Green Tea: Current Knowledge and Issues

Foods, Journal Year: 2025, Volume and Issue: 14(5), P. 745 - 745

Published: Feb. 22, 2025

Green tea possesses antioxidant, anti-inflammatory, anticancer, and antimicrobial activities, reduces body weight, slows down aging. These effects are primarily attributed to catechins contained in green leaves, particularly epigallocatechin-3-gallate. However, humans, the realization of tea's beneficial is limited. In order summarize critically analyze available scientific information about health benefits issues related its use, we conducted an in-depth literature review databases. A number vitro studies reported that modulate various signaling pathways cells, which thought underlie their effects. data on humans scarce, partly due low stability oral bioavailability. Furthermore, may also participate pharmacokinetic interactions when co-administered with certain drugs such as anticancer agents, for cardiovascular diseases, immunosuppressors, etc. As a result, adverse drug reactions or therapy failure occur. conclusion, over years, approaches have been investigated optimize catechin intake achieve but date, use prophylaxis disease treatment remains Therefore, future regarding possibilities administration needed.

The medicinal and aromatic plants as ingredients in functional beverage production

Journal of Functional Foods, Journal Year: 2022, Volume and Issue: 96, P. 105210 - 105210

Published: Aug. 9, 2022

The functional beverages (FBs) are an important segment of food products due to health benefits they provide and their appealing sensory characteristics, suitability affordability. FBs market offers many opportunities for new product development (nutraceuticals, colorants, plant-based medicines products) with desirable effective composition nutrients bioactive molecules (BAMs) aimed deliver improve human well-being. Recently, the use medicinal aromatic plants (MAPs) in production has become increasingly popular specific content (amino fatty acids) BAMs (volatile non-volatile) attributed biological effects benefits. stored leaves, flowers, fruits, seeds, barks roots, mostly include phenolics (phenolic acids, flavonoids, tanins, anthocyanins, lignans stilbenes), essential oils (EOs), terpenoids, alkaloids, phytosterols saponins. features MAPs mainly related volatile compounds EOs, but presence non-volatile compounds, such as phenolics, also contributes properties. Phytochemical profiling plant species containing complex mixtures BAMs, provides numerous categories FBs, opens challenges isolation using conventional advanced extraction techniques, well determination potential effects. This review summarizes most common from selected effects, techniques suitable extracts quality prediction trends, several directions towards future research on strategies.

Molecular Mechanisms of Action of Selected Substances Involved in the Reduction of Benzo[a]pyrene-Induced Oxidative Stress

Molecules, Journal Year: 2022, Volume and Issue: 27(4), P. 1379 - 1379

Published: Feb. 18, 2022

Benzo[a]pyrene (BaP) is a polycyclic aromatic hydrocarbon (PAH) primarily formed by burning of fossil fuels, wood and other organic materials. BaP as group I carcinogen shows mutagenic carcinogenic effects. One the important mechanisms action its free radical activity, effect which induction oxidative stress in cells. induces through production reactive oxygen species (ROS), disturbances activity antioxidant enzymes, reduction level non-enzymatic antioxidants well cytokine production. Chemical compounds, such vitamin E, curcumin, quercetin, catechin, cyanidin, kuromanin, berberine, resveratrol, baicalein, myricetin, catechin hydrate, hesperetin, rhaponticin, taurine, atorvastatin, diallyl sulfide, those contained green white tea, lower induced BaP. They regulate expression genes involved inflammation, therefore can reduce ROS. These substances remove ROS lipid protein peroxidation, formation adducts with DNA, increase enzymatic pro-inflammatory cytokines. undergo chemical modification living cells, results more metabolites formation. Some protective have ability to metabolism, particular cytochrome (CYP P450), reduces metabolites, decreases The aim this review discuss properties BaP, describe activities selected chemicals against based on latest publications.

Major Depressive Disorder (MDD) is a growing disabling condition affecting around 280 million people worldwide. This complex entity the result of interplay between biological, psychological, and sociocultural factors, compelling evidence suggests that MDD can be considered disease occurs as consequence an evolutionary mismatch unhealthy lifestyle habits. In this context, diet one core pillars health, influencing multiple biological processes in brain entire body. It seems there bidirectional relationship malnutrition, depressed individuals often lack certain critical nutrients along with aberrant dietary pattern. Thus, interventions are most promising tools to explore field MDD, specific group (i.e., omega 3, vitamins, polyphenols, caffeine), foods (fish, nuts, seeds fruits, vegetables, coffee/tea, fermented products) or supplements (such S-adenosylmethionine, acetyl carnitine, creatine, amino acids, etc.), which being currently studied. Likewise, nutritional context pattern seem another potential area study, some strategies such Mediterranean have demonstrated relevant benefits patients MDD; although, further efforts still needed. present work, we will state-of-the-art prevention clinical support focusing on properties its main nutrients, foods, patterns their possible implications for these patients.
