The Mediterranean diet: the health benefits keep growing

Considered one of the world’s healthiest dietary patterns, the Mediterranean diet is linked to a host of positive health benefits. The theme of the diet is one abundant in fruits, vegetables, wholegrains, legumes and olive oil and where fish and poultry feature more often than red meat. From less chronic disease right through to a longer life, in this podcast I’ll dig deeper into the health merits of adopting some of the key themes of the Mediterranean diet for your own individual way of eating.

Vitamin B12: foods, functions and deficiencies

Vitamin B12 is an essential nutrient integral to the healthy functioning of the brain and nervous system. It is also involved in DNA synthesis and the formation of red blood cells. Because vitamin B12 is produced by bacteria in the large intestines of animals, plant-based foods are not a reliable source of vitamin B12 making people who follow a vegan diet a key at-risk group for deficiency. In this podcast, I’ll look at the roles of vitamin B12 and the main causes and consequences of deficiency.

Low-carb diets: are they the best way to manage diabetes?

Low-carbohydrate diets are certainly on trend today. And it is for diabetes that such diets have attracted a lot of attention. Low-carbohydrate diets have without question helped many people with diabetes keep their blood sugar levels more stable and even for some people with type 2 diabetes helped to even help to fully resolve their diabetes. In today’s podcast, I look at the history of dietary recommendations for diabetes. I’ll then look at what the scientific evidence says for how effective low-carbohydrate diets are for diabetes compared to other approaches.

Iodine: why you need it and where you find it

Iodine is a trace element that is naturally present in foods and is added to some types of salt. Iodine is an essential component of thyroid hormone which plays a key role in digestion, heart and muscle function, brain development and maintenance of bones. Getting enough iodine is important for everyone, especially infants and women who are pregnant. In this podcast, I’ll look at the roles of iodine, where it is found in food and what are the health issues with not getting enough of it.

Sleeping your way to better health

Sleep is like good nutrition for the brain. Poor sleep is like putting your brain on a junk food diet – literally. Now a growing pool of research is linking poor sleep habits and disrupted sleep patterns from shift work with adverse health problems that include obesity and metabolic conditions such as type 2 diabetes and heart disease. In this podcast, I’ll look at the sleep-health connection and explain what disrupted sleep could be doing to your food habits, hormones and weight.

Can you cure a hangover?

Hangovers are the body’s way of reminding us about the hazards of overindulgence. In this podcast, I’ll delve into what goes on behind the scenes to cause a hangover. I’ll then explore what science has to say about all those supposed ‘hangover cures’. And finally, I’ll outline the practical things that are in your control to help prevent and treat a hangover.

Food comas: why overeating makes you sleepy

Feeling sleepy after a big meal? Is moving to the couch the only activity you’re capable of after Christmas lunch? You may just have been the victim of a food coma. Food comas are a real thing. And there is plenty of science to explain why the food binge you just took part in has done what it has to you. In this podcast, I explore the food coma in all its physiological and neurological glory and explain how you can help prevent it.

Do multivitamins make you healthier?

Multivitamin supplements are big business. Pharmacy and supermarket shelves groan under the weight of choice available to us. So, if you’re serious about your health, should you be taking one of these even if it is just as an insurance policy for a less-than-perfect diet? While multivitamins won’t boost your health as much as what people believe, they do have the potential to be useful for certain groups of people. In this podcast, I’ll investigate the evidence for any health benefits of multivitamins and then tell you for which people they could prove useful and for whom they really are just a waste of money.

Five ways to cut your risk of bowel cancer

Bowel cancer (also called colon or colorectal cancer) ranks as one of Australia’s most common cancers, especially for people aged over 50. This is one form of cancer where diet and lifestyle choices play a big part in changing a person’s risk of developing it. That actually makes it a good news story because lifestyle factors are changeable. In this podcast, I’ll outline the key lifestyle habits to consider looking at that could lower your risk of bowel cancer.

Is it better to exercise fasted or fed?

To exercise fasted or fed? It’s a controversial topic with strong views coming from both camps. For those promoting weight loss, exercising fasted is often an essential criterion to ensure the most ‘fat burning’ possible. Then there is the opposing argument that you want to be well-fuelled before activity to help power the length and duration of your exercise. As with most things in nutrition, the simple logic of both camps falls down when you take into account the complexity of physiology and psychology of us as human beings. In this podcast, I’ll look at the fasted versus fed exercise debate.

How useful is body mass index (BMI)?

Carrying too much weight is linked to poorer health. But just how much weight is too much? Body fat can be measured in several different ways, with each method having its own pros and cons. Body mass index or BMI is by far the most common one as it only relies on knowing your height and weight. But with that simplicity comes flaws as those easy results can sometimes be misleading, which is why the widespread use of BMI is troubling. In this podcast, I’ll look at the different ways that body fat assessment can be made and explain why you should take any BMI label it may give you with a grain of salt.

