In 1974, the first edition of Robbins' Pathologic Basis of Disease alerted us to the fact that most chronic conditions were associated with inflammation (1). This fact is described regularly in scientific journals and most commonly in association with heart disease (2). However, other conditions are associated with chronic inflammation and this includes disorders of the gastrointestinal tract, and it is now recognized that chronic subclinical intestinal inflammation is a common feature in ankylosing spondylitis, rheumatoid arthritis, and other rheumatic conditions (3). The increase in systemic inflammation associated with aging is also thought to be driven, in part, by chronic intestinal inflammation (3).
The gut has very basic needs in order to remain healthy. Essentially, the gut depends on the presence of fiber-rich foods, especially vegetables and fruit. A diet without fiber and one that is excessive in sugar and starch, encourages the development of inflammation, constipation, and dysbiosis.
To restore gut function and promote systemic health, the appropriate aforementioned foods should be consumed and supported by key supplements. Most important is to replenish the gut with healthy bacteria called probiotics - Lactobacillus acidophilus and Bifidobacterium are the most common. Indeed, healthy aging is thought to be associated with a healthy intestinal microbiota (3).
Fiber is a crucial component in the diet and the average American consumes less than 50% of the recommended level. Fiber supplementation is an excellent way to improve intestinal health and reduce the expression of diverse intestinal conditions (4).
Supplemental digestive enzymes are very beneficial for individuals as they transition to a healthy diet. Short-term use is typically recommended while probiotics and fiber can be used as part of a healthy lifestyle.
