The importance of food systems and the environment for nutrition
Jessica Fanzo, Alexandra L Bellows, Marie L Spiker, Andrew L Thorne-Lyman, Martin W Bloem

Volume 113, Issue 1, January 2021, Pages 7–16
Global and local food system transformation is necessary in order to ensure the delivery of healthy, safe, and nutritious foods in both sustainable and equitable ways. Food systems are complex entities that affect diets, human health, and a range of other outcomes including economic growth, natural resource and environmental resiliency, and sociocultural factors. However, food systems contribute to and are vulnerable to ongoing climate and environmental changes that threaten their sustainability. Although there has been increased focus on this topic in recent years, many gaps in our knowledge persist on the relation between environmental factors, food systems, and nutritional outcomes. In this article, we summarize this emerging field and describe what innovative nutrition research is needed in order to bring about food policy changes in the era of climate disruption and environmental degradation.
Higher eating frequency is associated with lower adiposity and robust circadian rhythms: a cross-sectional study
Mar?a Fernanda Zer?n-Rugerio, Antoni D?ez-Noguera, Maria Izquierdo-Pulido, Trinitat Cambras
doi : 10.1093/ajcn/nqaa282
Volume 113, Issue 1, January 2021, Pages 17–27
Although overweight and obesity are assumed to arise from an energy imbalance, evidence has shown that the frequency and timing of meals are also potential risk factors for obesity. However, the lack of a consistent approach to define eating patterns relative to internal circadian rhythms limits the extent of these findings.
Replacing white rice bars with peanuts as snacks in the habitual diet improves metabolic syndrome risk among Chinese adults: a randomized controlled trial
Di Wang, Liang Sun, Xiaoran Liu, Zhenhua Niu, Shuangshuang Chen ...
doi : 10.1093/ajcn/nqaa307
Volume 113, Issue 1, January 2021, Pages 28–35
Observational studies have suggested that intake of nuts is associated with lower risk of cardiometabolic diseases, whereas refined grain consumption has been linked to higher risk. Little is known about whether substituting white rice, a refined grain, with nuts may confer benefit among adults at high risk of cardiometabolic diseases.
Dietary pattern trajectories across adolescence and early adulthood and their associations with childhood and parental factors
Geeta Appannah, Kevin Murray, Gina Trapp, Michael Dymock, Wendy Hazel Oddy ...
doi : 10.1093/ajcn/nqaa281
Volume 113, Issue 1, January 2021, Pages 36–46
Although adolescent dietary patterns tend to be of poor quality, it is unclear whether dietary patterns established in adolescence persist into adulthood.
Inflammation correction in micronutrient deficiency with censored inflammatory biomarkers
Santu Ghosh, Anura V Kurpad, Harshpal S Sachdev, Tinku Thomas
doi : 10.1093/ajcn/nqaa285
Volume 113, Issue 1, January 2021, Pages 47–54
Biomarkers of micronutrient status vary with inflammation, and can be corrected by a regression-based approach [Biomarkers Reflecting Inflammation and Nutritional Determinants of Anemia (BRINDA)] using measured concentrations of inflammation biomarkers, e.g., C-reactive protein (CRP) and/or ?1-acid-glycoprotein (AGP). However, this is confounded when inflammation is measured with multiple assays with variable limits of detection (LOD) and lower limits of quantification (LLOQ).

Beshada R Jima, Hamid Y Hassen, Yalemwork Getnet, Paluku Bahwere, Seifu H Gebreyesus
doi : 10.1093/ajcn/nqaa294
Volume 113, Issue 1, January 2021, Pages 55–62
Midupper arm circumference (MUAC) is used as an independent diagnostic tool to detect wasting in children aged 6–59 mo. However, little is known about the diagnostic performance of MUAC for detecting wasting among infants aged 1–6 mo.

