...saturated fats carry a full quota of hydrogen atoms in their chemical structure, and unsaturated fats do not). Such products as tallow, lard and butter are saturated fats, whereas those like soybean, canola, olive, cottonseed, corn and other vegetable oils are unsaturated. Saturated fats are associated with increases in LDL cholesterol (the bad kind); unsaturated fats can bring that number down...
...however, the result was quite the opposite. That's because hydrogenated fats contain a kind of hydrogen bond called trans that is as bad as the hydrogen bond in saturated fats--maybe even worse, according to CNN dietitian Liz Weiss, an expert on family nutrition. While saturated fats raise ldl cholesterol, Weiss explains, "trans fats appear to both raise bad (LDL) cholesterol and lower the good (HDL) cholesterol." The FDA does not currently require vendors to label foods for trans-fatty-acid content, but the agency has new rules in the works that would force McDonald's and others...
Fats too are gaining new respect. Olives, nuts, avocados and other foods that are rich in mono- and polyunsaturated fat belong in our diets, many nutritionists believe. Not only do these good fats help lower the level of LDL, or bad, cholesterol, but they are also essential for the absorption of fat-soluble vitamins like...
...when natural estrogens stop flowing after menopause, women's risk quickly catches up to men's. Clearly estrogen has some kind of positive influence. And sure enough, a number of studies in the 1980s showed that women who took the hormone at menopause had lower levels of LDL cholesterol, the so-called bad cholesterol, and higher levels of HDL, the so-called good cholesterol, than those who didn't. The benefits of supplemental estrogen couldn't be more obvious...
...salmon's health benefits. Algae boast a special kind of fat, known as omega-3 fatty acids, that seems to help the heart. Omega-3s prevent platelets in the blood from clumping together and sticking to arterial walls in the form of plaque. They also drive down triglycerides and LDL (bad) cholesterol. Researchers suspect that omega-3s may block the production of inflammatory substances linked to autoimmune diseases like rheumatoid arthritis and lupus. Even more tantalizing, preliminary reports suggest that omega-3s interact with the fatty layers that surround brain cells and, as fishy as it sounds, may somehow help...
