Causes of diabetes

Certain factors that contribute to the development of diabetes are

Heredity

Heredity is a major factor. That diabetes can be inherited has been known for centuries. However, the pattern of inheritance is not fully understood. Statistic indicates that those with a family history of the disease have a higher risk of developing diabetes than those without such a background. The risk factor is 25 to 33 percent more.

One reason why diabetes, especially type-2 diabetes runs in the family is because of the diabetes gene. But even it is caused by genetic factors beyond your control; there is no reason to suffer from it. Diabetes mellitus cannot be cured in full sense of the term, but it can be effectively controlled so that you would not know the difference.

Diet

Diabetes has been described by most medical scientists as a prosperity’ disease, primarily caused by systematic overeating. Not only is eating too much sugar and refined carbohydrates harmful, but proteins and fats, which are transformed into sugar, may also result in diabetes if taken in excess.

It is interesting to note that diabetes is almost unknown in countries where people are poor and cannot afford to overeat.

The incidence of diabetes is directly linked with the consumption of processed foods rich in refined carbohydrates, like biscuits, bread, cakes chocolates, pudding and ice creams.

Obesity

Obesity is one of the main causes of diabetes. Studies show that 60 to 85 % of diabetics tend to be overweight. In the United States of America, about 80 percent of type –2 non-insulin dependent diabetics are reported to be overweight.

Excess fat prevents insulin from working properly. The more fatty tissue in the body, the more resistant the muscle and tissue cells become to body insulin. Insulin allows the sugar in the blood to enter the cells by acting on the receptor sites on the surface of the cells.

Older people often tend to gain weight, and the same time, many of them develop and mild form of diabetes because who are over weight can often improve their blood sugar simply by losing weight.

Stress and Tension

There is a known connection between stress and diabetes mellitus, those who are under stress and/or lead an irregular lifestyle, need to take adequate precautions and make necessary lifestyle adjustments.

Grief, worry and anxiety resulting from examinations, death of a close relative, loss of a joy, business failure and strained marital relationship, all a deep influence on the metabolism and may cause sugar to appear in the urine.

Smoking

Smoking is another important risk factor. Among men who smoke, the risk of developing diabetes is doubled. In women who smoke 25 or more cigarettes a day, the risk of developing diabetes is increased by 40 percent.

Lifestyle Risk

People who are less active have greater risk of developing diabetes. Modern conveniences have made work easier. Physical activity and exercise helps control weight, uses up a lot of glucose (sugar) present in the blood as energy and makes cells more sensitive to insulin. Consequently, the workload on the pancreas is reduced.

Avoid fats, meat and meat foods to control diabetes

Fats

The excessive use of fats has been linked to development of diabetes. A recent study at the University of Colorado Health Science Center, USA found that intake of an extra 40g of fat day increases the chances of developing diabetes by three times. Fat rich diet, especially one saturated with animal fat, seems to damage the insulin’s effectiveness. Research at the University of Sydney in Australia measured the saturated fatty acids in the muscles cells of older non-diabetic men and the women undergoing surgery and found that higher the presence of saturated fatty acids in the cells, the greater the insulin resistance. On the other hand, higher tissue levels of polyunsaturated fats, particularly fish oil, indicated better insulin activity and lower resistance. Fish oil differs from animal fats in that fish oil contains polyunsaturated fatty acids. One of the fatty acids called omega-3 is especially good for the heart—it lowers cholesterol and protects from atherosclerosis. In fact, the researchers also reported that intake of omega-3 fish oil to the subjects effectively overcame their insulin resistance.

In another study, Jennifer Lovejoy, assistance professor at Louisiana State of University, USA, studied and the eating habits and insulin activity among 45 non-diabetic men and women. About half of them were obese and the remaining half of normal weight. In both cases, higher fat consumption increased insulin resistance. This indicates, says Dr. Lovejoy, that even normal individuals who decrease their insulin efficiency and boost their vulnerability to diabetes.

Meat and Meat Foods

One of the most important nutrition guidelines to follow is to “eat less saturated fat.” A quick and simple way to do that is to eliminate meat products. They are high both in saturated fat and cholesterol content. People with diabetes have a greater risk of heart disease earlier in life. The practically useless calories added by saturated fats contribute to above normal body weight and obesity, putting a diabetic at greater of heart disease.

Flesh foods are extremely harmful for diabetes. They increase the toxemic condition underlying the diabetic state and reduce the sugar tolerance. Most diseases of the human body are caused by autointoxication of self-poisoning. The flesh of animals increases the burden on the organs of elimination and overloads and system with animal waste matter and poisons. Chemical analysis has shown that uric acid and other uric poisons contained in the animal body are almost identical to caffeine and nicotine, the poisonous, stimulating principles of coffee, tea and tobacco.

The renowned journal Lancet, reports that a patient of diabetes must be persuaded to consume less animal foods. However, in cold countries where meat and mat products constitute the bulk of the diet, patients of diabetes should limit their intake of animal products to eggs and white meal like fish and poultry. Even their use of should be kept to the minimum; all red meat and red meat products should be eliminated from the diet.
