Imagine eating everything delicious you want with none of the fat. That would be great, wouldn’t it? uz2s- ,
New “fake fat” products appeared on store shelves in the United States recently, but not everyone is happy about it. Makers of the products, tcdn"]#U
which contain a compound called olestra, say food manufacturers can now eliminate fat from certain foods, Critics, however, say that the new +g7nM7,1a
compound can rob the body of essential vitamins and nutrients and can also cause unpleasant side effects in some people. So it is up to consumers gBS#Z.
to decide whether the new fat-free products taste good enough to keep eating. !rqR]nd
Chemists discovered olestra in the late 1960s, when they were searching for a fat that could be digested by infants more easily. Instead of
lTd2~_
finding the desired fat, the researchers created a fat that can’t be digested at all. J7] 60H#P

Normally, special chemicals in the intestines “grab” molecules of regular fat and break them down so they can be used by the body. A |dzF>8< )
molecule of regular fat is made up of three molecules of substances called fatty acids. ASU\O3%%
The fatty acids are absorbed by the intestines and bring with them the essential vitamins A, D, E and K. When fat molecules are present in YGmdiY:;1
the intestines with any of those vitamins, the vitamins attach to the molecules and are carried into the bloodstream. 6(^9D_"@
Olestra, which is made from six to eight molecules of fatty acids, is too large for the intestines to absorb. It just slides through the intestines <vuX "

without being broken down. Manufacturers say it’s that ability to slide unchanged through the intestines that makes olestra so valuable as a fat w[G_ w:$a
substitute. It provides consumers with the taste of regular fat without any bad effects on the body. But critics say olestra can prevent vitamins A, ! HC<aWb
D, E, and K from being absorbed. It can also prevent the absorption of carotenoids, compounds that may reduce the risk of cancer, heart disease, |;-r};
etc. F}DD;K
Manufacturers are adding vitamins A, D, E and K as well as carotenoids to their products now. Even so, some nutritionists are still -d)n0)9
concerned that people might eat unlimited amounts of food made with the fat substitute without worrying about how many calories they are f)P/@rh
consuming. Y6PA\7Y\

Although rarely seen, bats, as compared to other mammals, are quite common. Bats rank second only to rodents in number and diversity )xy6R]_b
of species. Their numbers probably total in the tens of billions. Bats also vary considerably in size-from the tiny Philippine bamboo bat, with a <vDm(-i3
six-inch wingspan and weighing 1/20th of an ounce to the “flying fox” with a wingspan of four or five feet and weight of two pounds. xS1|Z|&
The diet of bats is varied. Most types eat insects, but they also consume blood, pollen, and nectar and fruits. Some eat other vertebrates f*Js= hvO
(animals with backbones) such as fish, lizards, and even other bats. Those that feed on flowers very often server as the primary pollinator of the ze N!*VG
flowers. The insect-consuming forms, quite obviously, are very beneficial. ArK9E!`^
Perhaps the most unusual characteristic of bats is their skilled nocturnal flying ability. This skill is so highly developed that they are Xs@ ^D,
capable of avoiding obstacles even in total darkness. Bats possess a high degree of tactile sense that may help them in avoiding obstacles, but their &y\2:IyA
primary ability to do so is based on their ability to make high-pitched sounds and on their acute hearing ability. _<Yo2,1^
Flying bats were long thought to be silent creatures, but this is now known not to be the case. While in flight, bats are continuously emitting ]5/U}Um
a series of ultrasonic orientation pulses that are inaudible to the human ear. The frequency of the cries of bats, at 50,000 vibrations per second, is MDt?7c
estimated to be two and half times higher than the human ear can hear. V}+;bbUc-
This unique operation, a highly refined type of sonar system, allows the bat to detect rebounding pulses from obstacles near and far in its dC#\ut%l
environment. They system is unique, additionally, in that the bat is capable of sorting through numerous rebounding pulses so as to avoid objects 3>v0W@C
in its immediate path. Rescarchers are attempting to understand this system in hopes that it may reveal how the human brain processes sensory |Eu~=J7@
information. _1Gut"!{\
In the final analysis bats are interesting and amazing; and to contrast to popular legends, they are quite useful and helpful to nature and `wd* &vl
