Do we really need vitamins and supplements?

Most people do not need to take vitamin supplements and can get all the vitamins and minerals they need by eating a healthy and balanced diet. Vitamins and minerals, such as iron, calcium, and vitamin C, are essential nutrients that your body needs in small amounts to work properly.


Many people choose to take supplements but taking too much or taking them for too long could be harmful. The Department of Health and Social Care recommends certain supplements for some groups of people who are at risk of deficiency.

Folic acid supplement in pregnancy

If you're pregnant, trying for a baby or could get pregnant, it's recommended that you take a 400 microgram folic acid supplement every day until you're 12 weeks pregnant. Folic acid supplements need to be taken before you get pregnant, so start taking them before you stop using contraception or if there's a chance you might get pregnant.

Vitamin D supplement

From around late March or early April until the end of September, most people can get all the vitamin D they need through sunlight on their skin and from eating a balanced diet. However, during the autumn and winter, you need to get vitamin D from your diet because the sun is not strong enough for your body to make vitamin D.

Vitamin D can be taken from food sources, including:
  • oily fish – such as salmon, sardines, herring and mackerel
  • red meat
  • liver
  • egg yolks
  • fortified foods – such as some fat spreads and breakfast cereals
Cows' milk is generally not a good source of vitamin D because it is not fortified.

But it's difficult for people to get enough vitamin D from food alone, everyone (including pregnant and breastfeeding women) should consider taking a daily supplement containing 10 micrograms of vitamin D during the autumn and winter. It is also recommended that:
  • breastfed babies should be given a daily supplement containing 8.5 to 10 micrograms of vitamin D from birth, even if the mother is taking a supplement containing vitamin D herself;
  • babies having 500ml or more of formula a day should not be given a vitamin D supplement, because infant formula is fortified with vitamin D and other nutrients;
  • all children aged 1 to 4 years old should be given a daily supplement containing 10 micrograms of vitamin D;
  • people who are not often exposed to the sun – such as people who are frail or housebound, are in an institution such as a care home, or usually wear clothes that cover most of their skin when outdoors should take a daily supplement containing 10 micrograms of vitamin D.
Caution: Taking too many vitamin D supplements over a long period of time can cause too much calcium to build up in the body (hypercalcaemia). This can weaken the bones and damage the kidneys and the heart. If you choose to take vitamin D supplements, 10 micrograms a day will be enough for most people.

Do not take more than 100 micrograms (4,000 IU) of vitamin D a day as it could be harmful. This applies to adults, including pregnant and breastfeeding women and the elderly, and children aged 11 to 17 years. Children aged 1 to 10 years should not have more than 50 micrograms (2,000 IU) a day. Infants under 12 months should not have more than 25 micrograms (1,000 IU) a day.

You cannot overdose on vitamin D through exposure to sunlight. But always remember to cover up or protect your skin if you're out in the sun for long periods to reduce the risk of skin damage and skin cancer.

For the other vitamins, you should be able to get all the vitamin K you need by eating a varied and balanced diet.

What is a varied and balanced diet?

The Eatwell Guide shows that to have a healthy, balanced diet, people should try to:
  • eat at least 5 portions of a variety of fruit and vegetables every day;
  • base meals on higher fibre starchy foods like potatoes, bread, rice or pasta
  • have some dairy or dairy alternatives (such as soya drinks)
  • eat some beans, pulses, fish, eggs, meat and other protein
  • choose unsaturated oils and spreads, and eat them in small amounts
  • drink plenty of fluids (at least 6 to 8 glasses a day)
The Eatwell Guide does not apply to children under the age of 2 because they have different nutritional needs. Between the ages of 2 and 5 years, children should gradually move to eating the same foods as the rest of the family in the proportions shown in the Eatwell Guide.

Five portions of a variety of fruit and vegetables:

It can be fresh, frozen, canned, dried or juiced. Examples of a portion are:
  • 80g of fresh, canned or frozen fruit and vegetables;
  • 30g of dried fruit – which should be kept to mealtimes;
  • 150ml glass of fruit juice or smoothie;
  • 01 apple, banana, pear or similar-sized fruit;
  • 01 slice of pineapple or melon;
  • 03 heaped tablespoons of vegetables is another portion.
Adding a tablespoon of dried fruit, such as raisins, to your morning cereal is an easy way to get 1 portion. You could also swap your mid-morning biscuit for a banana, and add a side salad to your lunch. In the evening, have a portion of vegetables with dinner and fresh fruit with plain, lower fat yoghurt for dessert to reach your 5 A Day.

Starchy foods in your diet

Starchy foods should make up just over a third of everything you eat. Choose wholegrain or wholemeal varieties of starchy foods, such as brown rice, wholewheat pasta, and brown, wholemeal or higher fibre white bread. They contain more fibre, and usually more vitamins and minerals, than white varieties.

