Food and Fertility,pregnancy diet

The heart-healthy diet with more fruit and vegetables,less meat and carbs,more healthy fats and few or no trans fats recommendations behind The fertility diet might influence ovulation because they affect insulin levels.Insulin levels, in turn, can affect sex-hormone-binding globulin, which can affect the amount of free androgen in a women's body.too much can suppress ovulation.

Two recommendations in the fertility diet are backed by relatively solid science.For a women with irregular ovulation,attaining a healthy weight and taking a multivitamin with folic acid can improve her odds of getting pregnant.Being overweight or underweight has been shoen to suppress ovulation,because both conditions throw off a woman's natural hormone levels.

In a major study of vitamins and folic acid to reduce the incidence of neural-tube defects in babies,the researchers noted a trend they hadn't expected.The women taking the vitamins were not only more likely to have twins.

The weakest recommendation in the fertility diet is the notion that ice cream and whole-fat dairy products will increase fertility.Even the study authors note in the book that it would be an overstatement to say that are even a handful of studies on the subject.
