High blood pressure is a dangerous condition that often leads to serious and sometimes fatal consequences. If you have been diagnosed with pre-high blood pressure it’s critical that you act immediately before the condition worsens into full-blown high blood pressure. If you already have high blood pressure, you should know that high blood pressure management is possible. Here are some tips for maintaining healthy blood pressure. 1. Quit Smoking There are lots of reasons to quit smoking, but did you know smoking increases the risk of high blood pressure? The very best thing you can do for your health is

Dietary fiber plays an important role in maintaining gut health and function. Fiber is useful in helping feel full after meals, ensuring our bowel movements are regular as well as stimulating the growth of healthy bacteria to allow the gut microbiome to thrive. It is important that fiber, both soluble and insoluble, is included in everyday consumption to ensure optimal gut health (1). These fibers are found in a variety of different foods as well as prebiotic and full fiber supplements that can be used in times of bowel irregularity or for general health and maintenance.
Fiber for healthy bowel movements
Insoluble fibers are traditionally found in higher amounts in vegetables, wheat, and most grains. They have the remarkable capacity to hold water and to bulk up stool, resulting in more gentle bowel movements that are softer, reducing incidents of constipation as well as the abdominal straining. Reduction in abdominal straining is particularly important as straining is thought to potentially result in increased incidents of haemorrhoids, varicose veins as well as pressure related changes to the bowel known as diverticula.
Useful in both diarrhea and constipation
One of the most interesting things to know about fiber is how it can alter the speed of transit of bowel contends depending on the situation. We’ve already discussed how insoluble fiber can help improve stool softness and increase transit time in times of constipation; it is important to note that soluble fiber can also do this to a lesser extent. In times of undesired loose bowel movements or diarrhea, insoluble fiber helps slow transit time so that loose stools can become more bulky.
Insoluble fiber is also used as fuel for the bacteria found in the colon, stimulating growth of a number of beneficial bacteria that ferment the fiber to form short chain fatty acids that improve the health of surrounding bowel and lower the pH of the intestine to improve gut flora (2). One type of insoluble fiber, Xylooligosaccharide (XOS), is particularly useful as a prebiotic that promotes growth of Bifidobacterium –important inhabitants of healthy guts known for helping provide stability and prevention of disease (3). XOS is also able to lower cholesterol, improve blood sugar as well as absorption and production of B-complex vitamins (2).
Fiber to feel full
Soluble fiber, found in fruits, oats, barley as well as legumes, can combine with liquids to form a gel that slows gastric emptying. This gel can help activate stretch receptors in the stomach, providing a pronounced feeling of fullness which can decrease overeating. Soluble fibers are also especially useful in their ability to lower blood cholesterol by reducing fat abortion.
Fiber to improve blood sugar
Both soluble and insoluble fibers have been shown to improve glycaemic control and reduce cholesterol in those with type 2 diabetes mellitus (4). Those that consumed a diet rich 50 g of fiber per day (fruits, vegetables, grains and legumes) for six weeks had significant improvements in their fasted blood glucose levels and urinary glucose levels. It was recommended that 50% of the fiber be soluble to help ensure that overconsumption of carbohydrates was limited and to delay gastric emptying so that carbohydrate levels in the small intestine were more consistent over time without quick increases.
