Making informed choices for a varied & balanced diet

  • To achieve a balanced diet, each person must consume a variety of different food types to gain all the different required nutrients

  • No single food contains all the nutrients required by the human body

  • Governments produce guidance on the current recommendations for eating healthily and achieving a balanced diet

  • In the UK this is called the Eatwell Guide

    • It is recommended that:

      • Five portions of fruit and vegetables are eaten daily

      • Wholegrain and high-fibre foods are chosen

      • Unsaturated oils are chosen and small quantities consumed

      • Low-fat and low-sugar dairy options are chosen

      • More beans and pulses should be eaten

      • Two portions of sustainably sourced fish should be eaten

      • Less red and processed meat is consumed

      • Foods high in sugar, salt and fat should be consumed infrequently

      • Six to eight glasses of water (or equivalents such as tea) should be drunk every day

Meal planning

  • When planning meals it is important to take into consideration:

    • portion size

    • cost of food

Portion size

  • This will be dependent on the person/people eating the meals and their dietary requirements, lifestyle, physical activities and age

  • Large portion sizes encourage people to overeat and this can lead to weight gain and obesity

  • Too small portion sizes may lead to underfeeding people, this is particularly concerning for young children where nutrient deficiencies could be harmful

  • Guidelines given on food packets should be followed when cooking food

  • Roughly a portion of cooked vegetables the size of your fist should be eaten and meat the size of your palm

Cost of food

  • When planning meals, the cost of food needs to be accounted for

  • This will be different for individuals and families depending on their income, financial situation and budgets

  • Healthier foods, like fresh fruits and vegetables and lean cuts of meat, tend to be more expensive

  • The person planning meals (and the person paying for the food) needs to take into consideration whether it is cheaper to buy individual ingredients to prepare a meal from scratch or whether buying a ready-made meal is more cost-effective

  • Ingredients can be sourced from a range of shops and local markets to keep costs low, price-comparison websites can also be used

  • Many ingredients can be purchased to be used in numerous recipes e.g. a roast chicken may be used for a roast dinner, the leftovers used for sandwich fillings and the bones used to make a stock for soups and gravies

  • It is important to plan meals so less food is wasted which can impact the cost of food
