Eating vegetables prevent disease

Vegetables rich in color generally indicate that they are higher in vital nutrients than their pale counterparts. 

Hundreds of studies from around the world have established that diet in vegetables appears to reduce the risk of a number of diseases. It’s including heart disease and other chronic health problems.

The disease preventing effects of plant foods are partly due to antioxidant affect, specific to the photochemicals along with vitamins, minerals and enzymes in vegetables protecting cells against damage from oxidation and strengthen immune activities. It would reduce risk of heart disease, cancer and other disease. 

There are twelve vegetables known as the cruciferous vegetables are particularly powerful protectors against top three killers in the USA – cancer, heart disease and strokes.

The twelve are broccoli, Brussels sprouts, cabbage, cauliflower, collards, kale, kohlrabi, mustard greens, horseradish, rutabaga turnips and watercress.

Researchers also found that eating beat-carotene rich vegetable did protect against lung cancer. The more variety vegetables people ate, the less likely they were to develop lung cancer.

Vegetable consumption can prevent disease

Vegetables are important components of a healthy diet. Vegetables are protective foods as their consumption prevents many diseases. Researches suggests that vegetable could help prevent major diseases such as cardiovascular diseases and certain cancers principally of the digestive system.

It also has been known that populations with high vegetables consumption have reduced risks of cancer. Harvard University researchers found that eating five servings per day of vegetables (particular broccoli, bok choy, cauliflower and brussels sprout) is associated with a 30 percent lower risk of ischemic strokes.

In addition to obesity, heart diseases, high blood pressure and cancer, vegetable may help prevent diabetes, osteoporosis, diverticular disease and gallstones.

There are several mechanism by which these protective effects may be mediated, involving antioxidants and other micronutrients. Vegetables are rich and comparatively cheap sources of vitamin like beta-carotene, vitamin B, folic acid, vitamin C, vitamin E also mineral like from, calcium, magnesium, phosphorus and dietary fiber.

The nutritional value of leafy vegetable will improve physical and mental wellbeing and prevent the onset of diseases.

Approach to diet and nutritional related diseases

Approach to diet and nutritional related diseases
The root causes of malnutrition include poverty and inequity. Eliminating these causes requires political and social action of which nutritional programmes can be only one aspect.

Sufficient, safe and varied food supplies not only prevent malnutrition but also reduce the risk of chronic disease.

It is well known that nutritional deficiency increases the risk of common infections disease, notably those of childhood, and vice versa.

There is, therefore, complimentary in terms of public and programmes designed to prevent chronic diseases and those designed to prevent other diet related and nutrition related diseases.

The double burden of disease is most effectively lifted by a range of integrated policies and programmes.

Such am integrated approach is the key action in countries where modest public health budgets will inevitably remain mostly devoted to prevention of deficiency and infection.

Indeed, there is no country, however, privileged, in which combating deficiency and infection are no longer public health priorities.

High incomes countries accustomed to programmes designed to prevent chronic diseases can amplify the effectiveness of the programmes by applying them to the prevention of nutritional deficiency and food related infectious disease.

The Obesity Battle

The Obesity Battle
Americans have more choices when it comes to food than anyone else on the planet.

While we are constantly seduced by hot fudge sundaes, double cheeseburgers, stuffed-crust pizza and deep-fried doughnuts, we are expected to be as lean as the models that grace the covers of fashion magazines.

How many people have the willpower to resist temptation time and time again?

A small minority, it would seem. In 2005, approximately two thirds of the Americans adult population was classified as overweight or obese, with about one third fitting into the overweight category and the other third being obese.

The harsh reality is that fewer than one third of Americans have healthy body weights.

Overweight and obesity come with a hefty price tag - $100 billion a year in medical bills and more than 400,000 premature deaths each year.

Excess body fat causes unwanted changes to the basic functioning of the human body, adversely affecting blood pressure, cholesterol, triglycerides, respiration, fertility, skin and joint health, hormones and insulin action.

Such changes significantly increase the risk for debilitating and often fatal health conditions, including the following:

• Cancer
• Gallbladder disease
• Gout
• Heart disease and stroke
• Kidney disease
• Osteoarthritis
• Sleep apnea
• Type 2 diabetes

To add insult to injury, a recent report found that being obese affectively ages a person by 20 years (in terms of physical health).

That puts an obese 30 year old in the same risk group as a normal weight 50 year old for developing serious medical problems.

