Diet when you are diabetic or at risk

There is no prohibited food in diabetes, but balances must be found. Eating well remains a pleasure, even when monitoring your blood sugar.

L'alimentation quand on est diabétique ou à risque

The diagnosis of diabetes or prediabetes is often accompanied by worry: “What else can I eat?” » The answer is reassuring: almost everything, provided you understand a few principles. Food is a central lever for stabilizing blood sugar levels, without giving up the pleasure of eating.

1. Understand the impact of carbohydrates

Carbohydrates are the nutrients that most influence blood sugar levels. It is not a question of eliminating them, but of choosing them carefully and distributing them throughout the day. Not all carbohydrates are equal: their effect depends on their nature and what you eat with them.

2. The principles of a balanced plate

PreferredLimited
All you can eat vegetablesSweet drinks
Whole grains, legumesUltra-processed products
Whole fruits (in moderation)Excess Sweets
Lean protein, good fatsExcess fats saturated

A balanced plate gives pride of place to vegetables, combines quality carbohydrates with proteins and fiber, which slows down the absorption of sugar.

3. Fiber and the glycemic index, allies

Fiber (vegetables, legumes, whole grains) slows the absorption of glucose and limits blood sugar peaks. Choosing foods with a low glycemic index and combining them intelligently helps to better regulate blood sugar levels after meals.

4. Maintain pleasure and regularity

No food is completely forbidden: it's the frequency and quantity that count. Depriving yourself completely often leads to deviations. It is better to aim for a balanced and sustainable diet, with well-integrated occasional pleasures.

    • Eat at regular times
    • Place balanced and varied plates
    • Treat yourself occasionally without feeling guilty

For personalized support, a dietician or doctor can adapt the advice to each situation.
