Last Lecture HLTB03 Lecture 11  When it comes to eating good food, maple syrup has the same compounds as other kinds of super foods (blueberries, green tea, and flax seeds) o The compounds in maple syrup may help keep blood sugar levels in check—has polyphenols—which work to inhibit enzymes that are involved in carbohydrate conversion to sugar o Maple syrup has a wide variety of polyphenols, the research team identified 54 compounds in maple syrup o Maple syrup is 100% pure in Canada; it is a non-refined natural product  An advisory panel to the USA Food and Drug Administration (FDA) has recommended that the US food and drug administration should do further research into the link between food coloring and childhood hyper-activity o They think there’s a link between food coloring and hyperactivity, however, they are not recommending that these products that contain the dyes should have packaged warnings  Should we continue to have fluorinated water? o Toronto’s board of health voted on Monday to continue adding fluoride to our city water o In Toronto, fluoride was first added to our water in 1963—added as a way to prevent tooth decay—adding 0.6 milligrams to fluoride per liter is within accepted range o There was a concern at the meeting that if people removed the fluoride from water, there would be an increase in tooth decay as fluoride reduces tooth decay by 20-40% o People that were opposed to keeping fluoride in the water questioned whether fluoride actually prevented cavities—also said there may be a toxic effect o If we drink too much fluoride in our water, we could be susceptible to brittle bones leading to fractures and skeletal fluorosis o How much is too much fluoride water?  We would have to drink on average 67 glasses of fluoride water per day to be at risk of skeletal fluorosis o The opponents of fluoride water also raised the question of having lead  Because fluorinating water involves lead  Government in Ontario does not fund dental care for our teeth  Radioactivity coming from Japan? We are worried about radioactivity that could show up in the foods that we eat o We are being told that the amount of radiation on the food supply from Japan is very small o Very low levels of radiation are being found in the milk at California and Washington state but apparently the iodine 131 (radioactive) is short lived and decays very quickly and we are being told it is harmless o In fact, we are more at risk of radiation that occurs naturally in the air or from the radon which we can get from cosmic rays in our atmosphere  There are foods that we eat everyday that have low levels of naturally occurring radioactive material o bananas, carrots, red meat  In the US, the Environmental Protection Agency normally tests milk, rainfall, and drinking water every three months o Began testing more frequently since earthquake in Japan o Banned imports of dairy and produce from Japan o Seafood still being sold, but said to be safe  Here in Canada, we are being reassured that even though they found radioactive iodine levels in seaweed in BC, does not pose a threat to health thus not to worry  Closer to home, a case of TB was found at St. Maria Goretti Catholic Elementary in Scarborough o Other parents were informed of the possibility that their child needs to be tested because a child has tested positive—anyone who has had casual contact does not require testing but anyone with close contact should be tested  Classic symptoms of TB are: o Cough lasting longer than 3 weeks; o Fever; o Night sweats; o Fatigue; and o Weight loss  Immunization is the first key to prevention, second key is to report symptoms  Ontario is going to be increasing health care spending to 48 billion dollars o However hospitals are going to be receiving the same increase that they received last year, which was 1.5 % increase from year before o We are being told that an extra 15 million dollars will be invested in the next 3 years in order to expand programs for breast screening exams to target women ages 30-49 because of pre-existing or medial gene in their family o 50-69 will be included as well for screening o An additional investment of 93 million dollars for the mental health and addiction strategy for children and youth o As well an extra 100 million dollars a year for more pharmacy services for people covered under Ontario drug benefit program, o The community services sector will get an extra 3% funding—community homecare services, nursing services in the community  Every year, Canadian Blood Services supplies enough blood for 600,000 transfusions for a wide range of medical conditions  In the 70s and 80s two deadly viruses were introduced into blood supply worldwide—Hep C and HIV o Hepatitis C: blood-borne disease spread through blood contact with an infected individual  Symptoms  Liver inflammation  Liver cancer  Cirrhosis  Estimates of people infected with transfusion associated Hep-C ranges from b/n 60,000-160,000  90% go on to develop chronic Hep, and from these, 10% will develop cirrhosis or liver cancer after 10 years o HIV: 5-10% affected through blood transfusion
