Healthy Eating for Beginners: Where to Start

Deciding to eat better is easy. Knowing where to begin is the hard part, mostly because so much advice arrives at once and so much of it contradicts the rest.

This guide ignores the noise. It is based on the plain, consistent advice of public-health bodies such as the NHS and the World Health Organization, and it is arranged in the order that tends to work: add first, adjust second, and leave perfection out of it.

Before you change anything

Three ideas make everything else easier.

You are changing a pattern. Health is shaped by what you eat most of the time, over months and years. One meal, good or bad, is a rounding error. The NHS says as much: aim for balance over a day or even a week.

There are no forbidden foods. Labelling food as good or bad tends to backfire. Some foods are for every day and some are for now and then. That is all.

Small changes last longer than large ones. Overhauling your whole diet on a Monday usually ends by Thursday. One change that survives is worth more than ten that do not.

Step 1: Add vegetables and fruit

Start here, because it is the change with the widest agreement behind it and because adding is easier than taking away.

The target is at least five portions of a variety of fruit and vegetables a day. A portion is 80 grams of fresh, frozen or tinned fruit or vegetables, which is roughly a handful: a medium apple, a banana, three heaped tablespoons of peas or carrots, a cereal bowl of salad. A portion of dried fruit is 30 grams.

Easy ways to add one:

• slice a banana or scatter berries over breakfast;
• add a side salad or a bowl of vegetable soup at lunch;
• stir a handful of frozen spinach or peas into pasta, curry or stew;
• keep fruit on the counter and have it as your first choice of snack.

Frozen and tinned count, and they are often cheaper and less wasteful than fresh. Choose tinned fruit in juice, not syrup, and tinned vegetables without added salt.

Step 2: Switch to wholegrain

Starchy foods such as bread, rice, pasta and potatoes should make up just over a third of what you eat. You do not need to eat less of them. The helpful change is to choose the higher-fibre versions.

Try swapping:

• white bread for wholemeal or seeded;
• white rice or pasta for brown or wholewheat, or a half-and-half mix while you get used to it;
• sugary cereal for porridge oats or another wholegrain cereal;
• peeled potatoes for potatoes with the skins left on.

Fibre helps you feel full for longer and supports digestion. If your current diet is low in fibre, increase it gradually over a few weeks and drink plenty of fluid, which makes the change more comfortable.

Step 3: Rethink your drinks

Sugary drinks are one of the simplest things to change, because they add a lot of sugar without making you feel fed.

Water is the best everyday drink. Tea, coffee and lower-fat milk count towards your fluid intake too. The NHS suggests limiting fruit juice and smoothies to one small glass, 150 millilitres, a day, because they are high in free sugars.

If plain water bores you, try sparkling water, or add a slice of lemon, some cucumber or a few mint leaves. For more, see Hydration: how much water do you really need?.

Step 4: Cut back gently on salt, sugar and saturated fat

Only now is it worth looking at what to reduce. UK guidance for adults sets these daily limits:

The World Health Organization's salt limit is a little lower, at less than 5 grams a day.

You do not need to count grams. A few habits bring the numbers down without arithmetic:

• Salt. Taste food before adding salt. Use herbs, spices, garlic, lemon or vinegar for flavour. Check labels on bread, sauces, soups, processed meat and ready meals, which is where much of the salt is.
• Sugar. Cut down on sugary drinks first, then on sweets, biscuits and cakes. Reduce sugar in tea and coffee a little at a time; your taste adjusts within a few weeks.
• Saturated fat. Choose lean cuts of meat, trim visible fat, and cook with a small amount of vegetable or olive oil in place of butter, lard or ghee. Grill, bake or steam more often than you fry.

Step 5: Learn to read a label in ten seconds

Food labels look complicated, but you only need two parts.

The colour coding. Many packaged foods in the UK carry a panel on the front showing whether the food is high (red), medium (amber) or low (green) in fat, saturated fat, sugars and salt. More greens and ambers, fewer reds: that is the whole method.

The "per 100g" column. This lets you compare two products fairly, whatever their serving sizes. As a rough guide used on UK labels, a food is high in sugar if it has more than 22.5 grams of total sugars per 100 grams, and high in salt if it has more than 1.5 grams per 100 grams.

The ingredients list is ordered by weight, so whatever comes first is what the product mostly consists of.

Shopping and cooking without the fuss

Plan loosely. Deciding on three or four main meals before you shop is enough to stop most impulse buying.

Stock a few reliable basics. Tinned tomatoes, tinned beans and lentils, frozen vegetables, eggs, oats, wholewheat pasta and brown rice will make a decent meal out of almost anything.

Cook once, eat twice. Make double and freeze half. Future you will be grateful on the evening when cooking feels impossible.

Do not shop hungry. It sounds trivial. It is not.

Keep the easy option healthy. If the quickest thing in the kitchen is fruit, yoghurt or wholemeal toast, that is what you will reach for.

A realistic first month

If a week goes badly, repeat it. Nothing is lost.

What comes next

Once these basics feel normal, Understanding balanced nutrition explains the proportions behind a healthy plate in more detail. But there is no rush. Eating a little better, for a long time, is the whole idea.
