Key for all my notes: YELLOW= Important to know GREEN= Important terms RED= Important numbers Week 3 Notes for Tuesday September 13    : Diabetes Correction (correction from last notes):   15 g if they are burning a low number of calories for snacks. (sedentary)  30 g if they are burning a high number of calories for snacks. (active) Slide 36 Polycystic Ovary Syndrome (PCOS)  The biggest symptom of PCOS is high insulin levels.   Obesity in the central region is linked to PCOS, especially if her hormone levels are off  Genetics does play a factor in this disease.   Common symptoms: irregular period, excessive abdominal fat, high testosterone,  infertility, low HDLs, high triglycerides, hirsutism, acne, polycystic ovaries, etc.  Treatment: increase insulin sensitivity through o Medication (hormone balance) o Exercise (brings hormone levels down for a period of time) o Weight loss (if needed) o Omega 3 fatty acid (chemical messengers (local communicators), inflammation  (could have same effect as ibuprofen), (3 types: ALA (found in plants (walnuts,  chia, flax seed), EPA, DHA (EPA and DHA are more inflammation: important for the brain (found in marine life (clams, shrimp, tuna, trout, salmon)) o Whole grains, fruits, and veggies (regulates blood sugar better  Fiber, antioxidants, phytochemicals  Low glycemic index foods o Overcompensating is bad!!!!! Extra sugar in the blood stream bonds to cells,  disrupting the messages.  Slide 38 Fertilization  2 Nutrients and 1 substance critical for periconception­ Folate, B12, and Coline (good  sources are eggs, legumes and meat).   Epigenetics (methyls and histones on DNA marks the way your DNA is read) When your DNA is not marked properly and read properly, leads to diseases at a young age like  cancer, diabetes, CVD, and Schizophrenia Pregnancy Slide 1­3 Study terms for pregnancy status Slide 4   Gestation: The time the mother is expected to carry the fetus  Term (38­42) weeks  Preterm (before 38 weeks)  Post term (after 42 week)  Slide 5  1  tri­ zygote (needs no extra calories)  2  tri­ embryo (needs increase in calories) rd  3  tri­ fetus (needs increase in calories) Embryo  # of cells doubles every 24 hours  8 weeks: central nervous system, embryonic tail disappears (Remember 15­28 days to  prevent spina bifida) Slide 10 the Placenta  Purposes: o Hormone production o Nutrient and oxygen exchange o Removal of waste o Placenta is so important because it protects the baby from the mother’s immune  system. Placenta uses 30­40% of glucose from mother’s diet. If mom doesn’t get  enough, placenta isn’t as strong.  o Placenta cake­ predators, and nutrients (not a cure for everything, just like liver)  (need to cook it) Slide 11 Changes of Pregnancy  Weight gain  Blood volume and composition (volume increases by 40%)  Cardiovascular function (heart is bigger, pumping more blood)  Gastrointestinal function  Renal function  Metabolism  Immune function  Nutritional requirement Key for all my notes: YELLOW= Important to know GREEN= Important terms RED= Important numbers Week 3 Notes for Thursday September 15    : Sources of Zinc o Shellfish o Darker meat o Light meat o Nuts o Whole grains (cereal) Slide 14 Weight Gain During Pregnancy  Healthy BMI weight gain needs to be: 25­35 lbs Slide 15  Most of the weight gained during pregnancy is gone directly after and in the weeks after  pregnancy. Of the 30 lbs gained, about 7 lbs is fat, and the biggest purpose for it is  preparing your body for lactation.  Slide 17 Water  Pregnant women need water to increase blood volume and fluid volume. The thirst  mechanism is not a good mechanism to rely on because thirst is often mistaken for  hunger. Water delivers calories and nutrients. If women don’t have enough water they  feel tired.  Slide 18 Blood Volume  In a person, the heart pumps blood and the cells take in nutrients and water, but the water  is attracted back to the proteins in your blood. When that person becomes pregnant, the  blood volume increases, but the protein count does not. Therefore the water stays  between the cells, causing edema. Very common, but not a concern.  Slide 19 Cravings  Cravings occur because of changes­ hormone, and senses. Often women won’t want to  eat meat because of the smell, their sense of smell is heightened.  Increased appetite because of increased metabolism.   One concern with this is that women reach for comfort foods high in fat. Slide 20­22 Mercury and foods to avoid  Mines, coal plants, and other industrial institutions leak mercury that settles in water  sources, that krill consume. Avoid eating larger fish with larger amounts of mercury like  Shark, swordfish, tilefish, king mackerel, tuna sushi/ Bluefin tuna/canned tuna, orange  rough, pike, halibut and limit walleye and bass. (this is the recommendation for  pregnancy, lactation, elderly. Tuna is right on the line, canned tuna is supposed to be safe. We need Omega 3 and tuna is a good source, so we have a dilemma.   If looking for a supplement for Omega 3, look for Krill Oil because of the low amounts  of mercury.   Avoid raw oysters, raw meat, raw eggs, unpasteurized cheese/ milk (soft, blue­veined,  brie, feta, camembert, goat cheese), cold meat spreads, lunch meats (unless handled well), processed meats (unless served steaming hot, well cooked and handled) Slide 24 Toxoplasmosis  Avoid undercooked meat  Avoid unpasteurized goats milk  Wash all raw fruits/vegetables, especially homegrown (water or store bought citric acid)  WASH YOUR HANDS  Cats o Don’t change the cat litter. Make someone else do it or where gloves o Keep cat indoors and don’t give them undercooked meat because they pick up  bacteria o Wear gloves when gardening
