15 health benefits of eating apples
Many of us forget that sometimes, the simplest answers are the best. Better health could be as easy as reaching for the fruit bowl for some apples next time you need a snack
In 2004, USDA scientists investigated over 100 foods to measure their antioxidant concentration per serving size.Two apples—Red Delicious and Granny Smith—ranked 12th and 13th respectively. Antioxidants are disease-fighting compounds. Scientists believe these compounds help prevent and repair oxidation damage that happens during normal cell activity. Apples are also full of a fibre called pectin—a medium-sized apple contains about 4 grams of fibre. Pectin is classed as a soluble, fermentable and viscous fibre, a combination that gives it a huge list of health benefits.
1. Get whiter, healthier teeth
An apple won’t replace your toothbrush, but biting and chewing an apple stimulates the production of saliva in your mouth, reducing tooth decay by lowering the levels of bacteria.
2. Avoid Alzheimer’s
A new study performed on mice shows that drinking apple juice could keep Alzheimer’s away and fight the effects of aging on the brain. Mice in the study that were fed an apple-enhanced diet showed higher levels of the neurotransmitter acetylcholine and did better in maze tests than those on a regular diet.
3. Protect against Parkinson’s
Research has shown that people who eat fruits and other high-fibre foods gain a certain amount of protection against Parkinson’s, a disease characterized by a breakdown of the brain’s dopamine-producing nerve cells. Scientists have linked this to the free radical-fighting power of the antioxidants contained therein.
4. Curb all sorts of cancers
Scientists from the American Association for Cancer Research, among others, agree that the consumption of flavonol-rich apples could help reduce your risk of developing pancreatic cancer by up to 23 per cent. Researchers at Cornell University have identified several compounds—triterpenoids—in apple peel that have potent anti-growth activities against cancer cells in the liver, colon and breast. Their earlier research found that extracts from whole apples can reduce the number and size of mammary tumours in rats. Meanwhile, the National Cancer Institute in the U.S. has recommended a high fibre intake to reduce the risk of colorectal cancer.
5. Decrease your risk of diabetes
Women who eat at least one apple a day are 28 percent less likely to develop type 2 diabetes than those who don’t eat apples. Apples are loaded with soluble fibre, the key to blunting blood sugar swings.
6. Reduce cholesterol
The soluble fibre found in apples binds with fats in the intestine, which translates intolower cholesterol levels and a healthier you.
7. Get a healthier heart
An extensive body of research has linked high soluble fibre intake with a slower buildup of cholesterol-rich plaque in your arteries. The phenolic compound found in apple skins also prevents the cholesterol that gets into your system from solidifying on your artery walls. When plaque builds inside your arteries, it reduces blood flow to your heart, leading to coronary artery disease.
8. Prevent gallstones
Gallstones form when there’s too much cholesterol in your bile for it to remain as a liquid, so it solidifies. They are particularly prevalent in the obese. To prevent gallstones, doctors recommend a diet high in fibre to help you control your weight and cholesterol levels.
9. Beat diarrhea and constipation
Whether you can’t go to the bathroom or you just can’t stop, fibre found in apples can help. Fibre can either pull water out of your colon to keep things moving along when you’re backed up, or absorb excess water from your stool to slow your bowels down.
10. Neutralize irritable bowel syndrome
Irritable bowel syndrome is characterized by constipation, diarrhea, and abdominal pain and bloating. To control these symptoms doctors recommend staying away from dairy and fatty foods while including a high intake of fibre in your diet.
11. Avert hemorrhoids
Hemorrhoids are a swollen vein in the anal canal and while not life threatening, these veins can be very painful. They are caused by too much pressure in the pelvic and rectal areas. Part and parcel with controlling constipation, fibre can prevent you from straining too much when going to the bathroom and thereby help alleviate hemorrhoids.
12. Control your weight
Many health problems are associated with being overweight, among them heart disease, stroke, high blood pressure, type 2 diabetes and sleep apnea. To manage your weight and improve your overall health, doctors recommend a diet rich in fibre. Foods high in fibre will fill you up without costing you too many calories.
13. Detoxify your liver
We’re constantly consuming toxins, whether it is from drinks or food, and your liver is responsible for clearing these toxins out of your body. Many doctors are skeptical of fad detox diets, saying they have the potential to do more harm than good. Luckily, one of the best—and easiest—things you can eat to help detoxify your liver is fruits—like apples.
14. Boost your immune system
Red apples contain an antioxidant called quercetin. Recent studies have found thatquercetin can help boost and fortify your immune system, especially when you're stressed out.
