If your appetite is not very good there are two ways to add extra energy and protein to your diet, without actually having to eat more food.
If you have a good appetite, you should have no trouble eating the extra energy and protein foods that you may need if you are ill.
However, if that is not the case, the first way to increase your intake is to use everyday foods| that are high in energy and protein. The second is to use manufactured food supplements. These can be taken as nourishing drinks, which are available as milkshakes or soups. Some supplements are high-protein powders that can be added to your normal food.
Many supplements| are available to add extra energy and/or protein to your diet. They are usually available from your chemist.
Important note: High-protein supplements should only be used with advice from your doctor or dietitian. Most people will need extra energy balanced with extra protein. Many of these products can be used by people with diabetes. However, if you are diabetic, seek advice from your doctor, specialist nurse or dietitian before using food supplements.
Once mixed, complete milk-tasting supplements and powders should be drunk slowly over a period of 20 minutes.
High-energy and juice-tasting supplements have a high carbohydrate (sugar) content, and people who are diabetic should talk to their dietitian before using them.
People who have had radiotherapy for certain types of head and neck cancers| may be at more risk of tooth decay, and so should avoid having sugar too often during the day. It's a good idea to clean your teeth or use a mouthwash after any sugary snacks. Your doctor or dietitian can give you more advice about this.
