Milk and dairy products are good sources of both protein and calcium, and form part of a healthy diet. Choose lower-fat dairy foods where possible, because these are healthier choices.

The total fat content of dairy products can vary a lot. Fat in milk provides calories for young children and also contains essential vitamins such as vitamins A and D.

However, much of the fat in milk and dairy foods is saturated fat. For older children and adults, eating too much saturated fat can contribute towards becoming overweight. It can also cause raised levels of cholesterol in the blood, and this can put you at increased risk of a heart attack and stroke.

You can check the amount of fat, salt and sugar in most dairy foods by looking at the nutrition information on the label. If you compare similar products you will be able to make healthier choices. Learn more in Food labels.

For more information on different fats, see Fat: the facts.

Milk

If you’re trying to cut down on fat, it’s a good idea to go for lower-fat milks.

Semi-skimmed, 1% fat and skimmed milks contain all the important nutritional benefits of milk, but are lower in fat.

Cheese

Cheese can form part of a healthy diet, but it’s a good idea to keep track of how much you eat and how often.

Most cheeses – including brie, stilton, cheddar, lancashire and double gloucester – contain between 20g and 40g of fat per 100g. Foods that contain more than 20g of fat per 100g are high in fat.

Some cheeses can also be high in salt. Eating too much salt can contribute towards high blood pressure.

If you’re using cheese to flavour a dish or a sauce, you could try using a more strongly flavoured cheese, such as mature cheddar or blue cheese, because then you’ll need less.

Another option is to choose reduced-fat hard cheeses, which usually contain between 10g and 16g fat per 100g. A few cheeses are even lower in fat (3g fat per 100g or less), including reduced-fat cottage cheese and quark.

Other dairy foods

Butter is high in fat, so try to use it sparingly. Low-fat spreads can be used instead of butter.

Cream is also high in fat, so use this sparingly too.You can use plain yoghurt and fromage frais instead of cream, soured cream or crème fraîche in recipes.

When eating yoghurts or fromage frais, you can choose low-fat varieties. These products contain at least the same amount of protein, calcium and some other vitamins and minerals – such as B vitamins and magnesium – as full-fat versions. They just contain less fat.

Dairy foods are important in pregnancy, because calcium helps your unborn baby’s developing bones to form properly.

But when pregnant, there are some cheeses and other dairy products that you should avoid, as they may make you ill or harm your baby.

Pregnant women should drink only pasteurised milk.
Most cow’s milk found in shops is pasteurised: check the label if you are unsure. If only unpasteurised milk is available, boil it first.

Pregnant women should not drink unpasteurised goat’s or sheep’s milk, or eat foods that are made with them, such as soft goat’s cheese. See below for more on pasteurisation.

Pregnant women should avoid soft blue cheeses, and soft cheeses such as brie and camembert and others with a similar rind, whether pasteurised or unpasteurised. This is because they can contain high levels of Listeria, a bacteria that can cause miscarriage, stillbirth or severe illness in a newborn baby.

There is no Listeria risk with cottage cheese, processed cheese or hard cheeses such as cheddar or parmesan, even if they are unpasteurised, so there is no need to avoid these. Learn more in the Pregnancy care planner.

Babies and children under five

Milk and dairy products are an important part of a child’s diet.

They are a good source of energy and protein, and contain a wide range of vitamins and minerals. They are rich in calcium, which growing children and young people need to build healthy bones and teeth.

For around the first six months of your baby’s life, the Department of Health recommends exclusive breastfeeding (with no other food or drink). Find out more in Feeding your baby.

If you are not breastfeeding, you can use formula milk instead. Find out more in Different types of infant formula.

Cow’s milk should not be given as a drink until a baby is a year old. This is because it doesn’t contain the right balance of nutrients to meet your baby’s needs.

Full-fat cow’s milk can be used in small amounts for cooking in foods such as cheese sauce and custard from six months.

Babies under one year old should not be given condensed milk, evaporated milk, dried milk, or any other type of drinks often known as milks, such as rice, oat or almond drinks.

Children should drink full-fat milk until they are at least two years old, because they may not get the calories or essential vitamins they need from lower-fat milks.

After the age of two, children can gradually move to semi-skimmed milk as a main drink, as long as they are eating a varied and balanced diet and growing well.

Don’t give skimmed or 1% fat milk to children as a main drink until they’re at least five years old, because neither of these contains enough vitamin A and skimmed milk doesn’t contain enough calories.

Children between the ages of one and three need to have around 350mg of calcium a day. About 300ml milk (just over half a pint) would provide this.

Goat’s and sheep’s milk

Like cow’s milk, goat’s and sheep’s milk aren’t suitable as drinks for babies under a year old, because they don’t contain the right balance of nutrients.

Providing they are pasteurised, ordinary full-fat goat’s and sheep’s milk can be used as drinks once a baby is a year old. They can be used for cooking in foods such as cheese sauce and custard from the age of six months.

Pasteurisation is a process of heat treatment intended to kill bacteria and prevent food poisoning.

Most milk and cream is pasteurised. If milk is unpasteurised, it is often called “raw milk”. This must carry a warning saying that it has not been pasteurised, and may contain harmful bacteria.

You can sometimes buy unpasteurised milk and cream. However, these could be harmful, because they may contain bacteria that can cause food poisoning.

If you choose unpasteurised milk or cream, make sure they are kept properly refrigerated because they have a short shelf-life.

Some other dairy products are made with unpasteurised milk. These include some cheeses, such as stilton and camembert, brie and goat’s cheese.

Children, people who are unwell, pregnant women and older people are particularly vulnerable to food poisoning and so should not have unpasteurised milk or cream, or dairy products made with unpasteurised milk.

There are three conditions involving reactions to milk.

Milk and dairy foods are good sources of important nutrients, so don’t cut them out of your (or your child’s) diet without first speaking to a GP or dietitian.

Lactose intolerance

Some people cannot digest the special type of sugar found in milk, called lactose. This is also called “lactose intolerance”.

Lactose intolerance can cause symptoms such as bloating and diarrhoea. It does not cause severe reactions.

Learn more in Lactose intolerance.

Milk allergy

Milk allergy can cause severe reactions, but usually the symptoms are mild.

They can affect any part of the body and can include rashes, diarrhoea, vomiting, stomach cramps and difficulty in breathing.

In some cases milk allergy can cause anaphylaxis. This is a life-threatening allergic reaction, which involves difficulty in breathing, swollen lips or mouth, and collapse. If this happens, call 999 immediately and describe to the operator what is happening.

Learn more in Food allergy.

Cow’s milk protein intolerance

Cow’s milk protein intolerance (also known as milk intolerance) is different from milk allergy and lactose intolerance. It can occur in adults and children, but is more common in babies and children.

Children with this intolerance can experience symptoms the first time they drink cow’s milk. The symptoms include eczema, vomiting, diarrhoea and stomach cramps.

They do not include hives, or breathing problems: these are symptoms of milk allergy.

Children who have cow’s milk protein intolerance often grow out of it by the time they go to school, but on rare occasions it can persist into adulthood.

As with all food allergies and intolerances, if you think you or your baby has a milk intolerance, make an appointment to talk to your GP or other health professional.
