Omega-3 fatty acids reduce the risk of premature birth 0

A new Cochrane Review has found that increasing the intake of omega-3 long-chain polyunsaturated fatty acids (LCPUFA) during pregnancy reduces the risk of premature births.

Premature birth is the leading cause of death for children under 5 years old worldwide, accounting for close to one million deaths annually. Premature babies are at higher risk of a range of long-term conditions including visual impairment, developmental delay and learning difficulties.

“We know premature birth is a critical global health issue, with an estimated 15 million babies born too early each year,” explains Associate Professor Philippa Middleton from Cochrane Pregnancy and Childbirth and the South Australian Health and Medical Research Institute (SAHMRI). “While the length of most pregnancies is between 38 and 42 weeks, premature babies are those born before the 37-week mark — and the earlier a baby is born, the greater the risk of death or poor health.”

Associate Professor Middleton and a team of Cochrane researchers have been looking closely at long-chain omega-3 fats and their role in reducing the risk of premature births — particularly docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) found in fatty fish and fish oil supplements. They looked at 70 randomised trials and found that for pregnant women, increasing the daily intake of long-chain omega-3s:

  • lowers the risk of having a premature baby (less than 37 weeks) by 11% (from 134 per 1000 to 119 per 1000 births)
  • lowers the risk of having an early premature baby (less than 34 weeks) by 42% (from 46 per 1000 to 27 per 1000 births)
  • reduces the risk of having a small baby (less than 2500g) by 10%

“There are not many options for preventing premature birth, so these new findings are very important for pregnant women, babies and the health professionals who care for them,” Associate Professor Middleton says. “We don’t yet fully understand the causes of premature labour, so predicting and preventing early birth has always been a challenge. This is one of the reasons omega-3 supplementation in pregnancy is of such great interest to researchers around the world.”

The Cochrane review published today was first undertaken back in 2006, and concluded there wasn’t enough evidence to support the routine use of omega-3 fatty acid supplements during pregnancy. Over a decade on, this updated review concludes that there’s high quality evidence for omega-3 supplementation being an effective strategy for preventing preterm birth.

“Many pregnant women in the UK are already taking omega-3 supplements by personal choice rather than as a result of advice from health professionals,” says Associate Professor Middleton. “It’s worth noting though that many supplements currently on the market don’t contain the optimal dose or type of omega-3 for preventing premature birth. Our review found the optimum dose was a daily supplement containing between 500 and 1000 milligrams (mg) of long-chain omega-3 fats (containing at least 500mg of DHA) starting at 12 weeks of pregnancy.”

“Ultimately, we hope this review will make a real contribution to the evidence base we need to reduce premature births, which continue to be one of the most pressing and intractable maternal and child health problems in every country around the world.”

Adverse Health Effects of Plastics 0

In addition to creating safety problems during production, many chemical additives that give plastic products desirable performance properties also have negative environmental and human health effects. These effects include

  • Direct toxicity, as in the cases of lead, cadmium, and mercury
  • Carcinogens, as in the case of diethylhexyl phthalate (DEHP)
  • Endocrine disruption, which can lead to cancers, birth defects, immune system suppression and developmental problems in

Chemical Migration from Plastic Packaging into Contents

People are exposed to these chemicals not only during manufacturing, but also by using plastic packages, because some chemicals migrate from the plastic packaging to the foods they contain. Examples of plastics contaminating food have been reported with most plastic types, including Styrene from polystyrene, plasticizers from PVC, antioxidants from polyethylene, and Acetaldehyde from PET.

Among the factors controlling migration are the chemical structure of the migrants and the nature of the packaged food. In studies cited in Food Additives and Contaminants, LDPE, HDPE, and polypropylene bottles released measurable levels of BHT, Chimassorb 81, Irganox PS 800, Irganix 1076, and Irganox 1010 into their contents of vegetable oil and ethanol. Evidence was also found that acetaldehyde migrated out of PET and into water.

