While inflammation is a known beneficial mechanism, pro-inflammatory nutrients can lead to chronic inflammation. The energy-adjusted dietary inflammatory index (E-DII) has revealed positive associations with chronic inflammatory diseases. However, more evidence about the demographic risk factors for high E-DII is needed. Therefore, the present study reviewed the high-risk groups of people for high E-DII scores. Men had higher E-DII than women worldwide, which could be explained by the craving for energy induced by stress and higher physical activity. However, in some societies, women had higher consumption of a pro-inflammatory diet, which could be induced by compulsive eating and craving for more sweets and carbohydrates during menstruation and also can be seen among women with premenopausal syndrome. The pro-inflammatory diets were more common among elders in southern America, East Asia, and Arab countries, while some other studies had contradictory results. The proliferation of unhealthy foods, such as fast food and Western dietary patterns enriched with a pro-inflammatory diet, increased youth’s E-DII and decreased the healthy eating index among older people. Also, smokers and alcoholics tended to consume a diet with a higher E-DII, which should be investigated in further studies. Black people consumed the most pro-inflammatory diets compared with White people, especially in pregnant women. Education had a negative association with E-DII, while socioeconomic status was positively associated with a pro-inflammatory diet. Therefore, E-DII consumption had no association with access to healthy foods but is more associated with knowledge and cultural dietary habits. Moreover, further nutritional interventions are required to educate the vulnerable populations and also provide better availability of healthy food enriched with anti-inflammatory nutrients in the future. |
