We all have friends who only order salad no matter what else is available. Many think they are eating healthily. Protein should be both from plants as well as from non-plants – meat/fish. At least 10% of your daily calories, but not more than 35%, should come from protein (Institute of Medicine). The serious lack of protein in your diet has serious consequences. The results included a decrease in calcium absorption and a slight taking of calcium from bones. Consequences can take years to show up as fragile bones, weakness and poor mobility. Our bodies need calcium and protein in adequate balance.
The Institute of Medicine recommends adults daily get at least 7.2 grams of protein for every 20 pounds of body weight. In the US, the recommended daily allowance for those over 19 is 46 gr./day for women, and 56 gr./day for men. Elderly folks need more!
