Oral Health and Overall Health The oral cavity is the starting point of our digestive tract, masticating and breaking down our food so we can begin to get nutrients. Beyond that, it is the first point of exposure to many pathogens; this vulnerability means we have developed the physiology and structure to keep us protected. We are going to review why oral health contributes to overall health and what you can do to fortify your first line of defense. Risky Business Our mouths and throat are designed to optimise function, meaning improve digestion and prevent infection. Most people associate our

While our bodies are finely tuned, energy efficient, high power, recycling machines, waste is still created. Some waste is simply produced when there is an excess of a nutrient or molecule that our body does not, or cannot, use or store. Some is produced by our cells as they make more energy, or as by-products of regular cell functioning. With each process, our body must do something with the waste – either recycle it or get rid of it, as holding on to these wastes products can be detrimental. Waste products can create a toxic soup within tissues, preventing healthy cells from functioning normally, producing a buildup of free radicals in our cells, and even cause premature cell death. Luckily, our body has adapted not one but four methods of excreting such wastes, through the bowels, kidneys, skin, and lungs.
Bowel Movements: What’s considered normal?
The process of breaking down food is complicated and requires both mechanical and chemical breakdown. To facilitate this breakdown our body enlists the help of acids, enzymes, and bacteria to help extract all of the usable nutrients. What remains in the gut is everything that could not be used.
The appearance of stool, including shape, color, consistency, size, frequency, and urgency of bowel movements can provide insight into each stage of digestion.
- A normal bowel movement should occur a few hours after a meal, providing ample time for nutrients to be absorbed, with minimal urgency.
- If bowel movements are too frequent there may not be enough time to digest and absorb key nutrients. o If there is too much urgency there may be an issue with the rectal muscle tone or neural signaling.
- The volume of the stool will vary based on the volume consumed and size of an individual; however, 200g/day (about a cup of butter) is quite normal. A small volume means that there is not enough weight to stimulate the smooth muscles of the GI tract to contract (this contraction is known as peristalsis). A small volume may also reflect malnutrition or lack of bulking factors, such as fibre or water, in the diet. A higher volume may point to overfeeding or malabsorption.
Tomorrow we will explore other routes of elimination in this blog post series so stay tuned!
