The Effect of Age on Taste
The sense of taste has to be one of the most important human senses. It gives an individual the ability to recognize consumables that are encountered on a regular basis such as a favorite steak platter or a favorite wine. However, when that individual reaches a particular age the sense of taste deteriorates, which can result in potentially dangerous conditions such as malnourishment or susceptibility to diseases. This problem of taste loss due to aging needs to be studied more because it can effect both the physical and mental health of many elderly people.
When elderly individuals try to live life with a weakened ability to recognize certain food flavors or any other consumable item, their dietary needs can be greatly affected. A certain number of foods are not going to taste good enough to satisfy the appetites of the elderly, so they might resort to using unhealthy eating habits. For example, they could lose the motivation to eat certain foods such as vegetables or meats and increase the consumption of foods that are low in nutritional value such as candies or pastries. This shift can result in health problems such as a loss in bone mass, a weakened immune system, weak muscles, and high blood pressure.
Elderly citizens need to acquire a specific amount of nutrients in order to maintain a healthy life style. Spence (1989) mentioned that diets which maintain adequate levels of vitamins and minerals and also consist of 50 to 55% carbohydrates, 12 to 15% proteins, and 25 to 35% fats are recommended for persons over the age of 50. In order for the elderly to live up to a healthy diet, they need to consume nutritious foods that will taste good to them. The problem with this situation is how to h...

Research on taste aversion in rats led to the discovery that suppression of the immune system can be influenced by:
Modern human brain sizes are significantly smaller than Neanderthal’s and so are their brain cavities. TAS2R38 is the gene that controls taste. For Neanderthals, having a bitter taste “system” could have kept them from poisoning themselves by accident.
...lution tasted as compared with pervious testing due to no prior documentation. This test also did not consider the amount of time it took for R2 to taste the solutions. Furthermore, this experiment does not test injury or defect in the brain that may effect the functioning of the facial nerve, but not actually be an issue with the nerve itself. While the hypothesis was substantiated for both subjects, more long term assessment or re-testing is necessary to assuredly confirm both R1 and R2 have in tact facial nerve functioning.

At one point in time, if someone was infertile then they couldn’t have kids. There was nothing that could be done. Not anymore. Now doctors can provide them another option called in vitro fertilization. Not only that but biomedical engineers have advanced this field to even greater extents. They can use gene manipulation to prevent certain genetic diseases such as asthma, muscular dystrophy and even greatly reduce the chances of disease rampant in the family history, such as breast cancer. One of these ways is the "three parent" idea. Reproductive surgeons will use the mother’s egg, but replace the mitochondria that contains the disease with second healthy mitochondria from a different mother resulting in three parents total. Contributing to the genetics of the offspring, scientists are projecting a new possibility: designer babies. These would be completely "customized" children. Manipulation of eye color, hair color, facial structure, height, size, numerous other changes are all possibilities. This is a modern field of medicine covering new ground. However these designer babies present major ethical issues. People feel scientists are taking full control of nature and lines are being crossed that shouldn't be. For example a scientist wanted her kid to look like her, therefore she implanted an embryo into herself and had a blonde hair blue eyed baby, just as she wanted, but should be genetically impossible. This research in designing a baby should be regulated; it is ideal for preventing devastating diseases that will worsen a human’s future life but completely controlling a baby's appearance and possibly their personality, though possible, should be illegal in the United States.

This paper is on dementia, a late-life disorder, as it pertains to the geriatric population. “It is estimated that 24.3 million people around the world have dementia and that, with an estimated 4.6 million new cases every year, we can expect about 43 million people and their families to have to handle the challenge of dementia by 2020.” (McNamera, 2011) I will cover three relevant points concerning this disorder that cause changes in the brain.
Aging and old age for a long time presented as dominated by negative traits and states such as sickness, depression and isolation. The aging process is not simply senescence most people over the age of 65 are not Senile, bedridden, isolated, or suicidal (Aldwin & Levenson, 1994). This change in perspective led the investigation of the other side of the coin. Ageing is seen as health, maturity and personal Royal growth, self-acceptance, happiness, generatively, coping and acceptance of age-related constraints (Birren & Fisher, 1995). Psychological und...
Since ancient times, it has been clear that some people lose mental sharpness (cognitive function) as they age. However, in 1906, the German neurologist Alois Alzheimer began an autopsy of a woman from Frankfurt, that had died after several years of progressive mental deterioration. From the accounts of the doctor, family, and friends of the woman, Alzheimer put together her mental state prior to death, and described the woman as being marked by increased confusion, disorientation, and memory loss.Taking advantage of staining techniques that had recently been established, Alzheimer noticed an odd disorganization of the nerve cells in the womanís cerebral cortex, the part of the brain...
The world of foods and nutrition has changed dramatically in recent years. It used to be eggs, red meat and whole milk, but now many doctors recommend leafy green vegetables, fruits, beans and whole grains. The old way has gotten many people into trouble. Heart disease, Cancer, and other problems have become an epidemic. That’s why nutrition is so important. Many children are struggling with weight and many have artery damage.
Ultimately, these physiological changes result in different nutritional needs for the elderly. The Food and Nutrition Board of the National Academy of Sciences issues the Recommended Daily Allowances for healthy people over the age of 51. However, these RDAs are limited in that they have been derived from studies of younger, healthy populations and do not account ...
In an attempt to define ageing one must take in consideration the biophysiological together with the psychosocial aspects; these two aspects are intertwined.
268). This disorder is often a result of damage to one or more of these areas, illustrating the complex, separate systems involved in perceiving, integrating, and making observations on this information, as well as the possibility for these systems to become altered or interrupted as a result of lesions, tumours, or other forms of damage. It is also worth noting that those suffering from Alzheimer’s or other forms of dementia show a reduction in their stereognosis ability, showing that some neurological diseases may impact these systems as well (Gerstmann, 2001, p. 271). Apart from the impact on making associations between previously perceived objects and immediate tactile sensory input, individuals with this disorder would rarely experience significant distress or impact to their quality of life as it does not directly affect interactions with others or their
Flavor is based on a combination of factors. These factors include taste, smell, texture, and temperature. The following experiment’s main focus is the flavor of food based on the combination of smell and taste. Have you ever pinched your nose while eating and noticed that you can’t taste your food? In this report you will learn how the nose and tongue work together to create flavor. Your sense of smell and sense of taste are very important when deciding the flavor of food.The tongue and nose influence each other more than you may think.
