Eating behavior is a major lifestyle-related influencing factor of non-communicable chronic diseases (NCDs), particularly overweight/obesity, and metabolism syndrome (MetS). Typically, eating behavior refers not only to dietary patterns but also to nutrient intake. From the public health perspective, population-based evidence regarding healthy eating is of significance for policy developments regarding NCDs prevention.

Eating behavior is time and economic status dependent, which may change as age or/and socio-economic status changes. This occurs not only in developing societies but also in economically settled communities. Therefore, although relationships between eating behaviors (dietary pattern, nutrients intake) and specific NCDs have been examined in different societies, further investigations of population-level associations between eating behavior and NCDs in different subpopulations (general community residents, elders/children, or patients, etc), especially the interaction of eating behavior and other influences (e.g., physical activity) on NCDs, remains of continuing importance. Meanwhile, updating the dietary patterns and nutrient intake levels of different subpopulations is also necessary.

In the Research Topic Volume I, we received and published lots of manuscripts regarding nutrients intake and NCDs, but very few on macro-level dietary patterns and NCDs (particularly no submissions from epidemiological studies on population-level dietary patterns, e.g., assessment of meat, vegetable consumption for specific sub-populations). Therefore, in this Volume II, we still welcome submissions on nutrients and NCDs, but particularly encourage population-level assessment of latest dietary patterns, or/and transition of dietary patterns in different subpopulations.

Specific themes included in this Research Topic are (but not limited to):
• Investigation of specific eating behavior, e.g., red meat, vegetable, vitamin or mineral intake, among general or subpopulations.
• Population-level assessment of latest dietary patterns, or/and transition of dietary patterns in different subpopulations.
• Associations between eating behavior and selected NCDs, especially hypertension, overweight/obesity, and MetS (but not limited to those).
• Interaction between eating behavior and other influencing factors (e.g., physical activity) for NCDs prevention or control.
