"The only food that provides all the nutrients that humans need is human milk," Hattner said. "Mother's milk is a complete food. We may add some solid foods to an infant's diet in the first year of life to provide more iron and other nutrients, but there is a little bit of everything in human milk."
However, there is no known food that supplies all the needs of human adults on a long-term basis. Since Taylor is determined to follow a one-food diet, then potatoes are probably as good as anything, as they contain a wider range of amino acids, vitamins and minerals than other starchy foods, such as pasta or rice.

Including lean protein, vegetables, and nuts in the diet every day can help people stay healthy and prevent certain chronic conditions. Some plant foods, such as cruciferous vegetables and berries, contain particularly beneficial compounds, including polyphenols and glucosinolates.
In one sense, it all comes down to math: The average adult human requires 2,000 calories per day, and you're only awake for so many hours. "Across all peer-reviewed research and health practices, three meals a day is a general recommendation to encourage consistent, adequate energy intake," Miluk said.
The short answer is yes, yes, it would, but the larger question is; is it even possible? You could probably survive on quality whole grain bread that's been fermented for a while. But eventually you would run into nutritional deficiencies, and in all likelihood, you'd eventually get sick of the carb-laden substance.
Eggs can be a healthful source of protein, but they should not be the only food a person eats. The egg diet may lead to weight loss initially, but it is not a balanced or safe weight loss plan in the long-term. Once a person returns to their usual eating pattern, they may regain the weight.
Still, if rice and beans is all you've got, it's a pretty decent choice. But "you're not going to have a complete diet," she says. The combo lacks Vitamin C and other essential nutrients. "It's extremely important that you eat meat and vegetables," Campos says.
Every American should have at least a three-day supply of food and water stored in their home, with at least one gallon of water per person per day. If you have the space, experts recommend a week's supply of food and water. Choose foods that don't require refrigeration and are not high in salt.
Rice is a food staple for more than 3.5 billion people around the world, particularly in Asia, Latin America, and parts of Africa. Rice has been cultivated in Asia for thousands of years. Scientists believe people first domesticated rice in India or Southeast Asia. Rice arrived in Japan in about 3,000 years ago.
