Can a person live off of bread, water, and tuna their whole life?

Question

I was just wandering if a person can live off of a low cal. diet of water bread and tuna.

Answer 1

Yes, but they probably will develop scurvy from the lack of vitamin C.

Answer 2

A person can survive on just about any food, but the quality of life will be in question, our body needs many more nutrients than are supplied in tuna bread and water. Anyone considering a diet such as this should seek not only the advice of a dietician but that of a psychologist.

Answer 3

You would need to take some kind of multi-vitamin to ensure you get all the proper nutrients your body needs. Although, eating that much tuna will cause high levels of mercury in your body which is very unhealthy and can be a problem.

Answer 4

Yes, but your life would be shortened by the lack of vitamins that occur in fruits and vegetables like A, C, and many B vitamins. Scurvy, the lack of vitamin C, as someone else suggested, would be one of the earlier manifestations of vitamin deficiency. The lack of fiber would lead to constipation too.

Answer 5

Probably, but I would be concerned about mercury poisoning. Adults are only supposed to have 2 servings of tuna per week.

Answer 6

You probably could live, but would be lacking in some crucial vitamins, and have very fishy smelling farts. Just being honest.

Answer 7

Probably. But ask a doctor. Sounds like they may be mal-nutritioned after a bit.

Answer 8

Yes even as his life expency dwindles to 29
Of course if he dies at 12 ??? well that is the problem with life expectancy but they lived their whole life !!! :~)

Answer 9

Man cannot live on bread alone, he needs peanut butter.

Answer 10

I think that you would suffer a vitamin deficiency. Ultimately, it would cause you to weaken and get sick and make you more susceptible to common viruses.
