Give your coffee habit a gorgeous pointy boot – at least when you are trying to get pregnant. There has been much research done of the effects of caffeine on women and men who are trying to conceive.  Numerous studies, including a recent study done at Montreal’s McGill University, have shown a correlation between high caffeine consumption and pregnancy loss. Caffeine may cause delayed conception and increased incidence of miscarriage in women who consume well over 300 milligrams of caffeine per day, or three cups of brewed coffee.

Some caffeine is fine – as long as you keep it very limited.  But how much is too much? A 6-ounce cup of regular coffee has about 100 milligrams of caffeine, whereas most 12-ounce cans of cola or 6-ounce cups of tea have about 30 to 50 milligrams. Caffeine contains in most soda drinks: 12 ounce cans of cola or 6-ounce cups of tea have about 30 to 50 milligrams of caffeine.

This means that one cappuccino, or one espresso (but not ristretto), one mug of American coffee or one mug of home-brewed java is fine. But skip that cola – for starters, it’s loaded with sugar, not to mention dozens of extremely unnatural and potentially toxic substances. Sugar-free colas and soft drinks are even worse. We’ll discuss it in more details in upcoming chapters.

To be absolutely safe it’s best to limit caffeine consumption to less than 100 milligrams of caffeine per day. Switching to decaffeinated coffee, which contains less than 10 milligrams of caffeine a cup, would reduce your caffeine intake to less than 200 milligrams a day. Also good raw cocoa nibs and chicory that smells like coffee but has none of its Viagra-for-brains properties.

Coffee is highly addictive substance. You may need to cut back gradually to prevent or lessen withdrawal symptoms such as headaches. Herbal and green teas may help, but watch out for caffeine contents in these beverages, too. Most doctors agree that two cups of green tea instead of one cup of brewed coffee are a safe substitute.
