Hydration for an older adults is an important topic to discuss. Well-hydrated, it is vital for everyone and recommendations should be directed at 6-8 drinks a day, but you may still choose to select drinks that contain energy and nutrients if you have a low appetite or are worried about lack of weight.
Good hydration is vital because it may help avoid constipation, urine and drops and as we get older, our appetite can decline, so drinking regularly during the entire day is especially necessary.
This is important to make sure drinks are easily available in any moment while you are caring for an older person in bad health and/or with mobility problems. The risk of incontinence can mean that people limit fluid consumption, but that is not the safest way to make matters worse.
A variety of drinks, both hot and cold can help keep you hydrated, although alcoholic drinks don’t count.

Water
water is a good choice throughout the day. You could try adding mint or lemon for extra flavor.
Tea coffee and other hot drinks
Many of us enjoy these drinks and they count towards your fluid intake. Drink with plenty of milk if you want to add extra calories and protein.
Milk and milky drinks
Milk is a good source of calcium, iodine, B vitamins and protein. Whole milk can be a better choice for adults with poor appetites. To increase calorie and protein intake, why not try to include milky drinks like hot chocolate or milkshakes with added fruit and yogurt. You can also fortify your milk by blending 2-4 heaped teaspoons of dried skimmed milk powder into a pint of whole milk. Use on cereals, in porridge, sauces soups and milky drinks.
Fruit and vegetable juices
Unsweetened 100% fruit or vegetable juices provide you with vitamins and minerals. A 150ml glass counts as 1 of your 5 A DAY.
Soups and smoothies
High fluid foods, like soups, will contribute to hydration! Also, why not try smoothies as they can provide a range of vitamins and minerals.
Soft drinks
soft drinks count towards your intake but they may provide limited nutrients. Diet options are not a good choice if you are trying to prevent weight loss.
