Breast milk contains more than 700 bacteria

Breast milk contains more than 700 bacteria:

Microbes taken from breast milk by the infant are identified

Spanish researchers have traced the bacterial microbiota map in breast milk, which is the main source of nourishment for newborns. The study has revealed a larger microbial diversity than originally thought: more than 700 species.

The breast milk received from the mother is one of the factors determining how the bacterial flora will develop in the newborn baby. However, the composition and the biological role of these bacteria in infants remain unknown.

A group of Spanish scientists have now used a technique based on massive DNA sequencing to identify the set of bacteria contained within breast milk called microbiome. Thanks to their study, pre- and postnatal variables influencing the micriobial richness of milk can now be determined.

Colostrum is the first secretion of the mammary glands after giving birth. In some of the samples taken of this liquid, more than 700 species of these microorganisms were found, which is more than originally expected by experts. The results have been published in the 'American Journal of Clinical Nutrition'.

"This is one of the first studies to document such diversity using the pyrosequencing technique (a large scale DNA sequencing determination technique) on colostrum samples on the one hand, and breast milk on the other, the latter being collected after one and six months of breastfeeding," explain the coauthors, María Carmen Collado, researcher at the Institute of Agrochemistry and Food Technology (IATA-CSIC) and Alex Mira, researcher at the Higher Public Health Research Centre (CSISP-GVA).

The most common bacterial genera in the colostrum samples were Weissella, Leuconostoc, Staphylococcus, Streptococcus and Lactococcus. In the fluid developed between the first and sixth month of breastfeeding, bacteria typical of the oral cavity were observed, such as Veillonella, Leptotrichia and Prevotella.

Loquat fruit benefits

Delicious, loquats are very low in calories; provide just 47 cal per 100 g, however, rich in insoluble dietary fiber, pectin. Pectin retains moisture in the colon and thus functions as bulk laxative and by this way, it helps to protect the colon mucous membrane by decreasing exposure time to toxic substances as well as binding to cancer causing chemicals in the colon.
Pectin has also been shown to reduce blood cholesterol levels by decreasing its re-absorption in the colon by binding bile acids resulting in its excretion from the body.
Loquat fruit is an excellent source of vitamin-A (provides about 1528 IU per 100g), and phenolic flvonoid antioxidants such as chlorogenic acid, neo-chlorogenic acid, hydroxybenzoic acid, feruloylquinic acid, protocatechuic acid, epicatechin, coumaric acids and ferulic acid. Ripen fruits have more chlorogenic acid concentrations.
Vitamin A maintains integrity of mucus membranes and skin. Lab studies have shown that consumption of natural fruits rich in vitamin-A and flavonoids helps to protect from lung and oral cavity cancers.
Fresh fruit is very rich in potassium and some B-complex vitamins such as folates, vitamin B-6 and niacin and contain small amounts of vitamin-C. Potassium is an important component of cell and body fluids, helps controlling heart rate and blood pressure.
It is also a good source of iron, copper, calcium, manganese, and other minerals. Manganese is used by the body as a co-factor for the antioxidant enzyme, superoxide dismutase. Copper is required in the production of red blood cells. Iron is required for as a cofactor in cellular oxidation as well for red blood cell formation.

Medical Facts of Banana Fruit

Banana fruit is rich in calories, but very low in fats. The fruit contains good amounts of health benefiting anti-oxidants, minerals, and vitamins.

Banana pulp is composed of soft, easily digestible flesh with simple sugars like fructose and sucrose that when eaten replenishes energy and revitalizes the body instantly; thus, for these qualities, bananas are being used by athletes to get instant energy and as supplement food in the treatment plan for underweight children.

The fruit contains good amount of soluble dietary fiber (7% of DRA per 100 g) that helps normal bowel movements; thereby reducing constipation problems.

It contains many health promoting flavonoid poly-phenolic antioxidants such as lutein, zeaxanthin, beta and alpha carotenes in small amounts. These compounds help act as protective scavengers against oxygen-derived free radicals and reactive oxygen species (ROS) that play a role in aging and various disease processes.

