If you have been diagnosed with diabetes or pre-diabetes you might be familiar with the concept of GI (glycaemic index).
GI ranks foods on how fast are digested into sugars and how quickly it impacts blood glucose levels, but it does not reflect the portion size.
The GL (Glycaemic load) combines both the quantity and quality of
Carbohydrates, reflecting the amount of carbohydrates a food contains and its GI.
In other words, the GI – is how quick, and the GL – how much and how quick, so is a better parameter to understand the impact of foods on blood glucose levels.
The effects on your health
Foods with a low GL help maintaining stable blood glucose levels, avoiding the dreaded ‘blood sugar roller-coaster’ manifesting as sugar rush followed by a crush. This impacts energy levels as stable blood glucose levels translates as consistent energy levels and a more levelled mood.
If diagnosed with diabetes or pre-diabetes choosing low GI/GL foods is a must to manage the condition, but also no diabetic people can benefit in choosing mainly low GI/GL food to help preventing type2 diabetes, better weight management and increase energy levels.
What Affects the GI/GL of a Food?
*Fibre and fat tend to lower the GI of a food. Having a whole orange is better than orange juice, because of the fibre content, or adding a source of fat like avocado to bread will lower its GI.
* Processing. The more carbohydrates are broken down, the quicker will spike blood glucose. For example, a mashed potato has a higher GI than a whole baked potato.
* Cooking method. Cooking a food for longer increases breakdown of carbohydrates. For example, al dente pasta has a lower GI than soft-cooked pasta.
3 easy tips to lower GI in your meals
*Make sure there is always a source of fibre in each meal. Adding spinach to breakfast, a side salad with your main meals and adding as many vegetables as possible to cooked dishes.
*Legumes are also an excellent source of fibre, and their blood sugar stabilising effects lingers until the meal after the one they have been consumed. Is a good idea to include them in your lunch to have stable blood sugar levels for the whole day. An idea could be adding hummus to a salad, have a chilli con carne with black beans in it, or a minestrone with a variety of beans.
*Avoid tropical and over-ripped fruit as those have a very high GI. Swap then for berries and apples, fruits with a low GI/GL.
Mast Cell Activation Syndrome (MCAS) is a condition in which the body’s mast cells—a type of white blood cell that plays a role in immune response—become overactive. When triggered, these cells release chemical mediators like histamines, which can lead to widespread inflammatory symptoms. Many people with MCAS experience histamine intolerance or sensitivity, which often exacerbates…
High testosterone levels in women can lead to weight gain, especially around the belly. This is common in conditions like polycystic ovary syndrome (PCOS), menopause, and from certain types of birth control. The key to managing this is balancing hormones and improving insulin resistance, which can be done through proper nutrition and supplements. Testosterone and…
What is Gluten? Gluten is a group of proteins found in certain grains, primarily wheat, barley, and rye. These proteins, known as gliadin and glutenin, are responsible for the elasticity of dough, helping it rise and maintain its shape. Gluten is what gives bread its chewy texture and helps it hold together. It’s not just…
