How you think, act, and learn is affected not only by the types of food you eat, but also by how the food is prepared, how and when you eat it, and what foods you eat together.

High tofu intake is associated with worse memory in elderly Indonesian men and women. Hogervorst E, Sadjimim T, Yesufu A, Kreager P, Rahardjo TB. Dement Geriatr Cogn Disord. 2008;26(1):50-7. Epub 2008 Jun 27. PMID: 18583909 DOI: 10.1159/000141484 CONCLUSION: The results for tofu consumption as a risk factor for low memory function may tie in with the Honolulu Asia Aging Study data. It is unclear whether these negative associations could be attributed to potential toxins or to its phytoestrogen levels. Estrogen (through which receptors phytoestrogens can exert effects) was found to increase dementia risk in women over 65 years of age. Tempe contains high levels of phytoestrogens, but (due to fermentation) also exhibits high folate levels which may exert protective effects. Future studies should validate these findings and investigate potential mechanisms.

"Eating high levels of some soy products - including tofu - may raise the risk of memory loss, research suggests. The study focused on 719 elderly Indonesians living in urban and rural regions of Java. ' The latest study suggests phytoestrogens - in high quantity - may actually heighten the risk of dementia. Lead researcher Professor Eef Hogervorst said previous research had linked oestrogen therapy to a doubling of dementia risk in the over-65s. She said oestrogens - and probably phytoestrogens - tended to promote growth among cells, not necessarily a good thing in the ageing brain. Alternatively, high doses of oestrogens might promote the damage caused to cells by particles known as free radicals. A third theory is that damage is caused not by the tofu, but by formaldehyde, which is sometimes used in Indonesia as a preservative. The researchers admit that more research is required to ascertain whether the same effects are found in other ethnic groups. However, previous research has also linked high tofu consumption to an increased risk of dementia in older Japanese American men. The researchers found high tofu consumption - at least once a day - was associated with worse memory, particularly among the over-68s. "

"Consuming tempeh can reduce the risk of developing dementia in the elderly, but eating tofu can increase it, said a joint study between universities here and in Britain on Wednesday. The study between University of Indonesia (UI), Indonesia Respati University, University of Loughborough and University of Oxford said people over 68 years of age who consumed tofu more than twice a day had a worse memory than those who rarely ate it. But if they also ate tempeh, the risk of dementia was reduced. "Tempeh consumption very likely offsets tofu's negative associations with memory," Professor Eef Hogervorst of the University of Loughborough said in a seminar on aging and health at UI campus in Depok, where she presented the result of the study. The study involved 712 respondents from Jakarta, Citengah in West Java and Yogyakarta, with ages ranging from 52 to 99 years. "

Pets are not just making the house became more lively or as a "guard" the house. Keeping animals was also able to help make us healthier. What are the effects of raising animals in the house? Push intelligence Research found that having a pet helps children read better, and even help a child's cognitive, too.

"Fatty acids can help children in exams and improve their behaviour in class and at home, a study suggests. Overweight children who took fatty acid dietary supplements showed dramatic improvements in concentration, reading, memory and mental agility. The advances that their brains made in three months would normally take three years, researchers found."

"Increasing the fatty acid content in children's diets can boost their mental abilities, scientists claim. Four overweight children given capsules containing omega-3 and omega-6 were said to have undergone three years' worth of development in just three months. The youngsters, aged between eight and 13, were also said to have made remarkable improvements in reading and problem-solving. Professor Basant Puri carried out the tests for a Channel Five documentary, Mind the Fat: Does Fast Food = Slow Kids?, to be shown on Thursday."

Blueberry Supplementation Improves Memory in Older Adults (dagger). Krikorian R, Shidler MD, Nash TA, Kalt W, Vinqvist-Tymchuk MR, Shukitt-Hale B, Joseph JA. J Agric Food Chem. 2010 Jan 4. [Epub ahead of print] PMID: 20047325 DOI: 10.1021/jf9029332 The findings of this preliminary study suggest that moderate-term blueberry supplementation can confer neurocognitive benefit and establish a basis for more comprehensive human trials to study preventive potential and neuronal mechanisms.
