                         Types of Fat




                   Trans fats
                                                 Hydrogenation  is  a  process  which
     When vegetable oils are hydrogenated or     liquid  vegetable  are  converted  into
     toughened to make them more stable and      solid fat (such as margarine) by heat,
     long-lasting, trans fat is created. It raises  hydrogen  and  certain  metal  of
     low  density  lipoprotein  (LDL,  or  "bad"  catalysts
     cholesterol)  levels  while  lowering  high       Saturated fats
     density  lipoprotein  (HDL,  or  "good"      Saturated fats usually solid
     cholesterol) levels, raising the risk of heart  at room temperature
     disease  and  stroke.  Cookies,  pastries,
     and  deep-fried  foods  are  all  sources  of
     trans fat in everyday life.
