Type 2 Diabetes – Health Guides

FOODS TO CHOOSE, FOODS TO LIMIT, AND SHOPPING LIST

This chapter provides clear food categories and a practical shopping guide for Type 2 Diabetes. It is designed to answer a simple question: what should be in the kitchen most of the time, and what should be rare or absent.

FOODS THAT SUPPORT GLUCOSE CONTROL

The following groups of foods generally support better glucose control and overall health when used in appropriate portions.

1.⁠ ⁠Non starchy vegetables

These provide fibre, vitamins, minerals, and volume with very little impact on blood sugar.

Examples:

• ⁠ ⁠Leafy greens: spinach, kale, lettuce, rocket
• ⁠ ⁠Cruciferous: broccoli, cauliflower, cabbage, Brussels sprouts
• ⁠ ⁠Others: peppers, courgettes, aubergines, tomatoes, cucumbers, green beans, asparagus, mushrooms

Aim:

• ⁠ ⁠Include vegetables at every main meal.
• ⁠ ⁠Fill at least half of the plate with non starchy vegetables at lunch and dinner.

2.⁠ ⁠Quality protein sources

Protein supports muscle, immune function, hormones, and satiety. It helps stabilise blood sugar by slowing the absorption of carbohydrates.

Examples:

• ⁠ ⁠Fish: salmon, sardines, mackerel, trout, white fish
• ⁠ ⁠Poultry: chicken, turkey
• ⁠ ⁠Eggs
• ⁠ ⁠Lean meat in moderate portions, if used
• ⁠ ⁠Tofu and tempeh
• ⁠ ⁠Lentils, chickpeas, beans
• ⁠ ⁠Greek style yoghurt, cottage cheese if tolerated

Aim:

• ⁠ ⁠Include a clear protein source at each main meal.

3.⁠ ⁠Healthy fats

Healthy fats do not raise blood sugar and support hormones, brain function, and satiety. Portion control remains important because fats are energy dense.

Examples:

• ⁠ ⁠Olive oil and olives
• ⁠ ⁠Avocado
• ⁠ ⁠Nuts: almonds, walnuts, hazelnuts, pistachios
• ⁠ ⁠Seeds: chia, flax, pumpkin, sunflower
• ⁠ ⁠Oily fish as above

4.⁠ ⁠Slow and supportive carbohydrates

Some carbohydrate sources, in moderate portions and combined with protein and fibre, can be part of a supportive diet.

Examples:

• ⁠ ⁠Legumes: lentils, chickpeas, beans
• ⁠ ⁠Whole grains: oats, quinoa, buckwheat, barley, brown rice in small portions
• ⁠ ⁠Root vegetables: carrots, beetroot, turnip, parsnip in moderate amounts
• ⁠ ⁠Whole fruits in modest portions: berries, apples, pears, citrus fruit

Fruit guidance:

• ⁠ ⁠Prefer whole fruit rather than juice.
• ⁠ ⁠One to two small servings per day is often suitable for many people.
• ⁠ ⁠Berries are usually the most glucose friendly option.

5.⁠ ⁠Fermented and gut supporting foods

A healthy gut microbiome is associated with better metabolic health.

Examples:

• ⁠ ⁠Natural yoghurt without added sugar
• ⁠ ⁠Kefir
• ⁠ ⁠Sauerkraut and other fermented vegetables
• ⁠ ⁠Kimchi
• ⁠ ⁠Fibre from vegetables, legumes, nuts, and seeds

FOODS TO LIMIT OR AVOID

These foods and drinks tend to raise blood sugar rapidly, increase insulin demand, and promote weight gain when used frequently.

1.⁠ ⁠Sugary drinks and juices

• ⁠ ⁠Soft drinks and energy drinks with sugar
• ⁠ ⁠Fruit juices, even freshly squeezed
• ⁠ ⁠Sweetened teas and coffees
• ⁠ ⁠Flavoured waters with added sugar

These provide large amounts of rapid carbohydrate with almost no fibre or protein.

