  • High Fibre vs Low Fibre Diet

    Fiber is a type of carbohydrate that cannot be digested by the human body. Unlike other carbohydrates, such as starches and sugars, fiber consists of complex chains of sugar molecules that are bonded together in a way that our digestive enzymes cannot break down.

    When we consume fiber, it passes through the digestive system relatively intact, without being broken down into individual sugar molecules. Instead of being absorbed into the bloodstream like other carbohydrates, fiber moves through the digestive tract and ultimately gets eliminated from the body.

    There are two main types of fiber: soluble fiber and insoluble fiber. Soluble fiber dissolves in water and forms a gel-like substance in the digestive tract, while insoluble fiber does not dissolve in water and adds bulk to the stool.

    Fiber plays an essential role in regulating various bodily functions, including the regulation of blood sugar levels and hunger. Here's how it works:

    1. Blood sugar regulation: Soluble fiber, such as that found in oats, legumes, and some fruits, can slow down the absorption of sugars from the digestive tract into the bloodstream. This slower sugar release helps prevent rapid spikes in blood sugar levels, promoting more stable and controlled glucose metabolism.

    2. Hunger control: Fiber-rich foods tend to be more filling than low-fiber foods. This is because fiber adds bulk to the diet, increasing satiety and reducing overall calorie intake. Additionally, some types of soluble fiber can delay stomach emptying, making you feel fuller for longer periods.

    Incorporating an adequate amount of fiber into your diet is generally recommended for maintaining a healthy digestive system, promoting regular bowel movements, managing weight, and supporting overall well-being. It is often advised to consume a variety of fiber sources, including whole grains, vegetables, fruits, legumes, nuts, and seeds, to benefit from both soluble and insoluble fiber.

  • High Fibre vs Low Fibre Diet

    A high fiber diet is generally beneficial for overall health and can help protect against certain diseases like heart disease, stroke, and certain cancers. It also aids in digestion. There are two types of fiber: insoluble fiber, found in whole grains, vegetables, and fruits, and soluble fiber, found in vegetables, fruits, oats, and legumes. Most foods contain a combination of both types of fiber, but some are higher in soluble fiber while others are higher in insoluble fiber.

    For a high fiber diet, it is recommended to consume about 25 to 35 grams of fiber per day. This can be achieved by incorporating high fiber foods into all meals and snacks throughout the day, including whole grains, a variety of vegetables, and fruits.

    However, if you have digestive issues such as irritable bowel disease with flare-ups, you may benefit from a low fiber diet during certain phases. A low fiber diet typically involves consuming less than 10 grams of fiber per day, which is a significant reduction from a high fiber diet.

    When following a low fiber diet, it is advisable to avoid whole grains and instead opt for refined products such as pastas, breads, bagels, and crackers made from refined flour. Choosing white rice over brown rice is also recommended. While it's not necessary to eliminate vegetables and fruits completely, it's best to choose cooked vegetables and fruits in the form of applesauce, as cooking reduces their fiber content. Cruciferous vegetables like broccoli, Brussels sprouts, kale, and cabbage should be avoided as they are high in fiber.

    If you believe you would benefit from a low fiber diet, it is advisable to consult with a local family physician or a physiotherapist, along with a registered dietitian and athletic therapist. They can provide personalized guidance and help you manage your condition effectively. Incorporating regular exercise and maintaining a balanced diet are also important for overall health.

    Please note that the advice provided here is general and it's always best to consult with a healthcare professional or a registered dietitian for personalized dietary recommendations based on your specific health condition and needs.
