    Excerpt: ... Schweiger, U. et al. (1988). Caloric intake , stress, and menstrual function in athletes. Fertility & Sterility, 49, 447-450. This study investigated the relationship of stress and nutrition to endocrine function in athletes. They compared 18 athletes (minimum 2 years endurance training) and 25 control participants matched in age, age at menarche, BMI, daily caloric intake , % carb/protein/fat. Progesterone (P) and estradiol (E2) were measured from the blood samples collected daily (except on weekends) from both groups for the duration of one menstrual cycle (or for 6 weeks in cases of amenorrhea). All subjects in the control group showed increasing E2 levels that reached a max greater than 120 pg/ml. Only 5 controls had luteal phases that lasted fewer that 8 days. Four athletes did not show increasing E2, indicating no follicular growth, and were excluded from further analysis. The remaining 14 athletes did not differ from controls on longitudinal E2 mean in the follicular phase or on measures of E2 max. Longi ...

    Excerpt: ... erol, and blood cholesterol levels drop Another important note, GI health is improved by fiber in the diet. Taken with adequate fluid, dietary fiber lessens the likelihood of hemorrhoids (swellings in rectal veins), appendicitis (caused by compaction of the stools that lead to appendix obstruction and bacterial infection), and diverticulitis (the formation of bulge-like pouches in the colon wall due to weak intestinal muscles). Summary: Recommended intake of sugar: no more than 10% of the daily caloric intake should be in the form of sugar. Recommended intake of starch: 55-60% of the total caloric intake should come from carbohydrates (1,100 to 1,200 kcal of carbohydrates [275 to 300 grams] for a person consuming 2,000 kcal per day). Recommended intake of fiber: 12.5 grams per 1,000 kcal consumed (25 grams per day for a person on a 2,000-kcal/day diet) is recommended by the FDA. The American Dietetic Association recommends 20 to 35 grams per day. Alternatives to Sugar: Artificial sweeteners are discusse ...

Be clear about any assumption you must make to do the problem. (4 marks) (b) If a father receives 28% of his calories in the form of fat about what percentage should you predict for the son? (5 marks) (c) Suppose we select 36 families at random from this group of 1000 for a more detailed dietary assessment. You may assume that they are selected with replacement so that the selections are independent. What is the chance that the 25 selected fathers have an average between 34 and 36% of their daily dietary calories in the form of fat. (4 marks) (d) In 50 of the families the father received less than 15% of his daily caloric intake in the form of fat. If we eliminate this group of 50 father-son pairs from our study will the correlation coecient go up or down; that is, is the correlation coecient for the other 950 pairs more than 0.4, less than 0.4, or still about 0.4?

Remember, you can use notes and the book, but no calculator. 1. (35 points) A person decides to calibrate caloric intake c(W ) as a function of their weight W . In particular, suppose c(W ) = 3000 5W , and that dW = c(W ) 10W. dt a. If W (0) = 100, nd c(W ). b. If W (0) = 100, is weight increasing or decreasing? c. Find the equilibrium weight for this person. d. Draw a phase-line diagram. e. Sketch the graph of a solution starting from W (0) = 100. 2. (35 points) A more sophisticated dieter allows caloric intake C to follow its own dierential equation. dW = C 10W dt 300 dC = 1. dt 100 + W a. Draw the phase plane, replete with nullclines, equilibria and direction arrows. b. Sketch a solution starting from a small weight and high number of calories. 3.

    Excerpt: ... Sociology 401c Food and Social Inequality Problem Set #2: Global Foods due October 16 1. Select three of the families profiled in Hungry Planet (at least two of these families should live outside the US). Write a short essay that compares the diets of the three families. In your comparison, you should consider the following 1. the quantity of food in the families' diets; 2. what they eat and the variety of food in the families' diet; 3. the nutritional value of their diets; 4. the sources of their (is it local? highly processed?); 5. how food is stored and prepared. You should note both similarities and differences, and I encourage you try to identify patterns or regularities across countries-even if this means drawing on descriptions of other families or other information. 2. From the data table on pages 280-281, generate graphs that show the following relationships: 1. Income and caloric intake 2. Income and meat consumption What patterns do you observe? Are there any outliers? Now select two other pa ...

Any dierence in post-treatment outcomes might be due in part to pre-treatment dierences, rather than the program itself. 4. Externalities will tend to cause an underestimate in the size of the eect of the drug, since some of the bene.ts of the drug will spill over to the control group. 5. As discussed in class, there are 2 pieces of evidence. First, several papers have studied the link between income and caloric intake , and the consensus seems to be that there is a relatively small but signi.cant relationship between the two. Second, papers have studied the relationship between caloric intake and capacity. These have tended to .nd a relatively weak eect. The same is true of studies relating nutrient intake to capacity, like the Thomas et al. (2006) study in Indonesia. 6. The consensus in the literature is that informal risk-coping and consumption smoothing mechanisms are lar ...
