Igneous rocks form when magma or lava cools and hardens into a rock. Magma and lava are rocks that are so hot they move like a liquid. Magma is molten rock that is underground; lava is molten rock that is above the ground â and that is the only difference between them.A common igneous rock is granite.gneous rocks form when magma or lava cools and hardens into a rock.

In partial hydrogenation, the resulting fats are semi-solid at room temperature. In full hydrogenation, the oils become completely solid. The problem with partially hydrogenated oils is that they contain trans fat, which raises LDL (âbadâ) cholesterol, lowers HDL (âgoodâ) cholesterol and has other harmful effects. In contrast, fully hydrogenated oils, in essence, become saturated fatsâbut they contain no trans fat.
Trans fats raise your bad (LDL) cholesterol levels and lower your good (HDL) cholesterol levels. These changes are associated with increased risk of heart disease. Since 2006, the FDA has required trans fat content to be listed on the Nutrition Facts panel of packaged foods.oods from plants that contain saturated fat include coconut, coconut oil, palm oil and palm kernel oil (often called tropical oils) and cocoa butter. For people who need to lower their cholesterol, the American Heart Association recommends reducing saturated fat to no more than 5 to 6 percent of total daily calories.
