The COVID-19 pandemic has shown how important it is to have a nutritious diet and maintain a healthy weight.
And from there they decided the best course of action would be to.... well I don't need to repeat the last 18m but ffs 
Ultimately this is another drop in the ocean plan that certain people will probably lap up because it fits the look how much the SNP cares narrative, but in reality will make fuck all difference.
This study is interesting and well worth the read.

Basically: healthy diet and increased activity in schools + school led family workshops and cooking classes.
Conclusions The primary analyses suggest that this experiential focused intervention had no statistically significant effect on BMI z score or on preventing childhood obesity.
I'll admit I am a bit biased here but one of the responses has raised points I've been increasingly curious about for a while.

It's basically what the 'Fat Fiction' documentary talks about i.e. Obesity has risen in line with the demonisation of fat, the 'healthy' breakfast is the most important meal of the day rhetoric, and the advice to eat more fruit and vegetables.
The original data that a high carb low fat diet reduces heart disease was skewed by picking and choosing which random countries were included, and any subsequent lowering of heart disease could in fact be attributed to lower rates of smokers.
I'm not saying this is true, or trying to present this as facts and like I said, I'm a bit biased because I've just always preferred butter to marge, blue milk to green, cheese to crisps, disliked 90% of fruits and hated the way carbs made me feel. Also despised the thought of breakfast (much to the worry of my dear mammy growing up). As such I've always found it pretty easy to lose and maintain weight. I know exactly how a 2 sachet bowl of golden syrup porridge is going to make me feel for the rest of the day (hungry) and I can take it or leave it.
I have two daughters now and one is like me and naturally dislikes bread, potatoes etc while the other absolutely loves carbs.
Neither are obese, but it's the one whose favourite foods include mash, baked beans, and breakfast cereals who I constantly have to monitor because she is constantly snacky.
All this to say: I think if a targeted study in schools with the standard "healthy diet" makes no difference then the SNP are not only barking up the wrong tree with their Code of Practice for Children's Menus, they're not even in the same forest.
I agree with pp about education but I think there does come a time when we have to stop and actually check the education?
How many people do a 'CC' diet like SW or WW and either cannot stick to it (because it's incredibly difficult) or end up back where they started?
SW - where pasta is free, fruit is speed, and you should chop all the fat off your meat (the tasty filling part
).
