Heard about flavonoids? They are just one group from a long list of beneficial natural polyphenol chemicals you’ll find in plant foods. While the chemistry and naming structure can be daunting, there is nothing daunting about the foods that contain lots of these flavonoids. In our body, these flavonoids can operate as antioxidant and anti-inflammatory agents. And that all spells good news for your heart health. In this podcast, I’ll explain what flavonoids are, what foods contain lots of them, and unveil the latest evidence linking them to good heart health.

Nut allergies are one of the most common types of food allergy seen in children and adults. Caused when the body’s immune system overreacts to proteins found in nuts or peanuts, it can lead to a range of symptoms from mild reactions to severe anaphylaxis that is life-threatening. People with a nut allergy need to avoid the nut that triggers their allergy entirely. There is hope on the horizon though. Called oral immunotherapy, it is emerging as a possible way to desensitise people to nuts and allow small amounts to be eaten safely. And that’s what I’ll be covering in this podcast.

Bowel cancer (also called colorectal or colon cancer) is the second biggest killer of Australians from cancer each year. This is one form of cancer where diet and lifestyle choices play a big part in changing a person’s risk of developing it. But once someone is diagnosed with cancer, the outlook changes. Now emerging research is finding that the use of probiotic supplements taken in conjunction with active treatments of surgery, chemotherapy or radiotherapy can have a beneficial effect on the outlook of people with bowel cancer. And that’s the topic I’ll cover in this podcast episode.

Growing up, kids are told to sit down at the table when they’re eating. Far from just being about good manners, science is now discovering how standing up while eating can change taste perception, temperature sensation and even how much is consumed. Welcome to the weird world of altered taste perceptions which is what I’ll be exploring in this podcast.

Ketogenic diets have gained popularity in recent years among athletes. While these diets are just as effective for weight loss as any other diet that causes a calorie deficit, the evidence for a real sporting advantage over other diets is very mixed and it seems only in steady-state endurance sport that they may have some role. But what about in the gym? Is keto a viable option to both shred and bulk up at the same time? That’s what I explore in this podcast by looking at the findings of a recent review paper on this very topic.

Can you cure a hangover? Do drinks with bubbles get you drunk quicker? Are darker drinks worse for you than clear drinks? Is there really such a thing as a beer gut? These questions and more are what I’ll be tackling in my annual Christmas special podcast on all things alcohol facts and fallacies.

Curcumin is the bioactive ingredient found in the popular spice turmeric. Medical science is backing up many of the traditional health claims made about turmeric and the compounds it contains. Conditions such as arthritis, high cholesterol, exercise recovery and even depression all have a growing positive evidence base of research behind them. Now a new research review has looked at the evidence for curcumin supplementation in treating some of the symptoms of PCOS. In this podcast, I give an overview of the use of curcumin in different conditions and explain how it may be effective in PCOS too.

Small intestinal bacterial overgrowth (SIBO) is a condition where there is an abnormal increase in the number of bacteria in the small intestine – especially types of bacteria not normally found in this part of the digestive tract. Most of the focus on gut health is given to the population of bacteria in our large intestine, so in this podcast, I’ll look at the consequences of what happens when bacterial growth gets out of control in our small intestine.

Many of us describe ourselves as having a sweet tooth. But science is now unlocking the secrets of why having a well-developed taste and tolerance to bitter foods could have a wealth of health benefits. But even with their many health benefits, the bitterness of foods such as broccoli, spinach and turnip can put people off. Now new research finds that the taste perception of bitter foods can change the more they are eaten.

With all the recent health focus on sugar, poor old fruit has gotten undeserved attention for the simple reason that it is high in sugar. And from that, some very average advice has surfaced that people need to limit how much whole fruit they eat. Now a systematic review puts to bed any health concerns anyone should have about fruit, finding that whole fresh fruit does not contribute to weight gain. Eat up.
