disadvantages of junk foods

hi, for me, junk food is not healthy for our health... its not good to eat junk food all the time... yup, it can cause some illness like hepatitis and kidney stone & other illness... its not advisable to eat it always or eat it a lot...in just one meal... ur not sure if junk food is clean, it have a lot of salt and sweets... we all know that too much of something is not good... have a nice day and happy mylotting.. ^_^