15. Prevent cataracts
Though past studies have been divided on the issue, recent long-term studies suggest that people who have a diet rich in fruits that contain antioxidants—like apples—are 10 to 15 per cent less likely to develop cataracts.

The event of fertilization is sometimes used as a mark of the initiation of pregnancy, with the derived age being termedfertilization age, and is an alternative to gestational age. Fertilization usually occurs about two weeks before her nextexpected menstrual period, and if either date is unknown in an individual case it is a frequent practice to add 14 days to the fertilization age to get the gestational age and vice versa.The most commonly used event to mark the initiation of pregnancy is the first day of the woman's last normal menstrual period, and the resulting fetal age is called thegestational age. This choice is a result of a lack of a convenient way to discern the point in time when the actual creation of the baby naturally happens. In case of in vitro fertilisation, gestational age is calculated by days from oocyte retrieval + 14 days.
Development of embryo and fetus
The development of the mass of cells that will become the infant is called embryogenesis during the first approximately 10 weeks of gestation. During this time, cells begin to differentiate into the various body systems. The basic outlines of the organ, body, and nervous systems are established. By the end of the embryonic stage, the beginnings of features such as fingers, eyes, mouth, and ears become visible. Also during this time, there is development of structures important to the support of the embryo, including the placenta and umbilical cord. The placentaconnects the developing embryo to the uterine wall to allow nutrient uptake, waste elimination, and gas exchange via the mother's blood supply. The umbilical cord is the connecting cord from the embryo or fetus to the placenta.The sperm and the egg cell, which has been released from one of the female's twoovaries, unite in one of the two fallopian tubes. The fertilized egg, known as azygote, then moves toward the uterus, a journey that can take up to a week to complete. Cell division begins approximately 24 to 36 hours after the male and female cells unite. Cell division continues at a rapid rate and the cells then develop into what is known as a blastocyst. The blastocyst arrives at the uterus and attaches to the uterine wall, a process known as implantation.
After about 10 weeks of gestational age, the embryo becomes known as a fetus instead. At the beginning of the fetal stage, the risk of miscarriage decreases sharply, When the fetal stage commences, a fetus is typically about 30 mm (1.2 inches) in length, and the heart can be seen beating via ultrasound; the fetus can be seen making various involuntary motions at this stage. During continued fetal development, the early body systems and structures that were established in the embryonic stage continue to develop. Sex organs begin to appear during the third month of gestation. The fetus continues to grow in both weight and length, although the majority of the physical growth occurs in the last weeks of pregnancy.
Electrical brain activity is first detected between the 5th and 6th week of gestation, though this is still considered primitive neural activity rather than the beginning of conscious thought, something that develops much later in fetation. Synapses begin forming at 17 weeks, and at about week 28 begin to multiply at a rapid pace which continues until 3 to 4 months after birth.
Second trimesterMinute ventilation is increased by 40% in the first trimester. The womb will grow to the size of a lemon by eight weeks. Many symptoms and discomforts of pregnancy like nausea and tender breasts appear in the first trimester.
Although the fetus begins to move and takes a recognizable human shape during the first trimester, it is not until the second trimester that movement of the fetus, often referred to as "quickening", can be felt. This typically happens in the fourth month, more specifically in the 20th to 21st week, or by the 19th week if the woman has been pregnant before. It is common for some women not to feel the fetus move until much later. During the second trimester, most women begin to wear maternity clothes.Weeks 13 to 28 of the pregnancy are called the second trimester. Most women feel more energized in this period, and begin to put on weight as the symptoms of morning sickness subside and eventually fade away. The uterus, the muscular organ that holds the developing fetus, can expand up to 20 times its normal size during pregnancy.
Head engagement, where the fetal head descends into cephalic presentation, relieves pressure on the upper abdomen with renewed ease in breathing. It also severely reduces bladder capacity, and increases pressure on the pelvic floor and the rectum.Final weight gain takes place, which is the most weight gain throughout the pregnancy. The woman's abdomen will transform in shape as it drops due to the fetus turning in a downward position ready for birth. During the second trimester, the woman's abdomen would have been very upright, whereas in the third trimester it will drop down quite low, and the woman will be able to lift her abdomen up and down. The fetus begins to move regularly, and is felt by the woman. Fetal movement can become quite strong and be disruptive to the woman. The woman's navel will sometimes become convex, "popping" out, due to her expandingabdomen.
