See your Sainsbury's shop more clearly when managing prediabetes
A weekly Sainsbury's shop is rarely one type of food. Own-brand basics sit next to branded favourites, the same cupboard staple comes in several versions, and it can be hard to tell which differences actually matter for blood sugar.
Review an eligible Sainsbury's online shop before checkout, or forward an eligible Sainsbury's online receipt or order confirmation afterwards, and PrediabetesBasket turns the whole basket into simple educational feedback.
One-time free introductory analysis — a simpler first look at your shop. Paid membership provides the fuller, more detailed personalised Basket Review.
How PrediabetesBasket works with your Sainsbury's shop
- 1
Fill your trolley as usual
There's no shopping list to follow. The feedback is built around the groceries your household already buys.
- 2
Review before checkout, or send it after
Check an eligible Sainsbury's online shop while it's still in your trolley, or forward the online receipt or order confirmation once the order is placed.
- 3
Read your Basket Review
Own-brand and branded items are considered side by side, as part of one shop rather than a list of separate purchases.
- 4
Pick one or two things to try
You'll see what already looks good, what might be worth comparing again, and alternatives that fit the way you shop.

Comparing foods beats chasing a “perfect” basket
Most useful decisions in a Sainsbury's shop are comparisons: this loaf or that one, this yoghurt or the bigger pot, this ready meal or the version next to it. Very few of them are about banning a food outright.
PrediabetesBasket looks at the pattern across your basket — carbohydrate sources, fibre, fruit and vegetables, protein foods, drinks, snacks, saturated fat, salt and how it all balances out.
That means an occasional treat doesn't sink the shop, and one virtuous item doesn't carry it either. What matters is the overall shape of what you buy week to week.
Label comparisons worth making at Sainsbury's
Own-brand and branded products often sit within a whisker of each other. The label is the quickest way to tell.
- Bread: compare fibre per slice, and check whether “multiseed” or “brown” is actually wholemeal.
- Cereals: compare sugars and fibre per 100g between two boxes you'd both be happy to eat.
- Yoghurt: plain versus flavoured, and how the sugars change once you look at the pot size you finish.
- Drinks: where juice, smoothies and sugary soft drinks appear, and whether a no-added-sugar version works for you.
- Ready meals: saturated fat, salt and fibre, alongside the portion the pack actually contains.
- Snacks: how the multipack you buy compares with a similar option on fibre and portion size.
