Document Summary

If you graph nutrient intake vs the number of people who are actually consuming the nutrient = bell-shaped curve. Estimated average requirement = falls in middle. That"s what the average person is consuming. Add a safety buffer to consume the rda. If you exceed the upper limit can start having problems as well. For some micronutrients ul isn"t that high. Water is the primary component of body you consume many other fluids. A very large percentage of your body mass is water. 50-70% = largely has to do with how much fat and muscle you have. Even if you"re very obese still 50% of your body = water. More important than food can go longer without food than water. If you decrease your body mass by 2% your performance is already adversely affected. When some of nutrients that are lost during processing are re- introduced. The more processed the food the worse the food is.

Dietary standards influence our nutrient status in many ways (ways that you might not yet recognize). The Dietary Reference Intakes include new approaches to using nutrients to achieve optimum health through new terminology. Understanding these terms provides useful information to apply to our decisions about everyday nutrient and food choices.

1. What is the DRI? What are the 4 part of the DRI.

2. DRI are are based on age, sex. What is your requirement for vitamin C, Vitamin E, Iron

3. What is upper limits? Why is this important? What is your upper limit for Vitamin C? Sodium?

1. Formulate Linear Programming Problem (represent mathematically) for Diet Problem given In slides. First define decision variables then write objective function and constraints.

The Diet Problem
In the diet model, a list of available foods is given together with
the nutrient content and the cost per unit weight of each food. A
certain amount of each nutrient is required per day. For example,
here is the data corresponding to a civilization with just two types
of grains (G1 and G2) and three types of nutrients (starch,
proteins, vitamins):

Nutrient content and cost per kg of food.
Starch	Proteins	Vitamins	Cost
G1 G2	5 7	4 2	2 1	0.6 0.35

The requirement per day of starch, proteins and vitamins is 8, 15
and 3 respectively. The problem is to find how much of each food to
consume per day so as to get the required amount per day of each
nutrient at minimal cost.

I am an ESL student. I am doing a research on a new disease. Following is the introduction of our research. It is really important, I will use it to apply for approval and funding.
Because I am an ESL so mistakes are unavoidable. Could you please help me by checking and correcting my grammar, changing some words/sentences and make it more native and smooth ?

"Micronutrient deficiencies can lead to many severe diseases such as anemia, pellagra, osteomalacia or impaired cognitive development. There are more than 2 billion people worldwide affected by micronutrient malnutrition. In Vietnam, regardless of economic growth improvements in recent years, micronutrient deficiencies still remain the major public health problem. Especially, the issue is even more detrimental in ethnic minorities due to their poverty, backward eating habit and insufficient nutritional knowledge.

From April 2011, an idiopathic disease called inflammatory palmoplantar hyperkeratosis (IPPH) syndrome has caused 20 deaths among 300 hospitalized patients in Ba To, a rural district of Quang Ngai province in central Vietnam. Ba To is a remote mountainous district highly populated by ethnic minorities whose main occupations are farming. Most of households had been continuously consuming moldy rice stored in poor conditions from previous harvests. Of the cases known to have died, 62.8% of patients were admitted with malnutrition and wasting syndrome. We hypothesized that micronutrient deficiencies are the risk factors of high incidence of IPPH syndrome in ethnic minorities. Therefore, we aim to study the micronutrient status and the adequacy of micronutrient intake in ethnic minorities. This study also investigates the association of socioeconomic status, lifestyle factors and living environment of ethnic minorities with their micronutrient malnutrition. Subsequently, a research-based community intervention will be conducted to prevent and control outbreak of IPPH syndrome in Ba To district."
