Trans fats
Hydrogenated
Vegetable Oil (or trans fats)
Hydrogenated
vegetable oils are created through a process in which hydrogen is added to
vegetable oil to make a longer-lasting, solid fat form. Companies use
hydrogenated oil in foods because they give food a desirable texture and taste
and help them last a long time. As a rich source of trans fats, or trans fatty
acids, hydrogenated vegetable oil can increase your LDL, or "bad,"
cholesterol; lower your HDL, or "good," cholesterol; and increase
your risk for heart attack and stroke. The American Heart Association recommends
limiting trans fats to less than 1 percent of your total daily calories or
roughly 20 calories within a 2,000 calorie-per-day diet. Common sources include
stick margarine, shortening and commercially prepared pastries, french fries,
cakes, crackers, cookies, frosting and other foods that list hydrogenated
vegetable oil as an ingredient.
1.
What is a hydrogenated vegetable oil?
2.
What is it used for?
3.
Why is it a bad ingredient?
4.
Name some foods where is easy to find hydrogenated vegetable oil.
Find out your dominant hemisphere.
Recall what we said about the Brain
Myth #2: A person's personality displays a right -brain or left -brain
dominance. Fact: The two sides
are intricately co- dependent.
This myth holds that a right -brain person is generally creative, intuitive, artsy, while a left -brain person is more of a problem -solver, more linear, logical. The myth arose from genuine science, but new imaging technology has shown that the brain is more interdep endent than once thought. The myth probably took root in the 1800s, when scientists discovered that an injury to one side of the brain often cause d a loss of specific abilities. For example, spatial abilities seemed to reside in the right side of the brain, with language in the left. The myth gained ground in the 1960s, when scientists studied epilepsy patients who had surgery to sever the connection between the two hemispheres.
But more recently, brain scan technology has revealed that the hemispheres' roles are not quite so cut - and- dried as once thought. The two hemispheres are in fact highly complementary. For example, language processing, once believed to be left - hemisphere- only, is now understood to take place in both hemispheres: the left side processes grammar and pronunciation while the right processes intonation.
What remains true is that t he right side of the brain controls the left side of the body and vice versa.
Take this test to find your dominant hemisphere. Do you agree with the result?
