More than one hundred years ago the “protein hypothesis” of the pathogenesis of atherosclerosis and its association with cardiovascular disease was put forward on the basis of animal experiments; however, it has so far never been verified in humans. This theory was soon replaced by the “lipid hypothesis”, which was confirmed in humans as of 1994. Epidemiological ecological studies in the 1960 s showed significant associations between dietary animal protein and mortality from cardiovascular disease. However, animal protein intake was also significantly correlated with saturated fatty acid and cholesterol intake. In the last decades two prospective cohort studies demonstrated a decreased cardiovascular risk in women during high- versus low-protein intake when adjusting for other dietary factors (e. g., saturated fats) and other cardiovascular risk factors. A direct cholesterol lowering effect of proteins has not been shown. Despite earlier research indicating that soy protein has cardioprotective effects as compared to other proteins, these observations have not been confirmed by randomized placebo-controlled trials. However, most experts recommend the consumption of foods rich in plant proteins as alternatives to meat and dairy products rich in saturated fat and containing cholesterol. There are no scientific arguments to increase the daily protein intake to more than 20 % of total energy intake as recommended by the guidelines, in order to improve cardiovascular health.

The World

Obesity has emerged as the most potential cardiovascular risk factor and has raised concern among public and their health related issues not only in developed but also in developing countries. The Worldwide obesity occurrence has almost has gone three times since 1975. Research suggests there are about 775 million obese people in the World including adult, children, and adolescents. Nearly 50% of the children who are obese and overweight in Asia in are below 5 years. There is a steep incline of childhood obesity when compared to 1971 which is not only in developed countries but also in developing countries. A considerable amount of weight gain occurs during the transition phase from adolescence to young adulthood. It is also suggested that those adultswho were obese in childhood also remained obese in their adulthood with a higher metabolic risk than those who became obese in their adulthood. In India, the urban Indian female in the age group of 30-45 years have emerged as an 〝at risk population” for cardiovascular diseases. To understand how obesity can influence cardiovascular function, it becomes immense important to understand the changes which can take place in adipose tissue due to obesity. There are two proposed concepts explaining the inflammatory status of macrophage. The predominant cause of insulin resistance is obesity. Epidemiological and research studies have indicated that the pathogenesis of obesity-related metabolic dysfunction involves the development of a systemic, low-grade inflammatory state. It is becoming clear that targeting the pro-inflammatory pathwaymay provide a novel therapeutic approach to prevent insulin resistance, particularly in obesity inducedinsulin resistance. Some cost effective interventions that are feasible by all and can be implemented even in low-resource settings includes - population-wide and individual, which are recommended to be used in combination to reduce the greatest cardiovascular disease burden. The sixth target in the Global NCD action plan is to reduce the prevalence of hypertension by 25%. Reducing the incidence of hypertension by implementing population-wide policies to educe behavioral risk factors. Reducing cigarette smoking, body weight, blood pressure, blood cholesterol, and blood glucose all have a beneficial impact on major biological cardiovascular risk factors. A variety of lifestyle modifications have been shown, in clinical trials, to lower bloodpressure, includes weight loss, physical activity, moderation of alcohol intake, increased fresh fruit and vegetables and reduced saturated fat in the diet, reduction of dietary sodium intake, andincreased potassium intake. Also, trials of reduction of saturated fat and its partial replacement by unsaturated fats have improved dyslipidaemia and lowered risk of cardiovascular events. This initiative driven by the Ministry of Health and Family Welfare, State Governments, Indian Council of Medical Research and the World Health Organization are remarkable. The Government of India has adopted a national action plan for the prevention and control of non-communicable diseases (NCDs) with specific targets to be achieved by 2025, including a 25% reduction inoverall mortality from cardiovascular diseases, a 25% relative reduction in the prevalence of raised blood pressure and a 30% reduction in salt/sodium intake. In a nutshell increased BMI values can predict the nature of obesity and its aftermaths in terms inflammation and other disease associated with obesity. It’s high time; we must realize it and keep an eye on health status in order to live long and healthy life.

