Question

Say there's an advertisement for potato chips that are "healthier" because they're made with vegetable oil. What is true and what could be misleading about this commercial?


also, chemical bonds hold atoms together in molecules, and they hold ions together in ionic compounds. What "everyday" things are also bonded or held together?

10 points to whoever can help me out with these 2 questions. =]

Answer 1

the main health difference with the potato chips is saturation. unsaturated lipids are healthier, oils (which are only made by plants) are unsaturated. fats (which are made by animals) are saturated.
the explanation for why unsaturated lipids are healthier is lengthily and i don't really know the whole reason. though i do know the difference between unsaturated and saturated. unsaturated have some double bonds between the carbons, in saturated each carbon in the chain has four single bonds which are filled with hydrogen, rather than just doubling the bonds between carbons.
it is more involved than that but it is complicated biochemistry.
for the second part of the question, everything. absolutely everything is bonded chemically in one way or another. the only things not chemically bonded are individual atoms. the only elements which exist naturally as single atoms are those in group 8/0 of the periodic table. so everything but those gasses.

Answer 2

Hi. Saturated fats (usually animal based) and trans-fats ( usually hydrogenated) are less healthy than poly-unsaturated fats.

Almost any chemical based item (plastic, Teflon, vitamins, etc.) is held together by some kind of bond.
