“…In the US, a pooled analysis of three longitudinal cohort studies (Nurses’ Health Study, Nurses’ Health Study II and Health Professionals Follow-up Study) found that consuming ≥4 servings/week of broccoli, carrots, and tofu/soybeans was associated with a lower risk of hypertension compared to consuming <1 serving/month [43]. However, the Tehran Lipid and Glucose Study, which involved 1546 normotensive adults, did not find an association between incident hypertension and dietary phytochemical intake, which provided an indirect estimate of soybean consumption [44]. …”

Beyond the Cholesterol-Lowering Effect of Soy Protein: A Review of the Effects of Dietary Soy and Its Constituents on Risk Factors for Cardiovascular Disease

The hypocholesterolemic effect of soy is well-documented and this has led to the regulatory approval of a health claim relating soy protein to a reduced risk of cardiovascular disease (CVD). However, soybeans contain additional components, such as isoflavones, lecithins, saponins and fiber that may improve cardiovascular health through independent mechanisms. This review summarizes the evidence on the cardiovascular benefits of non-protein soy components in relation to known CVD risk factors such as hypertension, hyperglycemia, inflammation, and obesity beyond cholesterol lowering. Overall, the available evidence suggests non-protein soy constituents improve markers of cardiovascular health; however, additional carefully designed studies are required to independently elucidate these effects. Further, work is also needed to clarify the role of isoflavone-metabolizing phenotype and gut microbiota composition on biological effect.

“…This index is an easy and practical method for the assessment of phytochemical intake and diet quality in clinical practice. Several epidemiologic studies have investigated the association between DPI and CVD risk factors including oxidative stress, obesity, blood pressure, blood sugar, lipid profile and cancer (25)(26)(27)(28)(29)(30)(31)(32)(33) . These studies showed the DPI was inversely related to obesity, oxidative stress, hypertriacylglycerolaemia, hypercholesterolaemia, insulin resistance, prediabetes, hypertension and breast cancer.…”

Association of dietary phytochemical index and mental health in women: a cross-sectional study

et al. 2019

Previous studies have shown that unhealthy dietary patterns are among the most important modifiable risk factors in the development of mental health disorders. We examined the association of dietary phytochemical index (DPI) with symptoms of depression, anxiety and psychological distress in Iranian women. In this cross-sectional study, a total of 488 women aged 20–50 years old attending health centres in the south of Tehran in 2018 were included. A validated and reliable FFQ was used for dietary assessment. Symptoms of depression, anxiety and psychological distress were assessed using a validated depression, anxiety, stress scales questionnaires with twenty-one-items. DPI was estimated using the following formula: (daily energy derived from phytochemical-rich foods (kJ)/total daily energy intake (kJ))×100. The mean age of the study participants was 31·9 (sd 7·7) years. The prevalence of depressive symptoms, anxiety and psychological distress among study participants was 34·6, 40·6 and 42·4 %, respectively. After controlling for potential confounders, women in the highest tertile of DPI had a lower prevalence of depressive symptoms (OR 0·22; 95 % CI 0·12, 0·38) and anxiety (OR 0·33; 95 % CI 0·20, 0·55), as well as psychological distress (OR 0·30; 95 % CI 0·18, 0·49) compared with those in the lowest tertile. In conclusion, we found a significant association between DPI and mental health in women. Prospective studies are needed to confirm these findings.

“…PI has been shown to be inversely associated with body mass index, waist circumference, waist-to-hip ratio, and plasma oxidative stress [31]. A higher dietary PI was shown to have favorable effects on prevention of weight gain and reduction of body adiposity in adults [32], along with improved lipids [33,34], and lowered risk of hypertension [35] and breast cancer [36].…”

Over the past decades, thousands of published studies have amassed supporting recommendations to consume fruits and vegetables for physiological and psychological health. Newer research has emerged to suggest that these plant-based foods contain a plethora of not only vitamins and minerals, but perhaps, most importantly, phytonutrients. These phytonutrients have known pleiotropic effects on cellular structure and function, ultimately resulting in the modulation of protein kinases and subsequent epigenetic modification in a manner that leads to improved outcomes. Even though eating fruits and vegetables is a well-known feature of a healthy dietary pattern, population intakes continue to be below federal recommendations. To encourage consumers to include fruits and vegetables into their diet, an “eat by color” approach is proposed in this review. Although each individual food may have numerous effects based on its constituents, the goal of this simplified approach was to identify general patterns of benefits based on the preponderance of scientific data and known mechanisms of food-based constituents. It is suggested that such a consumer-oriented categorization of these plant-based foods may lead to greater recognition of their importance in the daily diet throughout the lifespan. Other adjunctive strategies to heighten awareness of fruits and vegetables are discussed.

Abstract: Consumption of phytochemical-rich foods may prevent the development of HTN. Further investigations are, however, recommended.
