Anti-inflammatory catechins -
Additionally, catechins can be used to reduce the amount of fat and sugar in food products, making them healthier options. Catechins are a type of antioxidant found in green tea and other plants. They have been linked to a variety of health benefits, including improved heart health, reduced inflammation, and improved cognitive function.
They may also help protect against certain types of cancer, reduce the risk of type 2 diabetes, and help with weight loss. Additionally, catechins may help reduce the risk of stroke and other cardiovascular diseases.
While they have been linked to a number of potential health benefits, there are also some potential risks associated with taking catechins as a dietary supplement.
These risks include an increased risk of bleeding, liver damage, and allergic reactions. Additionally, catechins may interact with certain medications, such as blood thinners, and can cause side effects such as nausea, vomiting, and headaches.
It is important to speak with a healthcare professional before taking any dietary supplement, including catechins, to ensure that it is safe for you. Catechins are regulated differently across the world.
In the United States, catechins are regulated as dietary supplements by the Food and Drug Administration FDA. In the European Union, catechins are regulated as food additives by the European Food Safety Authority EFSA.
In Australia, catechins are regulated as food ingredients by the Australian Food Standards Code. In Canada, catechins are regulated as natural health products by Health Canada. Tags: Antioxidants.

It has been reported that AMPK and SIRT1 have synergistic function in transcriptional factors and signal transduction proteins of inflammation response [ 31 ]. The activation of SIRT1 and AMPK significantly reduces the production of inflammatory factors and further inhibites the inflammatory response [ 32 ].
The activation of AMPK, SIRT1, FOXO3a and NF-κB signaling by TNF-α has been reported to cause inflammation and insulin resistance in several cell lines [ 33 ].
This study was to research that two energy target AMPK and SIRT1 serve as negative regulators of TNF-α induced inflammatory in 3T3-L1 adipocytes. In this experiment, TNF-α promoted the expression of AMPK, SIRT1, FOXO3a and NF-κB, but inhibited the expression of the phosphorylated AMPK p-AMPK , phosphorylated SIRT1 p-SIRT1 , phosphorylated FOXO3a p-FOXO3a and phosphorylated NF-κB p-NF-κB.
In contrast, supplementation of catechin markedly increased the level of p-AMPK, p-SIRT1, p-FOXO3a and p-NF-κB, and gradually closed to the control group. Similar effects were observed for the extracts from grape [ 6 ], black tea [ 22 ], brown alga [ 34 ].
Consistent with our findings, a few studies have also demonstrated that synergistic activation of AMPK and SIRT1 can promote the expression of anti-inflammatory cytokines, and prevent the expression of pro-inflammatory cytokines via NF-κB signaling pathway in LPS-induced cells [ 35 , 36 ].
SIRT1, as a downstream signal, mediates the anti-inflammatory effect of AMPK, which provides a mechanism of AMPK and SIRT1 in the inflammatory response [ 4 ].
The anti-inflammatory effect of AMPK is dependent on SIRT1, and changes in AMPK activity often affect the content and activity of SIRT1 [ 20 ].
Our results indicated that AMPK and SIRT1 also have effect on insulin sensitivity through their ability to antagonize TNF-α induced inflammation. Catechine supplementation remarkably reduced the phosphorylation level of AMPK, SIRT1, FOXO3a and NF-κB irrespective to the presence or absence of insulin.
It seems that AMPK and SIRT1 synergistically regulate metabolic or inflammatory pathways. AMPK and SIRT1 may activate and feedback each other based on different cellular or physiological requirements. Activation of AMPK increases the expression of SIRT1 in 3T3-L1 adipocytes. Accordingly, activation of the AMPK-SIRT1-FoxO3a pathway by catechine may exert beneficial effects on inflammation treatment.
Our study demonstrates the anti-inflammation effect of catechine in mature adipocytes through activation of the AMPK pathway, which consequently modulates gene expression of NF-κB through up-regulation of SIRT1 and FOXO3a.
Therefore, taking 3T3-L1 adipocytes as the model to study the mechanism of chronic inflammatory caused by metabolic disorders such as obesity and diabetes, which can be targeted for the prevention and treatment of metabolic inflammation, and also has important theoretical significance for revealing the anti-inflammatory mechanism of catechin.

| Activity of catechins and their applications | Biomedical Dermatology | Full Text | The aim of this study is to investigate the effect of some phenolic compounds such as catechines that heavily present in tea and cocoa extracts against diabetic induction using streptozotocin STZ treated rats. Blood glucose, glycosylated hemoglobin, serum insulin and lipid profile were assessed in all groups. In addition, HOMA-IR and atherogenic index were calculated. Further, inflammatory markers and other metabolic parameters such as endothelial dysfunction and oxidative stress markers were estimated. The data showed that all the used extracts had antioxidant and anti-inflammatory effect against STZ induced diabetes. Although, green tea extract showed the maximum improvement in antioxidants levels and cocoa extract showed the maximum improvement in inflammatory markers. We concluded that tea and cocoa extracts had a protective effect against STZ induced diabetes which attributed to their free radical scavenging antioxidants that reduced both the production and release of inflammatory markers.

Keen, PhD, Sheri Zidenberg-Cherr, PhD, Center for Nutrition in Schools, Department of Nutrition, University of California, Davis, Catechins and epicatechins are phytochemical compounds found in high concentrations in a variety of plant-based foods and beverages. Based on their structure, these compounds are classified as flavanols and include the following compounds: catechin, epicatechin, epigallocatechin, epicatechin gallate, and epigallocatechin gallate. High concentrations of catechin can be found in red wine, broad beans, black grapes, apricots and strawberries. Finally, epigallocatechin, epicatechin gallate, and epigallocatechin gallate are found in high concentrations in both black and green tea 1. The consumption of foods rich in catechins and epicatechins has been associated with a variety of beneficial biological effects including increased plasma antioxidant activity ability of plasma to scavenge free radicals , brachial artery dilation blood vessel expansion , fat oxidation, and resistance of LDL to oxidation and promotion of gut health 1. The gut microbiota can biotransform catechin and epicatechin, and conversely the presence of these nutrients in the gut can induce changes in gut microbial populations. Numerous studies have investigated the relationship between consumption of red wine and susceptibility to certain chronic diseases including lung cancer, prostate cancer, and cardiovascular disease. Antioxidant capacity is the ability for a compound or compounds to reduce the concentration of free radicals in a given system. Tea has been consumed by Asian populations for thousands of years and is purported to have numerous beneficial effects on health.
