You really don't need a doctor to answer this. If you know people who have eaten garlic regularly for health purposes, you might notice that they suddenly lose all their friends.
I have been told that monks refrain from garlic due to its aphrodisiac properties - but if anyone takes it to improve their sexual prowess, they better make sure their partner is either on garlic too or has a damaged sense of smell! The rancid, pungent and musty odour will more likely kill the mood.
OK, joking aside, it is true that certain foods can cause one to suffer from body odour, known as bromhidrosis.
So what are the usual suspects? The journal Medscape states that the "omission of certain foods may be of value if these factors can be isolated or identified as contributory factors to the bromhidrosis. Common culprits include curry spices, onions, garlic and alcohol."
But not all of us are affected in the same way and some of us have a greater predisposition to suffer from this condition than others.
Some of these factors are not modifiable, such as being born with a genetic predisposition. Other factors, however, are modifiable. We can do something about poor hygiene, obesity and even diabetes, such as using antiperspirants and soap, losing weight and taking diabetes medications.
