ABC of vitamins and minerals
Have you heard the phrase “eat the rainbow”? It is a way to ensure that you get the vitamins and minerals your body needs.
Our bodies require vitamins and minerals to function optimally and the best way to get these micronutrients is from the food we eat. Have you heard the phrase “eat the rainbow”? The idea is that if we eat a variety of different coloured foods, especially fruit and vegetables, we are more likely to get a variety of vitamins and minerals from our diet than if we just ate the same food over and over again. Below is a little more information on just some of the micronutrients we need for wellbeing.
Vitamin D
Also known as the sunshine vitamin, this is the one that our bodies generate when our skin is exposed to sunlight but some can also be found in dairy foods, fatty fish and eggs. We need this vitamin to develop strong bones and it may play a role in heart health. Only a short period of sun exposure is required for our bodies to produce this vitamin, so remember to wear a suitable sun cream when you’re spending a considerable amount of time outdoors.
ACE vitamins
Vitamin A (found in liver, fish, eggs, bright vegetables like carrots and green leafy vegetables), vitamin C (found in citrus fruits, guava, tomatoes, potatoes with skin on, strawberries, kiwis, green peppers) and vitamin E (found in avocado, nuts and green leafy vegetables) are really beneficial for our health because they also act as antioxidants, providing protection against cell damage. Vitamin A is required for a healthy skin and good vision, vitamin C plays a role in a healthy immune system and the absorption of iron from other foods, while vitamin E is involved in protecting cell membranes and so helps to give us a healthy skin.
Meal idea: Make a large salad with a base of baby spinach, kale and watercress, add in sliced tomato, grated carrot, sliced avocado or green pepper and top with halved hard-boiled eggs and a sprinkling of toasted nuts and you’ll have a lovely salad with a little of each of these vitamins.
Calcium
Calcium is important for healthy bones and to help reduce the risk of fractures. A top source is dairy (cheese, milk, yoghurt, etc), but it can also be found in chia seeds, certain milk alternatives such as soy milk and nuts.
Meal idea: Soak some chia seeds in a little water until they form a gelatinous texture. Take a few scoops of plain yoghurt, top with chia seeds, a small scoop of berries or grapes and serve it for breakfast or as a small dessert.
Magnesium
Magnesium has been linked to keeping blood pressure normal and to having a positive effect on migraines, osteoporosis and PMS. It can be found in nuts, green leafy vegetables, certain legumes like beans, some cereals, chia seeds and quinoa.
Meal idea: In a large bowl, combine cooked warm quinoa, beans of your choice, a little bit of red wine vinegar and some olive oil. Mix well, scoop out onto a platter and top with green leafy vegetables to make a warm salad that can be served with grilled chicken strips.
Iron
Iron plays an important part in transporting oxygen around our bodies and is involved in healthy immune function. You can find it in a wide variety of foods such as meat, seafood, poultry, breads, cereals, fortified grain products, spinach, broccoli, beans, green beans, potatoes with the skin on, peas and dried peaches.
Meal idea: For a braai, grill some steak and serve along with a side of green beans mixed with quartered, grilled baby potatoes.
Vitamin K
This vitamin is needed for proper wound healing as it allows blood to clot. A great source of this vitamin is green leafy vegetables which can easily be added to meals and smoothies.
B group vitamins
The B vitamins, of which there are a few, can generally be found in breads, dairy products, cereals, eggs and liver, just to name a few. They mainly help our bodies to break down foods, releasing the energy from them. They are also vital for proper nerve, hormone and muscle function. Folic acid, one of the B vitamins, is especially important for pregnant women as it’s needed to generate new body and blood cells.
Meal idea: Add a tin of tomatoes to a small pan, make a small gap and crack an egg open into the gap, letting it all simmer gently until the egg has cooked. Scoop the mixture onto a slice of wholegrain bread and top with a handful of rocket.
With a well-balanced and varied diet, we are likely to get most of the vitamins and minerals we need directly from our food. Aiming for whole, unprocessed foods is always a good option because some processing may decrease the availability of micronutrients in food. Supplements, in the form of a multi-vitamin and multi-mineral, can also be considered if you feel that your diet is not up to standard or if your doctor recommends a supplement for a specific health condition.
