That particular type of saturated fat, stearic acid, is relatively innocuous compared to the other common types of saturated fat. Helium is an inert, safe gas that is used to float balloons or sometimes to force foods out of pressurized containers. That's far less than the current average of 14 percent of calories. Chronic egg laying in pet cockatiels is described as laying more than 2 clutches of eggs per year. Most people should consume less salt be it regular or sea salt , because diets high in sodium increase blood pressure and the risk of heart attacks, strokes, and kidney disease.

Pineapples became known as an extravagant and exotic fruit, served only at the most lavish of banquets. However, pineapples are now common, and people are able to enjoy them in solid, dried, and juice forms. In Central and South America, pineapple is not only valued for its sweet taste, it has been used for centuries to treat digestion problems and inflammation. This article explores the health benefits and nutrition of pineapple, as well as providing ways to include it in the diet.
One cup of fresh pineapple chunks contains approximately:. As a percentage of your daily requirements, the same amount of fresh pineapple chunks provides:. Fresh pineapple is the only known source of an enzyme called bromelain, which might play a role in a range of different health benefits.
Eating fruits and vegetables of all types has long been associated with a reduced risk of many lifestyle-related health conditions. Many studies have suggested that increasing consumption of plant foods like pineapples decreases the risk of obesity , overall mortality, diabetes , and heart disease.
In one prospective study from , people who ate 3 or more servings per day of all fruits demonstrated a decreased risk and slowed progression of age-related macular degeneration. The risks of developing asthma are lower in people who consume a high amount of certain nutrients. One of these nutrients is beta-carotene.
It is found in orange, yellow and dark green plant foods, such as pineapple, mangoes , papaya , apricots, broccoli, cantaloupe, pumpkin , and carrots. Some smaller studies have suggested bromelain can also contribute to reducing asthma symptoms. Increasing potassium intake by consuming high potassium fruits and vegetables can help with lowering blood pressure. A high potassium intake is associated with a 20 percent decreased risk of dying from all causes. As an excellent source of vitamin C, a strong antioxidant, pineapples can help combat the formation of free radicals.
These are linked to the development of cancer. Older studies have shown beta-carotene to have an inverse association with the development of colon cancer in a Japanese population. A case-control study linked beta-carotene to a protective effect on prostate cancer. However, more recent studies have demonstrated that this may not be the case.
High fiber intake from all fruits and vegetables is associated with a lowered risk of colorectal cancer. Individuals with type 1 diabetes who consume high-fiber diets tend to have lower blood glucose levels , and individuals with type 2 diabetes may have improved blood sugar, lipids, and insulin levels. The Dietary Guidelines for Americans recommends 21 to 25 g per day for women and between 30 and 38 g per day for men. Pineapples, because of their fiber and water content, help to prevent constipation and promote regularity and a healthy digestive tract.
Pineapples are also rich in bromelain, an enzyme that helps the body digest proteins. Bromelain also reduces inflammatory immune cells, called cytokines, that damage the digestive tract lining.
The inedible stems are the most concentrated source of bromelain, which can be extracted and is readily available in supplement form. Antioxidant-rich diets have been shown to improve fertility. Because free radicals can damage the reproductive system, foods with high antioxidant activity like pineapples are recommended for those trying to conceive.
The antioxidants in pineapple, such as vitamin C and beta-carotene, and the vitamins and minerals copper , zinc, and folate have properties that affect both male and female fertility. Some studies have shown that bromelain, primarily in the stem, can reduce swelling, bruising, healing time, and pain associated with injury and surgical intervention. In one study, people who consumed 4, mg of potassium per day reduced the risk of death from ischemic heart disease 49 percent when compared with those who consumed less potassium.
