So far, the kind of stuff that I have found out is, as long as you're making sure to get the basic nutrients that you need, your baby is going to be fine. But this, maybe could tell us a little bit more about whether if I eat bad things, what it might, what effect it might have on my baby. Talking to Hazel, just briefly over the phone was interesting. Her cohort study Started getting women before they even became pregnant, so it meant that they had an idea of what they were eating long before they became pregnant. "It's not easy for a woman to eat a healthy diet, if everyone's eating unhealthy diets around her, so this isn't just a message for woman it is a message for men as well. The two things I've focused in on at the moment - one is the importance of the womans diet before during the pregnancy on her children, because the pathway that she sets up for eating for herself are what she then uses in the quality of diet she feeds her children. The other side of it is finding what we've shown about low vitamin D levels, being linked to later bone health in children." Today I'm here at the Royal Veterinary College, and it's cause I've found this really interesting research about junk food and rats, and the sort of affect on the offspring of rats when their mothers eat junk food during their pregnancy, so I'm really excited to find out a little bit more about this. Junk food is defined by: food that is very dense in energy, and contains a lot of fat, sugar, and or salt. So we fed pregnant rats either the controlled diet, which is this standard laboratory rodent feed, and the experimental groups were fed the junk food diets, so they had free access all to of this junk food, and they also had access to the standard healthy chow. This roughly represents how much fat you would get from a control group. So offspring fed a controlled diet, a healthy diet, from gestation, up to the end of adolescence. The second group, is when the mother's are fed a healthy diet in pregnancy and lactation. And then at weening the offspring are given free access to junk food, up to the end of adolescence. So they eat what they want. And the last group is the fat taken from offspring fed the junk food diet from fetal life up to the end of adolescence. So you can see they've got almost twice as much abdominal fat than those born to a mother fed a healthy, balanced diet. By being exposed to junk food diet before birth, through the metal dieting, pregnancy and lactation, those offspring developed obesity earlier in life, they overwrite and they developed a greater taste for junk food than those born to mothers fed a healthy diet. By seeing all of the fat that had been laid on, into these babies stomachs and abdominal regions, and livers from their mothers being fed junk food during pregnancy, and during the breast feeding stage. I started to realize A little bit more about my own you know, responsibility in making sure that not only do I make sure that I get all nutrients that I need, but that I also don't overdue it and dont take in to much energy, and dont take in too much saturated fat. I went and had a salad for lunch after that. I sent off for my grant, and a week later I got it paid into my account. I didn't end up spending it on food at all actually. I'm going to make sure I spend it on something healthy, and something that goes towards the well being of my baby Because that's something I've definitely taken away from talking to these scientists. There's something you can do at every stage of the pregnancy. If you are gonna beat yourself up over eating a biscuit with some full fat cheese its just not going to be worth it, but It's just important not to eat that the whole way through.
