Maslow's Hierarchy of Needs shows that physiological needs, including food and water, are humans' most basic needs.
Food is a basic necessity, and by giving food, you can ensure your donation can fulfill a beggar's need. Homeless people must use their energy to find food, so giving food to the homeless gives them more time and effort to improve other aspects of their lives.
Though you never know what a homeless person may do with cash or a gift card, you can be certain that a homeless person cannot misuse food on drugs or alcohol.
Furthermore, giving someone food guarantees that they do not need to buy a meal for themselves, allowing them to save cash for other necessities.
There is more than one way to help homeless people by giving food.
You can organize a food drive or organize ongoing donations to a specific group of homeless people in your area. You can collect leftover goods from bakeries and restaurants, making sure perfectly edible food does not go to waste.
You can also give and volunteer directly through an organization like Hashtag Lunchbag,
which prepares packed lunches for homeless people.
If you have the means to enjoy food on a regular basis, you likely have the means to spare an extra meal for a homeless person.
