Do not replace saturated fat with refined carbohydrates

Filed Under Wellness | Tagged With: , , | | Comments Off on Do not replace saturated fat with refined carbohydrates

It is wrong to say eat less fat; the real message should be eat more fresh fruits and vegetables.

While advocating low-fat diets, it is easier for patients to understand the advice given in terms of foods, e.g., “Eat more fresh fruit” rather than nutrients, or “Reduce your intake of fat to less than 30% of your total energy intake.”

The message to reduce fat has been translated by food manufacturers and consumers into a potentially harmful set of food choices.

Instead of replacing high-fat foods with naturally low-fat foods with other benefits, such as fruits, vegetables, legumes, and whole grain foods, consumers have often increased their consumption of low-fat or “fat-free” varieties of naturally high-fat foods, such as fat-free snack or junk foods.

The result is an increase in refined carbohydrates which lowers good HDL cholesterol concentrations with a possible increase in the incidence of type 2 diabetes and obesity.

  • Caffeine is the most widely consumed stimulant in the world.
  • It is consumed in the form of coffee and tea.
  • At present there is no scientific data for promoting or discouraging coffee and/or tea consumption in the daily diet.
  • Short-term benefits include mental alertness and improved athletic performance.
  • Short-term adverse effects include headache, anxiety, tremors and insomnia.
  • Long-term adverse effects include generalized anxiety disorder and substance abuse disorders.
  • Long-term benefits are dose-dependent. Caffeine is associated with a reduced risk of Parkinson’s disease, Alzheimer disease, alcoholic cirrhosis, and gout. Coffee, both caffeinated and decaffeinated, is also associated with a lower risk of type 2 diabetes.
  • Heavy coffee intake may trigger coronary and arrhythmic events in susceptible individuals, although coffee intake is not considered a long-term risk factor for myocardial disease.
  • Most studies show a modest inverse relationship between coffee consumption and all-cause mortality.
  • Caffeine withdrawal is a well-documented clinical syndrome with headache being the most common symptom. (Source: Uptodate)

All about Diabetes

By Dr K K Aggarwal
Filed Under Wellness | Tagged With: , | | Comments Off on All about Diabetes

  • Type 2 diabetes can be delayed or prevented, and both types 1 and 2 diabetes can be managed to prevent complications
  • People with diabetes are nearly two times more likely than people without diabetes to die from heart disease, and are also at greater risk for kidney, eye and nerve diseases, among other painful and costly complications. Type 2 diabetes can be delayed or prevented, and both types 1 and 2 diabetes can be managed to prevent complications.
  • In type 1 diabetes, the body does not make insulin. In type 2 diabetes the body makes insufficient insulin or does not use insulin well.
  • Gestational diabetes occurs in some women during pregnancy. Though it usually goes away after the birth, these women and their children have a greater chance of getting type 2 diabetes later in life.
  • Type 2 diabetes has begun to affect young people.
  • Losing a modest amount of weight — about 15 pounds — through diet and exercise can actually reduce your risk of getting type 2 diabetes by as much as 58 percent in people at high risk.
  • In type 1 diabetes, tight control of blood sugar can prevent diabetes complications.
  • Choose healthy foods to share.
  • Take a brisk walk every day.
  • Talk with your family about your health and your family’s risk of diabetes and heart disease.
  • If you smoke, seek help to quit.
  • Make changes to reduce your risk for diabetes and its complications — for yourself, your families and for future generations.

Low-heat cooking may reduce insulin resistance

Traditional Ayurveda cooking recommends low heat cooking and now a western study endorses it.

Low–temperature cooking reduces insulin resistance among overweight women as per a 4–week study published in the journal Diabetes Care by Alicja B. Mark, PhD, from the department of nutrition, exercise and sports, faculty of science, University of Copenhagen, Denmark, and colleagues.

Cooking at high temperature such as with baking, roasting and frying — induces formation of advanced glycation end products (AGEs), which are associated with inflammation and believed to impair glucose metabolism in patients with type 2 diabetes. Common high–AGE foods include bakery products, cooked meat and roasted coffee.

In the study patients randomized to a high–AGE diet were instructed to fry, bake, roast, or grill their food, eat bread with the crust and choose other high–AGE foods from a list. The low–AGE group was told to boil or steam their food, eat bread without the crust, and choose lower–AGE foods from a list. They were also randomized to supplements of either fructose or glucose.

