The Hidden Dangers of Sugar: Why It’s More Than Just a Sweet Treat

You start your morning with a seemingly healthy breakfast—maybe a bowl of quick-cook porridge with banana and honey, a smoothie, or even some granola with yogurt. At lunch, a shop-bought sandwich. An afternoon pick-me-up? A “healthy” cereal bar, protein bar or a low-fat yogurt. Dinner is a comforting bowl of pasta and maybe a glass of wine. It all seems fairly balanced, right?

But when you zoom in, it's a sugar storm.

Why Sugar is So Harmful

Sugar is more than just an empty calorie. When consumed in excess, it wreaks havoc on the body. It disrupts blood sugar control, triggers chronic inflammation, and fuels cravings that make it almost impossible to stop eating. Over time, this can lead to insulin resistance, increased fat storage, gut imbalances, and a heightened risk of serious conditions like heart disease, type 2 diabetes, and even certain cancers.

Sugar is also a major contributor to cardiovascular disease. Excess sugar increases insulin levels, which can lead to high blood pressure, increased triglycerides, and arterial damage—key risk factors for heart attacks and strokes.

Additionally, sugar has a profound effect on brain health. Chronic high sugar intake has been linked to an increased risk of dementia due to its role in insulin resistance in the brain, sometimes referred to as type 3 diabetes. Many women also find that sugar worsens brain fog, mood swings, and energy crashes, particularly during perimenopause when the body becomes naturally more insulin-resistant. This is why excess sugar can lead to stubborn weight gain, particularly around the abdomen, and worsen menopause symptoms like hot flashes and fatigue.

The Addictive Power of Sugar

If sugar was just another nutrient, we’d eat it in moderation and move on. But sugar is addictive.

Food manufacturers know exactly how to create products that hijack your brain’s reward system, combining sugar, fat, and salt in the perfect "bliss point" to make you crave more. That cereal bar or chocolate biscuit isn’t just a snack—it’s been designed to make you want another. And another.

Sugar disrupts two key hunger hormones:

• Ghrelin: Tells you when you’re hungry.

• Leptin: Signals when you’re full.

Excess sugar consumption blunts leptin sensitivity, so you don’t feel satisfied after eating—leading to overeating and more cravings.

The Sneaky Ways Sugar Creeps into Your Diet

Most people underestimate how much sugar they consume. It’s not just about cakes and biscuits—it’s hidden in everyday foods. From yogurts to pasta sauces, sugar finds its way into nearly everything. One of the biggest offenders? Syrups.

Many products marketed as "natural" use syrup-based sweeteners, which are still just sugar in disguise. Whether it’s maple syrup, agave nectar, rice syrup, or fruit juice concentrate, they all have the same effect on your body. Some of these, like agave nectar, are even worse than table sugar due to their high fructose content, which overburdens the liver and contributes to fat storage.

Reading ingredient lists carefully is crucial. Sugar often hides under dozens of different names, making it difficult to spot. In fact, many processed foods list multiple sugars within the first few ingredients. These include:

• Sucrose, fructose, glucose, dextrose, maltose

• High-fructose corn syrup, cane sugar, coconut sugar, fruit juice concentrate

• Barley malt, rice syrup, molasses, honey, agave nectar

If a product lists more than one type of sugar near the top of the ingredient list, chances are it’s not as healthy as it seems. Many breakfast cereals, granola bars, flavoured yogurts, and even so-called "healthy" drinks contain multiple added sugars disguised under different names.

How Sugar Impacts Gut Health and Hormones

You may not notice sugar’s effects immediately, but over time, it can seriously harm your gut. Excess sugar feeds harmful bacteria and yeast, leading to imbalances in your microbiome. This can cause bloating, IBS symptoms, and even contribute to leaky gut, where the gut lining becomes more permeable, allowing toxins and undigested food particles to enter the bloodstream.

For women, sugar can be particularly problematic in perimenopause. It contributes to blood sugar swings that amplify mood swings, hot flashes, and energy crashes. If you’ve been feeling irritable, exhausted, or prone to cravings, excess sugar could be a key player.

Sugar and Fat Storage—Even If You’re Not Overeating

A diet high in sugar makes you store more fat, even if you don’t think you’re overeating. Here’s why:

• When glucose levels are consistently high, insulin remains elevated, signalling the body to store energy instead of burning it.

• Fructose (found in many "natural" sweeteners like agave and fruit juice concentrates) is processed in the liver, where it can be converted into fat.

• High sugar consumption disrupts metabolism, leading to stubborn weight gain, particularly around the midsection.

Reducing Sugar for Better Energy, Mood, and Health

The good news? Cutting back on sugar has almost immediate benefits. Many of my clients notice increased energy, better sleep, and improved mood within just a few weeks. Their cravings subside, their digestion improves, and they feel more in control of their eating habits.

If you’re looking for ways to reduce sugar without feeling deprived, try these swaps:

• Breakfast: Swap sugary cereals for eggs on wholemeal toast, Greek yogurt with nuts & berries, or chia pudding.

• Snacks: Choose nuts and seeds, hummus with veggies, or oatcakes with cottage cheese instead of processed snack bars.

• Drinks: Avoid fruit juices, smoothies, and sweetened coffees. Stick to water, herbal teas, or unsweetened drinks.
