Study: Bananas and avocados protect against cardiovascular disease

Every day a banana and an avocado against hardening of the arteries?

If people ingest an inadequate amount of potassium every day, it can cause serious health problems. Due to the lack of potassium, those affected even threaten dangerous cardiovascular diseases. However, there is an easy way to avoid this. The consumption of only one banana and one avocado a day is sufficient to prevent hardening of the arteries, which can later lead to a dramatic heart disease.

The University of Alabama scientists found in a recent study that daily consumption of just one banana and one avocado can protect against dangerous heart disease. The experts published the results of their study in the journal "JCI Insight".

Certain foods contain a lot of potassium. Such foods include, for example, bananas and avocados. Researchers have now discovered that consuming banana and avocado daily leads to important health benefits. A diet that is high in potassium protects against arteriosclerosis and hardening of the arteries and thus also against dangerous cardiovascular diseases.(Photo: Brent Hofacker /

When foods contain lots of potassium, they can reduce vascular calcification

The current study looked at how potassium-rich foods can prevent hardening of the arteries and reduce onset of vascular calcification. The physicians noted that even the consumption of a banana and an avocado is sufficient to avoid many heart diseases. In addition, the reduction of vascular calcifications had far-reaching effects on the likelihood of heart and kidney disease, the researchers explain. A diet that is high in potassium can also reduce the risk of a so-called aortic stenosis. Aortic stenosis is a common heart valve defect that is one of the classic cardiovascular risk factors.

What are vascular calcifications?

vascular calcifications usually occur when calcium begins to accumulate in body tissue, blood vessels or organs. Such an accumulation of calcium can cause normal processes of the body to be disturbed and the arteries to harden, the experts say.

How does potassium affect the risk of atherosclerosis?

The results of the study show the benefit of providing sufficient potassium to prevent vascular calcification in atherosclerosis susceptible mice, according to author Professor Paul Sanders of the University of Alabama. Of course, the adverse effect of low potassium intake was also observed in the study. The so-called hardening or stiffening of the arteries is commonly known as arteriosclerosis. It also affects how hard the heart has to work to pump blood through the body.

The experimental animals received three different amounts of potassium in their diet

The University of Alabama research team analyzed the effects of diets with different potassium concentrations in their study on mice. These experimental animals were given food containing either low, normal or high levels of potassium.

Potassium Affects Arterial Cure

The results found suggest that in the mice fed a low-potassium diet, arterial hardening was significantly more frequent compared to diet-fed animals. Such animals generally had significantly less arterial stiffening.

potassium reduces hardening of the aortic body's main artery

Mice with a potassium-rich diet have also been shown to have reduced stiffening in the main artery of their aortic body. This effect may be due to a low level of potassium in the blood, which prevents the expression of genes that maintain arterial flexibility, the researchers say.(as)
