Type 1 and type 2 diabetes: nutritional support
Diabetes is managed day by day through food, physical activity, sleep and — when needed — medical treatment. The practice helps you stabilise your blood sugar without giving up the pleasure of eating.

Three situations, three approaches
Insulin treatment; carbs are spread out to match dosing.
Nutrition, physical activity and sometimes medication as first-line care.
Blood sugar already high but not yet diabetic; improvement is possible, never guaranteed.
Diagnosis and treatment remain defined by your doctor; nutrition adapts to them.
Understanding blood sugar with diabetes
Post-meal blood sugar depends on the amount of carbs eaten, their glycemic index and load, and on the fibre, protein and fat present in the meal.
Individual factors also play a role: insulin sensitivity, recent activity, sleep and stress.
Spreading carbs across the day, favouring low- or moderate-GI sources and always pairing fibre with protein reduces glucose spikes and post-meal fatigue.
Foods to prioritise every day
No food is strictly forbidden. Some simply bring more benefits than others for blood-sugar balance.
- Legumes: lentils, chickpeas, kidney beans, broad beans — 2 to 3 times a week
- Whole grains: oats, quinoa, brown rice, wholegrain bread — one portion at every main meal
- Cruciferous and leafy green vegetables at every meal
- Oily fish (salmon, sardines, mackerel) 2 to 3 times a week
- Unsalted nuts: almonds, walnuts, cashews (30 g/day)
- Berries (blueberries, raspberries, blackberries) rich in polyphenols — 1 portion a day
Coordination with your doctor
A detailed report is sent to your GP, endocrinologist or diabetologist after the initial assessment and at every key stage. The goal: adjust the eating plan to lab results (HbA1c — average blood sugar over about 3 months —, capillary glucose, lipid profile) and to any treatment changes.
What belongs to your physician
Diagnosis, tests and medical treatment remain your doctor's responsibility. Dietetic support adapts to them and, with your agreement, a report is sent to your doctor.
Your first consultation, in practical terms
The initial assessment consultation (anamnesis) lasts 60 minutes, both within the CNS-covered pathway and as a private consultation. Here is what is useful to bring and what is covered.
Useful to bring
- Your latest HbA1c result and recent lab tests.
- Your blood-glucose readings, or your sensor data if you use one.
- The list of your treatments with their doses, insulin included.
- Your medical prescription and social security card if CNS coverage is intended.
What is explored
- How carbohydrates are spread across the day and how that links to the values you record.
- Timing of meals, treatment and physical activity.
- Situations that destabilise blood sugar: late meals, eating out, hypoglycaemia.
- The HbA1c target set with your physician, which the eating plan adapts to.
What you may receive
- When a personalised eating plan is drawn up, it accounts for your treatment and your schedule; it is presented during the 45-minute consultation dedicated to it (act ZD12 within the CNS pathway, a private consultation outside it).
- Meal-composition markers aimed at limiting post-meal spikes.
- A report sent to your GP, endocrinologist or diabetologist.
How progress is assessed
- Comparing your pre- and post-meal readings with the matching meals.
- HbA1c remains monitored and interpreted by your physician; the plan is adjusted accordingly.
- Follow-up takes place in dedicated 30-minute consultations, at the practice or by video. Their pace is agreed with you, with no fixed frequency.
If the recommendations are hard to follow
If the markers do not hold day to day, the change targets one meal at a time — the one whose recorded values deviate most. Any adaptation involving treatment or insulin doses is for your physician, never for the eating plan alone.

Frequently asked questions about diabetes
Legumes, whole grains, green vegetables at every meal, oily fish 2–3 times a week, unsalted nuts (30 g/day) and polyphenol-rich berries.
Yes — whole fruit (not juice) remains recommended. Favour low- or moderate-GI fruits (berries, apple, pear, citrus) and pair them with protein or nuts.
