In addition, researchers can follow the "movement" of plant DNA during the food consumption process to better understand the feeding behavior of insect herbivores.
Watson and Caldwell [55] pointed out that a large number of tradition studies have focused on food-related behaviors, either food-consumption processes during cross-site comparisons or food-rewarded behaviors in experimental procedures.
The food consumption data were processed with the DietPro software, after which they were analyzed with the programs Microsoft Excel, Epi Info, version 6.04, and the Statistical Package for the Social Sciences, version 13.0 (SPSS Inc., Chicago, IL, USA).
Reducing caloric intake, increasing fiber content, increasing consumption of fruits and vegetables, increasing omega 3 fatty acids consumption, increasing the consumption of monounsaturated fats, and decreasing processed food consumption, should be the foundation of a "good diet".
Rather, obesity increases as physical activity decreases and as sugary, fatty, salty processed food consumption increases.
In China for example, processed food consumption increased 3.2-fold from 19.6 kg per capita in 1999 to 63.4 kg in 2013.
Tobacco, alcohol and processed food consumption data were sourced from Euromonitor Passport Global Market Information Database, 2013 edition, covering 1998-2012 with projections to 2017.
It was found that although personal values and orientation have a major influence on the food purchasing and consumption process, vanity, physical health and perceived body image were major factors of influence in the purchasing and consumption decision.
The results of PCR amplification and obtained sequences of ingested plant DNA demonstrated that a researcher can "follow" the plant DNA in the process of food consumption up to 22 h PI and can make conclusions about the feeding behavior of an insect specifically, on the order of ingested plants.
The authors of the latter studies primarily attribute their findings to the importance of insulin signaling during processes related to food consumption and the location of food sources.
