Vegetable Oil Linked to Breast Cancer

New research in the International Journal of Cancer claims omega-6 polyunsaturated fatty acids, found in vegetable oil, may increase breast cancer-risk in postmenopausal women, but heterocyclic amines in cooked meat and fish DON’T up cancer-risk; Reuters reports.

I asked Dr. Fuhrman for his thoughts on the study. Here’s what he had to say:

Of course processed foods, including refined carbohydrates such as white flour and sugar increase a women's risk of breast cancer. And, the findings in this study are also logical, that the use of vegetable oils, which are also low-nutrient processed foods, would increase risk of breast cancer as well.

As humans we are designed to eat and thrive on natural foods in their natural state. Eating an avocado is nothing like consuming avocado oil and eating corn oil cannot be compared to eating corn. Oil is high calorie, low nutrient food; the definition of junk food. When we eat plant fats in their natural state, such as in seeds and nuts, the scientific studies are clear, they have the opposite effect (of oil), lowering risk of all-cause mortality and extending lifespan.

Even olive oil is junk food! Olive oil MIGHT be an improvement over saturated animal fats, but Dr. Fuhrman insists, processed oils are a MAJOR contributor to our overweight modern world.

As for heterocyclic amines, they’re NOT healthy either. The Physicians Committee for Responsible Medicine points to studies linking both grilled meat and grilled chicken with cancer-risk. Water-based cooking, like steaming, is MUCH safer.

Most olive oil sold in the US is not pure but "adulterated", a mixture of soybean, canola, or hazelnut oil. If olive oil is that beneficial, why don't they do an olive oil study in the US? Why is the study just done in the Mediterranean?

I don't think olive oil is all that healthy. In the studies that show it in a good light, I notice one of 2 things: 1) they are replacing saturated fats and trans-fats with olive oil rather than comparing in to raw nuts/seeds and avocado or 2) the rest of the diet is really healthy as in lots of fruits, vegetables, beans etc.
I think a study comparing identical diets with the difference being fat coming from olive oil (or other refined oils) vs. fats coming from raw nuts, seeds, avocado and whole olives would show refined oils in a negative light.

The body needs some fat, and oil should be used as a condiment and not a food group. Ever try to eat a spoonful of oil? Ugh. Also replacing sat fat in the diet with mono fat is a good thing. Some oils, like flaxseed oil, have proven benefits. But again, more is not better.

The body needs fat but not oil. Flaxseed is healthy, not extracted flaxseed oil. Healthy fats would be nuts,seeds and avocado.
