List of Foods Having Aphrodisiac Qualities

Apart from satisfying our hunger and taste buds, foods also have fringe benefits to them. Some foods are claimed to be able to increase arousal in both male and female. Here are the theories behind the aphrodisiac potential foods.

Arousal for Men
There are some components in oysters that have aphrodisiac qualities. For one thing, oysters contain varying levels of dopamine. Dopamine is a neurotransmitter that affects the arousal center in our brain. The effect is straight away. Secondly, oysters contain high level of zinc, that is important in raising level of testosterone in men. The effect, though, is not immediate.

Arousal for Women
Parsley and truffles may have aphrodisiac potential, as these food smell like that of androsterone, a pheromone usually responsible for men's musky body smell. This smell can influence arousal in women.

More Arousal
Ginger, cayenne pepper and garlic also can stimulate the arousal centers in the brain. Garlic which has anti-clotting properties can affect libido by increasing blood flow to brain and sex organs.

The smooth texture of chocolate and the cocoa's serotonin creating chemical, tryptophan, contributes to chocolate's aphrodisiac potential.


Happy experimenting potentially aphrodisiac foods! Best served with soft dimmed light or maybe during candlelight dinner. Do share stories of your experiences with these food (^-^)

Stress Causes Yeast Infections

Do you often experience recurrent yeast infections? If you do, make sure you start taking things easily now.

Chronic stress may be a factor causing vaginal yeast infections with Candida albicans, according to Swedish study, and as reported in American Journal of Obstetrics and Gynecology.

The study was conducted by involving 35 healthy women and another 35 women who had at least 4 yeast infections during the past year. Most commonly, these women are infected with Candida albicans.

The researches collected saliva samples from the participants in order to measure the stress hormone, cortisol. Usually cortisol levels rise in the morning. However on these infected women, the cortisol levels was blunted compared with the healthy women. A shallow rise in cortisol indicates ongoing stress.

The researches also found that more patients than the healthy women group, had a history of other vaginal infections such as genital warts, bacterial vaginosis and genital herpes. The researchers suggest that recurrent yeast infections may be a sign of reduced local immunity.

Further studies are needed though. In the meantime, slow down your pace, take deep breath and relax as much as possible. Don't let yourself sink in stress. Additionally, to help keep the yeast away, tips from my gynae: do make sure you iron your underwear after each laundry.

Men: All The More Reasons To Have Frequent Sex

A US study. published in Journal of the American Medical Association, suggested that men who have active sex life or masturbate frequently reduced their chances in developing prostate cancer.

This topic indeed has always been controversial among experts. Previous research suggests that increased production of testosterone, a male hormone, can faciltate the growth of prostate cell. However, this new study suggests that frequent ejaculations may decrease the concentration of chemical carcinogens that accumulate in prostatic fluid, and thus may reduce the development of crystalloids that are associated with prostate cancer in men.

This study results found that men who ejaculate 13 times a month or more, were much less likely to develop prostate cancer than men who do it 4-7 times a month. In comparison to men who ejaculate 4-7 times a month, men who ejaculate between 13-20 times a month had 14% lower lifetime risk; and 33% lower lifetime risk for those ejaculate 21 times and more a month.

These findings still need further investigation though. The previous study that concluded increased prostate cancer risk with higher sexual activities was published in the journal Epidemiology in 2002.

'Man Boobs' in Young Boys

If you happen to be a fan of lavender and tea tree oils, you may want to watch out and use it carefully if you have boys at home.

New England of Journal Medicine has published a study that suggests these lavender and tea tree oils can cause young boys to grow 'man boobs'. These oils can act in similar way to hormone oestrogen. They can also block male hormones that control both masculine characteristics.

It is indeed very rare for young boys to develop temporary breast enlargements during puberty. However, it does happen to very few unlucky boys. The term for this condition is called prepubertal gynaecomastia.

The case involved the 4-year-old "who was using absolutely nothing on his skin except a lavender oil preparation that his mother had obtained from a homeopath". Her mom always rub his chest and body using lavender oil every night, because she, as we all know too, that lavender has some healing properties. The boy start to develop 'boobs'. It was only several months after stopped using the lavender oil, his breasts returned to normal size.

However, further study should be conducted to determine the prevalence of prepubertal gynaecomastia in boys using products containing lavender and tea tree oils. Until then, personally, I would rather to have my boys stay clear from these oils, and forbid them from using soaps, shampoos, lotions, hair gels or other stuffs containing lavender and tea tree oils.

Fight Against Cancer With Broccoli

Good news for all of us who like to eat broccoli, well even those of you who do not like it, we all should start taking in more broccoli into our diet.

A study by Institute of Food Research in England has shown that broccoli can affect hundreds of genetic changes. To name a few: to strengthen genes that could fight against cancer, and to eliminate genes that could promote tumor.

Besides having isothiocyanate, broccoli also contain sulforaphane which yield extra immunity to fight against cancer.

Memory Loss Might Be More Serious Than We Think It Is

Forget where you left your house keys? or where you put your mobile phone? or where you left your glasses? Sounds familiar? It is for me! This condition maybe caused be a virus. Gosh!

Viruses that can affect your brain range from virus of common cold to polio. They can affect brain and cause steady damage, reported by US researchers from Minnesota.


Their study suggests that virus-induced memory loss can accumulate over the lifetime of a person. Eventually it can lead to clinical cognitive memory deficits. This study has been published in the latest issue of the journal Neurobiology of Disease.


The name of the virus is picornaviruses. They have affected more than 1 billion people around the world each year.


The researchers include viruses that cause polio, colds, and diarrhoea. On average, people contract these illness 2-3 times a year.


How these viruses affect our brain, is that when we contract the illness, the viruses cross into the brain and cause a variety of brain injuries. For example, the polio virus can cause paralysis.


The researchers studied the affect of picornavirus family members on mice, and It showed that the viruses injured parts of the brain responsible for memory. In fact, they infected mice with a virus called Theiler's murine encephalomyelitis virus, which is similar to human poliovirus. Infected mice later had difficulty learning to navigate a maze. Some were barely affected, while others were completely unable to manage.


When the mice were killed and their brains examined, a correlating amount of damage was seen in the hippocampus region, related to learning and memory.


The reserachers also added that one virus particularly likely to cause brain damage is enterovirus 71, which is common in Asia. It can cross over into the brain and cause encephalitis, a brain inflammation that can lead to coma and death.


"We hypothesise that mild memory and cognitive impairments of unknown aetiology may, in fact, be due to accumulative loss of hippocampus function caused by repeated infection with common and widespread neurovirulent picornaviruses."


Meanwhile, other viruses can kill brain cells. They include the herpes virus and HIV.
