This article concludes that overweight people are more likely to be nutrient deficient. It this from choosing the wrong foods or is there nutrient malabsorption?

Background: Low micronutrient levels observed with increasing adiposity may result from inadequate nutrient intake and/or alterations in nutrient metabolism. Objective: To examine the association between body mass index (BMI) and micronutrient levels among a nationally representative sample of US adults aged >/= 19 years. Design: Using nationally representative cross-sectional data from the National Health and Nutrition Examination Survey III (NHANES III), we examined odds ratios of low micronutrient levels using logistic regression adjusting for covariates. Measurements: Nutritional biomarker levels (as indicated by serum levels of total carotenoids, alpha-carotene, beta-carotene, beta-cryptoxanthin, lutein/zeaxanthin, lycopene, vitamin E, vitamin C, selenium, vitamin A, vitamin D, folate, vitamin B12, and red blood cell folate) among men and nonpregnant women, by BMI category. Results: Overweight and obese adults had higher odds of low levels for a number of nutrients compared with normal-weight adults. Odds of being low in multiple micronutrients was most common among overweight and obese premenopausal women. Conclusion: These findings underscore the need for further assessment of specific micronutrient inadequacies among persons who are overweight or obese. Specifically, research is needed to determine whether these inadequacies are due to insufficient dietary intake, altered metabolic processes, or both.

When we think of malnourished children, we usually picture a child who is very thin with ribs showing. Is it possible that the increase in obesity in all populations, including children, is causing problems from malnutrition? I wonder if children with the highest BMI were at any greater risk?

PURPOSE OF REVIEW: Malnutrition in late infancy and childhood remains a significant public health issue in developing nations as well as for those in transition to an industrialized economy. In addition, in these settings and particularly in developed nations, overweight is becoming a very serious threat to both the immediate and the long-term health of children. In this review, we present recent studies that have examined relationships between childhood undernutrition and three general areas of performance: physical activity, cognition and behavior. RECENT FINDINGS: Malnourished children have been shown to have decreased physical activity and endurance, and poorer cognitive function and school performance. Multiple single micronutrient deficiencies, including vitamin B12, thiamin, niacin, zinc and iron, have been associated with poorer cognitive performance. Behavioral problems, including attention deficits, have also been associated with food insufficiency and malnutrition. SUMMARY: The effects of impaired nutritional status during childhood may have long-standing consequences for the health and performance of children during their adult years.