Introduction: Few studies have evaluated the association between type and amount of dietary protein intake and clinically evident cardiovascular disease, with inconsistent findings, and no study has investigated the association between type and amount of dietary protein intake and subclinical coronary atherosclerosis. Hypothesis: We examined the associations of total, animal, and vegetable protein intakes with coronary artery calcium (CAC) in a large population of asymptomatic adults. Methods: We performed a cross-sectional study of 29,034 asymptomatic young and middle-aged adults (mean age 41.6 years; males 80.3%) who are free of clinically evident cancer or cardiovascular disease. All participants underwent a health screening examination including cardiac computed tomography for CAC scoring and completed a food frequency questionnaire at the Kangbuk Samsung Hospital Total Healthcare Centers in Seoul and Suwon, South Korea from March, 2011 to April, 2013. Protein intake and other nutrient intake were adjusted for total energy intake using the residual method. Multivariable-adjusted CAC score ratios and 95% confidence intervals (CIs) were estimated by robust Tobit regression models for natural logarithm (CAC score + 1). Results: The proportion of study participants with detectable CAC (CAC score > 0) was 13.4 %. After adjustment for total energy intake, other nutrient intake, and potential confounding factors, we found an increased prevalence of CAC with higher animal protein intake, but not with total and vegetable protein intakes. In multivariable-adjusted models, CAC ratios (95% CIs) comparing the highest with the lowest quintiles were 1.82 (1.09-3.04; P for trend = 0.01) for animal protein intake, 1.25 (0.87-1.81; P for trend = 0.13) for vegetable protein intake, and 1.19 (0.74-1.93; P for trend = 0.59) for total protein intake. Conclusion: High animal protein intake, but not total or vegetable protein, was associated with an increased prevalence of subclinical coronary atherosclerosis and with a greater degree of coronary calcification.

ABSTRACT Background The potential cardiovascular impact of dietary cholesterol intake has been actively debated for decades. Objectives We aimed to evaluate associations of dietary cholesterol and egg intakes with incident cardiovascular disease (CVD) and all-cause and cause-specific mortality. Methods We included 96,831 US postmenopausal women aged 50–79 y without known CVD or cancer during baseline enrollment (1993–1998) of the Women's Health Initiative. Dietary information was collected using a validated FFQ. Incident CVD [i.e., ischemic heart disease (IHD) and stroke] and all-cause and cause-specific mortality were ascertained and adjudicated through February 2018. Results A total of 9808 incident CVD cases and 19,508 all-cause deaths occurred during a median follow-up of 17.8 y and 18.9 y, respectively. After multivariable adjustment for traditional risk factors and key dietary nutrients including dietary saturated fat, there were modest associations of dietary cholesterol intake with incident CVD (HRQ5versusQ1: 1.12; 95% CI: 1.03, 1.21; P-trend < 0.001) and all-cause mortality (HRQ5versusQ1: 1.09; 95% CI: 1.02, 1.15; P-trend < 0.001). Significant positive associations were also observed between dietary cholesterol and incident IHD (P-trend = 0.007), incident ischemic stroke (P-trend = 0.002), and CVD mortality (P-trend = 0.002), whereas there was an inverse association for incident hemorrhagic stroke (P-trend = 0.037) and no association for mortality from cancer, Alzheimer disease/dementia, respiratory diseases, or other causes (P-trend > 0.05). Higher egg consumption was also associated with modestly higher risk of incident CVD (P-trend = 0.004) and all-cause mortality (P-trend < 0.001), with HRs of 1.14 (95% CI: 1.04, 1.25) and 1.14 (95% CI: 1.07, 1.22), respectively, when comparing ≥1 egg/d with <1 egg/wk. Conclusions Both higher dietary cholesterol intake and higher egg consumption appeared to be associated with modestly elevated risk of incident CVD and all-cause mortality in US postmenopausal women.

The Impact

The impact of diet on cardiovascular disease has become an increasingly relevant topic as ongoing epidemiological evidence continues to demonstrate clear associations with disease burden and mortality. Certain diets, such as those high in sodium and saturated fat, are associated with cardiovascular disease states, while other diets can be cardioprotective. However, there is limited knowledge on how the micro- and macronutrients within such cardioprotective diets afford their benefits. One such micronutrient is the catechin class, which are naturally occurring compounds in plant foods, such as teas, cocoa, wine, pears, and apples. Recent evidence reveals that catechins may be a key mediator in cardiovascular health via mechanisms of blood pressure reduction, flow-mediated vasodilation, and atherosclerosis attenuation. This review evaluates the current literature on the interplay between catechins and cardiovascular disease, which may have important implications for nutrition counseling and pharmaceutical drug development.

