5 Step process to
writing this paper
Step 1: Find what you’re interested in and
form a hypothesis
Step 2: Do crosstabs, checking strength of
correlations, and examine alternatives
Step 3: Make Visual Representations of Data
Step 4: Do plenty of research, using reliable
sources
Step 5: Bring it all together in a clear, well
organized, and well written 15 pg. paper

Hypothesis
• General: the better a culture’s nutrition,
the better immune function its people will
have
 Resulting in less pathogen stress
• Specific: a higher consumption of fish as a
local food supply in a society will result in
less pathogen stress
 conversely, a higher consumption of
animal husbandry will result in more
pathogen stress

Research
• Why are these variables
correlated in such a way?
• So far, research has led to an understanding of disease
distribution that is mainly affected by region (distribution
of vectors), and secondly affected by diet and nutrition.
There is a lot information about how nutrition
affects immune function among people in general (i.e.
how fish oils and omega-3 fatty acids promote good
immunity in the body), but NOT how different society’s
nutritional status relates to their pathogen stress.
