Do certain food cravings point to certain baby genders? Ppl have been saying sweet means boy, salty means girl. but others also told me the reverse. Which is true?

Not true, your taste bud just changes it taste, everything taste bland and that is why the craving starts. You start imagine to have several kind of taste to satisfy your taste bud. Craving is just an excuse to eat. You can crave anything but do not consume the same food too often. Make it varies.
