Nutrition and bone health throughout life

Thursday, January 7th, 2010

nutrition and bone health throughout lifeThe development and bone growth is a process that takes place from the womb to the last days of life of the individual. A lifetime for the bone can be enhanced or, conversely, to not reach their optimal development and will gradually weaken.

1. The diet is key throughout life

In this complex process, bone tissue has an array of nutritional requirements that will need to cover food through the individual ingest.

From this point of view, pharmacology or supplementation are unimportant because, if necessary, it will be only for short periods of time and of course, can never replace what food should be provided from birth of the individual or even before that.

It is known that properly organize food from early childhood brings great benefits in terms of health, including bone and quality of life. It is therefore necessary to always emphasize the importance of nutrition education.

2. Pregnancy and lactation

Pregnancy. It is a stage of life where it is recommended to increase the intake of calcium.
During pregnancy and lactation produced a series of physiological and environmental constraints make it necessary to bring food contributions and lifestyles of this special impact on mother and child.

The change in the nutritional needs and, in particular, changes in phospho-calcium balance was largely due to hormonal changes that serve as substrate for all the processes of synthesis and maternal-fetal adaptation that develop along pregnancy, fetal maturation and during lactation to feed the child, always with the priority needs of the fetus or infant.

As a result of the changes that take place before fetal skeletal mineralization is favored progressive retention of calcium to meet the increasingly growing demand for fetal skeletal mineralization. (more…)

Food for Bones

Wednesday, January 6th, 2010

food for bonesWhile everyone seems to know that it is necessary, very few people consume minimal amounts of calcium, hence, bone diseases are so common.

Statistics show that in Argentina between 40 and 50 per cent of teenagers of both sexes, and between 30 and 40 percent of those over 25 years consume less than 50 percent of the recommended calcium dose for age.

This calcium deficiency and its persistence throughout life, warning about a widespread nutritional problem, it is one of the agents responsible for the high incidence of osteoporosis in adulthood, and the frequency of fractures, says Dr. Maria Luz de Portela, Professor, Chair of Nutrition Faculty of Pharmacy and Biochemistry, UBA.

The recommended calcium intake for adults is 1000 milligrams a day. However, according to figures from the National Institute of Statistics and Censuses (INDEC) on the availability of foods that provide calcium in Argentina is less than 75 percent of the recommended per capita.

Nutritional studies showed that Argentines observe a high protein, low consumption of milk, and low fruit and vegetable. All this results in an inadequate intake of calcium and vitamin A. However, in comparison with previous work, in the last twenty years there was a gradual increase in calcium intake, a trend that manifested itself in increased sales of milk in the 90s, researchers say.

Bone Health Exercise and Nutrition

Sunday, December 27th, 2009

bone healthHave been tested that exercise at an early age by promoting games and sports from kindergarten, gives effects on bone mineral density are more stable and higher than in subjects who were not stimulated early.

The normal daily physical activity, not subject to specific programs is insufficient stimulus to improve bone mass. Definitely overload exercises allow significant improvements in both sexes and any age on BMD

Excessive physical activity and often highly competitive sport beyond the tolerances of bone stimulation causing negative effects on both physiology and structure of bone.

The effects of exercise on bone tissue are possible only when a food base is established. The effects of recommended intakes of calcium are enhanced by the addition of exercise. This effect is most evident in aged subjects and in women in perimenopausal period.

INTRODUCTION

Osteoporosis is a systemic disease characterized by low bone mass and architecture poor, both increase bone fragility leaving it susceptible to fracture.

One in three postmenopausal women in particular have advanced osteopenia francs osteporosis values. Interestingly, this decline in BMD was significantly correlated with levels of sarcopenia, ie loss of muscle tissue, which characterizes the sedentary elderly. This correlation is less significant in men and women of the same age but who remain physically active. Per year in Europe is recorded about 650,000 hip fractures, which cause a 20% mortality and 50% partial or complete disability.

Other variables or factors that may affect bone metabolism, bone would be the use of psychoactive drugs, loss of muscle strength. In rlacion to fractures, loss of stability and balance, and lost some senses like hearing and sight, predispose to falls and fractures.

In this article we will discuss the relationship between exercise and bone and try to give some idea about the intensity of exercise for optimizing exercise and diet for bone health. (1) (more…)

Your bones are forever

Thursday, December 17th, 2009

bone healthFrom childhood we are taught that we must take a glass of milk every day, because it contains lots of calcium for bones. Maintaining strong bones is not so simple. Physical exercise, especially strength, it is important to prevent osteoporosis. We propose a plan to make your bones as strong, which will dream to retire to risk sports with your grandchildren.

1. Osteoporosis, the great enemy
Sport. Exercise helps strengthen bones.  Not only women should worry about maintaining bone density. Although bone loss is identified as a problem that affects women after reaching menopause, in fact, osteopenia or bone loss affects both men and women. No difference between sexes, such as wrinkles.

After a certain age, our bones, joints, skin, hair, brain and other tissues deteriorate. The problem is that women are more likely to have osteoporosis when they reached the menopause by the lack of production of estrogen, and therefore, more socially conscious women to keep the bone that the bone men.

Men are also attacked by the quiet that is eating rodent bones, osteoporosis. From the 45 or 50 years, more men with symptoms of osteoporosis than prostate cancer.

But if both men and women look after the quality of bone from young, we reach the critical age with higher bone density than other people, and with stronger bones and stronger.
