Which milk is best?
There are plenty of debates surrounding which milk is best for you in regards to weight, health, diet etc. Most people think that skimmed is the best for you as it has the least amount of fat compared to semi-skimmed and full fat. Whilst it is lower in fat and higher in calcium compared to full fat, some research has suggested that the saturated fat in milk may not be a problem in regards to heart health. By drinking skimmed milk we may be missing out on the fat-soluble vitamins like A and E. Semi-skimmed milk is low enough in fat to be considered 'low fat', but it also has lower levels of fat-soluble vitamins compared to full fat. Ensuring that you get your fat-soluble vitamins from other sources is important.
Fat-soluble vitamin sources
- Vitamin A — carrot, sweet potatoes, broccoli, egg yolks and fortified milk
- Vitamin D — eggs, fatty fish (salmon, mackerel)
- Vitamin E — spinach, almonds, avocado, olive oil and butternut squash
- Vitamin K — dark green leafy veg
What's best for you?
Whether you choose to drink dairy or not there is plenty of other ways to ensure that you get enough calcium into your diet. Other options such as salmon, green leafy vegetables or nuts and seeds can help you need your needs. But what if you can't drink cow's milk? What if you have a lactose intolerance? What if you just don't like to drink animal products?
Cow's milk
Cow's milk is a natural product that comes from a cow. It's rich in macronutrients including protein and is a great source of calcium. Organic cow's milk contains higher levels of healthy omega-3 acids and is less likely to come from a cow that has been exposed to antibiotics and pesticides.
Lactose-free cow's milk
This is milk from a cow that has then been processed to remove the lactose, and then has the lactase enzymes added. It contains the same nutrients as regular milk. This is ideal for those that are lactose-intolerant.
Soya milk
Soya milk is similar in protein content to cow's milk but is lower in fat. Soy-based products are ideal for those that are trying to manage their cholesterol levels. This type of milk is ideal for those that are lactose intolerant and would like a lower fat option. Soya milk is naturally high in protein, vitamins, minerals and insoluble fibre.
Almond milk
This is a blend of almonds and spring water; this is then fortified with vitamins and minerals, including D and B12. This is good for those that are vegans and anyone that is avoiding animal products. It has a subtle nut taste and can come in either sweetened or unsweetened depending on your preferences.
The table below demonstrates the macro/micronutrient variability within the different forms of milk. Overall, almond milk has shown to be the lowest in calories however, it is one of the lowest options next to coconut milk for protein. When deciding which milk is the best option for you, it's best to consider all the options of milk that are available. The main finding when comparing all the available types of milk together is that the calcium content is practically the same across all of them.

Best for babies
The Department of Health promotes the idea that breastfeeding your child for the first six months of their lives is crucial and that after this stage you can continue to breastfeed with the introduction of 'solid foods'. After a child's first birthday a child can be offered full-fat milk, as a drink and semi-skimmed can be an option after the age of two – ONLY IF a child's growth is progressing, as it should. Overall, there are many pros and cons to each form of milk that you can drink. When it comes to which one you should drink there is no right or wrong. Each one has its own health benefits or is better in some ways compared to other options. It is down to you as an individual to look at all the information and the TASTE of each one to decide which one is best for you. The most important thing regardless of which one that you decide to have is that overall you are getting a well-balanced diet that is meeting not only your energy and protein requirements but also your micronutrients – vitamins, minerals!
Frequently asked questions
What is the difference between skimmed and semi-skimmed milk?
The main difference is fat content: semi-skimmed milk contains 1.8g of fat per 100ml, while skimmed milk contains just 0.1g. Both have similar calcium and protein levels, but skimmed milk is lower in fat-soluble vitamins as a result of its reduced fat content.
Which milks are lactose free?
Plant-based milks such as soya and almond milk are naturally lactose free, as are lactose-free cow's milk varieties, which have had the lactose removed and lactase enzymes added. These are ideal for those who are lactose intolerant.
Which milk is best for babies?
The Department of Health recommends breastfeeding babies between 0-6 months, and says that full-fat milk can be offered to children after their first birthday. Semi-skimmed milk is an option after their second birthday, but only if the child's growth is progressing correctly.
Is skimmed milk healthier than whole milk?
No — both have different benefits. Skimmed milk is lower in calories and fat, making it useful for those managing calorie intake. Whole milk contains more fat-soluble vitamins A and E, which are lost when fat is removed. Neither is objectively healthier; the best choice depends on your individual dietary goals.
Does almond milk have as much protein as cow's milk?
No. Almond milk contains just 0.4g of protein per 100ml, compared to 3.2-3.6g in cow's milk. It is also one of the lowest-calorie options at 13kcal per 100ml. Those relying on almond milk as a protein source should ensure they get adequate protein from other foods.