It is also a very good source of vitamin-B6 (pyridoxine), provides about 28% of daily-recommended allowance. Pyridoxine is an important B-complex vitamin that has beneficial role in the treatment of neuritis, anemia, and decreasing homocystine (one of the causative factor for coronary artery disease (CHD) and stroke episodes) levels in the body.

The fruit is also good source of vitamin-C (about 8.7 mg per 100g). Consumption of foods rich in vitamin-C helps body develop resistance against infectious agents and scavenge harmful oxygen free radicals.

Fresh bananas provide adequate levels of minerals like copper, magnesium, and manganese. Magnesium is essential for bone strengthening and has cardiac-protective role as well. Manganese is used by the body as a co-factor for the antioxidant enzyme, superoxide dismutase. Copper is required in the production of red blood cells.

Fresh banana is a very rich source of potassium. 100 g fruit provides 358 mg potassium. Potassium is an important component of cell and body fluids that helps control heart rate and blood pressure, countering bad effects of sodium.

Medical facts of Kiwi Fruit

Kiwifruit is a very rich source of soluble dietary fiber (3.8 g per 100 g of fruit OR 10% of RDA), which makes it a good bulk laxative. The fiber content helps to protect the colon mucous membrane by decreasing exposure time to toxins as well as binding to cancer causing chemicals in the colon.

The fruit is an excellent source of antioxidant vitamin-C; provides about 154% of the DRI (daily-recommended intake). Consumption of foods rich in vitamin-C helps body develop resistance against infectious agents and scavenge harmful free radicals.

Kiwi fruit contains very good levels of vitamin-A, vitamin-E, vitamin-K and flavonoid anti-oxidants such as beta-carotene, lutein and xanthin. Vitamin K has potential role in the increase of bone mass by promoting osteotrophic activity in the bone. It also has established role in Alzheimer's disease patients by limiting neuronal damage in the brain.

Research studies have shown that certain substances in kiwi-fruit functions as blood thinner similar to aspirin; helps to prevent clot formation inside the blood vessels and protects from stroke and heart attacks.

Kiwi seeds are an excellent source of omega3 fatty acids. Research studies shows that consumption of foods rich in ω-3 fatty acids may reduce the risk of coronary heart disease, stroke, and help prevent development of ADHD, autism, and other developmental differences in children.

Fresh kiwi fruit is a very rich source of heart healthy electrolyte "potassium". Potassium is an important component of cell and body fluids that helps controlling heart rate and blood pressure by countering effects of sodium.

It also contains good amounts of minerals like manganese, iron and magnesium. Manganese is used in the body as a co-factor for the powerful antioxidant enzyme, superoxide dismutase. Magnesium is an important bone-strengthening mineral like calcium.

Medical Benefits of Apricots

Fresh fruits are low in calories, composing just 50 calories per 100 g. However, they are rich source of dietary fiber, antioxidants, vitamins, and minerals. The fruits are enriched with numerous health promoting phyto-chemicals; that helps prevent heart disease, reduce LDL, ("bad cholesterol") levels and offers protection against cancers.

Apricots are excellent sources of vitamin-A and carotenes. 100 g fresh fruits have 1926 IU or 64% of daily-required levels of vitamin A. Both of these compounds are known to have antioxidant properties and are essential for vision. Vitamin-A is also required for maintaining healthy mucus membranes and skin. Consumption of natural fruits rich in carotenes helps protect body from lung and oral cavity cancers.

Fresh fruits contain vitamin-C, another natural anti-oxidant. Vitamin-C helps body develop resistance against infectious agents and scavenge harmful oxygen free radicals.

They are also good source of minerals such as potassium, iron, zinc, calcium and manganese. Potassium is a heart-healthy mineral; an important component of cell and body fluids that help regulate heart rate and blood pressure.

The total anti-oxidant or ORAC value of raw apricots is 1115 umol TE/100 g. Much of this in these fruits comes from some important health promoting flavonoid poly phenolic anti-oxidants such as lutein, zeaxanthin and beta cryptoxanthins. Altogether these compounds act as protective scavengers against oxygen-derived free radicals and reactive oxygen species (ROS) that play a role in aging, cancers and various disease process.

