Many years ago....
Women ate what they could as there wasn't the variety there is now.
Smoked (if they were smokers obviously)
Drank
Carried heavy things
Cared for a family
Shopped,
Cooked
Cleaned
and did a whole host of things.
NOW : we can't eat this or that, can't drink, can't smoke, can't lift heavy items. can't do this, can't do that.....
hang on millions of women all over the world carry on as normal. Eat what your body is used to, and don't fuss over things. Worked for me first time round. Now expecting 2nd and am doing just the same again
