Your daily dose of useless bullshit!
If you have little white specks like these on your nails you may want to change your diet a little. A bad diet can lead to a lack of certain elements that are beneficial to you health. Zinc and iron are to micronutrients that are necessary for healthy nails. If you don't consume them you will get little marks like the ones pictured above. So do your nails a favor and eat more zinc and iron rich foods like meat, eggs, liver and nuts.
