Retirement and Food Intake

This topic is a departure from what I usually post but what the heck. In "Changes in Nutrient Intake at Retirement," NBER Working Paper No. w24621, 62 Pages, 25 May 2018, NBER reports the following: 

• ...we find that caloric and nutrient intake fall at retirement in numerous cross-sectional datasets. We can reconcile these contrasting results as being due to well-documented differences and improvements in methodologies used to measure food intake.
  
• Second, using longitudinal data, we also find that intake falls at retirement.
  
• Third, we show that a food consumption index used in prior work to capture the relationship between permanent income and foods eaten can severely underestimate the impact of retirement on consumption. We show that a minor methodological revision circumvents this bias and that the revised consumption index falls at retirement.
  
• Finally, while unemployment reduces the consumption index, we find, in contrast to prior work, that the impact of retirement on the consumption index is larger.
  
• Overall, we consistently find that retirement reduces food intake.
