Walnut Help Improve Cholesterol Levels

No matter what type of diet you are doing is a diet low in fat and high in carbohydrates or a diet high in fat and low in carbohydrates, both ways are considered effective for weight reduction.
However, if there have other health mission, which is to improve cholesterol levels, a new study conducted by researchers from the University of California found that eating a diet that is balanced with the walnut is the most effective way to regulate cholesterol levels.

To see more about how diet can affect the levels of lipid, or fat levels in the blood which together with proteins to form lipoproteins, known also as cholesterol, the researchers recruited 245 women with overweight to obesity in a weight loss program for 1 year ,
The participants were randomly divided into three groups of different diets; one group a diet low in fat and high in carbohydrates; the second group a diet high in fat and low kerbohidrat; and a third group followed a diet high in fat and low in carbohydrates are rich in walnuts as a source of polyunsaturated fatty acids.

Then, blood samples were taken from the participants to measure their cholesterol levels at baseline and six months later.

When looking at the results for the six-month diet, the findings showed that all three groups lost the amount of weight that is relatively the same, the average weight loss stands at 8%.
However, when looking at the cholesterol levels of participants, it was found that dietary third group, namely a diet high in fat and low in carbohydrate-rich walnut, has the effect of the most profitable on lipid levels of the body, lowering levels of low-density lipoprotein (LDL), which is better known as bad cholesterol, and increase levels of high-density lipoprotein (HDL).

"What we found is that a diet high in healthy oils can improve lipid and cholesterol levels. However, participants who consume unsaturated fats other than walnuts, do not get the same benefits," said study author Cheryl Rock.
The research team also measured the participants' insulin sensitivity. As individuals who are overweight often have insulin resistance, a condition in which the body's cells become resistant to the hormone insulin, is associated with an increased risk of diabetes, heart disease, and cancer.
These findings suggest that women who are sensitive to insulin to lose weight the most when following a diet low in fat and high in carbohydrates.

But as the third group diet, this diet did not have a beneficial effect on cholesterol levels if they are not offset by walnut consumption.