Abstract Background Hypertensive disorders of pregnancy (HDP) affect 5–10% of pregnant women. Women after HDP have 2–3 times increased risk of heart attack, stroke and diabetes, as soon as 5–10 years after pregnancy. Australian healthcare providers’ knowledge of cardiovascular disease (CVD) risks for women after HDP is unknown, and this study aimed to explore their current knowledge and practice regarding long-term cardiovascular health after HDP, as a precursor to producing targeted healthcare provider education on health after HDP. Methods A custom-created, face-validated online survey explored knowledge about long-term risks after HDP. Distribution occurred from February to July 2019 via professional colleges, key organisations and social media. The objective was to assess current knowledge and knowledge gaps amongst a group of healthcare providers (HCP) in Australia, regarding long-term cardiovascular health after hypertensive disorders of pregnancy (HDP), specifically gestational hypertension or preeclampsia. Results Of 492 respondents, 203 were midwives, 188 obstetricians, 75 general practitioners (GP), and 26 cardiologists. A risk knowledge score was computed with 0–6 considered low, 6.1–8.9 moderate and 9–12 high. Most participants (85%) were aware of increased cardiovascular disease after preeclampsia and gestational hypertension (range 76% midwives to 100% cardiologists). There were significant differences in average knowledge scores regarding health after preeclampsia; high for cardiologists (9.3), moderate for GPs and obstetricians (8.2 and 7.6 respectively) and low for midwives (5.9). Average knowledge scores were somewhat lower for gestational hypertension (9.0 for cardiologists, 7.4 for obstetricians and GPs, 5.1 for midwives). Knowledge was highest regarding risk of chronic hypertension, moderate to high regarding risk of ischaemic heart disease, stroke and recurring HDP, and low for diabetes and peripheral vascular disease. Only 34% were aware that risks start < 10 years after the affected pregnancy. Conclusion(s) Participants were aware there is increased cardiovascular risk after HDP, although less aware of risks after gestational hypertension and some specific risks including diabetes. Findings will inform the development of targeted education.

Introduction: While saturated fat (SFA) intake has long been considered as an important risk factor for cardiovascular disease (CVD), some evidence in recent years has called these findings into question. There is limited evidence examining the separate effects of SFAs from different food sources on cardiovascular risk. Objective: The goal of this study was to determine whether higher (vs. lower) intakes of SFA from dairy and non-dairy sources were associated with risk of incident cardiovascular disease. Methods: Data from 1991 adults, ages 30 and older, who were free of CVD at the time of baseline dietary assessment in the prospective Framingham Offspring Study were included in these analyses. Dairy and non-dairy SFA was assessed using 3-day diet records at exams 3 and 5; intakes were adjusted for body weight using the residual method. Subjects were followed from exam 5 to exam 9 for CVD events (median follow-up 16.9 years). Cox proportional hazards models were used to adjust for confounding by sex, age, BMI, physical activity, smoking (pack-years), non-dairy SFA (in dairy SFA models, and vice versa for non-dairy models), and time dependent occurrence of hypertension or use of lipid-lowering medications. Results: Subjects were classified into 3 categories of sex-specific intake of dairy SFA (<9, 9-<13, and ≥13 g/day for men; <6, 6-<9, ≥9 g/day for women) and non-dairy SFA (<15, 15-<18 and ≥18 g/day for men; <12, 12-<15, and ≥15 g/day for women). Women with moderate (vs. low) and high (vs. low) dairy SFA intakes had 56% (95% CI: 0.27-0.71) and 20% (95% CI: 0.56-1.14) lower CVD risks, respectively, while women consuming high (vs. low) non-dairy SFA had 22% (CI: 0.52-1.16) lower risks. Neither dairy-based SFA nor non-dairy SFA intake was associated with CVD occurrence in men. To determine whether the combined effects of SFA from dairy and non-dairy sources were associated with CVD risk, we cross-classified SFA intakes from the two sources (i.e., high/low dairy SFA intake: <9 vs. ≥9 g/day for men, <6 vs ≥6 g/day for women; high/low non-dairy SFA intake: <15 vs. ≥15 g/day for both men & women). Overall, subjects with higher intakes of dairy SFA combined with lower intakes of non-dairy SFA had the lowest risks of CVD (HR:0.73; 95% CI: 0.54-0.98). These effects were stronger in women (HR:0.60; 95% CI: 0.41-0.88), and non-statistically significant in men (HR: 0.88; 95% CI: 0.54-1.43). Women with higher combined intakes of SFA from both dairy and non-dairy sources still had 44% lower risks of CVD. However, higher intakes of SFA from non-dairy sources alone was not associated with CVD risk in either men or women. Conclusions: Saturated fats derived from dairy sources were associated with a reduced risk of incident CVD in women. For both men and women, those who had higher intakes of dairy-derived SFA combined with lower intakes of non-dairy SFA tended to have lower risks of CVD than those with lower intakes of SFA from both sources.

