In colonial times the life of a Pilgrim was much different than today. They did not have all of the things that are part of our normal day. They did not have any of the technology that we get to use all of the time. They couldn't just go to the grocery store and get food. They had to hunt or grow all of their own food for their families.
They said on the website that they did not have running water. It was probably hard to get the water every time that you needed it. If you needed water in the winter it would be frozen or very cold. You would have to heat up all of the water in the fire. They did have all of the foods that we have at Thanksgiving. They had many different kinds of food.
