Grapes help rats in the rat race of life. Powdered grapes made up 3% of their diets.
Researchers studied the effect of regular table grapes (a blend of green, red and black grapes) that were mixed into a powdered form and integrated into the diets of laboratory rats as part of a high-fat, American style diet. All of the rats used were from a research breed that is prone to being overweight.
They performed many comparisons between the rats consuming a grape-enriched diet and the control rats receiving no grape powder. Researchers added calories and sugars to the control group to balance the extra calories and sugars gained from getting the grape powder.
Lower blood pressure and improved glucose tolerance were among the indicators pointing at benefits from eating grapes.
After three months, the rats that received the grape-enriched diet had lower blood pressure, better heart function, and reduced indicators of inflammation in the heart and the blood than rats who received no grape powder. Rats also had lower triglycerides and improved glucose tolerance.
The effects were seen even though the grape-fed animals had no change in body weight.
So there you have it. Eat some grapes or raisins. My guess is that assorted berries rich in phytonutrients will deliver many of the same benefits. Try to get the various types of phytonutrients in your diet.
