The 5 A Day message has been around for a long time and it has been shown that the number of vegetable and fruit portions consumed per day is directly correlated to health and inversely with risk of chronic diseases.
So, it’s great if your clients are getting 5 or more portions per day (6-8 of vegetables and 1-2 fruit is even better!!) however, even if reaching that goal, many people are consuming the same types of food every day and therefore lack diversity in their diet.
