It’s often said you are what you eat.

But it seems that what your mother ate is also important.

研究 points to a woman’s diet before she becomes 妊娠している 影響する／感情ing the 遺伝子s of her 未来 child.

Preparation: A woman's diet before she becomes pregnant affects the genes of her future child, new research suggests

準備: A woman's diet before she becomes 妊娠している 影響する／感情s the 遺伝子s of her 未来 child, new 研究 示唆するs

What is more, pre-conception diet may have a life-long 衝撃 on the as yet unborn child’s health.

研究員 Andrew Prentice, of the London School of Hygiene & 熱帯の 薬／医学, said: ‘The 重要な message is that a mother’s 栄養 before she becomes 妊娠している is 最高の-批判的な.

‘There is a lot going on before the moment of conception.’

The science is still in its 幼少／幼藍期, but it could lead to women who want to start a family 存在 advised to take a cocktail of ビタミンs and other food 補足（する）s ahead of pregnancy.

To pin 負かす／撃墜する the 影響 of a mother’s diet on health, Professor Prentice 熟考する／考慮するd women in 田舎の West Africa, where the 示すd seasons lead to 際立った changes in the foods eaten.

Working with 同僚s from the 医療の 研究 会議’s 部隊 in the Gambia, he 手段d the 集中 of さまざまな nutrients in the 血 of nearly 170 newly-妊娠している women.

Half had conceived at the 高さ of the 雨の season and half had become 妊娠している at the 頂点（に達する） of the 乾燥した，日照りの season.

Good sources of the nutrients needed to make chemical changes include green leafy vegetables

He also scrutinised the デオキシリボ核酸 of their babies after they were born and quizzed other 地元の women about their diet through the seasons.

Crunching the results together showed a （疑いを）晴らす link between a woman’s diet and her child’s 遺伝子s.

Crucially, it was what she ate before pregnancy that was important ? not what eaten when carrying the child.

The difference 伴う／関わるd ‘epigenetic’ changes to the baby’s デオキシリボ核酸.? These aren’t 突然変異s but 化学製品 changes that 影響する／感情 when 遺伝子s become active and how active they are.

Not all of our 遺伝子s are active all of the time, and if they are under or over-active, it can 原因（となる） problems.

Building blocks: Choline, found in eggs, in another influential nutrient, the study found

It is not known if the changes 設立する here 影響する／感情 health but, in other work, Professor Prentice has 設立する linked pre-pregnancy diet to the chemistry of 遺伝子s 伴う／関わるd in obesity, 癌 and the 免疫の system.

Some changes can be erased over time, others are life-long.

Nutrients needed to make the 化学製品 changes 含む ビタミンs B2, B6 and B12, 同様に as choline and methionine and folic 酸性の.

Professor Prentice said that while it is too 早期に to give advice, good sources of these 構内／化合物s 含む, milk, green, leafy vegetables and protein.

Women are already advised to take folic 酸性の, or ビタミン B9 in the run-up to pregnancy.

The professor said: ‘Now 研究 is pointing to the need for a cocktail of nutrients, which could come from the diet or from 補足（する）s.

‘What is pretty thrilling is that we seem to have 攻撃する，衝突する on something that has 世界的な consequences for women trying to conceive.’

Variations: The diet differences involved 'epigenetic' changes to the baby's DNA (pictured). These are chemical changes that affect when genes become active and how active they are

Almost ten years ago, scientists showed the nutrients in a mouse’s diet before pregnancy can alter the colour of the coat of her 未来 pup.

The 最新の 研究, published in the 定期刊行物 Nature Communications, is the first to definitively link preconception diet with epigenetic changes in people.

It is part of a growing 団体／死体 of 研究 that points to a child’s health 存在 programmed 早期に in life ? 含むing in the womb and even before conception.

It is argued that these 早期に days 形態／調整 a child’s chances of everything from developing 糖尿病 in their 40s and 50s to having a heart attack in old age.

It is even said that life 見込み can be traced 支援する to those 早期に days and months, as can a lifelong 戦う／戦い of the bulge.
