Energy and protein supplementation was most often associated with weight gain of women, and often targeted pregnant women with suboptimal weight. For pregnant women, energy and protein supplementation modestly increased maternal weight (86–90). Other maternal outcomes were not frequently reported, and were often secondary objectives of protein-energy supplementation interventions (33, 88). Many studies reported on infant health outcomes, including reductions in low birth weight and preterm births (19, 89–91). Adequate energy and protein intake was also relevant for interventions targeting the prevention of excessive gestational weight gain of overweight and obese pregnant women. These interventions restricted dietary energy intake of overweight women during pregnancy and resulted in reduced excess weight gain during pregnancy but had no impact on pregnancy-related hypertension and pre-eclampsia (19, 88).

Studies link high sodium intake to higher blood pressure, and evidence suggests that many people at risk for high blood pressure can reduce their risk by consuming less salt or sodium, as well as following a healthy diet. Most Americans consume more sodium than they need. The recommended amount is less than 2,300 mg per day for children and adults to age 50. The limit drops to 1,500 mg per day for those 51 and older or those of any age who are African American or have hypertension, diabetes or chronic kidney disease. You get 2,300 mg in just one teaspoon of salt. One good way to reduce your sodium intake is to eat fewer prepared and packaged foods.
Among other things, you need calcium to build healthy bones and teeth, keep them strong as you age, regulate the heart’s rhythm, and ensure your nervous system functions properly. Calcium deficiency can lead to, or exacerbate, mood problems such as irritability, anxiety, depression, and sleep difficulties. If you don’t get enough calcium in your diet, your body will take calcium from your bones to ensure normal cell function, which can lead to weakened bones or osteoporosis. Women are at a greater risk than men of developing osteoporosis, so it’s important to get plenty of calcium, in combination with magnesium and vitamin D, to support your bone health.
