Vitamin C Does Nothing for Your Cold But it can put off Cancer

Everyone thinks that if they have the common cold or flu if they increase the dose of vitamin C in their diet (via copious amounts of orange juice, honey and lemon tea, and vitamin c supplements etc etc…). As a kid I used to take these chewy Vitamin C pills in the hope that they would help prevent me from catching the cold from school especially at every new term start but to my dismay; I still caught the cold.

So does vitamin C actually work?

Studies have stated that although vitamin C does not prevent the common cold but it actually can reduce the severity and duration of it.

The Chemistry of Vitamin C

Vitamin C is also known as ascorbic acid. Ascorbic acid is known to have anti - carcinogenic properties. In English that means that it can prevent cancer in the body. Vitamin C reacts with organic free radicals to protect from the damage caused by free radicals in cells.

When ascorbic acid comes into contact with a free radical, ascorbic acid donates a single electron to become an ascorbyl radical. The ascorbyl radical is significantly more stable than most other radical species. This results in the "quenching" of the harmful free radical (X•) to form a less reactive and less harmful ascorbyl radical. Then the ascorbyl radical donates a second electron to another harmful free radical resulting in the formation of the oxidized form of ascorbic acid: dehydroascorbic acid. 

Therefore 1 vitamin C molecule is potentially able to hunt down 2 harmful free radical species that could potentially initiate cancerous cells in the body.

So even though vitamin C may not get rid of your cold it can potentially save you from a worse condition, such as cancer.

Tips for your Masters Dissertation / Project / Thesis (PART 4)

This is the most important part of your bachelors, masters or doctorate degree so it's important you know what you're doing so you hit the ground running and don't waste valuable time being lost. When I was completing my bachelors' dissertation I was completely lost, even though I enjoyed working in the lab, I didn't enjoy the overall process and it left me really stressed and anxious. I only found out the aim of my research once I had completed and submitted my project. Granted I did get a good grade on it and it's still a piece of work I'm proud of, but if I could go back and do things differently or focus on specific parts of it, I would.
