Our bodies need adequate amounts of various elements (atoms) to form our structure and to create components needed to perform properly: calcium, iron, iodine, selenium, magnesium, zinc, sodium, potassium, phosphorous, chloride, chromium, copper, molybdenum, sulphur, carbon, oxygen, hydrogen, and perhaps others.

ATOMS such as these bond together to form the MOLECULES, which in turn form the essential components in our bodies, from the smallest enzymes, cells and vitamins, to proteins, fats, our bones, blood, skin, organs etc. 
Some of these elements are needed only in extremely small quantities, and some in much larger quantities. 

Deficiencies in any leads to sickness, or even death in extreme cases.

To have these elements available in our bodies, we need to eat them - they are found in good quantities in a variety of foods in a healthy, well-rounded diet.

As current science understands, atoms are very difficult to create or destroy.  Under most conditions, including in our bodies, atoms are neither created nor destroyed - they do however bond together to form MOLECULES, which CAN and do often form and break apart easily.  But to create or destroy ATOMS requires extreme compression, heat, and other conditions, such as in a star or a nuclear reactor.  And even then, the new atoms are created out of old atoms.  Matter itself is never created nor destroyed, it just changes form.

Our bodies form many of the molecules needed to live healthily, however many we can not make ourselves, so we need to get them from our food.  A good example is amino acids, the building blocks of proteins.  There are about 22 types of amino acid all together, and our bodies can make 14 of these with non-amino acid components.  However there are 8 types of amino acid our bodies can't make, so we have to get these from our food - these 8 are called essential amino acids for this reason.  Similarly, there are some vitamins our bodies can make ourselves - such as vitamin D, which is made out of other components when sunlight hits our skin.  However, our bodies can't make vitamin C so we need to eat this.  Vitamin C is found in fruits and vegetables, and essential amino acids in fruits, vegetables, grains, beans, and animal products.

This is what current science teaches, anyway.  This is NOT what breatharians claim.

They claim the prana can manifest all these atoms out of nothing at all, despite the fact atoms are usually only created out of something else and only under extreme nuclear-reactor type conditions.

They also claim prana can create the food elements such as essential amino acids and vitamins which usually we have to get from eating food.

Make up your own mind on this one.
