Cracked Science vid 1:Brian Wansink: -Cornell prof-Smarter lunchrooms movement-His blog post about forcefully finding a conclusion from a data set triggered investigation -150 impossibilities and inconsistencies in 4 out of 5 of his papers-Data detectives -GRIM and GRIMMER: automated the process of looking at mathematic impossibilities-Science corrects itselfCracked science vid 2:Age-related Macular Degeneration-1/25 Canadians -Black blob = Scotoma -Macula: central portion at the back of the eye: -small patch, full of photoreceptors, needed to ensure what we are seeing is right-Beta-carotene vitamin in carrots?-preservision and vitalux: offer a combo platter of vitamins, minerals, and AREDS regimen -Can slow down the progression from intermediate AMD to advanced AMD-Uses lutein and zeaxanthin instead of beta-carotene bc beta-carotene was found to increase the risk of lung cancer. -Not everyone reacts AREDS : pharmacogenetics but really? Topic 1 Lesson 1:1-2Pomegranates have anticancer properties-compounds called aromatase inhibitors -Cannot assume that pomegranate has any effect on humansApricot pits:-Chemical called laetrile, extracted from apricot pits, contain a compound that can release cyanide-People believed it could kill cancer cells but why not other cells?1-3Long time ago: Hippocrates thought-flax was great for the intestines — which is true -Flax has a very very strong laxative effect -Flax seeds contain omega-3 fats— but not as good as the ones that are found in fish-Linked with a variety of beneficial effects including reduction in risk of cardiac arrhythmia -Flax seeds also contain compounds called lignans: estrogen-like properties -Flax seeds contain soluble fiber and insoluble fiber. Fiber is indigestible component of food -Fiber passes through to the colon —> bacterial can manipulate it —> break it down —> some absorbed, some excreted = laxative effect-Soluble fiber can reduce cholesterol-Insoluble fiber speeds substances through the gut and regulating us
-Intake of flax seed, bc of lignans, reduces the risk of breast cancer in pre-menopausal women who are overweight. There are breast cancers that are stimulated by the body’s over-production of estrogen and the lignans block those estrogen receptors. -egg yolks contain a lot of cholesterol, about 300 mg, and high blood levels of cholesterol = heart disease -To compete with the omega-3 fish, the chicken farmers started feeding their chicken flax seeds for “omega-3 eggs” Doughnuts: -trans fat: stable so that the oil doesn’t break down easily. -Raises blood levels of cholesterol Oat bran:-Beta glucan—soluble fibber that lowers cholesterol levels-3 grams of beta glucan a day -1.5 cups of oatmeal 1-4Enzymes: substances, protein molecules, composed of amino acids, tangible, biological catalysts.
