This work by the Harvard School of public health states that while small trails have indicated that the amount of vitamin C contained in a typical multivitamin and taken in the beginning of the development of a cold "might ease symptoms" however, for the "average person, there's no evidence that megadoses make a difference or that they prevent colds." (2009) It is related as well that studies examining Vitamin C supplements and "heart disease, cancer, and eye diseases such as cataract and macular degeneration also show no clear patterns."

Vitamin C is a vitamin found in many of the fruits/vegetables we eat including citrus fruits, broccoli, sweet peppers and potatoes. Vitamin C has an important role in many processes in our bodies. Research has proved that Vitamin C is a powerful antioxidant and a necessary cofactor for the production of collagen. Early indicators show that Vitamin C may play an even large role in the treatment of the common cold and possibly disease prevention.
Vitamin C offers the benefit of being an Antioxidant. Antioxidants are responsible for protecting our body's cells from free radicals. Free radicals can oxidize various nutrients and cells. If allowed to reach large amounts, the free radicals can be extremely harmful, that's where Vitamin C is helpful. By donating electrons, Vitamin C serves as an antioxidant that neutralizes free radicals and protects other substances from their damage. Vitamin C protects other nutrients from being oxidized (destroyed)…...

Vitamin C is not endogenously created in the human body, which is why it is essential that human beings receive enough Vitamin C in their diet. Diseases like scurvy can result from inadequate intake of Vitamin C, also known as L-ascorbic acid. Vitamin C performs a plethora of functions in the human body. It is an antioxidant, it is involved in protein metabolism, and is "required for the biosynthesis of collagen, L-carnitine, and certain neurotransmitters," (National Institutes of Health, 2016). Because of the role of collagen in wound healing, it can be said that Vitamin C facilitates wound healing (NIH, 2016). Because of its antioxidant functions, Vitamin C is also critical for optimal immune system functioning (NIH, 2016). Vitamin C also improves the absorption of plant-based iron, or nonheme iron (NIH, 2016). Vitamin C is water soluble and is excreted in the urine.
Absorption rates are optimal at moderate levels of…...

Vitamin C for Common Cold
What is Vitamin C?

Vitamin C, also known as ascorbic acid, is a water-soluble ingredient that is essential for the health of human beings. It is essential for normal growth and development and it has consumed regularly. Since Vitamin C dissolves in water, the excess amounts leave the human body through urine and this means the body needs a constant supply of this vitamin everyday. The body cannot store vitamin C in any form.

One of the primary role of vitamin C is to repair the body cells and tissues and to prevent free radicals and toxins from getting accumulated in the body. It repairs wounds and makes them heal faster. The free radicals are known to play a role in cancer and heart diseases and good amount of vitamin C everyday helps to prevent any damage.

For example, serum beta-carotene, retinol, and alpha-tocopherol levels rose in autumn months. Vitamin C serum concentrations were higher in the winter and spring.
Male participants revealed higher serum retinol concentrations than females, although male and female respondents already differed in terms of age. Younger respondents did have higher levels of beta carotene. Smoking had a stronger effect on lowering serum levels of vitamin C and beta-carotene than on retinol. In some cases, smoking tobacco had a strong effect on lowering serum levels of vitamins. In short, the current research suggests connections between lifestyle habits, age, and diet on blood concentrations of vitamins and can be used for health care workers to advise patients on their diet and lifestyle choices.

On the other hand, too much of a good thing can sometimes be even more harmful than too little. In that regard, it is very important to understand the role of vitamin D, both because of its role in maintaining our health, as well as because of the potential for harm associated with excessive supplementation.
Unlike other vitamins and minerals, vitamin D is not readily available through diet because its primary source is natural sunlight. The U.S. FDA recommends a daily dose of 200 IU, which according to medical authorities, is sufficient to protect against osteomalacia, a medical condition characterized by softening of the bones. However, because vitamin D requirements fluctuate depending on how much sunlight a person receives and are difficult to satisfy through diet alone, 200 IU is considered the RDA in the absence of regular exposure to natural sunlight.

Vitamin D is necessary for the proper absorption of…...

Vitamin D Supplementation increases Voluntary Physical Activity Levels in Nursing Home Patients
Over the course of a semester does vitamin D3 supplementation, and the resultant increase in muscle strength and bone density, lead to increased physical activity in nursing home residents in the absence of added encouragement?

The elderly often suffer from low serum levels of vitamin D, reduced muscle strength, and decreased bone density (reviewed in: Hamilton, 2010). Muscle biopsies have revealed that the muscle fibers most affected in the elderly are type II, the 'fast twitch' fibers. When a person begins to fall they instinctively attempt to prevent or break their fall and this reaction depends heavily on fast twitch muscle fibers. The elderly therefore suffer from an increased risk of falling down and bone fractures. Although conclusive evidence has yet to be found that low serum levels of vitamin D cause this condition, there is a large body of…...

