Exercise, gut health and gastrointestinal issues
Exercise is generally regarded as beneficial for health. Gut health is not an exception, athletes tend to have microbiomes with increased composition and/or function. However, too much exercise can be detrimental. This is an overview on exercise, gut health and gastrointestinal issues. Exercise and gut health Most people will agree that exercising is beneficial for health. When comparing the microbiomes of exercising individuals (including athletes) with those of sedentary individuals, scientists have found: More bacterial diversity and/or richness, generally regarded as beneficial to health More short-chain fatty acid (SCFA) metabolic pathways, important for intestinal integrity and other aspects of health Increased metabolic pathways of amino acids (including branched-chain amino acid,…

How to add more protein to your breakfast

Moreover, sports nutrition science points at an ideal dose of 0.25-0.30g of protein per kg of body weight per meal (including breakfast!) for building muscle. High protein breakfasts Breakfasts that can be naturally high in protein include: Leftovers from dinner Egg-based breakfasts (boiled/poached/fried/scrambled eggs, omelette, frittata) Smoothie with milk, yoghurt and/or protein powder However, if your breakfast…

Barista milk
Barista milk is formulated to produce beautiful and tasty milk-based coffees, especially when using plant-based (e.g. almond, oat, soy) milks. Why barista milk? A milk-based coffee with stunning latte art requires milk that won’t break when heated and that will produce the right size of bubbles for texture. For the most part, this is not an issue with cow’s milk. However, non-dairy (i.e. plant-based) milks can be tricky to work with. In addition, coffees bought at cafes need to taste better than anything you can make at home. Barista milk in the Australian market Many manufacturers of dairy and non-dairy milks now offer a barista range of products. Brands include…

Should you eat breakfast?
Should you eat breakfast? This continues to be a controversial topic when it comes to health and nutrition. Although every person’s biology is different, it seems that the majority of people would benefit from not skipping the first meal of the day. Breakfast: the most important meal of the day? Conspiracy theorists and skeptics tend to be of the opinion that breakfast was proclaimed “the most important meal of the day” as a marketing strategy to increase the food industry’s profits. However, there has been some scientific evidence to suggest that breakfast is indeed associated with weight loss and improved body composition (1). Benefits of eating breakfast Satiety and hunger…

Protein requirements for female athletes
Are protein requirements for female athletes the same than those of male athletes? Although it makes sense to think that body composition, energy metabolism and sex hormones may play a role in nutrient requirements, there are no fast and hard rules, but sensible guidelines as detailed below. Protein requirements for female athletes In theory, female athletes should have slightly lower protein requirements than their male counterparts because oestrogen causes exercising female bodies to increase fatty acid oxidation and decrease amino acid (and carbohydrate) oxidation (1, 2). Moreover, protein catabolism is higher in the luteal phase when oestrogen and progesterone are high (1). On the other hand, some studies seem to…

Muscle cramps during exercise
Muscle cramps during exercise are relatively common and have been investigated for decades but remain a mystery. Scientists have identified potential risk factors, causes and solutions but evidence is not very solid. Exercise-associated muscle cramps Also known as EAMC, these are cramps that happen during or immediately after exercise (1, 2). Muscle cramps occur in a wide range of athletes participating in a variety of disciplines. These are most commonly reported in endurance-type sports and team sports (1) although this could be due to research bias. EMAC are usually a minor inconvenience but they can vary in intensity and duration, with a very small percentage of the population experiencing severe…
