The popcorn itself is not fattening, but the chemicals and added butter flavoring can be fattening. People who have worked at microwave popcorn factories have come down with lung cancers due to constant inhalations of the fumes from the chemicals. It's best to buy just the kernels, put in brown lunch bag, and cook alone. Raw popcorn is the best!
In plain kernels, no.
In flavored microwave popcorn, some do contain tranfats. The nutrition box on the package will show if it's there.
No.
To some extent, yes. It depends on the popcorn you buy, however. For example, SmartBalance popcorn types generally do not contain trans fats.
Many foods naturally contain trans fats such as dairy and meat products. The process of hydrogenating fats results in the formation of trans fats so products that contain hydrogenated vegetable oil have higher levels of trans fats. If the food label lists hydrogenated oil then the product will contain some level of trans fat.
Trans fats are unsaturated fats which have have same/simlar stucture to saturated fats therefore act as saturated fats. Trans fats are present in foods which contain vegetable fat which has been hydrograted partly to me soild. Pizzas can contain trans fats due to how the fat in the pizza base is made or trans fats naturally found in cheese. Trans fat levels should not go over 2g per person per day therefore having some trans fats is not too bad however you should limit the amount of trans fat you from.
yes
fats and oil food like fry chicken and junk food
No fish oil should not contain trans fats naturally. They can be added later though. Milk is more likely to contain natural trans fat. As much as 2%
Ive never seen that done, i think its best kept on pantry shelf. Microwave popcorn can be stored in the freezer. Some processors of microwave popcorn store their product frozen to extend shelf life and to delay rancidity of the fats and oils. Some sites claim that you get more kernels to pop if it is stored frozen.
There might be miniscule amounts of trans fats in pork, the result of feeding the pig a ration which includes trans fats. Trans fats are normally only produced by hydrogenation.
The Crisco brand now makes several product including oils and shortening. The original Crisco product in the can (shortening) was a fat that was hydrogenated to give it a cream/paste consistency that gave better results in baking. Hydrogenated fats are also called trans fats and health wise are now considered more unhealthy than saturated fats. Crisco and other fats contain carbon, hydrogen, and oxygen. Hydrocarbons contain only hydrogen and carbon in some combination so Crisco is not a hydrocarbon. I know it as shortening, a fatty substance used in bakery products like cake. The more 'oily' it is the more UNsaturated, more 'fatty' says more saturated. Maybe the manifacturers label gives more information than I can (don't know the brand).
Trans fats are hydrogenated unsaturated fats and they are supposed to be the worst fats there are for your health. Unsaturated fats are healthy fats and saturated fats and trans fats are unhealthy fats. Trans fats are often added to processed foods to extend the shelf life. There are no such fats as cis fats. There are certainly cis fatty acids and trans fatty acids and the difference between the two is in the hydrogen atoms positions and one could be regarded as an isomer of the other. All fats are basically triglycerides which means glycerol triesterified with 3 fatty acids.
Saturated fats and trans-fats are solid at room temperature. Polyunsaturated and monounsaturated fats (oils) are liquid at room temperature. Trans-fats are liquid fats that are treated chemically and thermally to mimic saturated fats, usually in a process called hydrogenation. This process in a nutshell (it's a bit more complicated) injects hydrogen into the oils at high temperature and high pressure producing polymers (plastics) from the hydrocarbon molecules in the oils. Most vegetable shortenings are produced this way, shortenings (solid fats) that are not natural saturated fats are trans-fats.
