Lodge M, Dykes R, Kennedy A. Regulation of Fructose Metabolism in Nonalcoholic Fatty Liver Disease. Biomolecules 2024; 14:845. [PMID: 39062559 PMCID: PMC11274671 DOI: 10.3390/biom14070845] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2024] [Revised: 07/02/2024] [Accepted: 07/08/2024] [Indexed: 07/28/2024] Open
Abstract
Elevations in fructose consumption have been reported to contribute significantly to an increased incidence of obesity and metabolic diseases in industrial countries. Mechanistically, a high fructose intake leads to the dysregulation of glucose, triglyceride, and cholesterol metabolism in the liver, and causes elevations in inflammation and drives the progression of nonalcoholic fatty liver disease (NAFLD). A high fructose consumption is considered to be toxic to the body, and there are ongoing measures to develop pharmaceutical therapies targeting fructose metabolism. Although a large amount of work has summarized the effects fructose exposure within the intestine, liver, and kidney, there remains a gap in our knowledge regarding how fructose both indirectly and directly influences immune cell recruitment, activation, and function in metabolic tissues, which are essential to tissue and systemic inflammation. The most recent literature demonstrates that direct fructose exposure regulates oxidative metabolism in macrophages, leading to inflammation. The present review highlights (1) the mechanisms by which fructose metabolism impacts crosstalk between tissues, nonparenchymal cells, microbes, and immune cells; (2) the direct impact of fructose on immune cell metabolism and function; and (3) therapeutic targets of fructose metabolism to treat NAFLD. In addition, the review highlights how fructose disrupts liver tissue homeostasis and identifies new therapeutic targets for treating NAFLD and obesity.

Sugar-sweetened beverage but not diluted cloudy apple juice consumption induces post-prandial endotoxemia in healthy adults. NPJ Sci Food 2024; 8:38. [PMID: 38906893 PMCID: PMC11192722 DOI: 10.1038/s41538-024-00283-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2024] [Accepted: 06/14/2024] [Indexed: 06/23/2024] Open
Abstract
Sugar beverages are discussed as critical in the development of metabolic endotoxemia. Here, employing a cross-over design study we assessed the effect of diluted cloudy apple juice (AJ), an iso-caloric and -sweetened placebo (P), or water (W) on post-prandial endotoxemia in healthy, normal weight adults. After obtaining fasting blood, 19 healthy men and women consumed 500 mL AJ, P, or W in a randomized order and blood was taken 120 and 180 min later. Caco-2 cells were incubated with the beverages. Markers of intestinal barrier function were assessed. The intake of P but not of AJ or W was associated with a significant increase in TLR2 ligands and bacterial endotoxin in serum after 120 min and 180 min, respectively. P but not AJ significantly increased bacterial toxin permeation in Caco-2 cells. Our results suggest that the effects of sugar-sweetened beverages on markers of intestinal barrier function markedly differ from those of fruit juices.

The impact of poor fetal growth and chronic hyperpalatable diet exposure in adulthood on hippocampal function and feeding patterns in male rats. Dev Psychobiol 2024; 66:e22459. [PMID: 38372503 DOI: 10.1002/dev.22459] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Revised: 12/05/2023] [Accepted: 01/02/2024] [Indexed: 02/20/2024]
Abstract
Poor fetal growth affects eating behavior and the mesocorticolimbic system; however, its influence on the hippocampus has been less explored. Brain insulin sensitivity has been linked to developmental plasticity in response to fetal adversity and to cognitive performance following high-fat diet intake. We investigated whether poor fetal growth and exposure to chronic hyperpalatable food in adulthood could influence the recognition of environmental and food cues, eating behavior patterns, and hippocampal insulin signaling. At 60 days of life, we assigned male offspring from a prenatal animal model of 50% food restriction (FR) to receive either a high-fat and -sugar (HFS) diet or standard chow (CON) diet. Behavioral tests were conducted at 140 days, then tissues were collected. HFS groups showed a diminished hippocampal pAkt/Akt ratio. FR-CON and FR-HFS groups had higher levels of suppressor of cytokine signaling 3, compared to control groups. FR groups showed increased exploration of a novel hyperpalatable food, independent of their diet, and HFS groups exhibited overall lower entropy (less random, more predictable eating behavior) when the environment changed. Poor fetal growth and chronic HFS diet in adulthood altered hippocampal insulin signaling and eating patterns, diminishing the flexibility associated with eating behavior in response to extrinsic changes in food availability in the environment.

