5 foods that helps the heart against diseases

Eating right is the key for lowering your risk to getting heart disease. Get started with these five (5) foods you should eat regularly that can help you prevent heart diseases.

1. Fruits and vegetables

An impressive number of studies have shown that abundant consumption of plant foods is associated with a reduced risk of coronary disorders. This effect is particularly significant for green vegetables, cruciferous vegetables (cabbage, broccoli, etc.), and those rich in vitamin C (green vegetables in general). Specifically, each daily portion of fruits and vegetables reduces the risk of coronary diseases by about 4 percent, which is an excellent reason to eat these foods as often as possible.

While all plants have a positive impact on the risk of cardiovascular disease, some stand out. For example, recent studies suggest that the consumption of broccoli is associated with a marked reduction in the risk of heart disease. This result concurs with observations from a pilot study showing that consumption of young broccoli stems (100 g per day for a week) reduces LDL cholesterol (bad cholesterol) and increases HDL cholesterol (good cholesterol). More recently, another study has shown that broccoli’s protective role could also be linked to its ability to improve the heart’s muscle function and protect it from damage caused by free radicals.

2. Whole grains

Who would believe that a change in lifestyle as simple as replacing everyday white bread with bread containing whole grains could reduce the risk of coronary disease and stroke by 40 percent? But it really can!

Whole grains are one of those foods whose remarkable impact on the prevention of chronic diseases is greatly underestimated. We are so accustomed to the presence of refined flour in almost all of our cereal products that we forget just how much this refining eliminates most of the beneficial constituents of the grain. Whole grains contain an abundance of antioxidants, minerals, vitamins, phytochemical compounds, and fibres present in both the bran (outside layer) and the germ (layer inside the bran). It is becoming increasingly clear that all these constituents act synergistically to prevent the development of heart disease.

3. Red wine

Red wine is a very complex product that contains several thousand chemical compounds, but it is generally acknowledged that the positive effects associated with moderate consumption of wine are mainly due to a molecule called resveratrol. This molecule, which is found in significant quantities only in red wine, has many positive effects on the cardiovascular system, including restricting the formation of blood clots that can block blood vessels, causing serious problems.

Red wine’s protective effect against heart disease has been well illustrated and is now called the “French paradox”: People who regularly drink red wine have quite a low mortality rate for heart disease, despite the presence of many risk factors such as smoking, hypertension, and high levels of blood cholesterol.

4. Green tea

Recent studies show that people who drink at least two cups of green tea a day (about 500 mL) have a 16 percent lower mortality rate than those who drink less. This effect is especially pronounced in women: While the mortality rate of men who are regular tea drinkers is reduced by 12 percent, that of females is 23 percent lower, resulting in a protective effect two times greater! This protective effect seems mainly due to a major reduction in mortality rates associated with coronary disease (25 percent) and especially with stroke (60 percent).

5. Chocolate


A recent study shows that people who regularly consume 70% dark chocolate (about 20 g per day) show a marked improvement in blood flow, while no improvement is observed in those who eat “processed” chocolate, which contains very little cocoa paste. It seems that the positive effect of dark chocolate is linked to a property in its polyphenols that releases a chemical messenger, nitric oxide, which increases arterial dilatation, at the same time improving blood flow and reducing platelet aggregation.

However, it is important to note that previous studies have shown that milk prevents the absorption of dark chocolate’s polyphenols, thereby neutralizing its beneficial effects. Milk contains large amounts of casein, a protein that interacts with polyphenols and prevents them from being efficiently absorbed by the intestine. It is therefore always preferable to consume dark chocolate unaccompanied by milk. A similar phenomenon is observed with tea: While consumption of tea leads to a significant improvement in the ability of arteries to dilate, which confirms that the polyphenols contained in tea have a positive effect on the cardiovascular system, adding milk completely reverses this effect and neutralizes its positive effects on the cardiovascular system.
