In a world overflowing with dietary advice, miracle supplements, and ever-changing wellness trends, Fuel to Thrive brings us back to the fundamentals—ten essential nutrients that your body depends on every single day. Tamsin Haleshenk offers a science-backed, deeply practical guide to understanding what your body truly needs to operate at its best, not just survive, but thrive.

From the moment you wake to the second your head hits the pillow, your body is performing a symphony of biological processes—pumping blood, transmitting signals, repairing cells, and generating energy. These intricate systems don’t run on willpower alone. They run on nutrients. And not just any nutrients—essential ones, meaning your body can’t produce them (or enough of them) on its own. They must be sourced from what you eat and drink.

In this refreshingly clear and accessible guide, you’ll explore ten of the most critical nutrients the human body relies on daily:

• Protein – the building and repair powerhouse
• Carbohydrates – your brain and muscle’s preferred energy fuel
• Fats – especially essential fatty acids, for cell structure and vitamin absorption
• Vitamin A – key to vision, immunity, and skin health
• Vitamin C – a champion antioxidant and collagen booster
• Vitamin D – crucial for bones, immunity, and mood regulation
• Calcium – the structural mineral for bones and cellular signalling
• Iron – the oxygen transporter and energy catalyst
• Magnesium – the biochemical workhorse supporting muscles, nerves, and enzymes
• Water – the silent hero behind every single process in your body

But Fuel to Thrive goes beyond the usual lists and percentages. It explains not only what each nutrient does, but why it matters in real-life terms—how it affects your energy, your immunity, your mood, your skin, your sleep, your memory, and even your risk of disease.