It is also during the third trimester that maternal activity and sleep positions may affect fetal development due to restricted blood flow. For instance, the enlarged uterus may impede blood flow by compressing the lower pressured vena cava, with the left lateral positions appearing to providing better oxygenation to the infant.
Determining gestational age
Since these are spread over a significant period of time, the duration of pregnancy necessarily depends on the date selected as the starting point chosen.
As measured on a reference group of women with a menstrual cycle of exactly 28-days prior to pregnancy, and who had spontaneous onset of labor, the mean pregnancy length has been estimated to be 283.4 days of gestational age as timed from the first day of the last menstrual period as recalled by the mother, and 280.6 days when the gestational age was retrospectively estimated by obstetric ultrasoundmeasurement of the fetal biparietal diameter (BPD) in the second trimester. Other algorithms take into account a variety of other variables, such as whether this is the first or subsequent child (i.e., pregnant woman is a primipara or a multipara, respectively), the mother's race, parental age, length of menstrual cycle, and menstrual regularity), but these are rarely used by healthcare professionals. In order to have a standard reference point, the normal pregnancy duration is generally assumed to be 280 days (or 40 weeks) of gestational age.
The best method of determining gestational age is ultrasound during the first trimester of pregnancy. This is typically accurate within seven days. This means that fewer than 5 percent of births occur on the day of being 40 weeks of gestational age; 50 percent of births are within a week of this duration, and about 80 percent are within 2 weeks. For the estimation of due date, mobile apps essentially always give consistent estimations compared to each other and correct for leap year, while pregnancy wheels made of paper can differ from each other by 7 days and generally do not correct for leap year.
The most common system used among healthcare professionals is Naegele's rule, which was developed in the early 19th century. This calculates the expected due date from the first day of the last normal menstrual period (LMP or LNMP) regardless of factors known to make this inaccurate, such as a shorter or longer menstrual cycle length. Pregnancy most commonly lasts for 40 weeks according to this LNMP-based method, assuming that the woman has a predictable menstrual cycle length of close to 28 days and conceives on the 14th day of that cycle.
As measured from the day of ovulation, the average time to birth has been estimated to be 268 days (38 weeks and two days), with a coefficient of variation of 3.7%.
Accurate dating of pregnancy is important, because it is used in calculating the results of various prenatal tests, (for example, in the triple test). A decision may be made to induce labour if a fetus is perceived to be overdue. Furthermore, if LMP and ultrasound dating predict different respective due dates, with the latter being later, this might signify slowed fetal growth and therefore require closer review.
The stage of pregnancy defined as the beginning of legal fetal viability varies around the world. It sometimes incorporates weight as well as gestational age.It ranges from 16 weeks in Norway, to 20 weeks in the US and Australia, 24 weeks in the UK and 26 weeks in Italy and Spain.
A balanced, nutritious diet is an important aspect of a healthy pregnancy. Eating a healthy diet, balancing carbohydrates, fat, and proteins, and eating a variety of fruits and vegetables, usually ensures good nutrition. Those whose diets are affected by health issues, religious requirements, or ethical beliefs may choose to consult a health professional for specific advice.
Drugs used during pregnancy can have temporary or permanent effects on the fetus. Therefore many physicians would prefer not to prescribe for pregnant women, the major concern being over teratogenicity of the drugs.
Drugs have been classified into categories A,B,C,D and X based on the Food and Drug Administration (FDA) rating system to provide therapeutic guidance based on potential benefits and fetal risks. Drugs, including some multivitamins, that have demonstrated no fetal risks after controlled studies in humans are classified as Category A. On the other hand drugs like thalidomide with proven fetal risks that outweigh all benefits are classified as Category

Coca is any of the four cultivated plants in the family Erythroxylaceae, native to western South America. The plant is a cash crop in Argentina, Bolivia, Colombia, and Peru. It also plays a role in many traditional Andean cultures as well as the Sierra Nevada de Santa Marta (see Traditional uses). Coca is known throughout the world for its psychoactive alkaloid, cocaine. The alkaloid content of coca leaves is low, between 0.25% and 0.77%.This means that chewing the leaves or drinkingcoca tea does not produce the intense high (euphoria, megalomania, depression) people experience with cocaine. Coca leaf extract had been used in Coca-Cola products from 1885, with cocaine being completely eliminated from the products in or around 1929. Extraction of cocaine from coca requires several solvents and a chemical process known as an acid/base extraction, which can fairly easily extract the alkaloids from the plant.
