According to WHO, 7.8% of pregnant women in Africa have night blindness and 15.3% have low serum retinol concentrations Vitamin A deficiency (VAD) during pregnancy is associated with increased maternal mortality [3] and increased infant mortality rates during the first year of life 

 1...  Is vitamin A safe during pregnancy?
Since a number of foods in the U.S. are fortified with preformed vitamin A, pregnant women should avoid multivitamin or prenatal supplements that contain more than 1,500 mcg (5,000 IU) of vitamin A. Vitamin A from beta-carotene is not known to increase the risk of birth defects.”

 2...  What birth defects are caused by vitamin A?
These birth defects can include malformations of the eye, skull, lungs, and heart . Women who might be pregnant should not take high doses of vitamin A supplements. Unlike preformed vitamin A, beta-carotene is not known to be teratogenic or lead to reproductive toxicity 

 3.... Is vitamin A needed during pregnancy?
Vitamin A is a fat-soluble vitamin that's stored in the liver. ... Vitamin A is particularly essential for women who are about to give birth because it helps with postpartum tissue repair. It also helps maintain normal vision, fights infections, supports your immune system, and helps with fat metabolism.

 4....  Vitamin A in Pregnancy
One of the hottest topics for pregnancy health is Vitamin A supplementation. Is it safe? How much is too much? Am I getting enough from my diet?
Before we get to the answers to these questions, it is very important to know that Vitamin A is an antioxidant that is essential for a healthy pregnancy. Vitamin A is one of many nutrients that plays a critical role in:
  • helping the body maintain homeostasis
  • prevention of anemia
  • supporting metabolism during pregnancy
  • tissue maintenance and development (cell growth) in pregnancy
  • fetal development, especially of the bones, teeth, skin, and vision
Tolerable upper intake levels (ULs) of preformed vitamin A in pregnancy and lactation (from foods and supplements) for women ages 19+ is 3,000 mcg RAE or 10,000 IU per day.
Vitamin A is available in the human diet in two forms. The first is preformed vitamin A, known as retinol and retinyl ester, that comes from animal foods – dairy products, meat and fish. The second is provitamin A carotenoids, the most common being beta-carotene (but also alpha-carotene and beta-cryptoxanthin) that comes from many orange, red and yellow fruits and vegetables, as well as a variety of dark green leafy vegetables.

Poor quality and too little sleep are common during pregnancy, when many women experience fragmented sleep and symptoms of insomnia. Even women who don’t generally experience sleep problems find that during pregnancy they have difficulty falling asleep and staying asleep, as well as trouble getting enough sleep. We talk a lot about sleep issues for new mothers. But new research   suggests we should be paying more attention to the sleep health of expectant mothers as well. Researchers at the University of Pittsburgh Medical Center found   links between both the quality and quantity of pregnant women’s sleep and complications at birth, including low birth weight ...

Fiber deficiency during Pregnancy...4 Brought to U.... http://successgain.us     and    http://successgain.info   7...  Why do we need to eat fibre? It used to be called “roughage”, and people tried to get rid of it.  Now we have heard plenty about it, but why do we need fibre in our diet? Dietary fibre is actually a form of  carbohydrate that does not get digested by enzymes in our small intestine, and so its sugar units are not absorbed into the bloodstream.  Dietary fibre is therefore known as ‘non-glyceami"‘. However, fibre has important effects on other nutrients within the small intestine and through effects on the large intestine, where few other nutrients arrive intact.  It has a range of valuable health effects: Smooths out digestion and absorption of glucose and fats in the small intestine.  It reduces the Glycaemic index of a meal. Provides fuel for the healthful or  good ba...

Know about Spinal cord Brought to U.... http://successgain.us     and    http://successgain.info My memories Know about Spinal cord Posted in 2015 The spinal cord is a long, fragile tubelike structure that begins at the end of the brain stem and continues down almost to the bottom of the spine (spinal column). The spinal cord consists of nerves that carry incoming and outgoing messages between the brain and the rest of the body. It is also the center for reflexes, such as the knee jerk reflex  Like the brain, the spinal cord is covered by three layers of tissue (meninges). The spinal cord and meninges are contained in the spinal canal, which runs through the center of the spine. In most adults, the spine is composed of 26 individual back bones (vertebrae). Just as the skull protects the brain, vertebrae protect the spinal cord. The vertebrae are separated by disks made of cartilage, which act as cushions, reducing the forces generated by...
