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 ...

Excerpt: ... s r=0.4. (a) About what percentage of the fathers receive more than 40% of their daily caloric intake in the form of fat? 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?

Excerpt: ... n studies not easy to do IGF-1 receptor heterozygote Wildtype We have the genes for IGF-1 and the IGF-1 receptor In primates, blood IGF-1 levels correlate with energy status Important! Only observed in females Summary In any animal investigated to date, lifespan can be manipulated by changing caloric intake Hormones are involved (IGF-1 particularly important) IGF-1 communicates energy status Animals enter either a high growth/reproduction state or longer lived (and sometimes dormant) IGF-1 evolved in response to caloric restriction 6 What genes are targeted for regulation in caloric restriction? (which are `turned on' and which are `turned off'?) Experiment: Compare gene expression of muscle cells in young vs old mice (it's different!) Compare gene expression of muscle cells in young vs old CR mice How does caloric restriction (CR) affect which genes are being used (some of these will be the ones critical to maintaining the health span)? Genes affected by caloric restriction summ ...

Excerpt: ... o a two carbon compound (called a two-carbon fragment) NAD+ is being reduced to NADH; pyruvic acid is being oxidized, we are obtaining energy Pyruvic Acid is oxidized to an acetyl group CoA is similar to a nucleotide, B vitamins help make them up CoA forms a labile (weak, easily broken) bond with the acetyl group; becomes Acetyl CoA 2 PA 2CO2 + 2NADH + 2 Acetyl CoA (most of the energy is still stored in Acetyl CoA) - Acetyl CoA could go in the citric acid cycle, or could go into the formation of lipids or proteins Surplus of Acetyl CoA will build up body bulk, but if you lower caloric intake reversible reactions will go back and forth c. Citric acid cycle (fig. 8-7) - Aka Kreb Cycle, TCA Cycle (tricarboxylic acid) - Starts with Acetyl CoA from formation Acetyl CoA releases 2 carbons to become CoA Oxaloacetate (4C) becomes citric acid, oxaloacetate is the start and end of the cycle See handout notes Summary of Kreb Cycle 2 Acetyl CoA + 2 oxaloacetate 2 oxaloacetate + 2 ATP + 2FADH2 + 6NADH So far we have ...

Excerpt: ... the control group, prior to the program. (b) Yes, they might. In particular, they will tend to bias the estimates upwards. 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 ...
