By the time a child is 4-8 years old, his sugar consumption skyrockets to an average of 21 teaspoons a day. The same study found 14-18 year old children intake the most sugar on a daily basis, averaging about 34.3 teaspoons.
In space, the body begins to adapt to the microgravity environment. NSBRIâs science and technology program is addressing ways to reduce or eliminate many of the changes to the body that impact an astronautâs ability to perform well in space and that might impact their health after returning to Earth.
In space, the lack of gravity signals the osteoclasts to begin breaking down the unnecessary bone and the osteoblasts either don't change or slow their production of new bone. The net result is for a loss of bone mineral. Astronauts lose 1 to 2% of their bone mass for each month they are in space. This means that they lose 10% of their bone mass in less than a year â on Earth, humans lose 10% of their bone mass after the age of 50 and over a period of 10 years!
