Probiotics, prebiotics, synbiotics, postbiotics: which actually work? 🦠 I sifted the latest trials. The strongest evidence? Fewer, shorter colds. The surprise? Some dead bacteria work as well as live ones. For mood, sleep and weight, it’s promising but early. Here’s what to check on the label.
Most of us eat only half the fibre we need. Yet fibre keeps you regular, feeds your gut bacteria, lowers cholesterol, may help dissolve blood clots and is linked to less heart disease, diabetes and bowel cancer, and a longer life. Discover how to close your fibre gap 🌾
Is BMI telling you the whole story? Two people with the same BMI can face very different health risks. Discover how hidden belly and liver fat drive disease, why muscle and bone loss can hide behind a “normal” weight and how obesity is being redefined beyond the scale.
🥩 Can you live on meat alone? The carnivore diet is all over social media, but what does the science say? Scurvy, zero fibre, bowel cancer and a surprising twist on epilepsy: my new plain-language summary explains it all, with every claim referenced. 🔍 Read it before you ditch your veg! 🥦
How effective are modern weight-loss medicines such as semaglutide and tirzepatide, and what are the risks? This plain-language summary reviews the evidence on benefits, side effects and weight regain after stopping treatment, and explains why preserving muscle and bone is essential.
Is weight gain really just about eating too much and moving too little? Here, I explore the surprising web of causes behind overweight and obesity, from pregnancy and sleep to stress, screens, food environments, poverty and pollution and explain why understanding beats blame.
Most of us eat too much salt, a few eat too little, and the shaker is rarely the main culprit. Here I unpack what salt really is, whether "natural" salts are better, why iodine matters, how much sodium is just right, and who needs more rather than less.
Homocysteine is a natural amino acid linked to heart, brain and bone health. Discover how folate, B vitamins, choline, diet, genes and lifestyle affect your levels, what raises or lowers homocysteine and why lowering it does not always translate into better health outcomes.
Vitamin C (ascorbic acid) is an essential nutrient found abundantly in fruits and vegetables. In Part 1, discover how vitamin C supports collagen formation, wound healing, immune function, antioxidant defence and many other vital processes, why deficiency can lead to scurvy, and who is most at risk.
Eggs are affordable, versatile and nutrient-dense foods that provide high-quality protein and essential nutrients. This evidence-based review explores their effects on heart health, diabetes, cognition, growth, weight management and healthy ageing.
Cow’s milk is a nutrient-dense food that provides protein, calcium and vitamin B12 to support bones, muscles and overall health. For most people, milk, maas and yoghurt are safe and beneficial, but tolerance varies and effects depend on the type consumed and the overall diet.
Riboflavin (vitamin B₂) is essential for energy production, redox balance, and iron metabolism. Found in dairy, meat and fortified foods, it supports multiple metabolic pathways. Although deficiency is uncommon, suboptimal intake may impact fatigue, anaemia and chronic disease risk.
