Turmeric curcuminoids are associated with better pain relief than NSAIDs in knee osteoarthritis.
The meta-analysis results showed that curcuminoids were significantly more effective than comparators regarding visual analogue scale (VAS) and Western Ontario and McMaster Universities Arthritis Index (WOMAC) pain scores.
However, no significant difference in pain relief or AEs between the high-dose (daily dose ≥1000 mg or total dose ≥42 gm) and low-dose (daily dose <1000 mg or total dose <42 gm) curcuminoid treatments was observed.
When comparing curcumininoids versus NSAIDs, a significant difference in VAS pain was found. For AE analysis, three of our included studies used NSAIDs as comparators, with all reporting higher AE rates in the NSAID group, though significance was reached in only one study.

Review Article Bioactive Compounds Biological Activities Turmeric
The methodology of the research involved analyzing the cultivation, storage, and surrounding environmental factors crucial to turmeric production, such as soil condition and climate. This was intertwined with investigations into the chemical composition of turmeric, focusing mainly on curcumin, its main component. Moving forward, the study then evaluated curcumin analogs and formulations, leading to a deep dive into the relatively new development of nanocurcumin.
The discussion of the research results revealed several interesting findings. Firstly, turmeric exhibited a variety of useful properties, highlighting its role in traditional medicine and livelihood in Indian tribes. Most importantly, the research concluded the impressive potential of nanocurcumin. This altered form of curcumin showed not only enhanced characteristics but also possible applications in the pharmaceutical field, specifically for drug delivery systems.
Moxibustion, a form of traditional Chinese medicine, appears to be an effective and safe treatment for knee osteoarthritis.

Systematic Review Knee Osteoarthritis Moxibustion
The researchers used a series of databases including Embase, PubMed, Web of Science, Cochrane Library, and others to carry out a comprehensive evaluation of previous systematic reviews on the treatment of knee osteoarthritis with moxibustion. They employed the Measurement Tool to Assess Systematic Reviews 2 to assess the methodological quality, Preferred Reporting Item for Systematic Reviews and Meta-analyses for reporting quality, and ROBIS Tool to evaluate the risk of bias in the systematic reviews. They also assessed the strength of evidence with the Grading of Recommendations Assessment, Development and Evaluation tool and carried out a meta-analysis of the total effectiveness rate.
From this process, 10 systematic reviews were selected that had met their criteria. These reviews included the results of 57 randomized controlled trials involving a total of 5,149 participants. However, these reviews were found to have several critical deficiencies, scoring low on the quality scale used. Despite this, moxibustion, and its combination treatment, were shown to improve the total effectiveness rate in knee osteoarthritis. Eight of the reviews had reported adverse events but none were classified as serious in either the moxibustion group or control group.
Pomegranate peel extract supplementation can decrease total cholesterol and triglyceride levels while boosting antioxidant status in obese women with knee osteoarthritis.

Randomised Controlled Trial Knee Osteoarthritis Pomegranate Peel
The research was a randomized, double-blind placebo-controlled trial involving 66 obese women aged 38 to 60 years old with knee osteoarthritis. These participants were split into two groups, the intervention group and control group, each containing 33 members. The intervention group received pomegranate peel extract capsules (500 mg) twice daily for 8 weeks including standard drug therapy while the control group was given a placebo during the same period. All participants' fasting blood samples, anthropometric measurements, dietary intake data, and physical activity levels were collected both before the start and at the end of the trial.
Results analysis showed that pomegranate peel extract supplementation brought down levels of serum total cholesterol, triglyceride and an oxidative stress marker while enhancing levels of some antioxidant enzymes and the overall antioxidant capacity when compared to the control group. However, there were no noticeable alterations between the two groups in terms of low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and body mass index by the end of the experiment.
Consumption of certain foods like rapeseed/canola oil, avocados, and turmeric can lead to moderate to large reductions in LDL cholesterol levels.

The research was carried out by conducting a systematic evaluation of existing guidelines, systematic reviews, and Randomised Control Trials (RCTs); we have only referred to the latter for studies on coffee intake. This was done on databases such as PubMed, Cochrane Database of Systematic Reviews, and Cochrane Central Register of Controlled Trials, alongside a search on the Trip database for guidelines. The time frame for the study was from its inception up until June 2019 and October 2019 respectively. Studies were included if they were at least 13 days in duration and were in English. Using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) method, 37 guidelines, 108 systematic reviews, and 20 RCTs were evaluated to analyze the strength of evidence in the context of food impacts on LDL cholesterol levels.
The results of the research reveal that foods high in unsaturated and low in saturated and trans fatty acids such as rapeseed or canola oil, those with added plant sterols/stanols, and those high in soluble fibre like oats, barley and psyllium cause moderate reductions in LDL cholesterol. A moderate to a large increase was observed with unfiltered coffee though. Soy protein, tomatoes, flaxseeds, and almonds cause small reductions. Meanwhile, foods like avocados and turmeric cause moderate to large reductions with a moderate level of evidence supporting this observation. Other foods like pulses, hazelnuts, walnuts, high-fiber/wholegrain foods, green tea result in small to moderate reductions, and sugar causes a small increase. Several foods identified were either neutral or had low or very low evidence regarding their effects on LDL cholesterol levels.
Green tea, coffee, wine, and curry have beneficial health effects due to the polyphenols they contain, which possess both antioxidant and pro-oxidant properties.

Review Article Anticancer Antioxidant Curry
The research leverages epidemiological studies, clinical trials, cell-based studies and animal tests to examine the effects of green tea, coffee, wine, and curry -- and their key polyphenols -- on human health. The polyphenols investigated include epigallocatechin gallate in green tea, chlorogenic acid in coffee, resveratrol in wine, and curcumin in curry. The study concentrates on the workings of these polyphenols, primarily focusing on reactive oxygen species (ROS), and how they perform both anti- and pro-oxidant functions, fundamentally influencing different enzymes and factors with health contributions.
In the discussion of the results, it is mentioned that the anti-oxidative actions of these polyphenols assist in the scavenging of ROS and the downregulation of the nuclear factor-κB, yielding beneficial anti-inflammatory effects. Conversely, their pro-oxidant actions appear to elevate ROS production, encouraging the activation of 5'-AMP-activated protein kinase that regulates different enzymes and factors for health improvement. However, the exact mechanism of how these polyphenols exhibit either pro- or anti-oxidant effects remains unclear. Also, the research underscores that while many studies note their health benefits, some others show no positive effects on health conditions such as obesity, suggesting that outcomes could be influenced by various study factors.