Traces of coca have been found inmummies dating 3000 years back. Other evidence dates the communal chewing of coca with lime 8000 years back. Extensive archaeological evidence for the chewing of coca leaves dates back at least to the 6th century AD Moche period, and the subsequent Inca period, based on mummies found with a supply of coca leaves, pottery depicting the characteristic cheek bulge of a coca chewer, spatulas for extracting alkali and figured bags for coca leaves and lime made from precious metals, and gold representations of coca in special gardens of the Inca in Cuzco.
Coca chewing may originally have been limited to the eastern Andes before its introduction to the Incas. As the plant was viewed as having a divine origin, its cultivation became subject to a state monopoly and its use restricted to nobles and a few favored classes (court orators, couriers, favored public workers, and the army) by the rule of the Topa Inca (1471–1493). As the Incan empire declined, the leaf became more widely available. After some deliberation, Philip II of Spain issued a decree recognizing the drug as essential to the well-being of the Andean Indians but urging missionaries to end its religious use. The Spanish are believed to have effectively encouraged use of coca by an increasing majority of the population to increase their labor output and tolerance for starvation, but it is not clear that this was planned deliberately.
In the early 20th century, the Dutch colony of Java became a leading exporter of coca leaf. By 1912 shipments to Amsterdam, where the leaves were processed into cocaine, reached 1 million kg, overtaking the Peruvian export market. Apart from the years of the First World War, Java remained a greater exporter of coca than Peru until the end of the 1920s.Other colonial powers also tried to grow coca (including the British in India), but with the exception of the Japanese in Formosa, these were relatively unsuccessful.
Traditional medical uses of coca are foremost as a stimulant to overcome fatigue, hunger, and thirst. It is considered particularly effective against altitude sickness.It also is used as an anesthetic and analgesic to alleviate the pain of headache,rheumatism, wounds and sores, etc. Before stronger anaesthetics were available, it also was used for broken bones, childbirth, and during trepanning operations on the skull. The high calcium content in coca explains why people used it for bone fractures. Because coca constricts blood vessels, it also serves to oppose bleeding, and coca seeds were used for nosebleeds. Indigenous use of coca has also been reported as a treatment for malaria, ulcers, asthma, to improve digestion, to guard against bowel laxity, as an aphrodisiac, and credited with improving longevity. Modern studies have supported a number of these medical applications.
What are the medical complications of cocaine?
Cocaine causes many adverse effects to many organ systems. Some complications are dependent on the route of exposure.

A reproductive system disease is any disease of the reproductive system.
Typesinfections that affect the reproductive tract, which is part of the Reproductive System. For females, reproductive tract infections can be in either the upper reproductive tract (fallopian tubes, ovary and uterus), and the lower reproductive tract (vagina, cervix and vulva); for males these infections are at the penis, testicles, urethra or the vas deferens. The three types of reproductive tract infections are endogenous infections, iatrogenic infections and the more commonly known sexually transmitted infections.Each has its own specific causes and symptoms, caused by a bacterium, virus, fungus or other organism. Some infections are easily treatable and can be cured, some are more difficult, and some are non curable such as AIDS and herpes.
Congenital abnormalitiesExamples of congenital abnormalities of the reproductive system include:
- Kallmann syndrome - Genetic disorder causing decreased functioning of the sex hormone-producing glands caused by a deficiency or both testes from the scrotum.
- Androgen insensitivity syndrome - A genetic disorder causing people who are genetically male (i.e. XY chromosome pair) to develop sexually as a female due to an inability to utilize androgen.
- Intersexuality - A person who has genitalia and/or other sexual traits which are not clearly male or female.
Examples of cancersExamples of cancers of the reproductive system include:
- Prostate cancer - Cancer of the prostate gland
- Breast cancer - Cancer of the mammary gland.
- Ovarian cancer - Cancer of the ovary.
- Penile cancer - Cancer of penis.
- Uterine cancer - Cancer of the uterus.
- Testicular cancer - Cancer of the testicle/(plural:testes).
- Cervical Cancer - Cancer of the cervix.
Examples of functional problemsExamples of functional problems of the reproductive system include:
- Impotence - The inability of a male to produce or maintain an erection.
- Hypogonadism - A lack of function of the gonads, in regards to either hormones or gamete production.
- Ectopic pregnancy - When a fertilized ovum is implanted in any tissue other than the uterine wall.
- Hypoactive sexual desire disorder - A low level of sexual desire and interest.
- Female sexual arousal disorder - A condition of decreased, insufficient, or absent lubrication in females during sexual activity
- Premature ejaculation - A lack of voluntary control over ejaculation.
- Dysmenorrhea - Is a medical condition of pain during menstruation that interferes with daily activities.
