Dietitians and the BDA have been asked many questions about nutrition and dietary issues related to the COVID-19 / Coronavirus pandemic.
We would always encourage members of the public to start by following the latest advice from governments, the NHS and public health authorities. Stay at home, protect the NHS, save lives. You can find more information here;
- UK Government and NHS in England
- Scottish Government and NHS Inform in Scotland
- Welsh Government and Public Health Wales in Wales
- Northern Irish Government and HSC Public Health Agency in Northern Ireland
This includes following social distancing guidance as issued by the Government. If you are one of the estimated 1.5 million particularly vulnerable people identified as a result of an underlying health condition or specific treatments, the government has issued specific advice.
We have also created the following Frequently Asked Questions, which we will update and add to on a regular basis.
Simply put, you cannot “boost” your immune system through diet, and no specific food or supplement will prevent you catching COVID-19/Coronavirus. Good hygiene practice remains the best means of avoiding infection.
To date, the European Food Safety Authority have not authorised any claim for a food or food component in the UK to be labelled as protecting against infection. More info here.
There are many nutrients that are involved with the normal functioning of the immune system, so we would encourage maintaining a health balanced diet in order to support immune function (include copper, folate, iron, selenium, zinc and vitamins A, B6, B12, C and D). We don't recommend any one food over another, but instead encourage eating a variety of foods to maintain a health balanced diet. See our Healthy Eating Food Fact Sheet for more tips and guidance on how to do that.
Our Older People Specialist Group and the Rooted Project created an infographic you can share.
Vitamin D works with calcium and phosphorus for healthy bones, muscles and teeth. It is also important in protecting muscle strength and preventing rickets, osteomalacia and falls.
In normal circumstances, sunshine, not food, is where most of your vitamin D comes from. So even a healthy, well-balanced diet, that provides all the other vitamins and nutrients you need, is unlikely to provide enough vitamin D if you aren't able to get enough sun. During autumn and winter months when we spend more time indoors and the sun is weaker, adults and children over the age of one are advised to take a daily supplement containing 10 micrograms of Vitamin D.
Now we are in spring, if you can, you should seek to spend some time outdoors in the sunshine (e.g. your garden or balcony). However, if you are having to self isolate or if you are unable to go outside, you should consider taking a daily supplement containing 10 micrograms to ensure a healthy vitamin D status (for adults and children over the age of one).
All babies under one year should be given a daily supplement of 8.5-10 micrograms unless they have more than 500mls of fortified formula milk.
You can also eat plenty of vitamin D rich foods, including:
- Oily fish such as salmon, sardines, pilchards, trout, herring, kippers and eel contain reasonable amounts of vitamin D.
- Cod liver oil contains a lot of vitamin D, but don’t take this if you are pregnant.
- Egg yolk, meat, offal and milk contain small amounts, but this varies during the seasons.
- Margarine, some breakfast cereals, infant formula and some yoghurts have added vitamin D.

What general nutrition advice would you give for an someone who may have contracted COVID-19 and is self-isolating as a result?
If you feel you cannot cope with your symptoms at home, your condition is worsening or you have had symptoms for more than seven days, visit NHS 111. Do not go to a GP, pharmacy or hospital.
If you are self-isolating and especially if you have symptoms, it is important to maintain good nutrition and hydration. Make sure you are eating and drinking regularly, even if you have low appetite.
- You can find more information on eating a healthy diet in our Healthy Eating Food Fact Sheet
- We have more information on staying hydrated in our Fluid Food Fact Sheet
If you are in an at risk group or you are concerned about someone who is, please read some of our more detailed questions below.
If you have specific nutrition needs, it is important that you continue to follow the dietary recommendations made by your dietitian or other healthcare professional. This may involve asking friends or family members to get you specific foods so you can continue to follow an appropriate diet.
Contact your dietitian or other healthcare professional in a safe way if you have serious concerns.
Firstly, there is no need to stockpile or buy more food than you normally would. Although you should seek to keep shopping trips to a minimum, if you are not ill and are only undertaking social distancing, you can still visit the shops to buy normal supplies. The government has no plan to close supermarkets and any shortages at the moment are being caused by panic buying. If you are sick and need to self-isolate, in most cases it will only be for two weeks. If it for longer, ask friends or family to provide supplies, or order food for delivery.