Background: Dietary intake is linked to numerous modifiable risk factors of cardiovascular disease. Current dietary recommendations in the UK to reduce the risk of cardiovascular disease are not being met. A genotype-based personalised approach to dietary recommendations may motivate individuals to make positive changes in their dietary behaviour. Aim: To determine the effect of a personalised nutrition intervention, based on apolipoprotein E ( ApoE, rs7412; rs429358) and methylenetetrahydrofolate reductase ( MTHFR, rs1801133) genotype, on reported dietary intake of saturated fat and folate in participants informed of a risk genotype compared to those informed of non-risk genotype. Methods: Baseline data ( n = 99) were collected to determine genotype (non-risk vs risk), dietary intake and cardiovascular risk (Q-Risk®2 cardiovascular risk calculator). Participants were provided with personalised nutrition advice via email based on their ApoE and MTHFR genotype and reported intake of folate and saturated fat. After 10 days, dietary intake data were reported for a second time. Results: Personalised nutrition advice led to favourable dietary changes, irrespective of genotype, in participants who were not meeting dietary recommendations at baseline for saturated fat ( p < 0.001) and folate ( p = 0.002). Only participants who were informed of a risk ApoE genotype met saturated fat recommendations following personalised nutrition advice. Conclusion: Incorporation of genotype-based personalised nutrition advice in a diet behaviour intervention may elicit favourable changes in dietary behaviour in participants informed of a risk genotype. Participants informed of a non-risk genotype also respond to personalised nutrition advice favourably but to a lesser extent.

AbstractObjectiveTo examine the association of total animal protein intake and protein derived from different dietary sources (meat; fish and shellfish; eggs; milk products) with global and abdominal obesity among adults in Luxembourg.DesignBinary logistic regression analysis was used to assess the relationship between animal protein intake (as a percentage of total energy intake) and global obesity (BMI≥30·0 kg/m2) and abdominal obesity (waist circumference ≥102 cm for men and ≥88 cm for women), after controlling for potential confounders.SettingObservation of Cardiovascular Risk Factors in Luxembourg (ORISCAV-LUX) study.SubjectsThe study population was derived from a national cross-sectional stratified sample of 1152 individuals aged 18–69 years, recruited between November 2007 and January 2009.ResultsThere was an independent positive association between total animal protein intake and both global (OR=1·18; 95 % CI 1·12, 1·25) and abdominal obesity (OR=1·14; 95 % CI 1·08, 1·20) after adjustment for age, gender, education, smoking, physical activity and intakes of total fat, carbohydrate, fibre, and fruit and vegetables. Protein intakes from meat, fish and shellfish were positively associated with global and abdominal obesity with further adjustment for vegetal protein and other sources of animal-derived protein (all P<0·01). Protein derived from eggs or milk products was unrelated to global or abdominal obesity.ConclusionsOur findings suggest that protein derived from animal sources, in particular from meat, fish and shellfish, may be associated with increased risk of both global and abdominal obesity among presumably healthy adults in Luxembourg. These findings suggest that lower animal protein intakes may be important for maintenance of healthy body weight.
