Probiotics : a matter of the Heart

Well Being| Views: 2498

The merits of probiotics are known for intestinal transit, the immune system and several other aspects of well-being. It’s encouraging to learn that they would also bring benefits to the heart! Although cardiovascular disease is the second leading cause of death in Canada, it is often preventable1. The reality is that 90% of Canadians aged 20 and older have at least one risk factor for heart disease2.

Reducing levels of bad cholesterol and controlling blood pressure

Prolonged probio-therapy (more than one year) would significantly reduce blood cholesterol. The strains demonstrating the greatest hypolipidemic effect are Bifidobacteria and Lactobacilli (particularly L. acidophilus)3,4. Studies show that probiotics also allow for a modest decrease in blood pressure, especially mixtures of strains in daily doses of more than 10 million bacteria, for at least 2 months5.

In addition to reducing your waist size and controlling your weight

Some bacterial strains prevent the absorption of dietary fat in the digestive tract, others provide more satiety, while others help to burn a little more calories. A study of obese women who took a supplement of Lactobacillus rhamnosus for more than 6 months showed that they lost more weight (and especially fat) than those who did not consume this probiotic6.

True or False? Adopting a modified fat diet is also indicated to reduce blood cholesterol beyond supplementation.

True. It would actually be ideal to combine the intake of probiotics and a low-fat diet in bad saturated fats and rich in good unsaturated fats.