We’ve also got some tips from our Food Services Specialist Group to help you plan your shop and how to make best use of the food that you buy:
- Use up your fresh ingredients first. You don’t want any food to go to waste, so use up perishable ingredients before foods with a longer shelf life.
- Know what keeps longest. Fresh foods with relatively long shelf life includes root vegetables such as potatoes, sweet potatoes, carrots, onions
- Carefully wash, rinse and drain salad leaves and fresh herbs and spin dry in a salad spinner, place into a suitable plastic storage tray, cover and keep refrigerated. By following this procedure your salads and fresh herbs will last for several more days than if just stored in the fridge un-covered.
- It might seem obvious but make sure you aren’t storing things in your fridge that don’t need to be in there. For example, fresh tomatoes, un-peeled onions, un-peeled jacket potatoes, whole butternut squashes don’t need to be stored refrigerated. Removing these items from your fridge and storing them in a cool dark place will free up fridge space for more perishable items.
- If you are stuck at home, take the opportunity to tidy and declutter your kitchen cupboards to free up space for ambient food products. This is a great opportunity to get rid of those unused & unwanted items that end up “living” in your valuable storage space. Remember to re-cycle as many of the items you are discarding as possible.
- If you do get sick, it is worth having a few easy to cook and prepare foods in the house on standby. Canned soups, microwavable rice and frozen ready meals are easy options that you can keep in stock in reasonable quantities if you don’t have the energy to prepare more complex recipes.
If you’re looking for recipe ideas or more advice on cooking and food preparation, our Let’s Get Cooking programme have some great advice.

Love Food Hate Waste have some fantastic advice on what you can do to minimise your waste.
It is very unlikely that you can catch coronavirus from food. COVID-19 is a respiratory illness. It is not known to be transmitted by exposure to food or food packaging.
Please continue to follow general food safety advice; washing hands thoroughly, cleaning surfaces and separating raw meat/fish from other foods when preparing food.
Public Health England have published guidance on COVID-19 for food businesses which should be followed to minimise the risk of infection from employees.
What appropriate alternatives are there for blended diets and food allergy if there are food shortages?
At this time we cannot recommend alternative products for those using blended diets and those with food allergies as there is limited knowledge on availability across the UK day to day. Please continue to check food labels for nutrition and allergen information when looking for alternatives, and where necessary, we advise age appropriate vitamin and mineral supplements daily.
It is understandable that many people will feel anxious or upset about the COVID-19 outbreak and the impact that it has on their lives. This is a stressful time and looking after your mental as well as your physical health is important.
Our colleagues at MIND have some great resources to help, including on planning for self isolation, looking after mental wellbeing and accessing further support.
Public Health England have also published advice on mental health and wellbeing. Key tips include:
- Keep connected
- Support and help others
- Look after your sleep
- Manage difficult feelings and talk to others
- Get the facts
You can also read our Food and Mood Fact Sheet to consider how your diet impacts your mental health.
Our colleagues at the Royal College of Occupational Therapists have created ten key tips to help you maintain your health and wellbeing distancing or needing to isolate yourself. This includes setting yourself goals and maintaining good sleep patterns.
Professor Rachel Batterham from the RCP has developed a series of videos (featuring dietitian Dr Adrian Brown!) which show how people of different ages and abilities can stay fit and healthy even while staying at home. Take a look:
Many people who fall into the at-risk group and have been advised to follow stay at home, are also those considered to be at greater risk of malnutrition.
Malnutrition is a serious condition which can increase a person’s risk of infection as well as slowing down their recovery. Those with an infection are also at higher risk of developing malnutrition which slows their recovery.
Malnutrition is also more common for older people and those who are already socially isolated. Social distancing and social isolation could impact a person’s access to the wide variety of foods needed to keep healthy and may make them want to eat less.
Malnutrition can also increase the risk of frailty, which is also more common in older age. Frailty can lead to weaker muscles and make people more vulnerable to infections, falls and needing extra care.