Is cinnamon a super spice for blood sugar control?

Cinnamon is a spice that has been used around the world for thousands of years. It is far more than a food accompaniment. It’s the use of cinnamon as a medicinal agent that has scientists interested because of unique compounds found in cinnamon that appear to offer some unique health benefits. In this podcast, I’ll look at those health benefits with the spotlight firmly placed on how cinnamon may help people with diabetes keep their blood sugar levels under better control.

Chocolate and its many health benefits

Chocolate. It’s sweet, it’s tasty, we desire it and crave it. It is a food that brings immense pleasure and enjoyment. And in case you were looking for any more valid reasons to eat it, scientific research now confirms that it can be good for you. In this podcast, you’ll learn about the heart, exercise and brain health benefits of chocolate.

Detox diets: their pros and cons

Detox or liver cleansing diets have been around for many years. With astonishing claims of rapid and easy weight loss, improved health, and more energy, they offer the ultimate quick fix to get you healthy again. In this podcast, I’ll give you the essential guide to detox diets, look at the claims made versus the reality and outline my list of pros and cons for anyone considering going on a cleanse.

The perils of highly processed foods

”Just cut out processed foods if you want to be healthy”. It’s an easy throw-away line loved by nutrition wellness influencers on social media, but such advice shows naivety for what happens to food in its journey to our plate. Almost everything you eat to some extent has been processed, and not all processed foods are bad for the body. Now nutrition researchers are better defining the world of processed foods and here, it is the new term of ‘ultra-processed foods’ that you will be seeing used more in the future. In this podcast, I look at what defines an ultra-processed food and explain how they are now recognised for the unhealthy addition they make to your diet.

This is your brain on blueberries

What’s blue, round, sweet, grows on a bush and can boost your brainpower? If you answered blueberries, you would be right. Or that should be: ‘mostly right’. The ‘brain-boosting’ part needs a bit more science to catch up to the headlines, but it is looking promising that blueberries may be one food worthy of the ‘superfood’ title. In this podcast, I’ll look at the science behind how blueberries can help keep your brain healthy and functioning well throughout life.

Treating IBS with diet and supplements: what does the evidence say?

Irritable bowel syndrome (IBS) is one of the most common gastrointestinal complaints. Characterised by abdominal pain and bloating and alternating periods of diarrhoea and constipation, this chronic condition can go on to cause anxiety, depression and severely affect the quality of life of a person suffering from it. With no one single identified trigger or treatment, IBS can be a minefield for a person to try and get on top of. Diet changes are one area that can have a positive impact on IBS and in this podcast, I look at the evidence for different approaches from supplements such as peppermint oil right through to the very promising research on low-FODMAP diets.

How to decipher a research paper

Nutrition is based on science. And while the science may not always agree and even change over time, just like all scientific fields of research, without credible research to inform your views you are really just flying blind in the wind at the mercy of feelpinions and what your social media news feed shows you. The base of all scientific research is the communication of it through research papers published in peer-reviewed journals. In this podcast, I’ll show you how to delve beyond the title of a research paper and instead apply a critical filter to all parts of the research study. Developing this skill will allow you to form your own view of how much influence to give to a research study, rather than be led astray from those seeking to influence you.

Got zinc? Foods, functions and deficiencies

Zinc is an essential mineral which is needed for the proper growth and maintenance of our body. It is a key factor in helping hundreds of enzymes work and is needed for immune function, wound healing, blood clotting, thyroid function and much more. While rare, zinc deficiency in a country like Australia can occur and there are certain groups particularly at risk. In this podcast, I’ll outline the key roles of zinc, what the consequences of deficiency are and give you suggestions on the best food sources and supplemental forms of zinc.

Tracking diet trends with Google Trends

Diets are like clothing fashion trends: they come into and out of style. And if you wait long enough: back into style again. One of my favourite pop culture research tools is Google trends. Google trends keeps a global finger on the pulse of what’s hot and what’s not in the world of nutrition and diets. And tracks this over time based on the popularity of search terms. Now a research team has mined this wealth of data to produce a snapshot of the ever-changing diet trends with some surprising results.

My top nutrition myths

Can a slow metabolism be blamed for most people’s weight gain? Is celery a negative calorie food? Does microwaving food destroy nutrients? The answer to all of the questions I just posed is ‘no’. Welcome to the world of nutrition myths. Nutrition is a field where someone can be seen by the public as an ‘expert’ simply because of the way they eat and the benefits it has had for them. So, is it any wonder that nutrition is also an area that is ripe for the propagation of all manner of myths and falsehoods? Some of these myths are born from a base of science, but as science advances, these myths should be called out for what they are. In this podcast, I’ll go over some of the more popular myths I’ve come across and explain where the truth really lies.

