Do you hate cholesterol?

Please don't answer the question now because after read this article, you might change your believe about cholesterol. Some of hormones in our body are synthesized from cholesterol. When you are stress, the hypotahalamus, basically part of your brain will release corticotrophin releasing hormone(CRH) which it will stimulate the secretion of corticotropins hormone by adrenal pituitary.

Corticotropins hormone travel in our body via blood vessels until it reach at adrenal cortex( organs just above our kidneys). By react with the receptor sites at the adrenal cortex, it will stimulate the secretion of corticosteroids(synthesized from cholesterol) which is important in regulation of glucose,fat & protein metabolism. CRH usually produce during stress condition including when we are hungry.Hunger also considered physiologically as STRESS. So, you don't like cholesterol? Ok, fine. Corticosteroids won't be secrete, no glucose,fat or protein metabolism occurs. No energy will be provided for you.

Beside corticosteroids, gonadal hormones also have been synthesized from cholesterols. The example for gonadal hormones are estrogens. Estrogens have several metabolic effects including maintaining low total blood cholesterol levels and facilitating calcium uptake which helps sustain the density of skeleton. In other word, estrogen helps to get your bone stronger.So ladies, please do not get hysteria with cholesterol. This is the reason why do women after menapouse tend to get osteophoresis because there are no longer estrogens to help their bones.

As for men, testosterone(also synthesized from cholesterol) maintain the accessory organs include ducts,glands and the penis-causing them to grow and assume adult size and function. When the hormone is deficient or absent,all accessory organs atrophy, semen volumes declines markedly,erection and ejaculation are impaired. Thus, a man becomes both sterile and unable to carry out sexual intercourse.

The conclusion is don't worry too much about cholesterol. The most important thing is have a healthy diet and lifestyles-means beside eat and eat ...let's go for a jog, a walk,hiking, swimming or playing badminton 3 times in a week.
