High fat dairy foods, whole milk for fertility or to get pregnant
The best time to prepare your body for a healthy pregnancy is long before you make a decision to become pregnant. The sooner you start eating well, the more likely you are to get pregnant. For both men and women, food and fertility are linked. You need to stick to a balanced diet to boost your chances of conceiving and of having a healthy baby.

Eat several servings of fruit, vegetables, grains such as whole wheat bread, and calcium-rich foods such as yogurt, cheese, and milk every day. Certain vitamins and nutrients — such as vitamins C and E, zinc, and folic acid — are important for making healthy sperm. Not getting enough nutrients can affect your periods, making it difficult to predict when you ovulate. And you may not ovulate at all if you've lost a drastic amount of weight or are obese.

Eating well prior to pregnancy helps prepare your body for the nutritional demands of building a baby over the next nine months. Not only have physical disorders been linked with ill-nutrition before and during pregnancy, but neurological disorders and handicaps are a risk that is run by mothers who are mal-nourished, a condition which can also lead to the child becoming more susceptible to later degenerative disease.

Fats, or lipids, are nutrients in food that your body uses to build nerve tissue (like the brain) and hormones. Your body also uses fat as fuel. If fats that you've eaten aren't burned as energy or used as building blocks, they're stored by the body in fat cells. This is your body's way of thinking ahead: By saving fat for future use, your body plans for times when food might be scarce.

"What you eat affects everything from your blood to your cells to your hormones," says Cynthia Stadd, a nutrition specialist at the Berkeley Center for Reproductive Wellness and Women's Health in New York City. According to the American Pregnancy Association, a nonprofit that promotes reproductive health, you should allow three months to a year for dietary changes to take root.

Begin making healthy changes three months to a year before you conceive. The evidence shows that healthy nutrition and fertility is linked for both men and women. Below is a list of suggestions for healthy nutrition prior to conception. Maintaining a diet of fruits, vegetables, whole grains, lean meats, and dairy products regularly should provide you with the recommended dietary allowance of vitamins and minerals for the most favorable reproductive functioning.

It is known that good nutrition before pregnancy is important because of the amount of "resources" childbirth requires. The process of pre-pregnancy nutrition is a process of "building up" the immune system in preparation of pregnancy, and is known as being one of the major factors in determining the success rate of conceiving healthy children.

Shedding some pounds, or gaining a few if you're underweight, while you're attempting to get pregnant is a good idea, since you want to be as close as possible to your recommended weight when you conceive. Being over- or underweight can make it harder to get pregnant. Also, overweight women have more pregnancy and birth complications, and underweight women are more likely to have a low-birth-weight baby.

Oysters contain high levels of zinc, which is a nutrient that contributes to semen and testosterone production in men, and in ovulation and fertility in women. There are several studies that indicate that deficiencies in zinc impede upon both male and female fertility. Maintaining the recommended dietary allowance of zinc of 15 mg a day can help keep your reproductive system functioning suitably.

It is recommended that women get at least 1,000 mgs (three 8 oz glasses of skim milk) of calcium a day if they are considering getting pregnant. Calcium may be obtained from natural sources such as cottage cheese, low-fat yogurt, canned salmon, sardines, rice, and cheese.

Women who are trying to get pregnant may increase their odds of conceiving by eating ice cream or drinking a glass of whole milk each day, suggests a new study. The study also hints that women trying to conceive may want to avoid low-fat dairy foods, as these seem to be linked to non-ovulation.

In comments to Reuters Health, study chief Dr. Jorge E. Chavarro, from Harvard School of Public Health, Boston, said: "It may be reasonable to consume one or two daily servings of full-fat dairy foods temporarily while trying to get pregnant ... of course, while also keeping a low saturated-fat intake and without increasing the intake of total calories."

Over the course of 8 years, Chavarro and colleagues assessed the diets of 18,555 married women without a history of infertility who attempted to get pregnant or became pregnant.

During the study, 2165 women were examined medically for infertility and 438 were found to be infertile due to lack of ovulation, or anovulation.

The researchers found that women who ate two or more servings of low-fat dairy foods per day, particularly skim milk and yogurt, increased their risk of ovulation-related infertility by more 85 percent compared with women who ate less than one serving of low-fat dairy food per week.

"The opposite was true for full-fat dairy foods, particularly whole milk," Chavarro told Reuters Health. Women who ate at least one serving of high-fat dairy food daily reduced their risk of ovulation-related infertility by 27 percent compared to women who ate one or fewer high-fat dairy servings per week.

In "specific foods" analyses, the researchers observed that women who ate ice cream two or more times per week had a 38 percent lower risk of ovulation-related infertility compared to women who ate ice cream less than once a week.

Recommendations that adults consume three or more daily servings of low-fat milk or equivalent dairy products "may well be deleterious for women planning to become pregnant as it would give them an 85 percent higher risk of anovulatory infertility according to our findings," Chavarro said in a statement.

He advises that women wanting to conceive to swap low-fat dairy foods like skim milk and yogurt for high-fat dairy foods like whole milk and ice cream, while at the same time maintaining their normal calorie intake and limiting their overall intake of saturated fats in order to maintain good general health.

Once a woman becomes pregnant, Chavarro said, she should probably switch back to low-fat dairy foods.

The ideal range of weight for women wishing to conceive children is thought to be optimal at body mass indexes between 20 and 26. If this, again, is used in conjunction with good nutrition and diet before pregnancy in terms of a normal balanced diet, then reserves of micronutrients, providing materials for pregnancy, would also be maximized.