How what you eat affects your mental health

You are what you eat, but when it comes to your mental health, what you eat can have a profound impact on your mood and how you feel. Welcome to the rapidly moving world of nutritional psychiatry which is uncovering the key links between diet and mental health. And it could just be that it is our gut microbes, through acting as psychobiotics, that are the stars of the show here, so long as they are kept fed well.

Why antioxidants in food are overrated

Antioxidants. They’re a food marketer’s dream. With promises of helping to keep your waistline slim, your heart healthy, and your brain sharp, is there anything these wonder molecules can’t do? Blueberries, dark chocolate, green tea and whatever happens to be trendy in the juice bar scene makes for a great reason to eat something delicious that can also be good for your health. But the time of antioxidants has come and gone. Nutrition science has moved on and now promotes the benefits that thousands of other natural chemicals found in foods can have – most with nothing to do with their antioxidant activity. In my latest podcast, I outline the role antioxidants play in the body and explain why food is much more than antioxidants when it comes to health.

Magnesium: foods, functions and supplemental forms

Magnesium. It is a key mineral in our body and needed for more than 300 different chemical reactions. It is also essential for muscle contractions and nerve transmission while also keeping your heart beating steadily and your immune system strong. In this podcast, I’ll outline the key functions of magnesium as well as cover the different health conditions where magnesium is thought to play a role such as heart disease and high blood pressure, diabetes, muscle cramping and poor sleep quality. And then I’ll look at the main food sources of magnesium and critique the merits of the many different supplemental forms of magnesium.

Are raw food diet claims overcooked?

Eating only raw foods has emerged as a popular dietary trend. Proclaiming an emotive health message, it is enough to make you think twice before next adding heat to your food. But fear not because on the scales of health, there is little to tip the balance in either direction. In this podcast, I look at the claims made about raw food diets and put these into context for the many health benefits that cooking food offers.

Sports supplements essentials: beta-alanine

The sports supplement market is big business, but the reality is that most of these supplements have little evidence for a benefit. It is not all negative news though because there is a small group of supplements that are backed by science and which can play a performance-enhancing role in some athletes. In this series on sports supplements, I will profile this group of supplements and for this podcast, the spotlight is on beta-alanine.

Water, water everywhere

How much water do you really need, and is possible to drink too much? In this podcast, I explain why the advice to drink ‘8 glasses of water each day’ is a myth that needs to be busted. And then I’ll outline that while even though it is very rare, it is possible for a healthy person to drink too much water with the consequences of this being potentially life-threatening. So, endurance athletes take note, this could apply to you.

Your guide to vitamin C

Vitamin C is a vital nutrient for health. It is central in the functioning of the immune system and building strong bones, skin, and blood vessels. Yet despite vitamin C being abundant in fruits and vegetables, it is also one of the most popular supplements taken, despite widespread deficiency in the population not being an issue. In this podcast, I’ll look closer at the roles of vitamin C and uncover the evidence for some of the many health claims made about it.

Shedding light on vitamin D and your immune system

Vitamin D is well-known for its role in building strong bones. But increasingly, research is revealing the importance of vitamin D in protecting against a host of health problems. Serving a dual role as both a hormone and a vitamin, it is the sun that is the main source of vitamin D with few foods being reliable sources of it. In this podcast, I outline the key roles played by vitamin D, profile the growing number of health areas linked to it especially as it relates to immunity, and discuss how you can keep your vitamin D levels up. That last point is especially important in today’s times with self-isolation now trending as 2020’s word of the year.

All things sweet: sugar and your health

Sugar. We eat too much of it, but how worried should you be about what it is doing to your health? While there can be considerable debate in many areas of nutrition science, along with conflicting recommendations on what we should eat, sugar is one food that everyone unites on in acknowledging that we eat too much of it. In this podcast, I explore the different ways that added sugar can sneak into food, explore the truths (and lies) about some of the health claims made about it, and give you tips on how to eat less of it – all with no ‘12-week sugar detox program’ needed.

Got iron? Foods, functions and insufficiencies

Iron. It’s one of our most important essential minerals and sits at the heart of oxygen transport and energy metabolism in the body. In this podcast, I put the spotlight on iron, outline its key functions and explore the food factors that control how much of it we absorb. Because iron deficiency ranks as one of the world’s most common nutritional disorders, I go into detail of the consequences of this, how deficiency is tested for and importantly, how it can be managed with diet and supplements.

The user’s guide to intermittent fasting

Intermittent fasting is currently one of the world’s most popular health trends. Characterised by alternating periods of food absence followed by periods of normal eating, promoters of intermittent fasting claim that it is the ‘metabolic key’ to unlocking weight loss, reducing inflammation, cutting the risk of diabetes and heart disease and maybe….even extending your life. This show covers what intermittent fasting is, how to do it, and what the evidence says about those long list of health claims.
