A special diet to soften blood vessels
The overall improvement in health associated with weight loss, especially the risk of cardiovascular disease, is directly related to weight loss. However, a recent study presented at the European Obesity Congress in Maastricht, the Netherlands, shows that three specific nutrients are especially helpful in improving your heart health as your blood vessels become more elastic.
People who are overweight have an increased risk of arterial stiffness, which results in decreased blood flow due to loss of elasticity of the arterial walls; then it is difficult for them to expand and contract properly. This hardening of the arteries increases the risk of heart disease and promotes atherosclerosis (blockage of the arteries by lipids).
You may need to lose weight, but it is It is also important to review your diet to reduce the cardiovascular risk associated with being overweight.. To do this, a recent study by Israeli researchers provides some ideas on how to guide us towards a diet that will promote vascular flexibility and thus better health.
Mediterranean diet rich in protein, zinc and niacin
The researchers observed 72 participants with metabolic syndrome and obesity (men and women, with an average age of 53 years) who underwent an intensive weight loss program for one year. A year later, the total BMI of participants fell by almost 10% on average. – Three parameters affecting vascular flexibility were measured. Among the participants who observed an improvement in one of these parameters, we found constants that allowed us to recommend three nutrients:
- Zinc plays a key role in helping to relax muscles in the blood vessels: allows them to expand and thus do their job better. Zinc is especially found in sunflower seeds, pumpkin seeds, seafood, veal liver, thyme, sesame seeds and many types of meat such as stewed beef or ground beef.
- Proteins to improve the thickness of the intimal medium of the common carotid artery – a marker of cardiovascular risk. The foods that contain the most are meat, milk, soy, eggs, cod, certain cheeses like parmesan or even peanuts and almonds.
- Niacin (or vitamin B3) known to dilate blood vessels, mainly in the upper body. It is mainly found in meat and fish.

Brurya Tal from Tel Aviv Sourasky Medical Center (Israel), lead author of the study: A Mediterranean diet rich in protein (low-fat dairy products, fish, poultry and eggs), rich in vegetables, nuts, seeds and moderate consumption of fruit and grains can help improve vascular flexibility and thus indirectly protect the cardiovascular system. system. »
