Brittleness of the nails means that the fingernails easily become cracked or split. It is often a sign of aging. If your nails are brittle, you should check your hormone levels as it’s often a sign of low thyroid, also called hypothyroidism. The great news is that some foods can help get your thyroid working properly. Avocado and potatoes are excellent sources of tyrosine, an amino acid whose low levels are linked to hypothyroidism. Cranberries provide iodine. The thyroid gland requires iodine for normal function. Half a cup of cranberries contains 400 mcg of iodine. Try also taking Omega-3-rich foods because deficiencies of this fatty acid have been linked to lower thyroid hormone levels. Add two tablespoons of flaxseed oil to your cereal or smoothies. Also, you need to know that thyroid issues take some time to treat so that you won’t see a difference in the appearance of your fingernails for a full growth cycle.
Distinct nail ridge lines often become more numerous or prominent due to the mineral silica, iron deficiency or, with age. The reasons are variations in cell turnover and the nail’s increasing inability to retain moisture. As we age the nail matrix becomes vestigial, which results in longitudinal ridging of nails. However, if the ridges run horizontally, they may indicate a health problem.
Breakfast muesli made with raw soaked oats eaten daily supplies lots of silica. Barley bread is also a good source of the mineral. To keep your fingers fit, up your intake of silica-rich foods and pair them with iron-rich foods (fortified cereals, eggs, spinach).
Soft, weak nails
Your nails are composed of laminated layers of a protein called keratin. Since Keratin is the main protein that holds the structure of your nails together, start with healthy foods that can increase keratin levels. If you regularly eat meat, eggs, quinoa, beans or other protein-rich foods, you don’t need to worry. These foods will ensure you’re getting balanced meals and the nutrients your nails need to stay healthy. Shoot for about six ounces a day to prevent soft, weak nails. ■