Potatoes with the skins on are a great source of fibre and vitamins. For example, when having boiled potatoes or a jacket potato, eat the skin too.

Milk and dairy foods (and alternatives)

Milk and dairy foods, such as cheese and yoghurt, are good sources of protein. They also contain calcium, which helps keep your bones healthy. 

Go for lower fat and lower sugar products where possible. Choose semi-skimmed, 1% fat or skimmed milk, as well as lower fat hard cheeses or cottage cheese, and lower fat, lower sugar yoghurt. Dairy alternatives, such as soya drinks, are also included in this food group. When buying alternatives, choose unsweetened, calcium-fortified versions.

Beans, pulses, fish, eggs, meat and other proteins

Meat is a good source of protein, vitamins and minerals, including iron, zinc and B vitamins. It's also one of the main sources of vitamin B12. Choose lean cuts of meat and skinless poultry whenever possible to cut down on fat. Always cook meat thoroughly. Try to eat less red and processed meat like bacon, ham and sausages.

Eggs and fish are also good sources of protein, and contain many vitamins and minerals. Oily fish is particularly rich in omega-3 fatty acids. Aim to eat at least 2 portions of fish a week, including 1 portion of oily fish (such as salmon, trout, herring, sardines, pilchards, mackerel). You can choose from fresh, frozen or canned, but remember that canned and smoked fish can often be high in salt

Pulses, including beans, peas and lentils, are naturally very low in fat and high in fibre, protein, vitamins and minerals. Nuts are high in fibre, and unsalted nuts make a good snack. But they do still contain high levels of fat, so eat them in moderation.

Fat

Too much saturated fat can increase the amount of cholesterol in the blood, which increases your risk of developing heart disease. Saturated fat is found in many foods, such as: fatty cuts of  meat, sausages, butter, hard cheese, cream, cakes, biscuits, lard, pies. Try to eat less saturated fat and choose foods that contain unsaturated fats instead, such as vegetable oils and spreads, oily fish and avocados.

For a healthier choice, use a small amount of vegetable or olive oil, or reduced-fat spread instead of butter, lard or ghee. When you're having meat, choose lean cuts and cut off any visible fat. All types of fat are high in energy, so they should only be eaten in small amounts.


Eat less salt: no more than 6g a day for adults

Even if you do not add salt to your food, you may still be eating too much. About three-quarters of the salt you eat is already in the food when you buy it, such as breakfast cereals, soups, breads and sauces.

Use food labels to help you cut down. More than 1.5g of salt per 100g means the food is high in salt.

Adults and children aged 11 and over should eat no more than 6g of salt (about a teaspoonful) a day. Younger children should have even less.

Do not get thirsty

You need to drink plenty of fluids to stop you getting dehydrated. It is recommended to drink 6 to 8 glasses every day. This is in addition to the fluid you get from the food you eat.

All non-alcoholic drinks count, but water, lower fat milk and lower sugar drinks, including tea and coffee, are healthier choices. Unsweetened fruit juice and smoothies are high in free sugar, so you should limit them. Your combined total of drinks from fruit juice, vegetable juice and smoothies should not be more than 150ml a day, which is a small glass. 

Remember to drink more fluids during hot weather or while exercising.


Do not skip breakfast

Some people skip breakfast because they think it'll help them lose weight. But a healthy breakfast high in fibre and low in fat, sugar and salt can form part of a balanced diet, and can help you get the nutrients you need for good health.

A wholegrain lower sugar cereal with semi-skimmed milk and fruit sliced over the top is a tasty and healthier breakfast.


Physical activities

Adults should aim to: 
  • do strengthening activities that work all the major muscle groups (legs, hips, back, abdomen, chest, shoulders and arms) on at least 2 days a week
  • do at least 150 minutes of moderate intensity activity a week or 75 minutes of vigorous intensity activity a week
  • spread exercise evenly over 4 to 5 days a week, or every day
  • reduce time spent sitting or lying down and break up long periods of not moving with some activity
Moderate activity will raise your heart rate, and make you breathe faster and feel warmer. Examples of moderate intensity activities include: brisk walking, water aerobics, riding a bike, dancing, doubles tennis, pushing a lawn mower, hiking, rollerblading

Vigorous intensity activity makes you breathe hard and fast. Examples of vigorous activities include: running, swimming, riding a bike fast or on hills, walking up the stairs, sports, like football, rugby, netball and hockey, skipping, aerobics, gymnastics, martial arts.

Very vigorous activities are exercises performed in short bursts of maximum effort broken up with rest. Examples of very vigorous activities include: lifting heavy weights, circuit training, sprinting up hills interval running, running up stairs, spinning classes.

Activities that help you strengthen your muscles are carrying heavy shopping bags, yoga, pilates, tai chi, lifting weights, working with resistance bands, doing exercises that use your own body weight, such as push-ups and sit-ups,heavy gardening, such as digging and shovelling, wheeling a wheelchair lifting and carrying children.
