Green light for heart health: the portfolio diet lowers the CVD risk
In an extensive study, the influence of a plant-based nutritional pattern, known as the portfolio diet pattern, was examined for the risk of cardiovascular diseases (CVD). This nutritional pattern emphasizes the consumption of certain cholesterol -lowering foods, including vegetable protein, nuts, gel -forming fibers (viscose fibers), phytosterole (vegetable substances that are similar to cholesterol) and unsaturated fatty acids from plants. In the study, data from over 200,000 participants, both women and men who work in health professions and at the beginning of the study neither CVD nor cancer were treated and evaluated over a period of up to 30 years.
The results clearly show that people who adhered to this portfolio diet pattern had a lower risk of cardiovascular diseases, including a lower risk of coronary heart disease (CHD) and stroke. Interestingly, there was also a positive effect on the blood lipid profile and inflammatory marker, which indicates a generally improved state of health.
These results could have significant effects on public health and nutritional guidelines because they underline the advantages of a plant-based nutritional pattern to prevent cardiovascular diseases. In the future, such findings could lead to eating nutritional recommendations to promote the consumption of plant food in order to reduce the risk of CVD.
basic terms and concepts:
- CVD (cardiovascular diseases): A group of diseases that affect the heart and blood vessels, including stroke and coronary heart disease.
- portfolio diet pattern: A nutritional pattern that includes specific plant-based foods that are known from which they can lower cholesterol levels.
- phytosterole: vegetable substances, the structure of which is similar to cholesterol and which can help lower the cholesterol level in the blood.
- viscose fibers: A kind of fiber that can form a gel in the digestive tract and contributes to regulating cholesterol and blood sugar levels.
- coronary heart disease (CHD): an illness caused by the narrowing of coronary arteries, which leads to a limited blood supply to the heart.
- stroke: A medical emergency that occurs when the blood supply to part of the brain is interrupted.
connection between portfolio diet score and reduced risk of cardiovascular diseases
The implementation of an extensive prospective cohort study, including participants from the Nurse 'Health Study, the Nurses' Health Study II and the Health Professionals Follow-Up, provided significant knowledge about the effects of a plant-based portfolio diet on the risk of cardiovascular diseases (CVD), including coronary heart disease (CHD) and stroke. This study aimed to examine the long-term effects of the portfolio diet-characterized by a high absorption of plant proteins, nuts, viscoses fibers, phytosterols and vegetable simply unsaturated fats-for CVD susceptibility.
methodology
By using validated food fragments in the start of the output and then every four years, the portfolio diet score (PDS) was evaluated. The PDS evaluates the absorption of plant protein, nuts and seeds, viscous fiber sources, phytosterols and sources for vegetable simply unsaturated fats. Foods with high saturated fat and cholesterol have been assessed negatively. 73,924 women from the Nurses 'Health Study (1984-2016), 92,346 women from the Nurses' Health Study II (1991-2017) and 43,970 men from the Health Professionals Follow-up Study (1986-2016) who did not have CVD or Cancer at the beginning of the study.
results
In the course of up to 30 years of follow-up, 16,917 cases of CVD were documented, including 10,666 cases of CHD and 6,473 strokes. After multivariater adaptation to lifestyle factors and a modified alternate healthy eating index (except overlapping components), participants in the highest quintile of the PDS showed a reduced risk for CVD (Pooled Hazard Ratio [HR], 0.86 [95% CI, 0.81-0.92]; <0.001), CHD (pool HR, 0.86 [95% CI, 0.80-0.93]; An increase in the PDS by 25 percentages was with a lower risk for CVD (Pooled HR, 0.92 [95% CI, 0.89-0.95]), CHD (Pooled HR, 0.92 [95% CI, 0.88-0.95]) and stroke (Pooled HR, 0.92 [95% CI, 0.87-0.96]) associated. These results remained consistent in the sensitivity and most subgroup analyzes, and there was no evidence of a deviation from the linearity for CVD, CHD or stroke. In a sub-group of participants, a higher PDS was connected to a cheaper blood fat and inflammatory profile.
conclusions
The results underline that a higher adherence to the portfolio diet is associated with a lower risk of CVD, including CHD and stroke, as well as a cheaper blood fat and inflammatory profile. These findings complement the existing literature by providing detailed evidence of the advantages of long-term changes in diets as part of the portfolio diet and thus showing a promising approach for the prevention of CVD.
