Changes in food behavior during the first lockdown of COVID-19 pandemic: A multi-country study about changes in eating habits, motivations, and food-related behaviors

Lifestyle pattern changes, eating disorders, and sleep quality in diabetes: how are the effects of 18 months of COVID-19 pandemic being felt?

“…Some of the factors that may explain this worsening may be attributed to the COVID-19 pandemic, according to previous studies. A multicentric survey found that common consequences of lockdown measures are related to decreased access to food variety and difficulty to buy food due to price raises [25]. Another study performed by Lucile Marty et al [4] indicated that changes in daily routine contribute to lower dietary nutritional quality, expressed by the increased daily energy intake and unhealthy foods (processed meat, sugar-sweetened beverages, and alcohol), when comparing lockdown with the pre-pandemic period.…”

Commentary: Changes in eating and changes in affect during early Covid confinement

“…Grunert et al used an on-line survey in Denmark before and during the first lockdown. People were divided into those who like cooking, those who do not, or no opinion, and these distinctions were reflected in differences in food choices.. Lamy et al (2022) also used an on-line questionnaire in 16 countries to study healthy and unhealthy eating. Agnoli and Charters studied beverage consumption globally during Covid and found increased consumption of beer among non-professionals, and increased consumption of wine among wine professionals; alcohol consumption either increased or did not change for large proportions of the two groups.…”

“…Adherence to the Med Diet was higher in Southern Europe, especially among people 51+ with a previous high adherence to the diet. Lamy et al (2022) describe the division of their sample into healthy (approximately 2/3) and unhealthy eaters (approximately 1/3), with the healthy eaters more focused on health and weight control, and less focused on pleasure or affect regulation. Piochi et al (2021) report an increase in snacking by 33% of their sample, and an increase in meal duration by 44% of their sample, both of which could contribute to increased consumption.…”

“… Lamy et al (2022) also studied compared pre-Covid and during Covid behavior during the first lockdown (April-June 2020) across 16 countries (72.8% Europe, 12.8% Africa, 2.2% North America, and 12.2% South America). Measures were taken of eating motivations, dietary habits and eating related behaviors.…”

Systematic Literature Review on Parental Perspectives of the Impact of COVID-19 Lockdown on Food-Related Behaviors

“…Most of the nutrition and dietary recommendations to combat viral infections, including COVID-19, revolve around maintaining a balanced diet (Naja and Hamadeh 2020), as existing evidence highlights that nutrients play an essential role in immune cell triggering, interaction, differentiation, or functional expression (Gleeson, Nieman, and Pedersen 2004;Wypych, Marsland, and Ubags 2017;Valdés-Ramos et al 2010), thus having a profound effect on people's immune system and disease susceptibility. Research conducted during the COVID-19 outbreak alerted people to the importance of nutrition in protecting people's health in times of pandemic (Lamy et al 2022), reporting the link between the levels of various nutrients and the severity of symptoms in COVID-19 (Martineau and Forouhi 2020;Jain et al 2020;Carr and Rowe 2020), or relating diet-related ill-health (e.g., obesity) to a worse prognosis for the disease (Tamara and Tahapary 2020). Additional efforts are needed to maintain this level of public focus on diet-related health and immunity after the lockdown; in addition, educating about preserving the shelf life of fresh produce could prepare the public for better managing the food in future outbreaks.…”
