Action Plan Against 10 Common Vitamin Deficiencies

Vitamin DeficienciesWe all have own eating habits and it’s not easy to know exactly what’s going into our bodies or the effects it will have on our health, well-being and mood. This can potentially lead to a deficiency, even with good intentions. The reasons for this are restrictions that include the tools to monitor, the time to study every food and the knowledge of your individual and ideal nutrient requirement. When these deficiencies are aggregated over a long period of time, they become more apparent and the negative impact on our health emphasised. This is why it’s important for us to know what to look out for and how to make small changes in what we eat to get the necessary nutrition that we need.

As always you should vary the foods (and colours of food) that you consume so you’re getting a balance of nutrients, and only consume in moderation. If you have any dietary requirements or medical conditions you should seek advice from your doctor/physician. If you suspect you are deficient, your doctor should give you a blood test to help identify any problems.

Please note that in this article we are focusing on deficiencies, but over-consuming vitamins can also have just as severe negative effects on the body, which is why a balance is always advised.

Here’s a list of the most common vitamin deficiencies, the signs of a deficiency, the long term effects, how to introduce the vitamins into your diet and the benefits of doing so.
