Nutrition
The sugar in an apple and the sugar in a soft drink aren't treated the same by your body. The difference isn't the sugar — it's everything that comes with it.
Why it matters
Most nutrition advice asks whether a food is good or bad. The discussions in this Health Area suggest that's often the wrong question. What matters is what comes with it. Its form, what it's eaten with, when it's eaten, and what your metabolism is already doing all change how your body responds. That's why the same advice can help one person and not another.
Key insights from this synthesis
- Sugar without fibre goes straight to the liver. The liver turns it into fat, and fat in the liver is where a long chain of problems begins.
- Fibre is the thing that changes the answer. An apple and a soft drink deliver the same sugar. The fibre decides how much of it hits the liver at once.
- Two of our own topics give opposite advice on the same everyday choice: what to cook with.
- Insulin starts rising years before blood sugar does. Three topics say the standard test finds the problem too late.
