Is There a Nutrition-Based Poverty Trap?

Reflection/What I learned: Initially, the discussion topic is undernourishment. The discussion goes on about the "1 billion hungry people in the world estimate" and that number may be based on what BMI or calorie intake is considered to be "undernourished". The discussion then moves to the increase in food price. When the food prices increase on a global scale, it directly effects the people who need the food the most. The rich and middle class can most likely still afford the food, but the poor who struggle to get it in the first place, are now going to have an even more difficult time doing so. The increase in food prices therefore makes the poor poorer, trapping them even further. Creating a nutrition-based poverty trap. The S-shape is then brought back into this, and further explained.
"So if we write it in math, it's like there is income, nutrition is equal tofunction g of income today, because you get your wages, and then you eatsome good meal.And then income tomorrow is a function f of nutrition.That means that income tomorrow is f of g of income today.So this is what makes this S-shape."

The relationship of the S-shape graph then becomes income generated today AND food consumed today.

The "Engel curve" is then discussed. The Engel curve refers to this phenomenon, which is the share of food increase less than proportionally as you become richer. 
Specifics are then discussed about the actual numbers of money spent on food, "luxury foods" (which to me seemed strangely unrelated), "giffen goods", government food subsidies and how it relates and possibly contributes to a nutritional poverty trap, and further examples of how nutrition itself (in a place like India) will contribute to a nutrition-based poverty trap.

How it relates: The "Is there a nutrition-based poverty trap?" section is relatable to the paper I developed in the WFP in multiple ways. Firstly, there could without a doubt be these "nutrition-based poverty traps"occurring in Sudan, and the average income and diets of the average Sudanese person seems to suggest it. These poverty traps could be one more thing or reason why Sudan is suffering on such a large scale, why they have been suffering for so long, and why (no matter how many millions of dollars are given to them) they still are unable to emerge from extreme poverty. It is a possibility that if poverty traps were examined in Sudan and the solutions of poverty traps (if they exist, we haven't learned yet) were implemented in Sudan, this could potentially have a positive effect.
