The present systematic review and meta-analysis were accomplished to understand the effects of tart cherry juice consumption on body composition and anthropometric measures. Five databases were searched using relevant keywords from inception to January 2022. All clinical trials investigating the effect of tart cherry juice consumption on body weight (BW), body mass index (BMI), waist circumference (WC), fat mass (FM), fat-free mass (FFM), and percentage body fat (PBF) were included. Out of 441 citations, 6 trials that enrolled 126 subjects were included. Tart cherry juice consumption significantly did not reduce BW (weighted mean difference [WMD], −0.4 kg; 95% confidence interval [CI], −3.25 to 2.46; p = 0.789; GRADE = low), BMI (WMD, −0.07 kg/m2; 95% CI, −0.89 to 0.74; p = 0.857; GRADE = low), FM (WMD, 0.21 kg; 95% CI, −1.83 to 2.25; p = 0.837; GRADE = low), FFM (WMD, −0.12 kg; 95% CI, −2.47 to 2.27; p = 0.919; GRADE = low), WC (WMD, 1.69 cm; 95% CI, −1.88 to 5.27; p = 0.353; GRADE = low), and PBF (WMD, 0.18%; 95% CI, −1.81 to −2.17; p = 0.858; GRADE = low). Overall, these data suggest that tart cherry juice consumption has no significant effect on BW, BMI, FM, FFM, WC, and PBF.

The present systematic review and meta-analysis were conducted in order to investigate the effects of capsinoids and fermented red pepper paste (FRPP) supplementation on lipid profile. Relevant studies were identified by searches of five databases from inception to November 2021 using relevant keywords. All clinical trials investigating the effect of capsinoids and FRPP on total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) were included. Out of 1,203 citations, eight trials that enrolled 393 participants were included. Capsinoids and FRPP resulted in a significant reduction in TC (weighted mean differences [WMD], −9.92 mg/dL; 95% confidence interval [CI], −17.92 to −1.92; p = 0.015) but no significant changes in TG (WMD, −19.38 mg/dL; 95% CI, −39.94 to 1.18; p = 0.065), HDL-C (WMD, 0.83 mg/dL; 95% CI, −0.76 to 2.42; p = 0.305) and LDL-C (WMD, −0.59 mg/dL; 95% CI, −4.96 to 3.79; p = 0.793). Greater effects on TC were detected in trials performed on duration lasting less than twelve weeks, mean age of > 40, both sexes, and sample size of > 50. TG was reduced by using FRPP in studies conducted on mean age of > 40. HDL-C increased by using FRPP in studies conducted on duration of < 12 weeks, mean age of > 40, and sample size of ≤ 50. Overall, these data provided evidence that capsinoids and FRPP supplementation has beneficial effects on TC but not TG, HDL-C, and LDL-C.

Our purpose was to assess the association between plant-based dietary patterns and breast cancer (BrCa) among Iranian women. This hospital-based case-control study included 150 newly diagnosed BrCa cases and 150 age-matched controls from the Cancer Research Center, Imam Khomeini hospital, Iran. Three indices of a plant-based diet were first calculated: plant-based diet index (PDI), the healthy PDI (hPDI), and the unhealthy PDI (uPDI). In the overall PDI, all plant foods scored positively. In hPDI and uPDI, healthy and less healthy plant foods scored positive, respectively. The adjusted odds ratio (OR) in the highest adherence of PDI was 1.00 (95% confidence interval [CI], 0.55–1.83). In hPDI, 0.89 (95% CI, 0.49–1.62); in uPDI, 1.80 (95% CI, 0.95–3.42). The adjusted OR after subgroup analysis for body mass index (BMI) was as follow, BMI > 25: 0.77(95% CI, 0.37–1.61) comparing highest with the lowest tertile of PDI, 0.91(95% CI, 0.44–1.89) comparing highest with the lowest tertile of hPDI and this value for uPDI was 2.04 (95% CI, 0.91–4.56). BMI < 25: OR for top tertile of PDI was 1.82 (95% CI, 0.48–6.93), top tertile of hPDI was 1.47 (95% CI, 0.35–6.22) and top tertile of uPDI was 2.29 (95% CI, 0.54–9.70). Our results revealed no significant association between none of the PDIs and the chance of BrCa in Iranian women. Continued and expanded research, evaluated by different methods and BrCa is urgently needed to build the foundation for future progress in evidence-based public health efforts.

In the present research, we have evaluated the association between patterns of nutrient intake and obesity. The present cross-sectional study recruited 850 adults aged between 20–59 years old. Dietary intakes were assessed with three 24-hour recalls. As well, data on anthropometric measures were collected. General obesity was specified as body mass index ≥ 30 kg/m2. Factor analysis was conducted, and followed by a varimax rotation, was performed to extract major nutrient patterns. Our analysis identified three major nutrient patterns: The first nutrient pattern was characterized by the high consumption of saturated fatty acids (SFAs), protein, vitamins B1, B2, B6, B5, B3, B12, Zinc, and iron. The second nutrient pattern was rich in total fat, polyunsaturated fatty acids, monounsaturated fatty acids, SFAs, oleic acid, linolenic acid, zinc, vitamin E, α-tocopherol, and β-carotene. The third one was greatly loaded with protein, carbohydrate, potassium, magnesium, phosphorus, calcium, vitamin C, and folate. Women in the third quintile of the first pattern were less likely to be generally obese in the fully adjusted model (odds ratio, 0.44; 95% confidence interval, 0.25–0.75). None of the other nutrient patterns had a significant association with obesity, even after adjusting for confounders. Adherence to a nutrient pattern rich in water-soluble vitamins was significantly associated with a greater chance of general obesity among women. Further studies in other populations, along with future prospective studies, are required to confirm these findings.
