PHILADELPHIA (CBS) – It’s World Food Day and there are small measures everyone can take that make a huge difference regarding the world’s food supply.

Vicky Rateau with Oxfam America says on World Food Day, her organization, which helps folks out of poverty, encourages you to consider small changes regarding your food.

“Eating less meat and dairy, which demands a lot of resources. It also includes things just like cooking smarter, putting a lid on your pots you’re helping save energy or using a flat-bottom pan and also storing food better so they don’t waste so much.”

She says about a third of the food that’s produced goes to waste.

“It’s a huge problem. I mean, if we just look at apples — Americans waste about 2.7 billion apples. We just throw them away because they rot; and so we can store those apples which means that we’re using less soil, less water.”

She says on World Food Day, folks are encouraged to get together with friends or family for a meal and discuss these issues.