Zeaxanthin, a carotenoid selectively absorbed into the retinal "macula lutea" in the eyes where it is thought to provide anti-oxidant and protective light-filtering functions. Thus, consumption of fruits like apricots rich in zeaxanthin helps eyes protect from age-related macular disease (AMRD), especially in the elderly people.in

Medical benefits of Apple

Delicious and crunchy apple is one of the popular fruit that contain an impressive list of essential nutrients, which are required for normal growth and development and overall nutritional well-being.

Apples are low in calories; 100 g of fresh fruit slices provide only 50 calories. The fruits are however, contain no saturated fats or cholesterol; but rich in dietary fiber, which helps, prevent absorption of dietary LDL cholesterol in the gut. The dietary fibers also help protect the mucous membrane of the colon from exposure to toxic substances by binding to cancer causing chemicals in the colon.

Apple fruit contains good quantities of vitamin-C and beta-carotene. Vitamin C is a powerful natural antioxidant. Consumption of foods rich in vitamin C helps body develop resistance against infectious agents and scavenge harmful, pro-inflammatory free radicals from the body.

Apples are rich in antioxidant phyto-nutrients flavonoids and polyphenols. The total measured anti-oxidant strength (ORAC value) of 100 g apple fruit is 5900 TE. The important flavonoids in apples are quercetin, epicatechin, and procyanidin B2. Apples are also good in tartaric acid that gives tart flavor to them. These compounds help body protect from deleterious effects of free radicals.

In addition, apple fruit is a good source of B-complex vitamins such as riboflavin, thiamin, and pyridoxine (vitamin B-6). Together these vitamins help as co-factors for enzymes in metabolism as well as in various synthetic functions inside the body.

Apple also contains small amount of minerals like potassium, phosphorus, and calcium. Potassium is an important component of cell and body fluids helps controlling heart rate and blood pressure; thus counters the bad influences of sodium.

Anorexia Nervosa

Anorexia nervosa is an eating disorder and, more importantly, a psychological disorder.
The cause of anorexia has not been definitively established, but self-esteem and body-image issues, societal pressures, and genetic factors likely each play a role.
Anorexia affects females far more often than males and is most common in adolescent females.
Anorexia tends to affect the middle and upper socioeconomic classes and Caucasians more often than less advantaged classes and ethnic minorities in the United States.
The disorder affects about 1% of adolescent girls and about 0.3% of males in the U.S.
People with anorexia tend to show compulsive behaviors, may become obsessed with food, and often show behaviors consistent with other addictions in their efforts to overly control their food intake and weight.
Men with anorexia are more likely to also have other psychological problems; affected women tend to be more perfectionistic and be more displeased with their bodies.
Children and adolescents with anorexia are at risk for a slowing of their growth and development.
The extreme dieting and weight loss of anorexia can lead to a potentially fatal degree of malnutrition.
Other possible complications of anorexia include heart-rhythm disturbances, digestive abnormalities, bone density loss, anemia, and hormonal and electrolyte imbalances.
Given the prevalence of denial of symptoms by individuals with anorexia, gathering information from loved ones of the anorexia sufferer is important in the diagnosis and treatment of the disorder.
Most medications are much better at treating symptoms that are associated with anorexia than addressing the specific symptoms of anorexia themselves.
The treatment of anorexia must focus on more than just weight gain and often involves a combination of individual, group, and family psychotherapies in addition to nutritional counseling.
The Maudsley model of family therapy, in which the family actively participates in helping their loved one achieve a more healthy weight, is considered the most effective method of family therapy for treating anorexia in adolescents.
The prognosis of anorexia is variable, with some people making a full recovery. Others experience a fluctuating pattern of weight gain followed by relapse or a progressively deteriorating course over many years.
Helping people understand the unrealistic and undesirable nature of media representations of excessive thinness as beautiful is one way to help prevent anorexia.
As with many other illnesses with addictive symptoms, it takes a day-to-day effort to control the urge to relapse, and treatment may be needed on a long-term basis.
Increased understanding of the causes and treatments for anorexia remain the focus of ongoing research in the effort to improve the outcomes of individuals with this disorder
