Who invented 5 fruits vegetable a- day?

There's no single inventor of the "5 fruits and vegetables a day" recommendation. It evolved over time as scientific understanding of nutrition grew.

Here's a simplified history:

* Early 20th Century: Early nutritionists began recognizing the importance of fruits and vegetables for health, but specific recommendations were lacking.

* Mid-20th Century: The concept of "5 servings a day" started gaining traction, particularly in the US, based on emerging evidence linking fruit and vegetable consumption to reduced risk of chronic diseases.

* 1990s: The "5 a Day" campaign launched in the US, aiming to promote public awareness and increase fruit and vegetable consumption. This campaign was a major factor in popularizing the recommendation.

* Today: The specific number of servings recommended varies slightly depending on age, gender, and activity levels, but the general concept of "eat more fruits and vegetables" remains central to healthy eating guidelines worldwide.

So, while there's no single inventor, the "5 fruits and vegetables a day" concept emerged from collective research and public health initiatives.
