Milk as a sports supplement
Milk as a sports supplement? Why not! Milk is a relatively inexpensive source of many nutrients, which include protein, calcium, vitamins and minerals. Milks from different ruminants (e.g. cows, goats, water buffalo) have similar nutrient profiles. However, for the sake of this article we will be talking about cow’s milk as it’s the most available and commonly consumed. Nutrients in milk Milk and other dairy foods contain calcium, protein, B vitamins (including B2 and B12), vitamins A and D, phosphorus, potassium, magnesium, zinc and iodine. The table below shows average content for some nutrients of different types of plain cow’s milk (data from 1). A glass of milk has 8…

The Health Star Rating System
The Health Star Rating System is a way of labelling food products in Australia to indicate their healthiness. Similar to energy ratings, health ratings are meant to guide consumers toward better choices. What is the Health Star Rating System?

It is being used voluntarily by manufacturers since June 2014 and reviewed every 5 years. Assigned ratings go from ½ star (least healthy) to 5 stars (most healthy), which are displayed on food product packaging. How is the Health Star Rating calculated?

Sugar-containing ingredients
Now that you know that there is little difference between brown sugar vs white sugar, that added sugar consumption in Australia is higher than it should be and how to read food labels, it is time to put it all together by looking at sugar-containing ingredients. What is sugar? The term sugar “refers to all carbohydrates of the general formula Cn(H2O)n” (1). Single sugars such as glucose and fructose are known as monosaccharides. Two monosaccharides linked together (e.g. sucrose = glucose + fructose, lactose = glucose + galactose) are known as disaccharides. Many sugars linked together are known as polysaccharides. Added and free sugars As a reminder, added sugars are…

They typically contain several ingredients in various quantities which are sometimes undisclosed and marked as “proprietary blends” (1, 2, 3). Common ingredients Common ingredients in pre-workout supplements include caffeine, creatine and beta-alanine (2, 3), branched-chain amino acids (BCAAs), nitrates (2), citrulline, taurine, tyrosine and B vitamins (3).

Added sugar consumption in Australia
Intake of added sugars has been associated with health issues such as weight gain and dental caries. As it happens with most developed countries, added sugar consumption in Australia exceeds recommended limits. Last week I explained the difference between added, free and total sugars. Briefly, added sugars are those that do not occur naturally in foods and are added before consumption. Free sugars include added sugars and the natural sugars in honey, syrups and fruit juices (1). Regarding recommended intake of added and free sugars, guidelines differ. The Australian Dietary Guidelines recommend limiting the intake of added sugars but do not specify a quantity (2). The World Health Organisation (WHO)…

Should you take BCAAs?
Branched-chain amino acids (BCAAs) is the name given to three of the nine essential amino acids. BCAAs are sold as a sports supplement to increase muscle synthesis and recovery. Today we answer the question: Should you take BCAAs? What are BCAAs? BCAAs or branched-chain amino acids are leucine, isoleucine and valine. They are essential amino acids (EAAs), meaning they cannot be made by our bodies and must be taken from the diet. Unlike other amino acids, BCAAs are not metabolised in the liver (1, 2) but in skeletal muscle (2). They can be oxidised and used as energy (2, 3). BCAA supplements are commonly used in athletic populations. Most supplements…
