Recommend fruit and vegetables that are rich in particular vitamins and minerals

Making Harold aware of some of the foods that he should be eating will certainly help him save time thinking about it, and will hopefully allow him to make better choices next time he goes food shopping

Provide advice on storing food to minimise nutrient degradation

Although this might be useful information, it doesn’t help address the main issue of Harold not having a healthy and balanced diet

Recommend vitamin and mineral supplements, taking into account any medications they are currently taking

A varied and healthy diet should give him all the vitamins and minerals his body needs, but because of his situation at home, a food supplement may be a good way to ensure he is obtaining them in the required levels

Refer him to a dietician

If his diet doesn’t improve it will most likely make his blood pressure and cholesterol issues worse and referral to his GP or a dietician may be needed, but at the moment dietary and lifestyle advice should suffice
