Coconut water and coconut milk ameliorate the negative impacts of heat stress on gastrointestinal health by reducing oxidative stress and suppressing inflammatory responses.

2022 Journal of Food Biochemistry Effect of coconut water and milk on heat stress‐induced gastrointestinal tract dysmotility in rats: Role of oxidative stress and inflammatory response Ajeigbe KO, Oladokun OO, Owonikoko MW, Adegoke GA

Experimental Study Coconut Milk Coconut Water Oxidative Stress

The study enlisted four different temperature exposure groups of rats, namely a control group at 30 degrees Celsius, a heat-stressed group exposed to an ambiance of 40 degrees, a heat-stressed group pre-treated with coconut water, and a heat-stressed group with coconut milk. Measurements such as skin and rectal temperatures, as well as evaluations of gastrointestinal motility factors such as intestinal transit, intestinal fluid accumulation, and colonic motility, were taken before and after a two-hour heat exposure over 14 days.

Noticeable increases in gastrointestinal motility factors were observed amongst the heat-stressed rats. However, the introduction of coconut milk and water appeared to reverse these increases. Furthermore, the elevated cortisol levels and intestinal lipid peroxidation in the heat-stressed rats were significantly reduced with the introduction of both coconut products. Likewise, results showed an increase in antioxidant enzyme activities in the rats that received either coconut water or milk, in contrast to the control group. Similarly, the coconut water and milk were seen to suppress inflammatory cytokines while enhancing others. The study also noted significant improvements in intestinal morphology among heat-stressed rats treated with either coconut product.

Fresh and dried ginger displays key botanical, phytochemical and ethnopharmacological differences, which are fundamental for their specific clinical uses in treating gastrointestinal issues.

2022 The American Journal of Chinese Medicine Zingiber officinale: A Systematic Review of Botany, Phytochemistry and Pharmacology of Gut Microbiota-Related Gastrointestinal Benefits Lai W, Yang S, Lin X, Zhang X, Huang Y, Zhou J, et al.

Systematic Review Ginger Gut Microbiota

The methodology used in the research involved a retrospective comparison between Sheng Jiang (SJ, meaning fresh ginger) and Gan Jiang (GJ, meaning dried ginger), two traditional Chinese herbs. The comparison was undertaken specifically considering aspects of botany, phytochemistry, and ethnopharmacology. The research also delved into exploring the traditionally attributed use of ginger, in both its fresh and dried forms, for the treatment of gastrointestinal disorders, and its relationship with human gut microbiota - an aspect that hasn't been considered extensively previously.

The results displayed notable differences between fresh and dried ginger in terms of botany, phytochemical, and ethnopharmacological properties. Fresh and dried ginger are cultivated differently and display distinct physical appearances. This research proposed that these differences lay the foundation for how these two forms of ginger are applied clinically. Furthermore, discussing the pharmacology of gut microbiota-related gastrointestinal benefits, it is suggested that fresh and dried ginger could present innovative and potent avenues for preventing and treating gastrointestinal disorders.

A variety of Chinese herbal medicines have been reported to effectively prevent or treat nonalcoholic fatty liver disease by regulation of the gut microbiota and the gut-liver axis.

2021 Chinese Medicine Herbal therapy for ameliorating nonalcoholic fatty liver disease via rebuilding the intestinal microecology Yang XF, Lu M, You L, Gen H, Yuan L, Tian T, et al.

Systematic Review NAFLD Pu-Erh Tea

The key roles of CHMs in the regulation of gut microbiota and the gut-liver axis along with their mechanisms (such as modulating intestinal permeability, reducing the inflammatory response, protecting liver cells, improving lipid metabolism, and modulating nuclear receptors), were well summarized. All the knowledge and information presented here will be very helpful for researchers to better understand the applications and mechanisms of CHMs for treatment of NAFLD.

Two French natural mineral waters (NMW1 and NMW2) show anti-inflammatory effects and can reduce intestinal inflammation in mice with induced colitis.

2021 International Journal of Molecular Sciences Beneficial Effects of Natural Mineral Waters on Intestinal Inflammation and the Mucosa-Associated Microbiota Barnich N, Rodrigues M, Sauvanet P, Chevarin C, Denis S, Le Goff O, et al.

Experimental Study Colitis Gut Microbiota Intestinal Inflammation

The study investigated the anti-inflammatory effects of two French natural mineral waters (NMWs) - NMW1 (rich in calcium, magnesium, sodium, carbon, and iron) and NMW2 (mainly bicarbonate) - on intestinal inflammation. Intestinal epithelial cells were stimulated with heat-inactivated Escherichia coli or hydrogen peroxide and then treated with NMWs. Additionally, moderate colitis was induced in Balbc/J mice using 1% dextran sulfate sodium. These mice were then given either NMW1, NMW2, or control water. The study assessed general symptoms, histological features of colitis, fecal lipocalin-2 levels, pro-inflammatory KC cytokine levels, and the global mucosa-associated microbiota.

Both NMW1 and NMW2 showed anti-inflammatory effects in treated intestinal cells. In the colitis-induced mice, NMW1 notably reduced inflammation, evidenced by lower disease activity scores, reduced fecal lipocalin-2, decreased release of pro-inflammatory KC cytokines, and smaller intestinal epithelial lesions. NMW1 also helped in maintaining the normal state of mucosa-associated microbiota. These findings suggest the potential of these NMWs in managing inflammatory bowel disease through modulating gut microbiota.

Omega-3 fatty acids found in selected fish oils, particularly smoked eel, effectively managed dyslipidemia and reduced cardiovascular disease risk factors.

2021 Journal of Medicinal Food Influence of Omega-3 Fatty Acid-Rich Fish Oils on Hyperlipidemia: Effect of Eel, Sardine, Trout, and Cod Oils on Hyperlipidemic Mice Kontostathi M, Isou S, Mostratos D, Vasdekis V, Demertzis N, Kourounakis A, et al.

Animal Study Cardiovascular Disease Cholesterol Eel

The study began by inducing dyslipidemia through a high fat diet in a mouse model. After 30 days of this diet, all animals displayed hyperlipidemia. Subsequently, the diet was switched to consist of 90% standard rodent chow and 10% oil derived from different fish varieties (eel, sardine, cod liver, trout). This diet was maintained for the next 60 days. Blood glucose, total blood cholesterol, triglycerides, and high-density lipoprotein were quantified at the end of the study period. Additionally, the fish oils' omega-3 and omega-6 fatty acid percentages and ratio were taken into account by using gas chromatography.

The results showed that incorporating fish oils in the diet considerably improved the hyperlipidemic state triggered by the high-fat diet. Specifically, eel and cod liver oil diets led to significant decreases in triglycerides. Meanwhile, all diets, apart from the standard rodent chow and sardine, resulted in noticeable decreases in blood glucose. Interestingly, smoked eel stood out as the best source for omega-3 fatty acids due to its optimal balance of omega-6 fatty acids, excellently alleviating the mixed hyperlipidemia induced by the high-fat diet.
