Why proper nutrition is especially important in promoting optimal health for pregnant women, mothers ,babies, and young children

Well being healthy is important in general. for pregnant women it is importtant not to give into the cravings that are unhealthy. for mothers it depends on the situation and if there are any health problems(well that matters for all people) newborn babies should stay to milk and when they are about 12-18 months you should try spoon feeding them, no solids unless they have teeth, young children should get into the habit of healthy eating or else they wont be able to just stop eating junk food their whole life! since i am a child i an still getting into the habit of healthy eating, its much harder when you go your whole life eating what ever you wanted then you get diagnosed with Hypothyroidism or another health issue and your whole life changes. 

Muscles in the body us with a lot of things for example, if i wanted to lift a heavy box and had no muscle i would just collapse where i was because of the fact muscles hold us together. overall they are 650 muscle in the human body, all of them have different purposes and ways to keep us together. there are three types of muscle in the body skeletal, smooth, and cardiac muscle. skeletal muscle are attached to the bone and with movement. smooth muscle, this is found in the wall of our organs, such as our stomach, this muscle with movement   as well, without this muscle, we would only be allowed to eat small amounts. the cardiac muscle is the heart muscle and probably the most important one. these are only found in the walls of the heart and the heart pump blood to the other parts of your body. we have two different types of muscle fibers, slow twitch and fast twitch. slow twitch muscles enable long-endurance feats such as distance running. fast twitch fatigue faster but are used in powerful bursts of movements like sprinting. there are three different types of muscle contractions concentric, eccentric, isometric. concentric contraction causes muscles to shorten, thereby generating force.   eccentric contractions cause muscles to elongate in response to a greater opposing force. isometric contractions generate force without changing the length of the muscle.: //athleticquickness.com/muscle-contraction-types-part-1/
