The Shocking Link Between Your Liver and Your Feet: 12 Things Your Feet Can Tell YouCalorie intake and nutrient deficiencies -
Here are nutrients that are most likely to be deficient. Vitamin D. Vitamin D deficiency is especially common as we get older, since few foods are naturally rich in it. Getting enough sunlight for our skin to convert to vitamin D may be easier in the summer months, but we need to balance that benefit against skin cancer concerns.
Signs of deficiency include fatigue, bone pain, mood changes, muscle aches, and weakness. Foods high in vitamin D include fortified cow's milk and cereals, soy milk, mushrooms, canned tuna, shrimp, and salmon. Daily recommended intake is IU for adults up to age 70 and IU for those 71 and older; a daily 1,IU vitamin D supplement provides ample coverage.
Red blood cells, which carry oxygen throughout the body, rely on adequate iron stores. But pregnancy or heavy menstrual periods can take a toll, potentially leaving us lacking. So can increasingly popular plant-based diets, since animal products provide higher amounts of iron, and our bodies absorb iron more easily from animal sources.
If you're low on iron, you may feel cold, tired, or short of breath. You may have headaches more frequently. Meat and seafood typically offer plenty of iron, and plant-based sources include beans, lentils, grains, spinach, and fortified cereals. Women over 50 need 8 milligrams mg of iron per day; younger women, 18 mg daily.
Vitamin B B 12 is crucial to healthy nerve signaling and red blood cell production, but we get progressively less efficient at absorbing it as we age. Vegans and vegetarians are also at higher risk of deficiency, since plants don't contain the vitamin.
Signs of a B 12 shortfall include fatigue from anemia; numbness in hands, legs, and feet; or trouble with balance and walking. Memory can also suffer. Vitamin B 12 is readily found in fish, chicken, milk, and yogurt. If you prefer plant-based options, try fortified nondairy milks and cereals.
Adults need 2. Most of us know that calcium keeps bones strong; it also helps control muscle and nerve function and regulate our heartbeat. As estrogen drops, our ability to absorb calcium diminishes, and those on vegan diets can compound the risk by avoiding dairy products.
Calcium-rich foods include cow's milk, fortified soy or almond milks, yogurt, cheese, fortified cereals, and dark green vegetables like kale and broccoli. Most adults need 1, mg each day, but women over 50 need 1, mg. Don't count on symptoms — or their absence — to clue you in to a possible nutritional deficit.
Most deficiencies are subtle, with few glaring signs, Blake says. And it's not something you can diagnose on your own. That requires medical testing. Additionally, our bodies store small amounts of extra vitamins and minerals that would tide us over several weeks of poor eating, meaning our levels would have to be extremely low before a problem even shows up.
A vitamin D deficiency, for instance, might only announce itself in a broken bone. Calcium levels can't be accurately gauged from a blood test, Fung says. Typically, however, blood tests can reveal whether you're lacking in key nutrients, including vitamin D, iron, or B While there's "no need to test for every deficiency under the sun," Fung advises asking your doctor if she feels your risk factors warrant a closer look.
More than 24 million Americans cope with autoimmune disorders such as rheumatoid arthritis, psoriasis, or thyroid disease. But so far, scientists haven't identified potential ways to prevent these burdensome conditions, which disproportionately affect women.
Now, however, a Harvard study suggests that vitamin D and fish oil supplements may offer adults over 50 protection against developing autoimmune disorders. They only pose a health risk when people consume more than the recommended amount.

In fact, National Health and Nutrition Examination Surveys NHANES that assess the nutritional and health status of a nationally representative sample of the civilian, non-institutionalized US population have reported a high prevalence of select micronutrient inadequacies in the US population see Tables Nutritional assessments in populations are typically done by measuring nutrient intake through dietary surveys and comparing mean intake with the age- and gender-specific nutrient requirements. Although more difficult and costly to do in entire populations, nutritional biomarkers — biochemical indicators that give more objective and reliable measures of dietary exposure and nutrient body status — are sometimes also employed 6, 7.

We therefore evaluated the dietary micronutrient intake in obese individuals compared to a reference population and DRI recommendations. Furthermore, we determined the micronutrient status in obese subjects undergoing a standardized DRI-covering low-calorie formula diet to analyze if the DRI meet the micronutrient requirements of obese individuals.
