The Effect of Age on Taste Essay

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).

- Describe how cognitive functional and emotional changes associated with dementia can affect eating drinking and nutrition:

Dementia is a very common disorder that is more common in the older population. For people aged 60-69 the dementia rate is 1in 100, but in people over 80 the rate is 1in 6(A.Smith, 2011). Dementia is a terminal illness and the prognosis is grim, suffers are only expected to live 3 to 5 years after diagnosis (A.Smith, 2011). Dementia is divided into three stages early, middle and late. People can be in the late stage for many years. During the late stage the dementia patient suffers from a lot of different issues including but not limited to dysphagia, self-feeding, and eating problems. Nearly 50 percent of patients with dementia lose their ability to self-feed within 8 years after the onset of the disease (S.A. Thomas 2014).We know that malnutrition is a serious problem when it comes to dementia

The purpose of this project is to experiment if smell affects taste. In the hypothesis it is stated that when the nose is plugged the taste of a jellybean will

1.5 Explain why it is important to include a variety of food and drink in the diet of an individual with dementia?

1 Descride how congnitive, functional and emotional changes asspociated with dementia can affect eating, drinking and nutrition.

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) .

3. Humans are born with approximately 10,000 taste buds. After the age of 50, seniors can begin to lose taste buds. Additionally, many seniors lose their sense of smell. This can make enjoying food and getting enough calories difficult for some elderly.

From birth, the body and mind go through physical and cognitive changes that human beings will have to adapt to throughout life. Some individuals lose mental and physical abilities age they age that allow them to live a normal lifestyle. The most common age-related physical changes include hearing impairment, weakening vision, and the increasing probability of multiple chronic conditions such as arthritis, hypertension, heart disease, diabetes, and osteoporosis (Abeles, 1998). The most common cognitive changes associated with normal aging are short-term, or primary, memory loss, long-term, or secondary, memory loss, and the overall levels of performance in sustained attention. Other issues relative to aging and cognitive memory impairments are anxiety disorder, panic disorder, chronic pain, and mood disorders. This issue may cause several social, medical and family problems as individual

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

It is a known fact that all measures of physiological function decline in human aging. While genetics certainly play a role in the declining of physiological function with age, it can be argued that a fundamental part of aging can be reflected by chemical processes resulting in the appearance of harmful side products of the normal metabolism over time. When enzymes speed up reactions it is harder to slow them down. At the same time side reactions are constantly occurring and more and more unwanted side products are continuously being formed.

Older adults are thus slower in receiving information through sensory receptors, slower in transmitting, processing, and interpreting information, and are slower in acting upon it” (Shulman, Silverman, & Golden).

Cognitive aging is worthy of study for many reasons. The more knowledge that is uncovered about cognitive aging, the closer to possibly finding ways to slow the process down, decrease the intensity of the symptoms, or maybe prevent it all together. If there are possible ways of doing so it is important to find them. The “what” and “when” of cognitive aging has made advances, but the “why”, “where”, and “how” are still to be uncovered. We further our knowledge of the “why”, “where”, or “how”, or uncover the full truth, without knowing the full truth about the “what” and “when”. Finding out more about one might lead to learning more about another. Expanding our knowledge on cognitive aging has the potential to increase someone’s quality of life. It has the potential to increase that family member’s quality of life. Cognitive aging effects more than the victim, it effects their

As individuals age changes occur physiologically that are part of normal aging. These changes occur in all organ systems and can impact an individual’s quality of life. The changes related to aging can be attributed to an individual’s genetic make up, lifestyle, physical activity, and dietary lifestyle. Being able to differentiate between normal changes in aging against disease process is important because it can help clinicians develop a plan of care (Boltz, Capezuti, Fulmer, & Zwicker, 2012). Creating an accurate plan of care for older adults will greatly impact their quality of life.

Receding of the gums is a notable condition in this bracket. As mentioned earlier, old age is associated with various medical conditions. Medications used to