At 4 weeks, no effect was seen from the fructose or glucose on insulin resistance, as assessed by the homeostasis model assessment of insulin resistance (HOMA–IR) and the calculated insulin sensitivity index (ISI) or on any secondary measures. But the AGE content of the diet did make a difference. Weight, BMI, and waist circumference all decreased in both the high– and low–AGE groups, but to a greater degree among those in the low–AGE group compared with the high–AGE group. Overall, the low–AGE group consumed about 15% more protein, 10% more carbohydrates, and 22% less fat than did the high–AGE group

  1. Exercise more Exercise has various benefits including preventing weight gain, controlling blood sugar levels, and other conditions. A minimum of 30 minutes of physical activity every day is very beneficial.
  2. Eat healthy A diet rich in whole grain, fruits, and vegetables is very good for the body. Fibrous food will ensure that you feel fuller for a longer period and prevent any cravings. Avoid processed and refined food as much as possible.
  3. Limit your alcohol intake and quit smoking Too much alcohol leads to weight gain and can increase your blood pressure and triglyceride levels. Men should limit drinks to two per day and women to one per day. Smokers are twice as likely to develop diabetes as non-smokers and therefore, it is a good idea to quit this habit.
  4. Understand your risk factors Doing so can help you in taking preventive measures at the earliest and avoid complications.

Caffeine is the most consumed stimulant in the world. It is consumed in the form of coffee and tea. At present there is no scientific data for promoting or discouraging coffee and or tea consumption in the daily diet. Short term benefits include mental alertness and improved athletic performance. Short term adverse effects including headache anxiety tremors and insomnia. Long term adverse effects include generalized anxiety disorder and substance abuse disorders. Long term benefits are dose dependent. Caffeine is associated with a reduced risk of Parkinson s disease Alzheimer s disease alcoholic cirrhosis and gout. Coffee both caffeinated and decaffeinated is also associated with a lower risk of type 2 diabetes. Heavy coffee intake may trigger coronary and arrhythmic events in susceptible individuals although coffee intake is not considered a long term risk factor for myocardial disease. Most studies show a modest inverse relationship between coffee consumption and all cause mortality. Caffeine withdrawal is a well documented clinical syndrome with headache being the most common symptom. Source Uptodate

Diet is linked to the diabetes epidemic

A study published in the journal Diabetes Care, highlights the importance of the whole diet rather than focusing on certain foods or food groups that might be beneficial.

A diet rich in whole grains, fruits and vegetables (leafy green), nuts and low–fat dairy may help people lower their risk of type 2 diabetes by 15% over 5 years than those who ate the lowest amounts of these foods.

In contrast, adults whose diets were high in red meat, high–fat dairy, refined grains like white bread plus beans and tomatoes, saw their diabetes risk go up by 18% as a group.

Type 2 diabetes is closely linked to obesity and it is well–known that maintaining a healthy weight through diet and exercise reduces the risk of developing the disease. Diet affects diabetes risk independent of a person’s weight.


stable CAD and type 2 diabetes

Among patients with stable CAD and type 2 diabetes, measures of autonomic function––such as heart–rate recovery after exercise––may help predict the risk of short–term adverse cardiovascular events as per a study.

A second study reports that autonomic dysfunction is strongly linked with a greater risk of severe hypoglycemia in patients with type 2 diabetes.

The best way to avoid it is to have intensive glucose control with hemoglobin A1cs that are definitely below 7.5 and ideally below 7. On the other hand, if you have (HbA1c) levels above 8, certainly above 9, you have a very high likelihood of having the problem (within) 10 or more years.

The two studies were published online August 19, 2013 in Diabetes Care.
Test

  • The patients performed a test on an exercise bicycle, which allowed the researchers to determine their heart–rate recovery, defined as the drop in heart rate from the rate at maximal exercise to the rate one minute after stopping the exercise.
  • Blunted heart–rate recovery after exercise: defined as a drop in heart rate of less than 21 beats per minute––had a 1.69–fold greater risk having a cardiovascular event than their peers.
  • Holter: Blunted heart–rate turbulence (<3.4 ms/R–R interval) had a 2.08–fold increased risk of an event
  • Low heart–rate variability (<110 ms) had a 1.96–fold greater risk of having a cardiovascular event.
  • Heart–rate variability at three times: during a Valsalva maneuver, deep breathing, and going from lying down to standing.
