For a healthy diet

5 al Dia


General Questions about 5-a-Day

  • What is ‘5-a-Day’?

    ‘5-a-Day’ is a campaign to promote the consumption of five daily portions of fruit and vegetables. It is run in 40 countries worldwide through different institutions, associations and companies, where it takes different formats but has the same end goal: to make people aware of the importance of consuming fresh fruit and vegetables to maintain a healthy balanced diet.

  • Why should we consume five portions?

    Because, according to recommendations by doctors and dieticians, five portions of fruit and vegetables is the minimum amount a human being needs for proper nourishment. These recommendations are in line with the World Health Organization’s current recommendations for a healthy diet.

    Fruit and vegetables provide the human body with essential nutrients because they are rich in vitamins, mineral salts, fibre and carbohydrates. However, this isn’t the only reason we need to consume five or more portions on a daily basis. The prevention of diseases that appear in adulthood has to start in the formative years of our lives. Later, as adults, fresh produce consumption will consolidate healthy eating habits, which will be the basis for maintaining proper nutrition and a good level of health.

  • What is a portion?

    A portion can be defined in different ways. We can define it as the number or amount of fruits or vegetables that can fit into one hand. Examples of portions are an apple, an orange, one-and-a-half kiwis, a medium-sized dish of vegetables or a bowl of fruit salad.

    A portion can also be the right amount or portion of food for a ‘normal-sized’ dish for each person at the table. A portion of fruit and vegetables would be: for large fruits such as watermelon or melon, a good serving; for medium-sized fruits such as apples, bananas and oranges, one piece of fruit; for small fruits like grapes, as many as can fill a milk glass. A glass of 100% natural fruit or vegetable juice (150 ml), a bowl of salad, half a cup of peas or ¼ of cup of nuts are other portion measurements. (Source:

  • What role do fruit and vegetables play in the food pyramid?

    A very important one. After water, fruit and vegetables are the foods we should eat most often and in the largest amounts in order to maintain a balanced diet. This explains why they form the base of the pyramid.

    Obviously, no one food provides all of the nutrients our organism needs. Only a variety of produce and the consumption of adequate portions of each will help children grow as they should.

Questions related to the health benefits of fruit and vegetables

  • How do fruit and vegetables benefit our organism ?

    Fruit and the vegetables supply essential nutrients for the human body because they are rich in vitamins, mineral salts, fibre and carbohydrates. If you’d like to know the specific benefits of each food group, visit the Benefits of Fruit and Vegetables section.

  • How important is the colour of fruit and vegetables?

    We can classify fruit and vegetables into five colours: red, green, purple, white and yellow/orange. Each colour has different chemical compounds (phytochemicals, or plant chemicals) which supply different health properties. So to reap all of the benefits of the different phytochemicals we have to eat fruit and vegetables of different colours. Including fruit and vegetables of each colour also makes it easier to consume the five recommended daily portions.

  • What are phytochemicals?

    Phytochemicals are bioactive compounds found naturally in fruit, vegetables and legumes, and which help the organism to prevent diseases such as cancer. Some of them have an antioxidant action.

  • What are antioxidants?

    Antioxidants are chemical compounds naturally present in most fruits and vegetables. They are important because they prevent cell damage, since they stabilise the “oxidants” or “free radicals” that naturally form in our organism when oxygen is used. Certain vitamins have an antioxidant effect (C, E, carotenoids, beta-carotenes), several chemical substances found in foods (phytochemicals) and other compounds such as phytoestrogens, glutathione, certain phenols, flavonoids, etc.

    Antioxidant properties are present not only in fruit and vegetables but also in other foods such as tea, and spices such as oregano.

  • Why is it important to consume fibre?

    Fibre reduces glucose absorption, helps lower cholesterol levels, makes us feel fuller and prevents constipation. On the whole it is found in fruits, vegetables, legumes and wholegrain cereals such as oats, barley and rye.
