27 May 2019 --- Heart health patients who consume higher amounts of fiber tend to have a healthier gut microbiome, which is linked to a reduced risk of death or need of a heart transplant. This is according to a study presented yesterday at Heart Failure 2019, a scientific congress of the European Society of Cardiology (ESC). The researchers note that the findings should be further explored and that should they be confirmed, foods high in fiber such as cereals, fruits and vegetables should be chosen to stimulate a healthy gut flora.
