“…Among vegetable sources, green leafy vegetables provided greater benefits, whereas kernel fruits provided greater benefits among fruit sources. An inverse association between diet diversity and CVD incidence was also observed among non-Europeans consuming diverse food groups ( 36 ) . In addition, the consumption of low-fat dairy products, less red meat and less cooking oil in the CHH diet-SC limited the intake of SFA.…”

Sichuan cuisine was previously fitted into the Chinese Heart-Healthy Diet (CHH) trial to verify the antihypertensive effect. Whether the modified Sichuan diet lessens cardiovascular disease (CVD) is not fully explored. We aimed to estimate the effects of the Sichuan version of CHH diet (CHH diet-SC) on the 10-year risk of CVD and vascular age. A single-blinded randomised controlled feeding trial was conducted. General CVD prediction model was used in manners of intention-to-treat and per-protocol set. After a 7-d run-in period, fifty-three participants with pre- and grade I hypertension from local communities were randomised and provided with either CHH diet-SC (n 27) or a control diet (n 26) for 4 weeks. Mean absolute and relative estimated CVD risks were reduced by 4·5 % and 27·9 % in the CHH diet-SC group, and the between-group relative risk reduction was 19·5 % (P < 0·001) using linear mixed-effects models. The sensitivity analysis with datasets and models showed consistent results, and pre-specified factors were not associated with the intervention effects. The vascular age of CHH-SC group was theoretically 4·4 years younger than that of the control group after intervention. Compared with a typical diet, adopting the CHH diet-SC over 1 month significantly reduced 10-year CVD risks and vascular ages among local adults with mild hypertension.

“…This approach aligns with the principles of the Mediterranean diet, which has been associated with beneficial health outcomes beyond its anti-inflammatory effects. The integration of a wide range of foods ensures that the diet provides all necessary macro and micronutrients, supporting overall health and potentially reducing the risk of chronic pain 71 , 72 . It's important to consider that diet is one component of a holistic health strategy, and its optimal composition may vary among individuals.…”

Chronic pain, a substantial public health issue, may be influenced by dietary patterns through systemic inflammation. This cross-sectional study explored the association between Dietary Inflammatory Index (DII) and chronic pain among 2581 American adults from NHANES data. The DII, ranging from − 4.98 to 4.69, reflects the inflammatory potential of the diet, with higher scores indicating greater pro-inflammatory capacity. Our findings showed no significant association between the continuous DII score and chronic pain prevalence. However, a nonlinear relationship emerged. When the DII was categorized, a significant association between higher DII scores (DII ≥ 2.5) and chronic pain prevalence was observed. The analysis uncovered a U-shaped pattern, with an inflection point at a DII score of − 0.9, indicating an association between both low and high levels of dietary inflammation are associated with higher pain prevalence. This nuanced interaction between dietary inflammation and chronic pain indicates the possibility of incorporating dietary modification into pain management strategies and underscores the need for further research into the long-term effects of diet on chronic pain.

“…Diversified food enables women to get all the required nutrients and it is known to improve maternal and newborn outcomes including improving health during pregnancy and lowering the risk of anaemia during pregnancy and the risk of having a baby with low birth weight [ 1 , 33 , 34 ]. Also, it has been found to reduce the risk of death in a systematic review by Mozaffari (2022), which found a 22% reduced risk of death in adults consuming diets with four or more food groups [ 35 ]. In Tanzania, however, the higher Dietary Diversity Score (DDS) was associated with a lower risk of small for gestational age (SGA) [ 36 ].…”

Background Antenatal care (ANC) is crucial for reducing maternal morbidity and mortality, especially in low-resource settings. During antenatal care, women are provided with resources for enhancing their dietary diversity, like nutrition education and counseling. Improved nutrition knowledge influences positive nutritional behavior change, like women’s improved dietary diversity, which may increase the likelihood of a healthier pregnancy and delivery experience. Objective This study aim was to assess dietary diversity and associated factors among pregnant women attending antenatal care in the Coast region of Tanzania. Methods The descriptive cross-sectional study design was used to assess dietary diversity and associated factors among 338 pregnant women. A semi-structured questionnaire collected information from pregnant women on social demographic characteristics, nutrition knowledge and dietary diversity. Women were classified as having a varied diet if they had consumed at least five of the ten food groups over the previous twenty-four hours. Multivariable logistic regression analyses were used to identify predictors of dietary diversity in pregnant women. Results Only 28% (95% CI: 23.5–33.1) (n = 95) of pregnant women met the minimum dietary diversity, and 18% (95% CI: 13.8–21.9) (n = 59) were considered to have a high level of nutrition knowledge. Living near a health facility (AOR = 1.77, CI 1.02, 3.06), having high nutrition knowledge (AOR = 2.58, 95% CI: 1.36, 4.89), and being pregnant for the first time (AOR = 2.44, 95% CI: 1.09, 5.44) were associated with adequate dietary diversity. Conclusion Pregnant women in the study were found to have low knowledge about nutrition and inadequate dietary diversity intake. The findings underscore the need to improve nutrition knowledge provision in antenatal clinics by emphasizing the importance of a diversified and high-quality diet. Healthcare providers in antenatal care clinics should consistently provide nutrition education and counseling to pregnant women and promote their diversified food consumption. Such knowledge may eventually promote healthier pregnancy and child development by curbing the nutritional deficiencies experienced during pregnancy.
