Ultra-filtered milk is made using a filtration process that removes lactose while increasing other nutrients
Ultra-filtered milk is gaining popularity on shop shelves – it contains more protein, less sugar and lasts longer. But what is this product and how is it good for the body? This is what the Real simple website reports.
What is ultrafiltered milk
Ultra-filtered milk is made using a filtration process that removes lactose while increasing other nutrients such as protein and calcium.
Nutritionist Cassandra Padula Burke explained that this filtration process is done using semi-permeable membranes that allow smaller particles such as lactose and water to pass through, while retaining larger molecules such as calcium and protein. Then a little fat (depending on the percentage of milk produced) and water are often added back in to achieve the perfect texture and flavour.
Many times lactase will also be mixed into the milk at this stage to break down any remaining lactose. Also, ultrafiltered milk is (usually) pasteurised and homogenised like most other milk you’ll find in the grocery shop.
Is ultrafiltered milk healthier than regular milk?
According to nutritionist Alyssa Smolen, regular milk has about eight grams of protein per serving, while ultra-filtered milk has 13 grams. This five gram difference can be helpful for people who are trying to more easily add a little more protein to their diet. Protein supports the growth and repair of most tissues throughout the body, from muscles, hair, skin and nails.
However, for those watching their carbohydrate intake, ultra-filtered milk is also a step above regular milk. It contains almost half as much sugar as regular milk.
This is primarily due to the removal of lactose that occurs during the filtration process. Regular two per cent milk contains 12 grams of carbohydrates per cup, whereas two per cent ultra-filtered milk boasts only 6 grams. This may help people with metabolic disorders such as type 2 diabetes to better control their blood sugar levels.
Ultra-filtered also contains more calcium per serving than regular milk, which can support bone health. Regular milk contains about 300 milligrams (mg) of the mineral, while ultra-filtered milk offers 380 mg. Calcium is also an important electrolyte in the body that promotes hydration and a healthy heart rate.
Both types also contain equal amounts of micronutrients such as B vitamins, vitamin A, phosphorus, zinc and selenium, which combine to support bone, metabolic, eye and immune system health. They may also contain vitamin D, which strengthens bones and immunity.
How to use
You can use ultra-filtered milk in the same way as regular milk, such as adding it to smoothies, omelettes, cereal or homemade yoghurt.
The chocolate version makes a delicious post-workout recovery drink. Some people say the flavour of ultra-filtered milk is a little sweeter than regular milk.
It also keeps longer than regular milk, up to 45 days, compared to 17-24 days for regular milk. All thanks to the removal of more bacteria during the filtration process.
