I have heard that apart from consuming dairy products, gum can help your breast size increase. Is this true? Well, can any type of food help your breast grow (without making any other parts of your body gain weight)?
It is a myth that dairy products can increase breast size. Indeed, drinking milk or eating cheese is healthy — source of protein and calcium — and you might see an improvement in your overall health, but there is no scientific evidence that your cup size will necessarily increase.
A Japanese company B2Up claims that its Bust-Up gum can increase breast size but there is no solid evidence that it actually works, despite a study that the company cites as a basis for its claim. It does have some good natural ingredients (Pueraria mirifica or Kwao Krua) but we have not heard from anyone who has been able to get reliable results after chewing the gum. They also use a racequeen in their ad but in almost all cases these Japanese idols have breast implants. Japan is also the maker of Suplitol, F-Cup Tea and F-Cup Cookies that seem to do the same, though, they are all as useless as hoodia is for weight loss and all other breast enlargement pills are for getting bigger breasts.
Regarding your question about any type of food help your breast grow (without making any other parts of your body gain weight), the answer is No. We would not have anyone with small breasts on the planet if a food like that were known. Generally speaking, women who put on weight do see larger breasts but they also gain weight around the waist and thighs — definitely not something that you want to do.
