Jot down a few questions to make the most of your conversation.
Start with the type of protein
Healthy protein foods come from both animal and plant sources. There is no single “best” option for everyone, so it helps to choose a mix across the week.
In general, aim for foods that are less processed and lower in saturated fat, salt, and added sugar. These choices can support a healthier diet without making protein boring or restrictive.
Choose lean animal proteins
If you eat meat, pick leaner options such as skinless chicken, turkey, lean beef, pork loin, or fish. These provide protein without as much saturated fat as fattier cuts.
Oily fish such as salmon, sardines, mackerel, and trout are especially useful because they also provide omega-3 fats. In the UK, the NHS advises eating at least two portions of fish a week, including one oily portion.
Include more plant-based protein
Beans, lentils, chickpeas, tofu, tempeh, edamame, nuts, and seeds are all healthy protein foods. They also bring fibre, vitamins, and minerals that many people do not get enough of.
These foods can be especially helpful if you want to eat less meat. Try adding lentils to soups, chickpeas to salads, or tofu to stir-fries for an easy protein boost.
Watch the salt, fat, and processing
Not all protein foods are equally healthy. Processed meats such as bacon, sausages, ham, and some ready-made burgers can be high in salt and saturated fat.
Protein bars, flavoured yoghurts, and snack products can also contain lots of added sugar. Check labels and choose simpler options when possible.
Look at portion size and balance
Even healthy protein foods need sensible portions. A palm-sized portion of meat, fish, tofu, or beans is often enough for a meal.
For the healthiest plate, combine protein with vegetables, wholegrains, and healthy fats. This helps you feel full and supports overall nutrition rather than focusing on protein alone.
Make it practical for everyday eating
Choose protein foods that fit your routine and budget. Tinned beans, frozen fish, eggs, plain yoghurt, and cottage cheese can all be affordable and convenient options in the UK.
Planning ahead makes healthier choices easier. Keep a few simple protein foods at home so you can build quick meals without relying on takeaway or ultra-processed snacks.
