Proving once and for all that people who work at NASA must be pretty brainy … scientists there have developed over 100 different meals for future manned trips to Mars. And each and every one of those meals is vegan! Maybe it’s time to rename Mars from the ‘Red Planet’ to the ‘Green Planet’?
The most healthful calcium sources are green leafy vegetables and legumes, or “greens and beans” for short. If you are looking for a very concentrated calcium source, calcium-fortified orange or apple juices contain 300 milligrams or more of calcium per cup in a highly absorbable form.
Dairy products do contain calcium, but it is accompanied by animal proteins, lactose sugar, animal growth factors, occasional drugs and contaminants, and a substantial amount of fat and cholesterol in all but the defatted versions.
Exercise is important for many reasons, including keeping bones strong. Active people tend to keep calcium in their bones, while sedentary people lose calcium.
Vitamin D controls your body’s use of calcium. About 15 minutes of sunlight on your skin each day normally produces all the vitamin D you need.
Sodium in the foods you eat can greatly increase calcium loss through the kidneys. If you reduce your sodium intake to one to two grams per day, you will hold onto calcium better.
Smokers lose calcium, too. A study of identical twins showed that, if one twin had been a long-term smoker and the other had not, the smoker had more than a 40 percent higher risk of a fracture.
