Sugar and performance
Is sugar bad for you?. The short answer is no and long answer is still no. Sugar is a type of carbohydrate that is commonly found in many foods and beverages, and it has been linked to both positive and negative effects on performance. On the one hand, sugar can provide a quick burst of energy that can be beneficial for athletes and others engaging in physical activity. However, on the other hand, excessive sugar consumption can lead to negative health effects that can impair overall performance. So, in a nutshell to much may be bad in terms of performance but sugar as a whole is not and is essential to high performance individuals.

Benefits of sugar
One of the main benefits of sugar for performance is its ability to provide quick energy to the body. Sugar is a simple carbohydrate that is easily digested and absorbed by the body, and it can be used as a source of fuel for physical activity. This is why many athletes consume sugary sports drinks or energy gels during long training sessions or competitions. Sugar can also help to replenish glycogen stores in the muscles, which can help to prevent fatigue and improve endurance.
Another benefit of sugar for performance is its ability to improve mental clarity and focus. When we consume sugar, it triggers the release of dopamine in the brain, which can enhance our mood and cognitive function. This can be especially helpful for athletes who need to stay focused and alert during competition.
Limitations of sugar
It is important to note that excessive sugar consumption can have negative effects on performance. When we consume too much sugar, our bodies release insulin to regulate our blood sugar levels. This can lead to a crash in energy levels, which can impair performance and lead to feelings of fatigue and lethargy.
However, this is where in the past people have said.. GOTCHA. It’s all about the right amount at the right time. Before exercise sugar is good but before bed not so much.. that being said having milk before before is great idea for overnight protein – so, a small amount would be okay. Fundamentally we need to sugar to live not only to perform.
Sugar
If I said eat 800g of broccoli you’d probably.. yes it’s a vegetable and good for you. No, you’ll probably have stomach ache and many toilet trips. However, 100-200g would help with fibre and micronutrient intake making it an optimal choice. This is no different with sugar, if you are highly active you need sugar. If you go for a walk or run – you need sugar the amount’s just vary depending on your activities. Someone once said in a talk that we could live on sugar if we just ran everywhere – they are right. Sugar equal fuel. So don’t be scared of or drawn into the media about how bad it is.

Myths about sugar
- Sugar makes you fat = No. Calories make you fat.
- Sugar does not provide energy = No. Sugar is literally.
- Sugar causes cancer = No. So many lifestyle and dietary factors increase the risk but to say it causes shows a lack of nutritional understanding.
Take home message
In conclusion, sugar can have both positive and negative effects on performance. While it can provide a quick burst of energy and improve mental clarity and focus, we need ensure to consume the right amount pending on the exercise intention. However, there is one thing sugar is definitely bad.. your teeth! So many athletes need to look after there teeth. Ensure you regularly visit the dentist to ensure that your teeth remain healthy!