2.⁠ ⁠Refined carbohydrates and white flour products

• ⁠ ⁠White bread, baguettes, rolls, bagels
• ⁠ ⁠Standard white pasta
• ⁠ ⁠Many breakfast cereals
• ⁠ ⁠White flour tortillas and wraps
• ⁠ ⁠Cakes, biscuits, pastries, croissants, doughnuts

These foods are digested quickly and often lead to significant blood sugar spikes.

3.⁠ ⁠Sweets and desserts

• ⁠ ⁠Chocolate bars and sweets
• ⁠ ⁠Ice cream
• ⁠ ⁠Puddings and desserts rich in sugar and cream
• ⁠ ⁠Sweetened yoghurts and flavoured milks

If used at all, these are best kept for rare and planned occasions in small portions, and ideally not in the late evening.

4.⁠ ⁠Ultra processed snack foods

• ⁠ ⁠Crisps and chips
• ⁠ ⁠Flavoured crackers
• ⁠ ⁠Many packaged snack bars
• ⁠ ⁠Processed meat products with added sugars and fillers

These often combine refined carbohydrates, unhealthy fats, and salt in a way that encourages overeating.

5.⁠ ⁠Trans fats and highly processed fats

• ⁠ ⁠Some margarines and shortenings
• ⁠ ⁠Deep fried fast foods
• ⁠ ⁠Baked goods with hydrogenated fats

These fats worsen inflammation and cardiovascular risk.

6.⁠ ⁠So called diabetic or sugar free sweets

Products labelled as diabetic or sugar free may contain sugar alcohols and other sweeteners that can still:

• ⁠ ⁠Cause digestive upset
• ⁠ ⁠Maintain a strong preference for sweet tastes
• ⁠ ⁠Lead to overeating

They are not required for good control and are usually best limited.

SIMPLE SWAP IDEAS

Small changes can significantly reduce glucose spikes.

Examples:

• ⁠ ⁠Swap sugary breakfast cereal for oats with nuts and a few berries.
• ⁠ ⁠Swap juice for water with lemon slices.
• ⁠ ⁠Swap sweets for a small portion of nuts or a piece of fruit.
• ⁠ ⁠Swap chips and crisps for carrot or cucumber sticks with hummus.
• ⁠ ⁠Swap large portions of rice or pasta for smaller portions plus extra vegetables.

EATING OUT OR ORDERING FOOD

When eating away from home, practical rules include:

• ⁠ ⁠Choose meals where protein and vegetables are clearly visible.
• ⁠ ⁠Ask for sauces and dressings on the side.
• ⁠ ⁠Replace chips or fries with salad or vegetables if possible.
• ⁠ ⁠Avoid large portions of bread before the meal.
• ⁠ ⁠Share desserts or skip them.

CULTURAL AND PERSONAL ADAPTATION

A supportive way of eating must respect cultural habits and personal preferences. The key is to:

• ⁠ ⁠Keep the main pattern: vegetables, protein, healthy fats, controlled carbohydrates.
• ⁠ ⁠Adjust the specific dishes to match local cuisine.
• ⁠ ⁠Use traditional dishes in a modified way if needed, with smaller portions of starchy components and more vegetables.

KEY POINTS SUMMARISED

• ⁠ ⁠Non starchy vegetables, quality protein, healthy fats, and slow carbohydrates form the core of a diabetes friendly diet.
• ⁠ ⁠Sugary drinks, refined flour products, sweets, and ultra processed snacks are main drivers of high blood sugar and should be limited or avoided.
• ⁠ ⁠A clear shopping list makes supportive eating easier and reduces impulsive choices.
• ⁠ ⁠Simple swaps in common meals can significantly reduce glucose spikes without requiring complex recipes.
• ⁠ ⁠Food patterns should be adapted to personal culture and taste so they are sustainable over time.
