Can Vitamin C Prevent or Treat Cold Symptoms or is it a Myth?

Colds are the leading cause of doctor's visits and the number one reason for absences from work and school.

Vitamin C was first touted for the common cold in the 1970s but studies started as early as 1747 for scurvy. read here…

Vitamin C is probably one of the most well-known vitamins out there. At the very first sign of cold symptoms, many people reach for a bottle of vitamin C supplement. Do you? Vitamin C is such a widely accepted treatment for the common cold that we seek it out in lots of products such as fortified juices, cough drops, and tea.

In the past 40 years, numerous epidemiological and placebo-controlled trials have examined the effect of vitamin C supplementation on the prevention and treatment of colds. More than 30 clinical trials with over 10,000 participants have examined the effects of taking daily vitamin C in doses up to 2 g/day.

Overall, experts have found little to no benefit in using vitamin C (disapoiting isnt it?) to prevent or treat the common cold. A review of data from a variety of databases found that regular vitamin C consumption may reduce the duration of cold symptoms in both adults and children, but it does not decrease the severity of cold symptoms

In 2010, researchers looked at all the scientific studies and found that taking vitamin C every day did not prevent the number of colds that a person got. In some cases, however, it did lead to a slight improvement in symptoms.

HOWEVER, IF THE VITAMIN C IS STARTED AFTER COLD SYMPTOMS APPEAR, THERE WAS NO BENEFIT SEEN AT ALL.

But highly physically active people training in stressful and extreme conditions such as soldiers training in the Arctic and marathon runners (2-3 gym sessions is not highly-active) may benefit from supplementation. In this group, taking vitamin C on a daily basis cut their risk of catching a cold in half. Top 10 Foods Highest in Vitamin C read here…

A wise man once said

“Prevention is better than cure”
but do we listen?

So what does all this mean?

I am sure you don’t want to hear this but taking vitamin C every day, you are not likely to have any fewer colds. However, you may have colds that are a day or two shorter and it do not prevent a cold or affect symptom severity.

Do you want to be more disappointed? Read on… Seven (7) separate studies showed that when vitamin C was started after cold symptoms appeared, vitamin C was no more effective than placebo at shortening the duration of cold symptoms.

Is Vitamin C Safe to Take?

In general, vitamin C is safe to take when ingested through food sources such as fruits and vegetables. (Top 10 Foods Highest in Vitamin C read here…) For most people, taking vitamin C supplements in the recommended amounts is also safe.

Higher doses of vitamin C greater than 2,000 milligrams per day for adults say cause kidney stones, nausea, and diarrhoea.

If you're unsure about taking vitamin C for colds, talk to your health care provider. Your doctor can answer any questions (we all hope so) about vitamin C and colds and about any other dietary supplement that you are taking.

Top 10 Foods Highest in Vitamin C - are you thinking about oranges?

Top 10 Foods Highest in Vitamin C – Are you thinking about oranges?

RodrigoPeres.com

Most of the time when someone talks about Ascorbic Acid (vitamin C), oranges spring to mind… You may be surprised but oranges do not rank No.1.

When talking about vitamin C, is probably because they are trying to get rid of a cold (does it really prevent cold? Read below) but there are more to vitamin C then just maintaining a strong immune system.

Vitamin C is an essential nutrient required by the body for the development and maintenance of:

> Scar Tissue

· > Blood Vessels

· > Cartilage

Vitamin C is also necessary for creating:

· > ATP

· > Dopamine

· > Peptide Hormones

· > Tyrosine

As a powerful antioxidant, vitamin C helps lessen oxidative stress to the body and is thought to lower cancer risk.

Most forms of cardiovascular disease, joint disease, cancer, eye disease, thyroid disease, liver disease, and lung disease require special emphasis on vitamin C intake. The process of ageing itself requires special attention to vitamin C. In addition to these broader categories, several specific health conditions also require special emphasis on vitamin C.

These specific health conditions include:

Acne
Alcoholism
Alzheimer's disease
Asthma
Autism
Depression
Diabetes
Irritable bowel disease
Parkinson's disease

DID YOU KNOW?
Vitamin C serves a predominantly protective role in the body. As early as the 1700's, vitamin C was referred to as the "antiscorbutic factor," since it helped prevent the disease called scurvy. This disease was first discovered in British sailors, whose sea voyages left them far away from natural surroundings for long periods of time. Their body stores of vitamin C fell below 300 milligrams, and their gums and skin lost the protective effects of vitamin C. Recognizing limes as a good shipboard source of vitamin C, the British sailors became known as "limeys" for carrying large stores of limes aboard ship.

How do cooking, storage, or processing affect vitamin C?

Vitamin C is highly sensitive to air, water, and temperature. About 25% of the vitamin C in vegetables can be lost simply by blanching (boiling or steaming the food for a few minutes). This same degree of loss occurs in the freezing and unthawing of vegetables and fruits. Cooking of vegetables and fruits for longer periods of time (10-20 minutes) can result in a loss of over one half the total vitamin C content. When fruits and vegetables are canned and then reheated, only 1/3 of the original vitamin C content may be left. Consumption of vitamin C-rich foods in their fresh, raw form is the best way to maximize vitamin C intake.

How do other nutrients interact with vitamin C?

Vitamin C has significant interactions with several key minerals in the body.

Supplemental intake of vitamin C at gram-level doses can interfere with copper metabolism. Conversely, vitamin C can significantly enhance iron uptake and metabolism, even at food-level amounts.

