Walking around a city like London, you can’t really go more than 5 minutes without stumbling across a food or drink outlet. The improvement in food production and distribution has massively helped overcome food insecurity. When was the last time you were worried about your local shop running out of bread?
But with the increase in food availability means we eat more because let’s be honest, we are all culprits of over eating or eating just because we are bored. The over consumption of food has led to an increase in diseases such as cardiovascular disease, diabetes and cancer which are the leading causes of death in high income countries with global obesity rates having tripled in the last 40 years. And if we take a look at the diet of Western countries like the UK, it mainly consists of animal fats, refined grains and sugar whilst severely lacking in a variety of fruit and vegetables.
Unfortunately, going down the aisle in the supermarket, it’s hard to find a manufactured food or drink product that doesn’t contain sugar of some form. Sugar is an additive that makes food more palatable for the consumer and you’ll find sugar even in foods you wouldn’t expect to. Some prime examples are...
If you look at the back of a pack the most common names for sugar include cane sugar, corn syrup, glucose, caramel, maltodextrin and fruit juice concentrates just to name a few. The British Heart foundation has come up with a usefulinfographic that lists 50 different names sugar has on ingredients labels, so don’t be fooled!
How does sugar impact the immune system?
To fight off infection, your body relies on white blood cells as they are basically the guys that are in charge of killing viruses so you want them around. These white blood cells are also known as killer cells. But eating too much sugar inhibits your white blood cells ability to do what they do best and keep you sickness free for another day. And we always harp on about getting more than 6 hours of sleep or else these amazing natural killer cells drop by a staggering 70%. But even if you’re getting a full 8 hours of beautiful sleep, eating too much sugar will just cancel that out.
A high sugar diet can especially affect people who are diabetitic. Whilst a high sugar diet can lead to type 2 diabetes, it also significantly reduces its response to an infection, more so that non diabetic individuals which was demonstrated in astudy. This is unfortunately why having diabetes is associated with having worse symptoms and serious complications of C**** (by now you probably know we can’t say the C-word for censorship reasons). But because our bodies are so powerful, with radical lifestyle changes, type 2 diabetes can be reversed!
Astudy showed that it only takes 75g of sugar to weaken your immune system. Let's put that into perspective. Picture this, you have a glass of orange juice for breakfast with a granola bowl topped with some low fat strawberry yogurt. The orange juice has around 30 g of sugar, the granola has around 10g per serving and the low fat yogurt has around 25g of sugar. In just one meal, you’ve eaten 87% of the 75g of sugar. And with the list of unexpected sugary foods mentioned before it’s not that hard to go over 75g.
The World Health Organisation says that you should get no more than 10% of your calories from added sugar a day, which is around 6 teaspoons or 30g. Don’t get me wrong, I know it’s hard especially when you have a sweet tooth, but replacing sugar with healthier alternatives such as honey, agave, dates and stevia is a great step in taking care of your body so it can utilise its incredible power. Because the goal is to live a life in full colour, right?
