According to a recent study, published in The Journal of Physiology, exercising four to five times per week may help stop the main arteries to the heart from stiffening up.
The researchers from the US have found that those who exercise four to five times per week had healthier large central arteries and healthier middle-sized ones.
Lead author of the study Dr. Benjamin Levine of the Institute for Exercise and Environmental Medicine in Dallas, USA, explains: “This work is really exciting because it enables us to develop exercise programs to keep the heart youthful and even turn back time on older hearts and blood vessels.”
Heart disease and stroke are very dangerous conditions and now more young people are being affected according to the third National Health And Morbidity Survey.
Unhealthy diet, rich in saturated/trans-fat, lack of fibre, excessive salt intake combined with the lack of activity increase the risk of cardiovascular diseases.
1. Follow the guiding principles of balance, moderation and variety
Eat all foods from the various groups of the food pyramid in moderate portions and choose from a variety of food items within each food group.
2. Eat more fiber
Fibre helps improve blood cholesterol levels, stabilise blood glucose levels, maintain healthy weight and lower the risk of CVD risk factors.
3. Be physically active
Physical activity, especially aerobic exercises, helps to strengthen the heart muscles, reduce stress levels, improve metabolism and increase the level of HDL cholesterol.
4. Keep a healthy body weight
Maintaining a healthy weight or reducing extra weight can significantly reduce the risk of CVD and its risk factors.
5. Screen for risk factors regularly
Every year you should check for blood pressure, cholesterol and blood glucose level.
6. Reduce stress and get enough rest
Stress is able to increase blood pressure. Try to have a eigh hours sleep and relax during the day.
7. Stop smoking if you do
Those who smoke a pack of cigarettes a day double their risk of heart attack compared to non-smokers.
Smokers who quit start to improve their heart health and reduce their risk for CVD immediately.

The scientists from Worcester Polytechnic Institute, USA, successfully used spinach leaves to create functioning human heart tissue with networks of veins able to transport blood.
The researchers used green plant material of spinach to grow samples of tissue, as cellulose from plants is great material to use due to its compatibleness with living tissues, low price, and availability. To access the fine vascular structure of spinach, the scientists circulated a detergent solution through the leaves to wash the plant cells away. Then they seeded the leaf vascular structure with heart muscle cells, and within a few days, they saw that the heart cells started contract like they would in human tissue.
The scientists explain in their paper: “Plants and animals exploit fundamentally different approaches to transporting fluids, chemicals, and macromolecules, yet there are surprising similarities in their vascular network structure.”
