its two neighbour carbon atoms as well as two hydrogen atoms. In unsaturated fatty acids the carbon atoms that are missing a hydrogen atom are joined by double bonds rather than single bonds so that each carbon atom participates in four bonds.
Wilhelm Normann patented the hydrogenation of liquid oils in 1902
Hydrogenation of an unsaturated fatty acid refers to the addition of hydrogen atoms to the acid, causing double bonds to become single ones as carbon atoms acquire new hydrogen partners (to maintain four bonds per carbon atom). Full hydrogenation results in a molecule containing the maximum amount of hydrogen (in other words the conversion of an unsaturated fatty acid into a saturated one). Partial hydrogenation results in the addition of hydrogen atoms at some of the empty positions, with a corresponding reduction in the number of double bonds. Commercial hydrogenation is typically partial in order to obtain a malleable mixture of fats that is solid at room temperature, but melts upon baking (or consumption).
In most naturally occurring unsaturated fatty acids, the hydrogen atoms are on the same side of the double bonds of the carbon chain (cis configuration — meaning "on the same side" in Latin). However, partial hydrogenation reconfigures most of the double bonds that do not become chemically saturated, twisting them so that the hydrogen atoms end up on different sides of the chain. This type of configuration is called trans, which means "across" in Latin.[24] The trans conformation is the lower energy form, and is favored when catalytically equilibriated as a side reaction in hydrogenation.
The same molecule, containing the same number of atoms, with a double bond in the same location, can be either a trans or a cis fatty acid depending on the conformation of the double bond. For example, oleic acid and elaidic acid are both unsaturated fatty acids with the chemical formula C9H17C9H17O2.[25] They both have a double bond located midway along the carbon chain. It is the conformation of this bond that sets them apart. The conformation has implications for the physical-chemical properties of the molecule. The trans configuration is straighter, while the cis configuration is noticeably kinked as can be seen from the following three-dimensional representation.
The trans fatty acid elaidic acid has different chemical and physical properties owing to the slightly different bond configuration. Notably, it has a much higher melting point, 45 ?C rather than oleic acid's 13.4 ?C, due to the ability of the trans molecules to pack more tightly, forming a solid that is more difficult to break apart.[25] This notably means that it is a solid at human body temperatures.
In food production, the goal is not to simply change the configuration of double bonds while maintaining the same ratios of hydrogen to carbon. Instead, the goal is to decrease the number of double bonds and increase the amount of hydrogen in the fatty acid. This changes the consistency of the fatty acid and makes it less prone to rancidity (in which free radicals attack double bonds). Production of trans fatty acids is therefore a side-effect of partial hydrogenation.
Catalytic partial hydrogenation necessarily produces trans-fats, because of the reaction mechanism. In the first reaction step, one hydrogen is added, with the other, coordinatively unsaturated, carbon being attached to the catalyst. The second step is the addition of hydrogen to the remaining carbon, producing a saturated fatty acid. The first step is reversible, such that the hydrogen is readsorbed on the catalyst and the double bond is re-formed. Unfortunately, the intermediate with only one hydrogen added contains no double bond, and can freely rotate. Thus, the double bond can re-form as either cis and trans, of which trans is favored, regardless the starting material. Complete hydrogenation also hydrogenates any produced trans fats to give saturated fats.

The trans fat scare is a little confusing. Trans fats are just fats with trans isomer fatty acids. Yes olive oil contains oleic acid which is a trans fat but CLA also falls into the trans fat cat and so does stearic acid (found in animal fats). What you should be worring about is a specific type of trans fat which contains artificial trans fats, specifically (and I'm sure you've heard this term) partially hydrogenated oils or fats. This is the bad stuff. This is what you need to look out for.

im still trying to grasp how overheating oil olive is a bad thing? and if you use a non-stick pan with a very small amout of olive it should not even be close to how much oil get sucked up during deep frying.
i dont see how olive oil having a low smoke/burning point can effect how healthy the oil is

Hmmm this interests me because last night for the first time I put extra olive oil in a frying pan and fried chicken breasts with some white flower (very little) and some seasoning. I was wondering if this is worse than grilling it. I know the white flower is bad I bet it was 1 tbsp between 2 pieces.

If you are worried about the smoke point of olive oil, try peanut oil. Or, if you still want to use olive oil, add just a little butter to it, that will increase the smoke point.
Really, though, I saute chicken breasts all the time in olive oil and smoke point is not an issue. I would recommend that you flatten each breast to 1/4" before cooking to speed up cooking time and prevent the oil from being used too quickly.

My understanding is, like most things, cooking something can change it's molecular structure. As it was pointed each oil has it's respective change points, olive oil starts to smoke at 190 degrees (not a good deep frying oil). Though to the respective the molecular changes, I haven't a clue. Maybe a google search will show something someone has posted.
Although the structure may change, I don't think you can 'accidentally' make trans or saturated fatty acids at home heating olive or any other oil. That process is a little more involved that just heating.
