In brief: Hydrogenated oils

Meats have some transfats, but most are manmade.
Transfats are made by hydrogenating oils, which turns them into solids (shortening). Transfats are used in processed foods b/c they last longer on shelf that way -- cookies/pie crusts/chips/popcorn/donuts/creamer/margarine. They raise LDL (bad) and lower HDL (good) cholesterol, which leads to heart disease. Saturated fats are just as bad!

Keep in mind: LDL, low density lipoproteins, & HDL, high density lipoproteins are NOT cholesterol but complex protein particles which transport all non-water soluble molecules (lipids in medical jargon) around the body in water outside cells. A single LDL particle contains >100 proteins in outer water soluble shell & carries 3,000-6,000 lipid molecules within; a widely varying % are cholesterol.

In brief: Blocks up arteries

Trans fat is what one gets by adding hydrogen to vegetable oil.
The trans fat is more solid, less "oily", and makes junk food more stable for a longer time. Trans fat is bad because it raises a person's bad cholesterol, and lowers his good cholesterol, so it blocks up arteries worse than saturated fats do. Food labels that say "0 grams" trans fat mean "less than half a gram", not necessarily zero!

In brief: Fat not found Nature

The vast majority of c-c bonds in all fats are single, aka saturated (no room for more hydrogen side atoms).
If double bonds (unsaturated) present & converted to single bonds by industrial hydrogenation lacking control: ½ cis, ½ trans. All living cells do cis- see google images ancel keys started & marketed the myth, 1953, that sat. Fats of natural origin unhealthy & helped drive this problem.