Unintentional weight loss due to disease or infection is not good, whatever someone’s original body weight was. Healthy eating in older age may look different to the general healthy eating guidelines. This is because older people are more at risk of malnutrition. Some older people may need reassuring that their diet should be different.
Read our Malnutrition Food Fact Sheet for more info.
Individuals (or their family member or friends) can self-identify whether they need nutritional help or extra nourishment here.
Health and Social care staff are recommended to screen at risk groups using the malnutrition universal screening tool (‘MUST’).
If you are unable to weigh someone due to self-isolation measures then the two part nutrition checklist can be used to guide and support action found at the bottom of this link.
Care Home staff are recommended to continue screening their residents for malnutrition using ‘MUST’.
Our Malnutrition Food Fact Sheet has lots of information and advice on preventing and treating malnutrition, including a nutrient dense diet.
It is important older people are still encouraged to keep active. Ideas for useful activity, including those that can be done at home, can be found here. Good nutrition, including eating enough protein, is essential to protect people’s muscles including respiratory muscles to help with breathing.
Vitamin D can also help protect our muscles and taking a 10 microgram supplement each day (which can be purchased from any pharmacy or supermarket) is also advised for the winter months, people who are housebound and those not receiving much daylight. Find lots more tips and information in our Vitamin D Food Fact Sheet.
Getting enough fluid is essential for good health, and you will need more fluid than usual is you have an infection. Adults are usually advised to have 6-8 mugs or large glasses a day, but this may need to be higher for someone with a high temperature. See our Fluid Food Fact Sheet for more information about how to get the fluid you need.
Our Older People Specialist Group and the Rooted Project have created an infographic with eight top tips on helping keep older people well that you can download here.
If you are supporting or thinking about someone who is vulnerable to malnutrition, consider the following:
- Can they access supermarkets and food outlets to purchase food and drink or have they been asked to remain at home?
- Do they have enough food and drink in their house to meet their nutritional needs?
- Do they have access to ingredients that they can use to increase the nutrient content of meals and fluid if they are at risk of malnutrition?
- Do they have a store cupboard of non-perishable basic foods, pre-prepared and/or frozen meals? See our advice on essential store cupboard items.
- Can they be linked to local social prescribing teams or adult social care via their local council?
- Can they access meal home delivery services such as Wiltshire Farm Foods, Oakhouse Foods, Parsley Box or a local council meals on wheels service?
- Can they maintain communication by telephone and technology to reduce social isolation?
Our colleagues at Diabetes UK have produced an excellent resource answering lots of questions for people living with both type 1 and type 2 diabetes which we would recommend you read.
If you have Coeliac Disease, it is important that you continue to maintain a gluten free diet even during social distancing or if you have to isolate as a result of symptoms. As Coeliac Disease can also impact on spleen function, you should consider yourself as "at high risk" and take the recommended precautions as a result.
Our colleagues at Coeliac UK also have some further excellent advice which we would encourage you to read.
If you have Crohn's or Colitis and are following a recommended diet, you should continue to do so.
Our colleagues at Crohn's and Colitis UK have some excellent advice that we would recommend you read.
They recommend that you do not stop any treatment you are undergoing. If you are taking an immunosuppressive / immunomodulating medicine you would be categorised as "at high risk" and should take the recommended precautions as a result.
We understand that some people are concerned that they can’t currently access specialist allergy products because of high demand in shops. Hopefully this will be resolved soon as supermarkets introduce more stringent measures to prevent panic buying.
It remains important that you maintain any diet recommended for you or your child by a dietitian or healthcare professional, and this may mean eating a more limited range of foods that usual for a short while. You or children won’t be harmed if this is in the short term, and if you are concerned about specific micronutrient deficiencies, you may wish to consider a vitamin and mineral supplement in the meantime, and these remain easy to access.

If your child uses specialist formulas, please see our FAQ below on this topic under “Pregnancy and Babies”
Pregnancy, babies and children
The Royal College of Paediatrics and Child Health and Royal College of Obstetricians and Gynaecologists have issued wide ranging advice relating to COVID-19 / Coronavirus and breastfeeding and pregnancy. They make the following recommendations:
"At the moment there is no evidence that the virus can be carried in breastmilk. The well-recognised benefits of breastfeeding are likely to outweigh any potential risks of transmission of coronavirus through breastmilk.
