In this straightforward video, Chef Caleb breaks down the most common nutritional deficiencies affecting modern people, explaining their subtle (and not-so-subtle) symptoms, why they happen in today’s diets, and practical ways to correct them. He covers magnesium (cramps, anxiety, poor sleep), protein (muscle loss, constant hunger), iron (fatigue, brain fog), vitamin D (low mood, weak immunity), hydration, iodine (thyroid issues), omega-3s, B12, potassium, zinc, calcium, and fibre. The emphasis is on real-food solutions first, with smart supplement advice where needed, making it a clear, no-nonsense guide to feeling better by addressing what most people are unknowingly low on.