Recommendations

Find alternatives to plastic products whenever possible. Some specific suggestions:

  • Buy food in glass or metal containers; avoid polycarbonate drinking bottles with Bisphenol A
  • Avoid heating food in plastic containers, or storing fatty foods in plastic containers or plastic wrap.
  • Do not give young children plastic teethers or toys
  • Use natural fiber clothing, bedding and furniture
  • Avoid all PVC and Styrene products

Home Remedies for Hiccups 0

We have all been tormented by hiccups at some point in our lives those annoying, involuntary fits that can make it nearly impossible to carry on a conversation, eat a meal or even maintain a train of thought. Most people hiccup four to 60 times per minute during a bout of hiccups, and everyone has a specific, lifelong hiccup pattern.

The average hiccup spell can last from a few minutes to a few hours, but some people suffer from extended episodes that last days, months or even years. Hiccups that last longer than 48 hours are called persistent hiccups,and if they’ve lasted more than a month, you have intractable hiccups.

Both types can cause serious health problems and, in some cases, even death. For many of us, hiccups begin in the womb. The recapitulation theory proposes that fetuses use hiccups in respiration before their lungs are fully developed. This may help explain why premature infants spend up to 2.5 percent of their time hiccuping more than full-term babies.

Hiccup is an involuntary and sudden contraction of the muscles of the diaphragm. Normally, this action is repeated many times. A weird sound (hic) is produced. The sound is because of the epiglottis which closes when air suddenly tries to rush in. Hiccups are not as painful usually, though they can be very irritating at times. When they continue for a long period, they are very irritating.

Hiccups Causes:

  1. If you eat too fast, you can swallow air along with your food and end up
    with a case of the hiccups. Any other practices that might irritate the diaphragm such as eating too much (especially fatty foods) or drinking too much (drunk people hiccup) can make you prone to having hiccups.
  2. In these instances, your stomach, which sits underneath and adjacent to the
    diaphragm, is distended or stretched. Because they occur in relation to
    eating and drinking, hiccups are sometimes thought to be a reflex to protect
    you from choking.
  3. Sobbing or crying – Eating very spicy food,
  4. Consuming very hot food,
  5. Consuming excessive alcohol or soda,
  6. Coughing badly,
  7. Laughing badly.

Scientific Causes of Hiccups:

During normal breathing, we take in air from the mouth and nose, and it flows through the pharynx, past the glottis and into the larynx and trachea, ending in the lungs. The diaphragm, a large muscle between the chest and abdomen, aids this airflow. It moves down when we inhale, and then up when
we exhale. The phrenic nerves control the movement and sensation of the diaphragm. Any irritation to these nerves induces a spasm of the diaphragm. This spasm causes a person to take a short, quick breath that is then interrupted by the closing of the epiglottis (a flap that protects the glottis, the space between the vocal cords). The sudden closing creates the sound we all know as a hiccup.

So, hiccups are the result of diaphragm spasms. But what causes the irritation that leads to the spasm? There are only a few culprits for common hiccups, which usually disappear within a few minutes. One of the main irritants is a full stomach a result of swallowing too much food
or air. A distended stomach pushes against the phrenic nerves of the diaphragm, increasing the possibility of irritation and, therefore, hiccups. A full stomach of spicy food can do double damage hot foods can be especially irritating to those nerves. As any smoker on a bender can tell you, excess
smoking and drinking alcohol can also cause hiccups. A rapid temperature change outside or inside your stomach, from a cold night or a hot beverage, can be irritating enough to induce hiccups. Finally, emotions shock, excitement and stress — can also trigger a hiccup fit. Persistent and intractable hiccups can have more serious causes. There are hundreds, from hysteria to heart attacks, but most fit into one of five categories: central nervous system problems, metabolic problems, nerve irritation, anaesthesia or surgery, and mental health issues. Because these causes are so varied and potentially serious, anyone suffering from hiccups for more than 48 hours should head straight to a doctor.

Home Remedies for Hiccups:

  1. Holding your breath and counting to 10 is one way some people can get rid of their hiccups. Other people say that drinking from the “wrong” side of a glass of water is the way to become hiccup-free.
  2. Putting sugar under your tongue might work.
  3. Pound 5-6 green cardamom. Boil in 2 cups of water. When it boils down to 1
  4. cup remove, sieve and drink while warm.
  5. Drinking water frequently in short durations is also helpful.
  6. Eating a bowl full of yoghurt with a pinch of salt is also a good home remedy.
  7. Tickling the throat with the cotton swab is also helpful.
  8. Drink one ounce of white vinegar.
  9. Sucking crushed ice provides immediate relief
