Full fat, low fat, skim, lactose-free, soy, rice, almond, oat -- with such an array of dairy and non-dairy milk products available, shopping for the right milk can be a confusing and difficult task.

Whether you like your plain dairy milk (but are unsure if low fat or full fat is best) or you want to try non-dairy milk (but don’t know where to start), this guide is for you.

“Dairy is an important food group that provides us with protein, calcium, vitamin and minerals,” accredited practising dietician Sanchia Parker told The Huffington Post Australia.

In particular, dairy milk contains vitamin A and B12, riboflavin, phosphorus, potassium, magnesium and zinc.

“Calcium is important for building and maintaining healthy bones and teeth,” Parker said. “A dairy product or dairy alternative is a good source of calcium if it contains 100mg of calcium or more per 100ml.”

“A serve of milk is 250ml, or one cup,” Parker said. “Ideally, we need between two-and-a-half to four serves of dairy a day, depending on age, gender and physical activity.”

Full cream

“Full cream milk has the highest percentage of fat in it -- around 3.8 percent on average,” Parker said. “This has the creamiest taste due to the higher fat content.”

If making good coffee is high on your priority list, full cream milk is most baristas' milk of choice for its ability to produce and hold silky frothiness.

Low fat

“This milk has slightly less fat in it -- around 1.3 percent to 1.4 percent,” Parker said. “This milk often has skim milk powder added to it, which improves the taste to make it creamier and also boosts the protein and calcium content.”

“Low fat is better in terms of reducing how much saturated fat you’re having, so that’s really important when it comes to keeping cholesterol levels low and improving our heart health,” Parker said.

Low fat milk is also a good option for those watching their weight.

“You’re also shaving off a few extra kilojoules out of your diet so, for someone who is looking to lose weight, the low fat milk is a better option,” Parker said.

Skim milk

“This milk has the lowest amount of fat in it, with no more than 0.15 percent milk fat,” Parker said. “Typically, milk solids or milk powder are added to improve the taste of the milk.”

Many people may not enjoy the watery taste of skim milk, but it does have nutritional advantages.

“Nutritionally, the added solids or powder provides extra protein and calcium,” Parker said.

Skim and low fat milk do have a higher sugar content, but Parker says this is natural occurring sugar in dairy.

“Some people are concerned that low fat products have added sugar in and that can appear to be the case -- when you’ve taken the fat out it looks like there’s more sugar left, but it’s just that naturally occurring sugar: the lactose.”

Lactose-free milk

“This milk is suitable for people who are lactose intolerant,” Parker said. “The lactose in this milk has been removed, making it more easily digested for those with lactose intolerance.”

Avoiding dairy?

“The most important thing you need to ensure is that your new milk alternative is fortified with calcium,” Parker told HuffPost Australia. “Take a look at the nutritional panel and in the table where it says calcium, make sure there is at least 100mg for every 100ml of liquid.”

As the calcium is added in the form of calcium carbonate powder, Parker has one tip to ensure you're getting the most from the calcium.

“With the dairy-free milks the added calcium sinks to the bottom of the milk, so before you have it, shake the bottle up to make sure you’re getting the calcium in there,” Parker said.

Parker also advises to be wary of the sugar content.

“Be careful of dairy-free milks that have added sweeteners -- plenty of brands include sugar, honey and other sweeteners to improve the taste of the products. If this is a concern, opt for unsweetened varieties,” Parker said.

Rice and oat milk

Rice and oat milk are naturally sweet and are more palatable non-dairy milk options, but are not the best options in terms of nutrition, according to Parker.

“Probably the most questionable ones for me are the rice and oat milk,” Parker said. “There’s so much added sugar to it and they are so low in protein -- it’s essentially just sugary water with very little actual rice or oats.”

“Rice milk is good for people who have a lot of allergies because it’s the most hypoallergenic but, more generally, if you’re going to try dairy-free milk I would stick to the soy milk.”

Soy milk

“Soy milk is a good dairy-free option,” Parker said. “It’s got a bit more of the good fats and has a higher protein content, so it’s going to help you to feel full which is what you want.”

Parker recommends looking for one with a high calcium content and, if you are concerned about sugar, opt for the unsweetened ones.

Almond milk

Almond milk is one of the most popular dairy-free milks. According to Parker, however, while it is high in vitamin E and low in fat, it's lower in protein than milk and, again, can be high in sugar.

Those who are environmentally conscious may also like to choose a different non-dairy milk. As Sarah Wilson discussed, it takes five litres to grow one almond and come with a large carbon footprint as almonds are usually imported to Australia.

The process of making almond milk also produces a lot of food waste, as the leftover pulp extracted from the almonds is often tossed away.

Flavoured milk

Although delicious, flavoured milk is not the recommended milk choice -- however, it’s better than some sugary drink options.

“Obviously I wouldn’t recommend going out and having chocolate milk, but if you are going to have a sweet drink, flavoured milk is probably going to be better than soft drink because at least it’s got some protein and vitamin A and B12,” Parker said.

The best milks

“As a general guide, opt for skim milk as this contains the least amount of saturated fat and also contains higher levels of calcium and protein, which is an extra nutritional bonus,” Parker said. “Try Pauls Physical No Fat with a whopping 174mg of calcium and 4.1 grams of protein per 100ml.”

For non-dairy milks, Parker's choice is soy milk due to it higher protein content.

“Try Vitasoy Calci-Plus which has 160mg calcium and 3.2 grams of protein per 100ml,” Parker said.