Eur J Endocrinol 2024; 190:104-112. [PMID: 38291515 DOI: 10.1093/ejendo/lvae006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/27/2023] [Revised: 01/03/2024] [Accepted: 01/08/2024] [Indexed: 02/01/2024]
Abstract
OBJECTIVE To assess the association between fructose consumption and serum sex hormone-binding globulin (SHBG), (free) testosterone, and risk of hyperandrogenism in a population-based cohort. DESIGN An observational and genetic association study in participants of the UK Biobank (n = 136 384 and n = 383 392, respectively). METHODS We assessed the relationship of (1) the intake of different sources of fructose (ie, total, fruit, fruit juice, and sugar-sweetened beverages [SSBs]) and (2) rs2304681 (a missense variant in the gene encoding ketohexokinase, used as an instrument of impaired fructose metabolism), with SHBG, total and free testosterone levels, and risk of hyperandrogenism (free androgen index >4.5). RESULTS The intake of total fructose and fructose from fruit was associated with higher serum SHBG and lower free testosterone in men and women and lower risk of hyperandrogenism in women. In contrast, fructose intake from SSB (≥10 g/day) was associated with lower SHBG in men and women and with higher free testosterone levels and risk of hyperandrogenism in women (odds ratio [OR]: 1.018; 95% confidence interval [CI]: 1.010; 1.026). Carriers of the rs2304681 A allele were characterized by higher circulating SHBG (both men and women), lower serum free testosterone (women), and a lower risk of biochemical hyperandrogenism (OR: 0.997, 95% CI: 0.955; 0.999; women) and acne vulgaris (OR: 0.975, 95% CI: 0.952; 0.999; men and women combined). CONCLUSIONS The consumption of ≥10 g/day fructose from SSB, corresponding to ≥200 mL serving, is associated with a 2% higher risk of hyperandrogenism in women. These observational data are supported by our genetic data.

Am J Clin Nutr 2023; 118:1000-1009. [PMID: 37659725 PMCID: PMC10636232 DOI: 10.1016/j.ajcnut.2023.08.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2023] [Revised: 08/26/2023] [Accepted: 08/30/2023] [Indexed: 09/04/2023] Open
Abstract
BACKGROUND Higher intake of total sugar has been linked with coronary heart disease (CHD) risk, but the role of individual sugars, particularly fructose, is uncertain. OBJECTIVES This study aimed to investigate the associations of individual dietary sugars with CHD risk. METHODS In prospective cohort studies, we followed 76,815 women (Nurses' Health Study, 1980-2020) and 38,878 men (Health Professionals Follow-up Study, 1986-2016). Sugar and carbohydrate intake, including total fructose equivalents ([TFE] from fructose monosaccharides and sucrose), total glucose equivalents ([TGE] from glucose monosaccharides, disaccharides, and starch), and other sugar types, was measured every 2 to 4 y by semiquantitative food frequency questionnaires. RESULTS We documented 9,723 incident CHD cases over 40 years. In isocaloric substitution models with total fat as a comparison nutrient, comparing extreme quintiles of intake, hazard ratios (HRs), 95% confidence interval [CI]) for CHD risk were 1.31 (1.20 to 1.42; Ptrend < 0.001) for TGE and 1.03 (0.94 to 1.11; Ptrend = 0.25) for TFE. TFE from fruits and vegetables was not associated with CHD risk (Ptrend = 0.70), but TFE from added sugar and juice was associated with CHD risk (HR: 1.12, 95% CI: 1.04 to 1.20; Ptrend < 0.01). Intakes of total sugars and added sugar were positively associated with CHD risk (HRs: 1.16, 95% CI: 1.07 to 1.26, Ptrend < 0.001; 1.08, 95% CI: 0.99 to 1.16, Ptrend = 0.04). CONCLUSIONS Intakes of TGE, total sugar, added sugar, and fructose from added sugar and juice were associated with higher CHD risk, but TFE and fructose from fruits and vegetables were not.
