Harvard vegetable soup may not achieve the expected effect only by drinking soup.

The formula of Harvard vegetable soup includes carrots, onions, potatoes, sweet peppers, tomatoes and other vegetables, which are rich in vitamins, minerals and dietary fiber. However, most of these nutrients are β-soluble, such as carotenoids such as α, β-carotene and lutein, which will not dissolve in soup.

Therefore, if you only drink soup and don't eat vegetables, you may not be able to absorb most of the nutrients in vegetables. In order to get all the benefits of Harvard vegetable soup, vegetables should be eaten with soup.
