Is Sugar the Enemy? An Honest Answer

Sugar has become the villain in almost every wellness story. That is convenient, because villains are simple — and unhelpful, because the real answer changes what you would actually do about it.

Let me be direct about where I land: added sugar, in the quantities most of us eat it, is genuinely worth reducing. But the way it gets talked about — as poison, as addiction, as the single cause of everything — is both inaccurate and, I think, counterproductive. Fear does not make anyone eat better for long.

The distinction that matters most

Added sugar is what goes into food during processing or at the table. Intrinsic sugar is what occurs naturally in whole foods — the fructose in an apple, the lactose in milk.

They behave differently in your body, and it is not because one is morally superior. An apple arrives wrapped in fibre, water and polyphenols°, so the sugar is released slowly. Apple juice arrives without any of that, and hits like a soft drink.

This is why “fruit has sugar in it” is technically true and practically misleading. In the entire body of nutrition research, whole fruit comes out well almost every time.

What the evidence actually supports

• Added sugar and inflammation. High intake is associated with raised inflammatory markers, including C-reactive protein°. The relationship is reasonably consistent.
• Sugary drinks specifically. These come out worse than solid foods containing sugar, probably because liquid calories arrive fast and do not register as food.
• Insulin resistance°. Repeated large glucose spikes° over years contribute, though total diet, body composition, sleep and activity all matter alongside.

What it is not

It is not poison. Your brain runs on glucose. The dose and the context are what matter, as with most things.

It is not the only driver of inflammation. Sleep debt, chronic stress, alcohol, and simply not eating enough vegetables all contribute. Cutting sugar while sleeping five hours a night will not get you far.

Sugar does not “feed” disease in the way the internet suggests. All your cells use glucose. Removing dietary sugar does not starve anything selectively.

And it is not a moral category. Eating a slice of your own birthday cake is not a failure of character. This framing does real harm, particularly to women who have spent decades being told food is a test they keep failing.

What actually helps

• Start with drinks. Sugary drinks are the highest-yield thing to change and the easiest to notice. Nothing else on this list comes close.
• Never eat carbohydrate naked. Pair it with protein and fat. The same food produces a much gentler glucose response when it arrives with company.
• Read labels for the aliases. Syrup, dextrose, maltodextrin, fruit juice concentrate, anything ending in -ose. Sauces, dressings, bread and yoghurt are the usual hiding places.
• Reduce gradually. Your palate recalibrates over a few weeks. Things that tasted normal start tasting cloying, and that shift does more for long-term change than willpower ever will.
• Do not replace it with sweeteners automatically. They keep the preference for sweetness alive, which is the thing worth changing.

Where I land

Reduce added sugar, especially in drinks. Keep whole fruit. Pair your carbohydrates. Stop treating it as a moral test.

That is less dramatic than “sugar is the enemy,” and considerably more likely to still be true for you in a year.