Vitamin C also has important interactions with other vitamins. Excessive intake of vitamin A, for example, is less toxic to the body when vitamin C is readily available. Vitamin C is involved in the regeneration of vitamin E, and these two vitamins appear to work together in their antioxidant effect.

How much should I be taking?

The U.S. Food and Nutrition Board of the Institute of Medicine recommend a daily intake for:
Men 18+ years old = 90 milligrams daily
Women 18+ years old = 75 milligrams daily
Pregnant women 18+ years old = 85 milligrams daily
Breastfeeding women 18+ years old = 120 milligrams daily

Recently, some experts have questioned whether the recommended daily intake should be raised. Others have recommended higher intake in some individuals, such as smokers, in whom an additional 35 milligrams daily has been recommended by some.

The upper limit of intake (UL) should not exceed 2,000 milligrams daily in men or women more than 18 years old (including pregnant or breastfeeding women).

Where do you STORE your FAT?

Where do you store your FAT?

Do you know the Waist and Hip Ratio Health Risks?

Many people worries about how heavy they are and the number they see on the scale, but the number on the scale does not tell you everything because you don’t know what is water, fat nor muscle (see me in the gym and I can measure you and tell the difference) and being skinny = no health sometimes, as someone who might look thin can have a high visceral fat (non-visible to the naked eyes) and suffer from similar problems as someone with high BMI.

Are you an Apple, Pear or even Avocado? R-P-T.co,.uk

Now, have you ever notice how some people can have big bellies but lean legs? How some people tend to store most of their fat in their thighs, hips, and butt? These are examples of fat distribution, which refers to where your body typically stores the fat, NO MATTER what your weight is!

This is important because where you store fat can be a predictor of health risk. Over weight (BMI over 25) is only one health risk factor. Where fat is stored on your body is another.

If you have fat stored around your waist as opposed to those who have excess fat in their hips and thighs, you have a HIGHER RISK of health problems even if your BMI is normal.

Waist measurement may be the best way to determine your progress, and it can take the emphasis off the number you see on the scale.

The waist-to-hip ratio is a common measure of fat distribution. Your ratio can help you track your weight loss progress, while also serving as a warning about your estimated health risk for problems related to being overweight, such as:

> Diabetes
> Stroke
> Heart Disease

In fact, a study reported in the American Journal of Clinical Nutrition that for some age groups, the waist-to-hip ratio is a better indicator of increased mortality risk than body mass index (BMI), which compares your height to your weight.

HOW TO MEASURE!

~ Step 1 - To measure your waist:
Place a tape measure around your bare abdomen at your natural waist (usually just above your belly button). Be sure the tape fits snugly but does not compress your skin. Place the tape parallel to the floor. Then relax, exhale and measure your waist.

~ Step 2 - To measure your hips:
Place a tape measure around the widest part of your buttocks.

~ Step 3 - Divide the calculation from step 1 by the calculation from step 2

Male	Female	Health Risk Based Solely on WHR
0.95 or below	0.80 or below	Low Risk
0.96 to 1.0	0.81 to 0.85	Moderate Risk
1.0+	0.85+	High Risk

Are you an Apple, Pear or an Avocado?

Pear Shape (Low Health Risk)
If you’re a pear shape, you tend to carry most of your weight in your hips, thighs and buttocks. Storing fat in your lower half is actually a healthier site for fat accumulation. Research shows that storing fat here may actually protect you against cardiovascular disease. In one study of 1,356 women, ages 60-85, Danish researchers found that those with excessive fat in the arms, legs, hips and buttocks had less atherosclerosis (hardening of the arteries) than those who stored most fat in their abdominal area and other central parts of the body.

Apple Shape (High Health Risk)
If you tend to carry weight in your abdominal area and upper torso, you’re an apple shape. People who are apple-shaped and tend to carry more weight around their waists (commonly referred to as a “pot belly”) are at a greater risk of lifestyle-related diseases such as heart disease and diabetes than pear-shaped people. However, a 2011 study of 220,000 people published in The Lancet did not find an increased risk.

Avocado Shape (Moderate Health Risk)
You may hear about apples and pears all the time, but what about people who don't fit into either category? The less common "avocado" shape is somewhere between an apple and a pear, with health risks higher than a pear-shaped person, but somewhat lower than a true apple-shaped person.

Your risk of chronic diseases such as diabetes and cardiovascular disease increases gradually with each inch (about 2.5 cm) your waist increases above 35 inches (89 cm) for women and 40 inches (102 cm) for men. And similarly, your risk increases as your waist/hip ratio increases above the goals listed above.

What is it about abdominal fat that makes it a strong marker of disease risk?

The fat surrounding the liver and other abdominal organs, so-called “visceral fat,” is very metabolically active. It releases fatty acids, inflammatory agents, and hormones that ultimately lead to higher LDL cholesterol, triglycerides, blood glucose, and blood pressure.

Improving Your Distribution
Once you know which body shape you have, and your potential level of risk, what can you do about it?

First, you have to accept that there is no way to change where your body stores fat, your genetics determine that. If you are an apple now, you will always be an apple, even if you lose a few extra pounds. Weight loss may not change your body shape, but it will reduce your size.

A well-rounded program of cardio and strength training, along with a healthy diet, will help with overall fat loss. No matter what your shape, maintaining a healthy weight will greatly reduce your risk of obesity-related illness.
