Abstract
RATIONALE Alcopop beverages are generally the first alcoholic beverage that young females drink which contain high levels of sugar and alcohol. The over-consumption of these drinks may encourage alcohol co-administration with methamphetamine (METH) impacting on drinking behaviour and glial function. AIMS The aims of this study were to evaluate the effect of adolescent binge alcohol exposure on consumption level, anxiety-like behaviour, cross-sensitization with METH and on astrocyte expression in reward related brain regions. METHODS Adolescent female Sprague-Dawley rats had daily 1-hour oral alcohol consumption of alcopop (ALCP; with sucrose) or ethanol-only (ETOH; without sucrose), transitioned from 5 to 15% (v/v) ethanol content for 34 days. Water and sucrose groups act as controls. During alcohol withdrawal, rats were tested for anxiety on the elevated plus maze (EPM) and locomotor activity following saline or METH (1 mg/kg i.p) treatment. Brains were then collected to assess astrocyte immunofluorescence for glial fibrillary acidic protein (GFAP) in reward-related brain regions. RESULTS Rats pretreated with 5% ALCP consumed significantly more volume and ethanol intake when compared to 5% EtOH rats. Both ALCP and EtOH groups had a higher preference ratio for 5% than 15% alcohol solutions and ALCP rats had greater ethanol intake at 15% than EtOH rats. Alcohol withdrawal showed no significant differences between groups on anxiety, METH cross-sensitization effects or GFAP intensity in the regions studied. CONCLUSIONS Overall, the addition of sucrose to alcoholic solutions encouraged female rats to consume larger volumes and greater ethanol intake compared to ethanol-only solutions, yet did not have long lasting effects on behaviour and astrocytes.

Linking drug and food addiction via compulsive appetite. Br J Pharmacol 2022; 179:2589-2609. [PMID: 35023154 PMCID: PMC9081129 DOI: 10.1111/bph.15797] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2021] [Revised: 10/09/2021] [Accepted: 10/21/2021] [Indexed: 11/29/2022] Open
Abstract
BACKGROUND AND PURPOSE "Food addiction" is the subject of intense public and research interest. However, this nosology based on neurobehavioral similarities among obese individuals and patients with eating disorders and drug addiction remains controversial. We thus sought to determine which aspects of disordered eating are causally linked to preclinical models of drug addiction. We hypothesized that extensive drug histories, known to cause addiction-like brain changes and drug motivation in rats, would also cause addiction-like food motivation. EXPERIMENTAL APPROACH Rats underwent extensive cocaine, alcohol, caffeine or obesogenic diet histories, and were subsequently tested for punishment-resistant food self-administration or "compulsive appetite", as a measure of addiction-like food motivation. KEY RESULTS Extensive cocaine and alcohol (but not caffeine) histories caused compulsive appetite that persisted long after the last drug exposure. Extensive obesogenic diet histories also caused compulsive appetite, although neither cocaine nor alcohol histories caused excess calorie intake and bodyweight during abstinence. Hence, compulsive appetite and obesity appear to be dissociable, with the former sharing common mechanisms with preclinical drug addiction models. CONCLUSION AND IMPLICATIONS Compulsive appetite, as seen in subsets of obese individuals and patients with binge-eating disorder and bulimia nervosa (eating disorders that do not necessarily result in obesity), appears to epitomize "food addiction". Because different drug and obesogenic diet histories caused compulsive appetite, overlapping dysregulations in the reward circuits, which control drug and food motivation independently of energy homeostasis, may offer common therapeutic targets for treating addictive behaviors across drug addiction, eating disorders and obesity.

Rosen EM, Primeaux SD, Simon L, Welsh DA, Molina PE, Ferguson TF. Associations of Binge Drinking and Heavy Alcohol Use on Sugar and Fat Intake in a Cohort of Southern People Living with HIV. Alcohol Alcohol 2021; 57:226-233. [PMID: 34611697 DOI: 10.1093/alcalc/agab066] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2021] [Revised: 08/24/2021] [Accepted: 08/30/2021] [Indexed: 11/12/2022] Open
Abstract
AIMS To assess whether binge drinking and heavy alcohol use are associated with increased sugar and fat consumption among a Southern cohort of people living with HIV (PWH). METHODS This was a cross-sectional analysis of PWH enrolled in the New Orleans Alcohol use in HIV (NOAH) Study (n = 215). Binge and heavy drinking were identified through a 30-day Alcohol Timeline-Followback and dietary intake was assessed through a 24-hour dietary recall. RESULTS Participants were 65.4% male, 83.3% Black, with a mean age of 49.2 ± 9.9. Heavy drinkers consumed more total calories than abstainers (P = 0.035) and low-to-moderate drinkers (P = 0.024), and binge drinkers consumed more calories than non-binge drinkers (P = 0.025). Binge and heavy drinkers had significantly higher intake of total and saturated fat in grams. However, substantially increased caloric intake among these participants led to non-significant associations for alcohol use with high total and saturated fat intake as a percent of total energy intake (%TEI). Binge drinkers had lower odds of consuming high sugar as a %TEI (odds ratio: 0.31 [0.14, 0.68]). Additionally, sugar intake predicted total and saturated fat intake, and this association was slightly higher among binge drinkers (total fat P-value: 0.12). CONCLUSIONS In this population of PWH, while binge and heavy drinking predicted higher caloric and fat intake in grams, binge drinkers were less likely to consume a high-sugar diet. This analysis suggests that interventions focused on reduced alcohol use may be especially beneficial in reducing metabolic disease burden in PWH if supplemented with information on incorporating lower energy-dense foods with reduced fat.