"If you have any concerns about how you feed your baby, you can discuss these with your maternity team.
"However, you feed your baby, the following precautions are recommended:
- Wash your hands before touching your baby, breast pump or bottles
- Try and avoid coughing or sneezing on your baby while feeding
- Consider wearing a face mask while feeding, if available
- Follow recommendations for pump cleaning after each use
"If you choose to feed your baby with formula or expressed milk, it is recommended that you follow strict adherence to sterilisation guidelines. If you are expressing breast milk in hospital, a dedicated breast pump should be used."
This guidance may change as knowledge evolves, so please refer to the RCOG or RCPCH website for up to date advice.
If you have concerns about pregnancy and COVID-19 we would recommend you read guidance from the Royal College of Obstetricians and Gynaecologists. The TUC has also published a blog looking at the employment rights of pregnant women who many need to isolate themselves.
If you are pregnant, you are more vulnerable to getting infections than a woman who is not pregnant. If you have an underlying condition, such as asthma or diabetes, you may be more unwell if you have coronavirus.
I’m concerned about supplies of infant formula, free-from milks and other products, what should I do?
Images of empty shelves and stories of shoppers fighting for food provisions has triggered panic buying across supermarkets in the UK. The UK government has advised that people should plan ahead on what is needed for self-isolation in the specified time frame only. Do not be misinformed by articles suggesting stockpiling beyond government advice. Follow the advice of UK supermarkets to avoid risking food shortages to others.
The British Specialist Nutrition Association (BSNA), which represents manufacturers, have stated all infant formula companies are continually monitoring supply and demand in the UK. If you are concerned, or require specific information, all infant formula companies can be contacted via their careline services. In the extreme case of shortages, please look for guidance directly from the manufacturers on using appropriate alternatives.
There have been claims that some infant formula companies are making free provisions to those unable to gain access to infant formula. This is not the approach of any infant formula company in the UK currently.
It is very important that you follow the manufacturers normal instructions on how to prepare your infant formula, unless otherwise advised by your healthcare professional. 'Watering down', manipulating or diluting the formula as a way to ‘ration’ your stock of powdered infant formula is not a good idea as the formula will no longer provide sufficient nutrition to your child.
For healthy infants over six months, cow’s milk (or alternatives where applicable) may be used in complementary foods, and as a main drink in those over one year. Offer other sources of calcium rich foods and continue to provide a varied diet, or where necessary, an age appropriate vitamin and mineral supplement daily.
If breastfeeding and using infant formula, consider replacing formula feeds with breastfeeds. If breastfeeding has been stopped, it is possible to re-start breastfeeding (contact the National Breastfeeding Helpline for assistance).
Some manufacturers have provided further information about accessing their products:
Should I be considering introducing complementary feeding / weaning early if there are infant formula shortages?
There have also been claims that parents of infants should consider early introduction of complementary foods in light of the COVID-19 outbreak and potential infant formula shortages. This is not official advice.
Most infants should be offered complementary foods from around six months of age, only when they are developmentally ready. Some infants may begin complementary feeding after four months of age (but not before seventeen weeks). This should only start when developmental readiness has been achieved. Parents and caregivers should consult a healthcare professional when deciding to do this.
Our Complementary Feeding Food Fact Sheet has lots more information about how and when to start this with your child.
Governments across the UK have announced support for families whose children were in receipt of free school meals. If you haven't been contacted or supplied by your school already, they should be providing support in some way. The process differs from country to country:
- In England, the UK government have made it clear that they expect all schools to continue to provide support to FSM pupils if the school is only partly open or even closed. This may be by provision of a meal that can be picked up or delivered, or by the provision of a voucher/credit to families that can be spent in a supermarket. A national scheme using 'Edenred' online portal. Read the guidance here.
- In Scotland, the same expectation in in place and the Scottish government has created a specific fund set aside for local authorities to use. Read their policy here.
- In Northern Ireland, the government will pay families directly who were previously in receipt of free school meals, using the same method as payments made for uniforms. Read more here.
- In Wales, the government has followed a similar approach to England, but also suggested direct BACS payments can be made to families. Read the guidance here.
