Taste Disorders

Changes due to the aging process also need to be addressed. Calcium reabsorption increases especially in women after the menopause, this decreases bone density. Lean tissue decreases as fat increases with age; there is also a decline in the percentage of body water meaning that body temperature is more difficult to control. Thirst decline and decreased renal function means that older people can become dehydrated (Copeman 1999). The function of the bowel reduces, meaning that the elderly are more susceptible to indigestion and constipation. The risk of constipation is also increased with Parkinson’s disease (Parkinson’s UK 2011). The final consideration is the deterioration of the sensory system. Taste, smell, vison, pain and touch all decline meaning that food may not be as appealing (Copeman 1999).

1. The main cause of sensory loss is aging, as we age our senses become less and less.

In previous studies, Frank and Byram’s article suggest that taste and smell interactions are dependent on taste and odor. In their experiments, they gave subjects strawberry

As we age, our brain and nervous system go through natural changes. An aging adult may experience memory loss, decreased touch sensation, change in the perception of pain, change in sleep pattern, decreased coordination and increased risk for infection (Ignatavicius, 2013, p. 912) .

Receptor proteins recognize bitter-tasting compounds on the surface of taste cells. There are approximately 30 genes for different bitter taste receptors. The gene for the PTC taste receptor, TAS2R38, was identified in 2003. Sequencing identified three nucleotide positions that vary within the human population (Kim et al.); each variable position is termed a single nucleotide polymorphism (SNP). One specific combination of the three SNPs, termed a haplotype, correlates most strongly with tasting ability. In this lab, non-tasters (homozygous recessive, tt) can determine their genotype without having to run the PCR and electrophoresis because non-taster gene is recessive. Thus, the only way for them to express recessive phenotype is to have the tt alleles of

The olfactory system is the area responsible for smell; it is the fist area that deteriorates when the brain is affected by dementia (Garrett, 2013). This can lead to several types of cognitive concerns that affect older adults ability to eat like apraxia (they may have problems using their eating utensils), amnesia (they may forget to eat), decreased executive functioning (they may eat from other people’s plates or not control the quantity of food they eat), and agnosia (they may not respond to

believe it isn’t possible anymore to correct that, we are so used to what we eat that we don’t like

Without this sense I would be a way less picky eater. There are so many restraunts I won’t go to because they use too many spices in their food and it just so happens that I am a really picky eater. There are many vegetables that I won’t actually eat if I didn’t have the sense of taste, like broccoli, squash, and zucchini. In a survival situation I would be able to survive longer than the other people because I could eat bugs and pinecones and I wouldn’t be able to taste them. To lose the sense of taste is wouldn’t be the worst one to live without but I would still hate to lose

You can actually start to lose some of your senses as well. The video Healthbeat states “in our early 30’s our smell peaks to its full potential from then on there is a gradual decline in our 40s and 50’s.” Your sense of smell can actually diminish as much as 60% as you get older. Another important sense that can be lost with age is hearing. Hearing loss is the most common health problem and is also under diagnosed and treated. Jacqueline and Lynn talk about how they did not even know that they were losing their hearing. After taking a hearing test and receiving hearing aids, they couldn’t be happier. Jacqueline, Lynn, and Jim Ferman encourage everyone watching the video to get a hearing test because hearing loss is affecting nine million older people just in this country. Without a hearing aid it may be difficult to have a conversation with someone or even hear if someone is trying to talk to you. At an old age, there are many people to interact with such as your significant other, friends, kids, and even grandchildren. Good communication is essential to living a good life. Lynn and Jacqueline love to dance and I think that they are more pleased with their line dancing classes now that they can hear the music and each other

The research report “Adult Picky Eating: Phenomenology, taste sensitivity, and psychosocial correlates,” was published in the international research journal, Appetite, by the University of Pennsylvania. The authors of the report wrote in a very conventional manner or in other words, adhered to this genre’s conventions. The intended audiences of this article are psychologists and scientists and we know this due to esoteric diction and the organization throughout the paper. Keywords and phrases such as “cognitive symptoms of disordered eating,” ARFID, psychopathology and references to DSM-V tell us this article is geared to more specifically psychologists. The article is written in the scientific method format and includes data written in scientific notation and key terms like chi square analyses, p-values, and the golden ratio symbol. Unintended audiences could be people interested in the study or anyone who may

This can sometimes lead people to thinking that it’s just a case of someone being a “picky eater.” However, many suffering with SED believe that there is only a finite amount of foods that they can eat. Extremely picky eaters experience food differently than the rest of us. Since there is not much data on this disorder, there are not significant findings as to how many people suffer from SED. Survey show in 2010 to better understand how many people consider themselves picky eaters, and approximately 7,500 people responded. Many people are often embarrassed of this disorder and don’t want to seem difficult about their eating habits. Sufferers of SED have an inability to eat certain foods. "Safe" foods may be limited to certain food types and

Food has constantly been changing and improving to be better to eat. Such as making it look and smell better. If something doesn't look appetizing, you aren't going to want to eat it.

This is a very common question asked by many people and by researching, I have gathered enough information to answer this question. What most people recognize as “taste” is actually the result from their sense of smell. So therefore it is not what you taste it is what you smell. The human tongue has about 10,000 taste buds, yet the human tongue only recognizes four basic taste sensations. The four basic taste sensations that are recognized are classified as sweet, sour, bitter, and salty. A 5th sensation that the human tongue recognize, yet is not considered to be basic is called Umami that is energized by MSG. Umami was discovered by the Japanese and it means delicious in Japanese. Umami taste buds taste savory flavors such as spicy, salty,

The process of tasting is happy for me, I enjoy the feeling that food melt in my mouse and the flavour disperse gradually. But it also exists some problems, I have the keen taste sense and smell over the average,

I eventually grew to like the taste in later years. The incorporation of these childhood 'treats' came be seen in the food diary that I kept. They had become a familiar part of my diet as I began to demonstrate brand loyalty. I had a preference of KFC over Burger King and McDonalds, Pizza Hut over Pizza Pizza, etc.