Benefits Associated with Nutrients from Seafood

Benefits Associated with Nutrients from Seafood
The high nutritional quality of seafood makes it an important component of a healthy diet.

While protein is an important macronutrient in the diet, most American already consumes enough and do not need to increase their intake.

Fats and oil are also part of a healthy diet, but the type and amount of fat can be important - for example, with regard to cardiovascular disease.

Many Americans consume greater than recommended amounts of saturated fat as well as cholesterol from high-fat protein foods such as beef and pork.

Many seafood selections are lower in total and saturated fats and cholesterol than some more frequently selected anima protein foods such as fatty cuts of beef, pork and poultry and are equivalent in amount of fat to some leaner cuts of meat.

Since it is lower in saturated fats however by substituting seafood more often for other animal foods, consumers can decrease their overall intake of both total and saturated fats while retaining the nutritional quality of their protein food choices.

Seafood is also a primary source of EPA and DHA in the American diet.

The contribution of the nutrients to improving health and reducing risk for certain chronic disease in adult has not been completely elucidated.

There is evidence however, to suggest there are benefits to the developing infants such as increasing length of gestation, improved visual acuity and improve cognitive development.

In addition, there is evidence to support an overall benefit to the general population for reduced risk of heart disease among those who eat seafood compared to those who do not, and there may be benefits from consuming EPA and DHA for adults at risk for coronary heart disease.

Nutrition and Diet

Nutrition and Diet
Food is not simply a physiological fuel. It is a social phenomenon. In between we eat on average three meals a day and are subjected to a great deal of pressure on what we should eat, from manufacturer and advertisers, from experts and quacks and from custom and habit. Nutrition is a topic of conversation on which the average person can hold an opinion much as he holds opinions on nuclear weapon, the environment or taxation. Yet nutrition is unique among such controversies because the attendant opinion can be acted on at the individual level. A resident of Europe or North America cannot escape the threat of nuclear warfare, environment decay and certainly taxation. But they can change their diet any way they please without seeking permission, either by making an informed decision based on a sound understanding of nutrition, or by whim.

Nutrition controversies are not new. The Greek philosophers linked the four elements of cosmos – air, fire, water and earth – with four humors of man – blood, bile, phlegm, and black bile. Individual foods were assigned to humors. Accordingly, Hippocrates recommended pepper combined with honey and vinegar, for the treatment of feminine disorders. The ancient Chinese also held diet high in their medical kit-bag.

The old Chinese expert said: Experts at curing disease are inferior to those who warn against disease. Experts in the use of medicines are inferior to those who recommended a proper diet. The Egyptians believed the gut to be the root of all illness and sought considerable relief from the usage of figs.

Such early views on diet were theoretically arrived at by careful, logical thought. The first experimental evidence linking diet and disease was the relation between the incidence of scurvy aboard sailing ships and the lack of fresh fruit and vegetables. In the ensuing centuries, scientist employed the present day approach of experimentation to understand digestion, salivation, respiratory metabolism and the biological need for certain nutrients such as minerals, vitamins, amino acids and essential fatty acids. This quest extended well into the present century.

The Importance of Adequate Fiber Intake

The Importance of Adequate Fiber Intake
The importance of adequate intake of fiber to the improvement of health is demonstrated by some of the physiologic effects exerted by its various components. Particularly noteworthy are the hypoglycemic and hypolipidemic effect of soluble fiber. Slowing the absorption rate of carbohydrate can be very helpful to the diabetic in regulating blood glucose levels and lowering serum cholesterol levels presently appears to have significant benefit in the prevention of atherosclerosis.

Wheat 

Adequate fiber intake has been implicated in control of various gastrointestinal disorders, including diverticular disease, gallstones, irritable-bowel syndrome, inflammatory bowel disease, and constipation. It was suggested that fiber, especially wheat bran, is effective in the treatment of constipation; but evidence for the effectiveness of fiber in control of the other diseases seems equivocal. Nevertheless, populations with high fiber intakes have a lower incidence of these gastrointestinal disorders.

A generous fiber intake appears to be beneficial to some individual in their efforts at weight control. The bulk provided by fiber may have some satiety value, so that high fiber foods possibly reduce the hunger pangs associated with caloric restriction while simultaneously somewhat reducing nutrient utilization. The anti-toxic effect of fiber is a physiologic role often overlooked. Results of studies on experimental animals, particularly growing rats, have shows the protective effects of selected fiber supplements against a variety of toxic agents.
