The study aimed to determine the effect of pravastatin on venous thromboembolic events (deep venous thrombosis and pulmonary embolism) in older people. The study included 5.699 men and women aged 70-82 who were followed for an average of 3.2 years.

The study found that statin users had a 42% increased risk of venous thromboembolic events compared to those who did not use statins.

The study investigated the relationship of diet in cardiovascular disease and total death rates in type one diabetics. The study lasted for over seven years and included 2,108 type 1 diabetic patients aged 15-60 years who were free of cardiovascular disease at the start of the study.

Regarding saturated fat consumption, the study found:
(a) Total death rates decreased by 30% for every 10 grams per day increase in saturated fat consumption.
(b) Those who consumed the most saturated fat had a 16% reduced risk of cardiovascular disease compared to those who consumed the least saturated fat.

The results from the study reveal that a high saturated fat consumption is associated with a longer life and reduced risk of cardiovascular disease in type one diabetics.

This paper sought to identify different risk effects of statin therapy. The paper analysed seventy-two trials involving 159,458 patients.

The paper found:
(a) Statin users had a 9% increased risk of diabetes compared to non-users.
(b) Statin users had a 31% increased risk of elevated aspartate aminotransferase levels compared to non-users. (Elevated levels of aspartate aminotransferase indicate damage to liver, heart, muscle, kidney and brain tissues).
(c) Statin users had a 28% increased risk of elevated alanine aminotransferase levels compared to non-users. (Elevated levels of alanine aminotransferase indicate liver damage).

The data from this analysis of 72 trials shows that statins increase the risk of diabetes by 9%.

Pork helps to significantly increase nonheme-iron absorption

This study was published in the American Journal of Clinical Nutrition 2003 Jan;77(1):173-9

The study investigated the effect of small amounts of pork on nonheme-iron absorption from a meal presumed to have low iron bioavailability. In the study iron absorption was measured in 45 women, average age 24 years, who consumed four different meals.

The meals consisted of:
(i) The basic meal: rice, tomato sauce, pea purée, and a wheat roll. (phytate-rich meal low in vitamin C).
(ii) The basic meal + 25 grams of pork.
(iii) The basic meal + 50 grams of pork.
(iv) The basic meal + 75 grams of pork.

The study found:
(a) The meal with 25 grams of pork increased absorption of nonheme-iron by 20% compared to the basic meal.
(b) The meal with 50 grams of pork increased absorption of nonheme-iron by 44% compared to the basic meal.
(c) The meal with 75 grams of pork increased absorption of nonheme-iron by 57% compared to the basic meal.

The findings of the study reveal that small amounts of pork (over 50 grams) significantly increase nonheme-iron absorption from a phytate-rich meal low in vitamin C.

The objective of the study was to examine whether the use of statins is associated with the incidence of type two diabetes among individuals at high risk for type two diabetes participating in one-year lifestyle intervention study. The study included 2,798 non-diabetic individuals, aged 18–87 years,  who had elevated fasting glucose levels.

Lifestyle counselling was performed either in group sessions or individually. Advice was given on diet, weight control, meal frequency and quality, physical activity, smoking, alcohol use and diabetes as a disease in general. Group sessions were mainly weight maintenance or exercise groups and lectures concerning diabetes and lifestyle changes.

Fasting blood glucose levels are used to diagnose prediabetes and diabetes. Elevated blood glucose levels can damage your eyes, kidneys, nerves, and blood vessels.

The study found:
(a) Statin users had a 17% increased risk of developing type two diabetes compared to non-statin users.
(b) Fasting glucose levels increased by 0.08 mmol/L (1.44 mg/dL) in statin users, but remained unchanged in non-users.

The data from the study reveals that statin use increases the risk of type two diabetes in individuals at high risk of type two diabetes.

The study investigated the association between food and prostate cancer risk. The study included 130 patients with prostate cancer and 274 controls without cancer.

The study found:
(a) Those who consumed over four grams a day of fermented soy had a 102% increased risk of prostate cancer compared to those that did not consume any fermented soy.
(b) Those who had prostate cancer consumed 4% less fresh meat than than who did not have cancer.

The data from the study reveals that the consumption of fermented soy products was associated with a significant increase in prostate cancer risk.

The study examined the association between dietary protein intake and incidence of heart disease. The study included 80,082 women, aged 34-59 years, who were without a previous diagnosis of heart disease, stroke, cancer, hypercholesterolemia, or diabetes.

The study found:
(a) Women who consumed the most protein had a 26% reduced rate of heart disease compared to the women who consumed the least protein.
(a:i) Women who consumed the most protein also ate 7.8% more fat than women who consumed the least protein.
(a:ii) Women who consumed the most protein also ate 12.8% more saturated fat than women who consumed the least protein.
(a:iii) Women who consumed the most protein also ate 64.0% more cholesterol than women who consumed the least protein.
(a:iv) Women who consumed the most protein also ate 16.1% more red meat than women who consumed the least protein.
(a:v) Women who consumed the most protein also ate 32.1% less carbohydrate than women who consumed the least protein.
(b) Women who consumed the most animal protein had a 16% reduced rate of heart disease compared to the women who consumed the least animal protein.

The data from the study shows that low consumption of protein, fat, saturated fat, cholesterol and red meat is associated with higher rates of heart disease in women.
