After 40 years, these elements must be monitored.

Magnesium. The lack of this electrolyte is a fairly common problem among older women. It can cause constipation, muscle spasms, headaches, and digestive dysfunction. Get tested to see if your diet is high enough in magnesium. It is found in foods such as beans, nuts, and leafy greens. Vitamin E. It is a fat-soluble vitamin that can protect your cells from oxidative damage and slow down the aging process. Add hazelnuts, sunflower seeds, peanuts, and corn oil to your diet. Iron. Women often lose iron as a result of heavy menstrual bleeding, which can occur for many reasons. Another problem is that as we age, less acid is produced in our stomach, which impairs iron absorption.
