Can someone survive by eating only fish?

Answer 1

Yes, vegetarians live normal healthy lives. As do vegans (those who choose not to eat any animal products including dairy or eggs. Every single nutrient we humans need for a happy healthy life is available in a plant-based form.

Answer 2

Yes but you have to make sure you get your daily need of protein through other food sources. (our daily need: 0,8 to 1 gram protein per kilogram of body weight)

Protein is one of your body's important building blocks and must be incorporated in your daily diet for optimal health.

Most people get their daily need through meat, fish and dairy. But most plants actually contain protein, some even exceed the protein quantity of beef, chicken, fish, and dairy.

If you still eat fish and dairy then there should be no problem in meeting your daily need. But if you decide to become a vegetarian or vegan you should add more plant-based protein to your diet. Actually even if you eat meat or fish you should reduce your intake and add more plant-based proteins to your diet.

They provide a wide range of healthy nutrients such as antioxidants, fiber, vitamins, and minerals; and most of them neutralize acid-forming metabolites.

Here are a few examples of foods rich in plant protein: avocado, goji berries, chia seeds, flax seeds, Brazil nuts,almonds, beans, quinoa, etc.

Answer 3

You don't need meat in your diet, and you won't get sick from not eating it, but there are some risks to not eating meat. What it provides for you is protein and a lot of people who don't eat meat don't get enough protein. If you plan to go vegetarian, make sure you get plenty of protein in your diet because you can get sick from lack of protein.

No. You need other forms of protein and sugars and carbohydrates in your diet. Eating only fish would provide you with some of those, but not all.
