I liked this part:
Alcohol intake had an interesting relationship to weight changes. No significant effect was found among those who increased their intake to one glass of wine a day, but increases in other forms of alcohol were likely to bring added pounds.
It makes me feel better about the glass of wine I had last night. Not that I needed much of an excuse, but its nice to find one :)
Their research method leaves much to be desired:
Every two years, they completed very detailed questionnaires about their eating and other habits and current weight.
How much do you remember about what you ate on July 21, 2010? I couldn't tell you anything about it, honestly. And the way the questionnaire is worded will strongly influence how a meal gets classified.
That said, its still an interesting study. And as someone who is preparing to go into the healthcare industry and who is married to a nurse, its of personal interest to me.
