Low folate in male diet linked to risk of offspring birth defects

Previous research has shown that what mothers eat during pregnancy affects the health of their offspring. But now, a new study suggests that a father's diet prior to conception could also play an important role in their child's health, particularly when it comes to consumption of folate. Folate, also known as vitamin B9, is found naturally in a broad variety of foods, including dark green leafy vegetables, nuts, beans, peas, fruit and fruit juices, dairy products, poultry and meat, eggs, seafood and grains. In 1998, the US Food and Drug Administration (FDA) required manufacturers to add folate to enriched breads, flours, cereals, cornmeals, pastas, rice and many other grain products, since these products are highly consumed in the US. The researchers, led by Sarah Kimmins of McGill University in Canada, say that in order for mothers to help prevent miscarriages and birth defects, it is well known that they must consume sufficient levels of folate. According to the Office of Dietary Supplements, a part of the National Institutes of Health, women of childbearing age should have 400 mcg (micrograms) of folate each day from dietary supplements and/or fortified foods, and this increases to 600 mcg a day for pregnant women. But the investigators note that whether a father's folate levels play an important role in the development of their offspring has been under-studied.

Frequently Asked Questions

Does the father's diet affect fertility and baby health UK?

Yes, new research suggests that a father's diet before conception can significantly impact their baby's health. Studies show that men with low folate levels may have an increased risk of their offspring developing birth defects, so it's important for both partners to focus on nutrition when trying to conceive.

How much folate should men take when trying to conceive?

While the NHS primarily focuses on folate recommendations for women (400 mcg daily), emerging research suggests men should also ensure adequate folate intake through diet or supplements. Men can boost their folate levels by eating dark green leafy vegetables, beans, peas, nuts, and fortified cereals as part of a balanced diet.

What foods are high in folate for male fertility UK?

Foods rich in folate that can support male fertility include spinach, broccoli, Brussels sprouts, asparagus, chickpeas, kidney beans, and fortified breakfast cereals. The NHS recommends eating a varied diet with plenty of vegetables and pulses to ensure you're getting enough B vitamins, including folate.

Should men take folic acid supplements when partner is TTC?

While NICE guidelines specifically recommend folic acid supplements for women trying to conceive, this new research suggests men may also benefit from ensuring adequate folate intake. Speaking with your GP about preconception health for both partners is advisable, particularly as 1 in 7 UK couples experience fertility issues.

Can low folate in men cause miscarriage or birth defects?

According to recent studies, low folate levels in fathers prior to conception may be linked to an increased risk of birth defects in their offspring. This research highlights the importance of both partners focusing on nutrition and lifestyle factors when planning a pregnancy.

What preconception vitamins should men take NHS advice?

The NHS recommends that men trying to conceive maintain a healthy, balanced diet rich in vitamins and minerals. While specific male preconception supplements aren't routinely prescribed on the NHS, ensuring adequate intake of folate, zinc, and selenium through diet or supplements may support sperm health and overall fertility.

How long before conception should men improve their diet?

Sperm takes approximately 2-3 months to develop fully, so men should ideally improve their diet and folate intake at least three months before trying to conceive. This gives the body time to produce healthier sperm, which may reduce the risk of birth defects according to the latest research.
