this is a very interesting article about how fruits help preventing all sorts of condition, INCLUSIVE diabetes.
"How Much Fruit is Too Much?
You may be asking yourself a simple question: if eating fruit is good for you, then how much fruit is too much? Is it possible to overeat on fruit, leading to worsening health, higher A1c values, increased blood pressure, increased risk for heart disease and weight gain?
In a study performed in 1971, researchers classified the effects of a “mainly fruit diet” to determine what happened to 17 people who ate 20 servings of fruit per day (9). On this regimen, people ate up to 200 grams of fructose per day, the equivalent of 8 cans of soda.
Researchers found that after 3 to 6 months on a mainly fruit diet, there were no adverse effects, and that body weight, blood pressure and insulin levels began trending down.
Following up on this research, in 2001 researchers tested the effect of 20 fruits per day on blood lipids and colon function, and found that within the first 2 weeks, total cholesterol dropped significantly (-40.6 mg/dL), as did LDL cholesterol (-37.9 mg/dL) (10). Although in this case it was a short-term study, they also reported zero adverse side effects of a diet packed with fruit.
Based on this evidence, it appears that there is no upper limit on the amount of fruit you can eat on a daily basis, and that any argument suggesting that fruit contains “too much sugar” is misinterpreting the scientific evidence."
"The rice-fruit diet was Dr. Kempner’s attempt at creating a no-salt, no-cholesterol diet containing almost pure carbohydrate. Dr. Kempner found that his rice-fruit diet reversed the following conditions:
Conventional diabetes wisdom states that foods high in carbohydrate energy will exacerbate diabetes and increase the requirement for insulin and medication. By that rationale, Dr. Kempner’s rice-fruit diet should have resulted in metabolic disaster for his patients living with type 2 diabetes.
According to standard diabetes advice, the rice-fruit diet should have increased insulin requirements, caused unwanted weight gain, and promoted cardiovascular disease. But it didn’t. Why? Because whole carbohydrates are NOT the enemy for people with diabetes.
Given that the diets designed by Rabinowitch and Kempner were both low-fat and low-calorie diets, many questioned whether improvements in insulin sensitivity and diabetes were simply due to weight loss, and not to decreased dietary fat.
To separate these two variables, James W. Anderson and Kyleen Ward conducted a study in 1979 in which they enrolled 20 subjects who had been living with type 2 diabetes for more than 20 years (16).
The researchers fed participants a diet low in fat diet and high in carbohydrates but not restricted in calories, and monitored changes in insulin requirements and blood glucose over time.
In order to study the effects of diet alone, they made sure that subjects ate enough to prevent them from losing weight.
Some subjects complained of physical discomfort from eating so much food, but the protocol ensured that all subjects remained weight stable.
By doing this, they could then study how insulin requirements changed on a low-fat diet, independent of weight loss.
The results of this study were nothing short of remarkable. Insulin requirements plummeted by an average of 58% in the group that ate a low-fat diet, whereas insulin requirements did not change in those eating the conventional diabetes diet.
Ten out the 20 subjects were able to discontinue taking insulin altogether, and those who continued insulin therapy were able to reduce their dosages between 7-98%.
The most surprising result was that more than 50% of subjects were able to discontinue insulin completely after only 16 days on a low-fat diet, even having lived with type 2 diabetes for multiple years.
In addition, as a convenient side effect of a reduced intake of dietary fat, cholesterol levels dropped an average of 29%, from 206 mg/dL to 145 mg/dL.
Most importantly, all patients in this study were able to reduce or discontinue insulin therapy and reduce their cholesterol levels without any changes in body weight, clearly demonstrating that less dietary fat results in less insulin need.
Just imagine what would have happened to their cholesterol levels if they added the world's most powerful cholesterol-reducing food – amla (Indian gooseberries)..."
