α-GPC (also referred to as Choline alphoscerate or L-alpha-glycerylphosphorylcholine) is a natural choline compound found in the brain. It is considered a parasympathetic agent and is commonly taken as a supplement for its potential cognitive and performance-enhancing effects. Cognition When ingested, it is easily absorbed and crosses the blood-brain barrier which is then metabolized into choline. Choline is a precursor to the neurotransmitter, acetylcholine, which facilitates learning, memory, and focus. Neurodegenerative Disease Most of the research in humans regarding its effect on cognition is on those with neurodegenerative diseases or some degree of cognitive decline.

Nutrition for Concussions: What Does the Research Show?

Nutrition for Concussions: What Does the Research Show?

Navigating the area of nutrition for concussions can be tricky. There's not as much direct human research as we'd like on concussions. It is, obviously, ethically challenging to study. But clearly, nutrition can help with overall brain health, including the prevention and management of concussions. The following post will be based on a combination of theoretical thinking and focusing on the evidence that we DO have. At a minimum, there will be some useful things in this post that have a high likelihood of helping. General Theme – Overall Healthy Diet As a general theme, having an overall healthy diet…

Arginine Alpha-Ketoglutarate (AAKG) – Is it Worth Taking?

Arginine Alpha-Ketoglutarate (AAKG) – Is it Worth Taking?

Arginine alpha-ketoglutarate (AAKG) is a supplement that combines the amino acid arginine with alpha-ketoglutarate (AKG). Arginine is an amino acid that plays an important role in the urea cycle and is involved in nitric oxide production, which is what it is known for in the performance space. On its own though, the absorption of arginine is quite low. AKG plays a role in metabolism by regulating energy production through the Krebs cycle, the process through which cells generate energy in the form of ATP. By combining arginine with alpha-ketoglutarate, the aim is to potentially enhance the delivery of arginine to…

Nutrition for ADHD: A Dietitian’s Guide

When it comes to ADHD, the connection between diet and symptom management is both fascinating and significant. ADHD is a broad topic though. The goal of this post is to cover most of the key things that matter. I want to acknowledge that: It would be silly to say that nutrition can “solve” or “cure” ADHD. It would be equally silly to say that nutrition plays no role in ADHD. The first section of this article will cover nutrients of interest. The reason we will start there is because there is a lot of research highlighting situations where nutrition can…

Butyrate: Everything You Need To Know

Butyrate: Everything You Need To Know

Butyrate is one of the three primary short-chain fatty acids (SCFA), alongside acetate and propionate that is produced in our gut. This tiny molecule has been shown to have far-reaching effects, from supporting gut health to lowering inflammation. Dietary Sources Butyrate actually comes from the Latin word 'butyrum', which means butter. Butter contains 3-4% butyric acid, making it the richest dietary source of butyrate. Despite this, most of this SCFA is produced by gut bacteria when dietary fibre is ingested. Therefore, to increase butyrate production you should consume a variety of fruits, vegetables, legumes, whole grains, and nuts/seeds. Aim for…

Nutrition of Rheumatoid Arthritis: What Actually Matters?

Arthritis is characterized by inflammation of the joints. Rheumatoid arthritis (RA), differs from Osteoarthritis (OA) in that it is caused by an autoimmune reaction where the immune system attacks the lining surrounding the joints. This results in inflammation, pain, swelling, and potential joint damage over time. It mainly affects the joints, but it can also affect other parts of the body. Other symptoms include red, puffy hands, fatigue, loss of appetite, fever, and hard bumps under the skin near joints. RA affects about 1% of the population and although the cause is not well understood, it seems to involve environmental,…

Why Are Carbohydrates Important for CrossFit?

Why Are Carbohydrates Important for CrossFit?

CrossFit is a branded fitness program that involves ‘constantly varied functional movements performed at high intensity.’ In a nutshell, the answer to why carbohydrates are so crucial for CrossFit comes down to human physiology and the energy systems predominantly involved in this type of training.  Carbohydrates  Carbohydrates are made up of starches, sugars and cellulose. Once digested, they are broken down into single sugar molecules in the form of glucose. This can then be stored in the muscle and liver as glycogen, ready to be used as a quick energy source.  Examples of carbohydrate-rich foods: Bread, bread rolls, wraps Pasta,…

Nutrition for Optimising Immunity in Athletes

Optimising immune function in athletes can help in numerous ways. By reducing the frequency and duration of illnesses, it allows more time for training while at peak function.
