How stable is your blood sugar throughout the day, and what can you do to keep it in check?
What is blood sugar? Your blood sugar level measures the glucose concentration in your bloodstream. For optimal health, it should stay between 4 and 6 millimoles per liter (mmol/L). Levels naturally fluctuate daily: they dip slightly before meals and rise after eating as glucose enters the blood. This glucose fuels your cells for energy, with insulin facilitating its uptake. Excess glucose gets stored as body fat for future use.
Why maintain stable blood sugar? Sharp spikes trigger excessive insulin release, which over time harms health and promotes visceral fat around the abdomen. Levels above 7 mmol/L signal diabetes risk, heightened by frequent fluctuations.
1. Stay active
Aim for at least 30 minutes of movement daily to help regulate glucose uptake and insulin sensitivity.
2. Prioritize low-glycemic index foods
High-GI foods like biscuits, cakes, candy, chips, canned vegetables, sauces, and crackers release fast sugars that spike blood glucose rapidly. This overworks the pancreas, leading to insulin surges followed by crashes (hypoglycemia), increasing diabetes risk over time. Break the cycle by choosing wisely.
Smart choices: Foods that support stable blood sugar
* Carbs: Quinoa, brown rice, oat bran, wholemeal bread and pasta, rye bread.
* Dairy: Skimmed milk, soy milk, 0% fat natural yogurt.
* Proteins: Eggs, fresh fish, skinless chicken, lean red meat, tofu.
* Nuts and seeds.
* Fruits: All except those listed under 'Avoid'.
* Vegetables: All except potatoes; choose beets, raw carrots, sweet potatoes.
* Oils: Cold-pressed extra virgin olive oil.
Avoid: Foods that cause rapid spikes
* White carbs: Bread, pasta, rice, flour, biscuits, sweets.
* Dairy: Butter, whole milk, yogurt.
* Breakfast: Cornflakes, muesli, cereals with dried fruit.
* Fruits: Dried fruit, juices, pineapple, mango, banana, melon.
* Drinks: Beer, wine, cocktails, sodas, fruit juices.
* Sugars: Sucrose (white sugar), honey, jam, chocolate, ice cream, chips.

3. Manage stress
Chronic stress elevates cortisol and adrenaline, disrupting insulin function and blood sugar balance.
4. Eat smaller meals throughout the day
Spacing out meals prevents overloads and maintains steady energy.
