Chest freezers were often kept in garages and other cold places and worked efficiently (and economically) by not having to fight central heating temperatures. I have read your column for years, and been impressed with the clear explanations you normally provide.
Amino acids are found in animal sources such as meats, milk, fish, and eggs. They are also found in plant sources such as soy, beans, legumes, nut butters, and some grains (such as wheat germ and quinoa). You do not need to eat animal products to get all the protein you need in your diet.
People should eat meat because meat provides a lot of good animal protein that human bodies need to function and thrive. Plant protein is good, but i believe meat protein is better. Many people are vegetarians for animal rights reason, but many others simply believe meat is too fattening to eat. This is not true.
