FINAL EXAM: - Not cumulative - From Chapter 15-25 - Write answers on exam booklet as well HLTB03- LECTURE 12 April 06,2011 Current Issues and International Health Readings: Chapters 24 & 25. Benefits of maple syrup: - maple syrup has polyphenols work to inhibit the enzymes that are involved in the conversion of carbohydrates to sugar - has a wide variety of polyphenols; the research team identified 54 compounds in maple syrup - Canadian syrup is 100% pure, non-refined natural product - advisory panel to the US food and drug administration has recommended that the US food and drug administration should do further research into the link between food colouring and childhood hyperactivity - they are not recommending that these products that contain dyes should have packaged warnings - another debate in news is if whether we should continue to have fluorinated water ; Toronto health voted on Monday to continue adding fluoride to our city water it was a 4 hours debate, many representatives present fluoride was first added in 1963 to our water in Toronto: added as a way to prevent tooth decay; add 0.6 mg fluoride per litre - was a concern at this meeting that if people would push to eliminate the fluoride from the water, then we would have a problem about tooth decay as fluorinated water reduced tooth decay by 20 40% - such people questioned if fluoride in water really helps to prevent cavities worried that there is a toxic effect - If we drink too much fluorinated water, we could be susceptible to brittle bones leading to fractures: condition known as skeletal flourosis - The Q is how much water causes this? Around 67 glasses per day would cause this; thus, we dont have to worry - is there fluoride in bottled water? - need to protect us from radioactivity which is coming from Japan (traces can show up in the food we consume) - The amount of radiation in the food supply from Japan is very small compared to what we would get from natural sources everyday - very low levels of radiation are being found in the milk in California and Washington state, but this iodine 131 (type that was found) is apparently short-lived and decays very quickly and as a result harmless; we are in more risk of radiation from the right radon that occurs naturally in the air or from radon that is found in cosmic rays - Naturally have radons: bananas, carrots, red meat - In the US, milk, rainfall, and drink water is tested every 3 months; since the Tsunami in Japan, the environmental protection agency has started testing more frequently - Here in Canada, we are reassured that even though they found radioactivity in rainwater, it wont affect our health
