A gut friendly weekly shop list, aisle by aisle

A gut friendly weekly shop is mostly plants with the fibre left in: wholemeal bread, oats, beans, lentils, frozen vegetables and berries, nuts and seeds, plus plain live yoghurt and one oily fish. The list below works in any big UK supermarket, aisle by aisle, and adds up to about 26 plant points.

There are no prices here, because they change every week and differ from shop to shop. What doesn’t change is what is in the food, and that is what this list is built on.

What makes a shop gut friendly?

Fibre, from as many different plants as you can manage. Gut friendly is not a legal term on a UK label, so a pack that says it is not telling you anything you can check. What the evidence does support is a varied, balanced diet with different sources of fibre. Adults are advised to eat 30g of fibre a day, and most of us average about 20g.

So this list is not about special products. Every item is an everyday line you should find in Aldi, Lidl, Tesco, Sainsbury’s, Asda or Morrisons, usually in an own label version. If you want the reasoning behind gut friendly claims, what gut friendly means on a UK label covers it.

What goes in the trolley, aisle by aisle?

Here is the list, one aisle at a time. The plant points column uses the usual convention: one point per different plant a week, a quarter for herbs, spices and garlic, and nothing for refined grains or animal foods.

The frozen mixed vegetables are usually carrot, pea, sweetcorn and green bean. Carrot is already in from the fresh aisle, so the bag adds three. A four berry mix, usually strawberries, raspberries, blackberries and blueberries, adds four. Mixed seeds are typically sunflower, pumpkin and linseed. Read the back of any mix, because own label blends vary.

Why are frozen and tinned on the list?

Because they count. The NHS counts frozen and tinned fruit and vegetables towards your 5 A Day, and the plant points convention counts fresh, frozen, tinned and dried the same. For tins, pick fruit in natural juice or water and vegetables or pulses in water, with no added sugar or salt.

They also keep. Fresh spinach that wilts on Thursday is a plant you paid for and didn’t eat. A bag of frozen berries is there for porridge on Sunday. If cost is the worry, the cheapest way to eat 30 plants builds a whole trolley from the freezer and the tin aisle.

Do I need kefir, kombucha or a probiotic?

No. The British Dietetic Association does not class kefir or kombucha as probiotics, because the evidence on their health benefits is lacking. If you enjoy them, buy them. They are not the foundation.

A plain live yoghurt is on the list because it is an ordinary, useful food: protein, calcium and no sugar added if you choose plain. Contains live cultures on the pot is a statement of what is in it, not a health claim. Milk, yoghurt and cheese sit in the dairy group, and unsweetened calcium fortified alternatives made from soya, oats or coconut count there too.

Why one oily fish?

Because a healthy, balanced diet should include at least two portions of fish a week, one of them oily, and most of us don’t get there. Tinned sardines, pilchards and mackerel are the easy way in. Tinned sardines with the bones left in also give you some calcium.

How do I keep this shop affordable without prices?

Use the unit price on the shelf label, the price per kilo or per 100g, rather than the price on the pack. It is the fair way to compare a big bag with a small one, or an offer with the everyday version. The BDA’s own advice for eating well on a budget adds two more: value lines often taste as good for a lower price, and the cheaper products are not always at eye level, so look at the top and bottom shelves too.

Freeze bread you won’t finish. A wholemeal loaf lasts the week that way.

Where do I go from 26 plants?

Add a few each week rather than all at once. Adding a lot of fibre in one go tends to bring bloating and wind with it, so build up gradually and drink plenty of fluid. Swap one item next week: a different bean, a different fruit, a new spice.

The 30 plants a week checklist shows how the count works over a full week. For reading the back of each pack as you go, how to read an ingredients list is the next step, and the label test is a quick way to see how you are doing.

If you have a diagnosed gut condition, check with your GP or dietitian before you change how much fibre you eat.
