What Happens to Your Body When You Eat Too Much Sugar

Let’s be honest, we all love a sweet treat. In the UK, women are advised to have 90g of sugar a day (not including any natural sugars that are found in fruit and veg etc…), and men 120g per day. That isn’t a huge amount, and we dramatically eat a lot more than the recommended allowance. So, what does too much sugar in your diet do to your body?

Your Brain

Your brain’s reaction to sugar, is to release a huge surge of dopamine, a chemical that gives you that “feel good” feeling that is so addictive, which will explain why you’ll want another treat, and another treat and another treat.Too much sugar in your diet impairs both your cognitive skills and your self-control.

Your Teeth

Your Mum was right, chocolate and sweets do rot your teeth. The bacteria that causes cavities love to eat sugar that is lingering in between your teeth after you’ve eaten that sweet treat!

Your skin

Sugar attaches itself to proteins in your bloodstream and creates molecules that are harmful, called “AGE’s” (advanced glycation end) which does exactly what it sounds like.Too much sugar in your diet ages your skin very fast. They attack the elastin in your skin, and damage the collagen which is what keeps you looking young and firm.

Your liver

Eating huge amounts of added sugar causes your liver to become resistant to insulin – the hormone that helps turn sugar into energy in your bloodstream. This results in your blood sugar levels fluctuating and also leads to type 2 diabetes.

 Your mood

The odd cookie can give you a quick burst of energy and raises your blood sugar fast, when your sugar levels drop, your cells absorb the sugar and that’s when you experience the sugar crash that leaves you feeling a bit dull. However, if you eat far too much sugar in your diet, your crashes can cause a lot more headaches for you. Studies show a high sugar intake is a leading cause of depression.

 Your heart

 Your weight

This won’t be news to you, but the more sugar you eat in your diet, the more you are going to weigh. Take into account the recommended guidelines, have a look at what you can swap your packet of crisps out for, and see if you can keep yourself from reaching for that biscuit tin.