Calcifediol Supplementation Toxicity
Vitamin D Supplementation: Concerns about Toxicity

Vitamin D (calciferol) is so essential to health that all vertebrates can produce this nutrient endogenously when the skin is exposed to ultraviolet light (Hoffmann, Senior, Mager 2015; Standing Committee et al. 1997). Vitamin D can also be obtained from fish and modern-day fortified food products. When exposed to sunlight, 7-dehydrocholesterol in the skin is converted to previtamin D3 (cholecalciferol) and then vitamin D3, which is then hydroxylated by liver enzymes to form 25-hydroxyvitamin D3 (25(OH)D3; calcifediol). The biologically active form is finally created when calcifediol is hydroxylated once more by a mitochondrial enzyme in the kidneys to form 1,25-dihydroxyvitamin D (1,25(OH)2D; calcitriol).

The two most common forms of dietary vitamin D supplementation are cholecalciferol and calcifediol, but the biological activity of the latter is 5 times that of the former (Standing Committee et al. 1997). The downstream effect of 1,25(OH)2D production is increased…...

, 2010). egardless of the cause, infant SV is linked to "significantly more symptoms of wheezing disorder and clinical allergy than controls and were more likely to be sensitized to common inhaled allergens" (Todd et al., 2010). The number of studies and the number of subjects is still small, but the correlations have been consistently large enough to suggest that a serious bout of SV-bronchiolitis in infancy is linked to later lung problems such as asthma, wheezing, and atopy. Therefore, M.C.'s parents should be educated about the possibility that M.C. may experience breathing problems in later life, and told to advise her primary care physician of her SV diagnosis and hospitalization.

Vitamin deficiency in food can cause different health deficiencies like Pellagra, Scurvy, ickets among others. Most of these negative health outcomes are evidenced in the staple diet of those in the developing and poor countries. We shall understand some diets that cause these deficiencies in this essay.
Pellagra

The characteristics of Pellagra are mental afflictions, diarrhea, and dermatitis. Inadequate quantity of nicotinic acid in the diet that causes niacin deficiency in the body causes Pellagra. Over dependence on maize is an observed cause of Pellagra. Though Maize contains Niacin, it cannot be absorbed in the body in the raw form. It has to be passed through alkaline hydrolysis to be absorbed by the body. Jowar also contains adequate quantities of Niacin. However, the presence of leucine in jowar inhibits the process of absorption of niacin. Additionally, chronic alcoholism is one known cause of lack of ability to absorb of niacin (through poor…...

Controlled experiments are those in which groups are separated into control and experimental. Neither group knows what they are receiving, so they may or may not be receiving a sugar pill or something else. The control group is essential for comparisons -- what happens in the control group often determines how the experimental data is interpreted (Scientific Control Group, 2008).
A double blind experiment is one in which some of the participants are prevented from knowing certain information about the study that might lead to bias (conscious or subconscious) thus skewing the results. Blinding can also be imposed on researchers, subjects, funders, or any combination in which one wishes to protect the data integrity. In the use of new drugs, blinded experiments are necessary because a patient might feel better if they think they are receiving a powerful new medicine -- the placebo effect. It is impossible, however, to double blind…...

Too much fat, on the other hand, leads to problems like high blood pressure, fatigue, joint problems, heart issues -- the list goes on. My recommended daily intake of calories from fat is 662.02 out of a total of 2364.36, or 28%. On Day Three, my total intake of calories from fat was 433.9 out of a total caloric intake of 1237.2, or 35%. This suggests that I need to watch the amount of fat I am including in my diet, even while it appears as though need to increase my basic caloric consumption.
The type of fat consumed is also important; 35.6% of the fat I consumed on Day Three was saturated, compared to the 32.1% recommended daily allowance.

The latter two can be enjoyed cooked or cut up fresh, in a salad. If she uses spinach instead of lettuce in the salad, the subject can boost fiber even further and add a little more iron to her diet. Current consumption of iron is just under recommended amounts. High fiber fruits, including apples, oranges and pears, will not add significant calories if consumed in moderation (How Do I Get More Fiber).
The subject's intake of saturated fat and cholesterol were both under acceptable limits. ith respect to other nutrients, the subject's levels of Vitamin C, thiamin, phosphorus, iron, zinc, and selenium were all near acceptable levels. Potassium consumption was a bit lower than recommended; this could be remedied with consumption of oranges, already recommended to boost fiber, or bananas.

Lifestyle Changes and Nutrition in Infertility Management

Infertility, defined as the inability to conceive after one year of unprotected intercourse, affects approximately 10-15% of couples worldwide. While medical interventions like assisted reproductive technologies (ARTs) often take center stage in infertility treatment, lifestyle modifications and proper nutrition play a crucial role in improving fertility outcomes.

### Lifestyle Changes

1. Maintain a Healthy Weight:
Obesity and underweight can impair hormonal balance and ovulation. Maintaining a healthy Body Mass Index (BMI) can improve fertility in both men and women.

2. Regular Exercise:
Moderate-intensity exercise, such as brisk walking or swimming, for 30 minutes most days of the week, can....
