These are organic compounds we require in tiny amounts. An organic compound is any molecule that contains carbon.
It is called a vitamin when our bodies cannot synthesize (produce) enough or any of it, so we need to get it from our food.
Vitamins are classified as water soluble (they can be dissolved in water) or fat soluble (they can be dissolved in fat). For humans, there are four fat-soluble vitamins (A, D, E, and K) and nine water-soluble vitamins (eight B vitamins and vitamin C).
Water-soluble vitamins need to be consumed more regularly because they are eliminated faster (in urine) and are not easily stored.
Fat-soluble vitamins are absorbed through the intestines with the help of fats (lipids). They are more likely to accumulate in the body because they are harder to get rid of quickly. If too many vitamins build up, it is called hypervitaminosis. A very low-fat diet can affect the absorption of fat-soluble vitamins.
We know that most vitamins have many different functions. Below is a list of vitamins, and some of their roles. Note that most often vitamin overdose symptoms are related to supplementation or impaired metabolism or excretion, not vitamin intake from foods. In Malta we may tend sometimes take vitamins for granted, but they should be taken into consideration carefully.

Most foods contain a combination of some or all of the seven nutrient classes. We require some nutrients regularly, and others less frequently.
Are you up for change? Start today, by trying to limit your intake by reducing excess or increase any deficiencies in your nutrition. It is important to always read nutritional information and ingredients of each product you consume. There may be some ingredients which are not suitable for you and could leave a negative impact on your body. Take into account other additional extras which are added, such as sauces, flavors, coloring, sweetener or sugar since often we leave them out of thought. Remember always to keep hydrated, and drink water as much as you can since in Malta our weather is usually warm, therefore more water is lost from our body. Try to avoid items such as long expiry dates since they would have additives in order for them to keep good for consumption.
There are various foods or drinks in the market which one differ from the other and have different nutrition information and ingredients. See what is best for you and what fits with you nutrition choice,
If you don’t know how, at Tminta you can find various professionals whom may guide you to make a balanced diet which includes the daily requirements for your body. There are also some tests which one could take such as food intolerance test or blood tests which may even guide you better. Always consult your doctor for guidance since it would be more personalized advice. When making changes try to change little everyday and not everything at one go, so that your body will have time to adapt to the change.
We wish you a healthy lifestyle and hope the above points help you better understanding the effects of nutrition and vitamins when consuming in food or drinks.
