The study, which assessed the intake of various types of fat in the diet relative to success with IVF found that high intake of saturated fat (animal fat such as beef, pork, and dairy products) was associated with a reduced ovarian response. It also found that increased trans fat (often found in doughnuts, Danish pastries, French fries and fried foods in general) and polyunsaturated fat (most vegetable oils) were associated with decreased embryo quality.
However, increased monounsaturated fat (for example, olive oil) was associated with an increased delivery rate. In fact, women in the upper third of monounsaturated fat intake had a birth rate almost three and a half times as high as women in the lower third of intake!
So what do we recommend? Choose to eat foods high in monounsaturated fat, while limiting your intake of other types of fat. About 2/3 of the fat in avocados is monounsaturated and 78% of the fat in olive oil is monounsaturated. Olive oil is great for salads and cooking. Add Avocado to your salads and omelets or on sandwiches instead of mayonnaise. Nuts are also a good source of monounsaturated fat, with macadamias having the most. Try sliced avocado on multigrain bread, with olive oil instead of butter. When dining out have any bread with olive oil and balsamic.
The bonus will be if you stick with this diet for good, you will also live a longer and healthier life. Infertility is turning out to be a wake-up call for general health!
