Inflammation is often described as the underlying cause of many chronic diseases, and surprisingly, sugar can be a major trigger.
Acute vs Chronic Inflammation
Inflammation has become a bit of a buzzword, and for good reason, as it's linked to nearly all chronic illnesses today.
Inflammation is a natural bodily response to injury or trauma, helping the body heal. When you bruise your thumb or twist your ankle, chemical messengers are released into the bloodstream to call on immune cells, which then attack and eliminate the cause of the inflammation. This leads to warmth, redness, tenderness, and swelling, all of which help initiate the healing process.
Most people think of inflammation as something temporary. Indeed, acute inflammation subsides as the body recovers. However, problems arise when inflammation lingers, becoming chronic. In this state, the very chemicals meant to protect you start harming your cells and tissues, potentially even damaging your DNA. When these inflammatory chemicals remain high for an extended period, it’s referred to as chronic inflammation.
Chronic inflammation has been linked to a wide range of health issues, including heart disease, autoimmune disorders, allergies, mood problems, chronic pain, digestive issues, fatigue, insomnia, and even cancer. While anti-inflammatory medications may reduce symptoms, they do not address the root cause of the inflammation, which continues to persist.
Sugar – Fuelling the Fire
Many environmental factors can contribute to chronic inflammation, such as stress, poor sleep, and unhealthy diets. Sugar is a significant factor in promoting inflammation. Research shows that refined sugars – those added to foods, as opposed to the natural sugars found in fruits and vegetables – are associated with increased levels of inflammatory chemicals in the blood.
When sugar is consumed, the liver produces certain types of fatty acids, which trigger inflammatory compounds. Additionally, sugar disrupts the microbiome, encouraging the growth of bacteria that promote inflammation.
Studies have found that consuming sugary foods and drinks is linked to an increased risk of several chronic conditions, including rheumatoid arthritis, heart disease, insulin resistance, Type 2 diabetes, and inflammatory bowel disease, among others. Some studies even suggest a potential link to cancer. One study involving over 75,000 women found that those who consumed the most sugar had a 98% higher risk of developing heart disease.
The inflammatory response doesn’t just spike after you’ve eaten sugar—it can persist for several hours. If you start your day with a sweet breakfast, snack on sugary treats, and indulge after dinner, it’s easy to see how your inflammation levels could stay elevated all day long.
Sugar Everywhere
Sugar hides under many names and is present in most processed foods. These products often contain more than one type of added sugar, which can be listed as glucose, sucrose, dextrose, maltose, rice syrup, maltodextrin, or fructose, among other names.
This makes it difficult to avoid added sugar if you rely on processed foods. Even savoury products like canned vegetables, dressings, soups, and tomato sauces often contain significant amounts of sugar.
Many sugary drinks contain high-fructose corn syrup, a highly processed form of fructose strongly linked to inflammation. This makes sugary beverages particularly potent at promoting inflammation, often with no nutritional benefit.
On the other hand, the natural fructose found in fruits and vegetables doesn’t have the same effect. In plant foods, sugars are paired with beneficial nutrients like fibre, which slows the release of sugar into the bloodstream. As a result, fruits and vegetables can help reduce inflammation.
Why We Crave Sugar
If sugar is so harmful, why do we crave it? The answer lies in the brain's need for a constant energy supply. When your blood sugar levels drop, your brain signals that it wants something sweet to quickly boost those levels. However, eating sugary snacks or drinks only makes the problem worse by sending your blood sugar on a rollercoaster, which leads to even more cravings.
Managing Inflammation Naturally
By reducing your sugar intake, you can lower your levels of inflammatory chemicals, balance your blood sugar, and reduce cravings.
If you think chronic inflammation might be behind some of your health issues, I can help you explore whether your diet is contributing. Through dietary changes, supplements, and lifestyle adjustments, it’s possible to tackle the root causes of inflammation, rather than just masking the symptoms.