doi : 10.1093/ajcn/nqaa274
Volume 113, Issue 1, January 2021, Pages 70–82
Whey protein and zein are of nutritional interest due to their high leucine content, but little data are available on their amino acid (AA) ileal digestibility.
Vitamin D in human serum and adipose tissue after supplementation
Cora M Best, Devon V Riley, Thomas J Laha, Hannah Pflaum, Leila R Zelnick ...
doi : 10.1093/ajcn/nqaa295
Volume 113, Issue 1, January 2021, Pages 83–91
Serum 25-hydroxyvitamin D [25(OH)D] concentration is an indicator of vitamin D exposure, but it is also influenced by clinical characteristics that affect 25(OH)D production and clearance. Vitamin D is the precursor to 25(OH)D but is analytically challenging to measure in biological specimens.

doi : 10.1093/ajcn/nqaa273
Volume 113, Issue 1, January 2021, Pages 104–112
Vitamin D deficiency is associated with obesity-related conditions, but the role of early life vitamin D status on the development of obesity is poorly understood.
Longitudinal associations of modifiable risk factors in the first 1000 days with weight status and metabolic risk in early adolescence
Jiajin Hu, Izzuddin M Aris, Pi-I D Lin, Sheryl L Rifas-Shiman, Wei Perng ...
doi : 10.1093/ajcn/nqaa297
Volume 113, Issue 1, January 2021, Pages 113–122
Many studies have identified early-life risk factors for childhood overweight/obesity (OwOb), but few have evaluated how they combine to influence later cardiometabolic health.
Revisiting the critical weight hypothesis for regulation of pubertal timing in boys
Maria Bygdell, Jenny M Kindblom, John-Olov Jansson, Claes Ohlsson
doi : 10.1093/ajcn/nqaa304
Volume 113, Issue 1, January 2021, Pages 123–128
Recent findings indicate that there is a body weight–sensing homeostatic regulation of body weight in postpubertal rodents and humans. It is possible that body weight sensing also might be involved in the regulation of pubertal timing. Although an early small study suggested that there is a critical body weight for pubertal timing in girls, most studies have focused on BMI and reported an inverse association between BMI and pubertal timing.
The obesity paradox for mid- and long-term mortality in older cancer patients: a prospective multicenter cohort study
Claudia Martinez-Tapia, Thomas Diot, Nadia Oubaya, Elena Paillaud, Johanne Poisson ...
doi : 10.1093/ajcn/nqaa238
Volume 113, Issue 1, January 2021, Pages 129–141
Overweight and obesity are associated with adverse health outcomes. However, substantial literature suggests that they are associated with longer survival among older people. This “obesity paradox” remains controversial. In the context of cancer, the association between overweight/obesity and mortality is complicated by concomitant weight loss (WL). Sex differences in the relation between BMI (in kg/m2) and survival have also been observed.

The Asia-Pacific obesity classification recommends using lower BMI cutoffs in Asians compared with those in Western populations. However, the supporting evidence is scarce and little is known about the exact shape of the relations between adiposity and mortality in Asians.
Late eating is associated with cardiometabolic risk traits, obesogenic behaviors, and impaired weight loss

Tahani Boumenna, Tammy M Scott, Jong-Soo Lee, Natalia Palacios, Katherine L Tucker
doi : 10.1093/ajcn/nqaa293
Volume 113, Issue 1, January 2021, Pages 179–186
There is evidence that low plasma vitamin B-12 and folate individually, as well as an imbalance of high folic acid and low vitamin B-12 status, may be associated with lower cognitive function.
Higher habitual flavonoid intakes are associated with a lower risk of peripheral artery disease hospitalizations
Nicola P Bondonno, Kevin Murray, Aedin Cassidy, Catherine P Bondonno, Joshua R Lewis ...
doi : 10.1093/ajcn/nqaa300
Volume 113, Issue 1, January 2021, Pages 187–199
The role of nutrition in the primary prevention of peripheral artery disease (PAD), the third leading cause of atherosclerotic cardiovascular disease, is undetermined. Flavonoids may attenuate atherosclerosis and therefore persons who consume flavonoid-rich foods may have a lower risk of developing PAD.

Volume 113, Issue 1, January 2021, Pages 221–231
Vitamin A deficiency is a public health problem in sub-Saharan Africa. Pro-vitamin A biofortified (yellow) cassava has the potential to contribute significantly to improve vitamin A status, especially in populations that are difficult to reach with other strategies.
