Consuming a healthy diet during pregnancy is an obvious and accepted recommedation. However, what exactly is a "healthy diet" in this context? In addition, there are specific nutrients which are crucial for the healthy development of the child, including nutrients which may be difficult to consume enough of. In addition there are nutrients and foods that need to limited or avoided during this period. In this episode, researcher and dietitian Dr. Julie Abayomi discusses important nutrients in

#440: Are Dietary Guidelines Trying To Kill Us?

Sigma Nutrition Radio ·

2022/05/31

It has become common rhetoric for those promoting various types of diets to suggest that dietary guidelines published by government departments are at best, unhealthy, or at worst, causative in driving obesity and chronic disease in the population. While different countries and organizations produce their own guidelines, with slight differences, most of the conversation has focused on the Dietary Guidelines for Americans, that are created by the USDA. Often the claims is that following these

SNP4: Detoxification Protocols [Preview]

Sigma Nutrition Radio ·

2022/05/26

There have been many claims made about the benefits of a detoxification "protocol" or "plan", based on specific dietary and supplemental regimens. Many of the arguments propose that many things we come into contact with are toxins and they can accumulate and compound in effect over time, causing a range of issues. Therefore, by removing these toxins (via a “detoxification protocol”), we can have better health. And indeed it is well known that there are a large number of toxins in the environment,

Sigma Nutrition Radio ·

2022/05/23

With elevated LDL-cholesterol being a causal risk factor for atherosclerotic heart disease, having interventions to lower blood lipids, and in particular LDL-C, are crucial for population health. A number of drugs are now incredibly effective for this, with statins being the most widely used. However, for those who do not wish to take a medication and/or have only a mild elevation, there may be potential for dietary intervention to lower LDL-C to a point where a statin (or other drug) is not needed

#438: Diet, Brain Health & Cognitive Function

Sigma Nutrition Radio ·

2022/05/17

Some cognitive decline is normal with age. However, more significant cognitive decline is primarily due to disease-induced dementias (such as Alzheimer’s Disease). It also results from neurodegenerative disorders and chronic, prolonged degeneration of our neuronal pathways and functions. Drug discovery for dementias have been largely unsuccessful, leaving no good treatments for this collection of diseases. This had led to research examining areas that may aid in preventing (or more accurately,

Sigma Nutrition Radio ·

2022/05/10

The issue of genetic enginnering in the food system is one that is often charged with emotion and strong opinion. Indeed, there has been much concern voiced over the years about the potential harms to both human health and the environment of genetically-modified (or more accurately, genetically-engineered) crops. Some concern takes the form of outright hysteria, while other concerns are more nuanced and subtle. Among these concerns, which have good evidence to support them? What regulation is

2022/05/03

Coeliac disease is an autoimmune disorder stimulated by the ingestion of gluten, a protein found naturally in wheat, barley and rye. The condition affects approximately 1% of the Western world. However, currently the only approved treatment for coeliac disease is adherence to a gluten-free diet for life. Therefore there is much research underway to develop alternative treatment options that may help these patients. One novel antigen-focused therapy that has been hypothesised is the use of plant

Sigma Nutrition Radio ·

2022/04/26

Current discussions relating to health focus on longevity. This may include some who look at lifespan extension, some who talk of delaying or “treating” ageing or those who focus on reducing morbidity within the parameters of normal lifespan. One propsed intervention that has garnered a lot of excitement, owing to some interesting research, is the potential use of fasting to increase longevity and/or healthspan. Within this broad category, various different dietary interventions have been suggested,

SNP2: "Fish is Bad For You" [PREVIEW]

Sigma Nutrition Radio ·

2022/04/19

While dietary guidelines universally include fish as a food group that can be consumed regularly in a healthy dietary pattern, there are some potential risks of fish consumption that get raised. Some have some legitimacy, for example the frequency of consumption of high-mercury fish. However, other claims can go to extremes ("eating fish is bad for you") that are based in ideology rather than evidence. In this Quack Asylum episode, we use a video made by a medical doctor as an example of where

#434: Is a Vegan Diet Really Best for Diabetes?

Sigma Nutrition Radio ·

2022/04/12

Many different diets have been put forward as solutions that treat type 2 diabetes. Some will claim the diet “reverses” diabetes, some say it puts it into “remission”, while others more conservatively recommend a diet to manage diabetes symptoms in a healthy way. There has been some debate on the use of terms like reversal, cure or resolution. And recently more clarity has been found in defining each. One of the diets that has been recommended by some for the purposes of “reversing” or treating

The relationship between our diet and sleep is bi-directional; i.e. sleep impacts diet and diet impacts sleep. Therefore, we can examine the impact of sleep timing, duration and other dimensions on our dietary intake. And then also examine the impat of both overall diet and specific nutrients on improving/worsening sleep. The is clear evidence of distinct, acute effects of restricted sleep time on food preferences, eating behaviour, energy intake, and our underlying metabolic physiology. When it

Sigma Nutrition Radio ·

2022/03/30

Omega-3 fatty acids have long been associated with various health outcomes. A type of omega-3 called alpha-linolenic acid (ALA) is found in various plant foods such as flax seeds or chia seeds. Other omega-3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are found typically in marine food sources such as oily fish (e.g. salmon, mackerel) and algae. And while higher intakes of such foods have shown benefit, there has been some confusion over the benefit of such nutrients due

There is now widespread use of various "artificial sweeteners" in foods and beverages. Most commonly non-nutritive sweeteners are used to sweeten a products, whilst having less sugar and calories than a traditionally sugar-sweetened version of that product. For example, diet drinks (e.g. diet soda) are most commonly associated with artificial sweeteners. However, they are also in a wide variety of food products and supplements.

In this Premium episode Alan and Danny aim to address the idea that you shouldn’t eat vegetables, or that they aren’t beneficial. Two related ideas have been circulated in some nutrition/health communities on the internet: Vegetables aren’t beneficial for health (or that there is no health benefit to high vegetable intake). Vegetables are actually detrimental to health, and their removal improves health. Such advice is usually defended through some combination of the following claims, which we

This has been particularly the case as a dairy alternative, with people switching to using soy ‘milk’ and soy-based yogurts and cheese. Additionally, soy has become popular as a meat alternative in a variety of dishes for those looking to reduce meat intake.

However, choices are not made in a vacuum; that is, they are not always concious decisions made for rational reasons based on free will. Rather, the choices we make about food are shaped by the contexts within which they are made. The term "food environment" is used to describe the physical, economic, political and socio-cultural contexts in which choices are made about acquiring,

And indeed evidence-based practice has been seen as the best way to arrive at coaching decisions. But is "evidence-based practice" actually what fitness professionals are doing?
