- A recent study indicates that consuming half an avocado twice a week can significantly reduce the risk of heart-related diseases, decreasing the risk of cardiovascular disease by 16% and heart disease by 21%.
- The study highlights the role of plant-sourced unsaturated fats in improving diet quality, with avocados being a rich source of such beneficial fats.
- The research does not definitively establish that avocado consumption causes a lowered risk for heart diseases; it simply suggests a possible correlation.
- Substituting half a daily serving of certain food items with avocado can reduce cardiovascular disease risk by 16% to 22%, but it does not additionally benefit when replaced with items like olive oil, nuts, or affect the risk of stroke.
- Avocados are a nutrient-rich food source providing essential compounds, healthy fats, vitamins, fiber, and critical minerals, which can help support a balanced, plant-based diet.
Findings from a recent study suggest that consuming half an avocado twice weekly can reduce the risk of heart-related diseases significantly. The study found that there was a decreased risk of cardiovascular disease by 16%, with heart disease risk dropping by 21% in comparison to individuals who seldom or never consume this fruit.
The Role of Plant-Based Unsaturated Fats
According to the lead investigator, Lorena Pacheco, the results further affirm the significance of plant-sourced unsaturated fats in improving diet quality. Pacheco, who is associated with the Department of Nutrition at a renowned public health school in Boston, believes that these types of fats are a critical element in the prevention of cardiovascular disorders in the broader population.
Given the notable surge in avocado consumption across the U.S. in the past two decades, Pacheco’s findings seem timely and pertinent.
Correlation, not Causation
Pacheco elaborates that this observational research can’t definitively prove that avocado consumption results in a lowered risk for cardiovascular diseases. Rather, it suggests a potential link. The implicated study received funding from two major U.S. National Institutes.
Avocados and Cardiovascular Health
While avocados can contribute to a heart-healthy diet, Pacheco emphasizes that they are not a standalone “magic bullet”.
Methodology and Limitations
The study was based on self-reported intake of avocados, which might have introduced some bias due to inaccurate recall. Data was collected from over 110,000 male and female participants, part of two major health studies.
Cardiovascular and Stroke Risk: Relevance of Avocado Intake
Over a follow-up period exceeding three decades, more than 9,100 individuals developed heart conditions, while over 5,200 experienced a stroke. The research further unveiled that substituting half a daily serving of substitutes such as margarine, egg, butter, yogurt, cheese, or processed meats with avocado can reduce cardiovascular disease risk by 16% to 22%.
However, if half a serving of avocado was used in place of items like olive oil, nuts, or other plant-based oils, there wasn’t any additional benefit. Also, the risk of stroke remained unaffected, irrespective of avocado intake frequency.
Health Benefits of Avocados
Avocado is a nutrient-rich food source, providing a bevy of essential compounds, including healthy fats, vitamins C and E, fiber, and critical minerals like potassium. They are naturally cholesterol-free, making them a crucial part of a balanced, plant-based diet.
A senior clinical nutritionist, Samantha Heller from NYU Langone Health in New York City, who was not related to the study, agrees on the many benefits of avocados. In her opinion, avocados can be a useful addition to a person’s balanced, plant-driven diet, due to its satiating taste and creamy texture.
Heller also shared some creative ways to incorporate avocados into daily meals. These include using avocados in a variety of dishes, from guacamole to avocado toast, and even preparing sweet treats like fudge with this versatile fruit.
The complete study was officially published online on March 30 in a widely-read health journal.