Researchers link high potassium intakes to a reduced risk of stroke , protection against loss of muscle mass, preservation of bone mineral density, and reduction in the formation of kidney stones. The antioxidant vitamin C, when eaten in its natural form or applied topically, can help to fight skin damage caused by the sun and pollution, reduce wrinkles, and improve overall skin texture. Vitamin C also plays a vital role in the formation of collagen , the support system of the skin. Select a pineapple with a firm, plump body, without bruising, or soft spots and with green leaves at the crown.
A green outer shell does not mean the pineapple is not ripe and, contrary to popular belief, neither does the ease in which the leaves pull from the crown. Pick pineapples at their peak ripeness. Unlike other fruits, they will not continue to ripen once picked. Whole pineapples should be stored at room temperature, while cut pineapples should be stored in the refrigerator.
When eating canned or packaged pineapple, make sure to pick up the varieties canned in pineapple juice, not heavy syrup. There is an excellent selection of pineapple products available for purchase online , with thousands of customer reviews. Beta-blockers , a type of medication most commonly prescribed for heart disease, can cause potassium levels to increase in the blood.
High potassium foods should be consumed in moderation when taking beta-blockers. Consuming too much potassium can be harmful to people whose kidneys are not fully functional.
If your kidneys are unable to remove excess potassium from the blood, it could be fatal. Those with gastro-esophageal reflux disease GERD may experience an increase in symptoms, such as heartburn and regurgitation, when consuming highly acidic foods.
However, individual reactions vary. Focus on keeping the overall diet varied and adding a range of nutrients to the overall diet, rather than specific foods. A minimum of 5 servings of fruit and vegetables a day is recommended for overall health. Experts encourage more vegetables than fruits for weight management so this leaves room for about 2 servings a day of fruit. In order to obtain the nutritional benefits from a varied diet, eat no more than one serving or one cup of pineapple a day.

Journal of Asthma, 46 7 , The vast majority of the eggs within the ovaries steadily die, until they are depleted at menopause. At birth, there are approximately 1 million to 2 million eggs; by the time of puberty, only about , remain.
Of these, only about will be ovulated during a woman's reproductive lifetime. Any remaining eggs gradually die out at menopause. Continued The internal reproductive organs in the female include: The vagina is a canal that joins the cervix the lower part of uterus to the outside of the body.
It also is known as the birth canal. The uterus is a hollow, pear-shaped organ that is the home to a developing fetus. The uterus is divided into two parts: The corpus can easily expand to hold a developing baby. A channel through the cervix allows sperm to enter and menstrual blood to exit. The ovaries are small, oval-shaped glands that are located on either side of the uterus.
The ovaries produce eggs and hormones. These are narrow tubes that are attached to the upper part of the uterus and serve as tunnels for the ova egg cells to travel from the ovaries to the uterus. Conception , the fertilization of an egg by a sperm, normally occurs in the fallopian tubes.
The fertilized egg then moves to the uterus, where it implants into the lining of the uterine wall. What Happens During the Menstrual Cycle? During the follicular phase of the menstrual cycle, the following events occur: Two hormones, follicle stimulating hormone FSH and luteinizing hormone LH , are released from the brain and travel in the blood to the ovaries.
The hormones stimulate the growth of about 15 to 20 eggs in the ovaries, each in its own "shell," called a follicle. As estrogen levels rise, like a switch, it turns off the production of follicle-stimulating hormone. This careful balance of hormones allows the body to limit the number of follicles that mature. As the follicular phase progresses, one follicle in one ovary becomes dominant and continues to mature. This dominant follicle suppresses all of the other follicles in the group.
As a result, they stop growing and die. The dominant follicle continues to produce estrogen. Ovulatory Phase of the Menstrual Cycle The ovulatory phase, or ovulation , starts about 14 days after the follicular phase started. During this phase, the following events occur: The rise in estrogen from the dominant follicle triggers a surge in the amount of luteinizing hormone that is produced by the brain.
This causes the dominant follicle to release its egg from the ovary. As the egg is released a process called ovulation , it is captured by finger-like projections on the end of the fallopian tubes fimbriae.
