It's not possible to provide an exact number of vegetables in the world due to their vast diversity. Nutrition guidelines recommend 3-5 servings of vegetables per day for adults, including older individuals. In a large university cafeteria, veggie-burgers represented a small fraction of total burger consumption.
Quantifying the exact number of vegetables in the world is challenging due to the vast diversity of plant species and their variations across different regions. However, historically we have seen efforts to cultivate vegetables for human consumption increase greatly. For example, in 1945 there were roughly 20 million gardens that produced 40% of the vegetables consumed in America.
For nutrition purposes, it is recommended that adults, including a 61-year-old woman who does not exercise regularly, consume three to five servings of vegetables each day. Vegetables are vital as they are a good source of vitamins A and C, minerals, and fiber. They are also low in calories but high in nutrients
Within educational settings such as a large university cafeteria, the consumption of vegetables can be seen in choices such as soybean-vegetable burgers. Out of 889,875 burgers eaten during a school year, 997 of them were veggie-burgers. This represents a fraction of 997/889875 and when calculated, it gives a certain percentage of the total burger consumption.
The probable question may be:
How has the cultivation of vegetables for human consumption evolved over time, and what historical example illustrates this trend, such as the 20 million gardens in 1945 producing 40% of vegetables consumed in America?
