Good Vitamin Supplement

Good Vitamin Supplement

A healthy immunity system plays a major role in defending and preventingdisease, illness, and stress, especially during the winter season. Winter is the main season that actually tests your immune system’s strength, though it is important that you keep your immunity levels strong throughout the year.

Reasons for Natural Weakness in Immune System during thewinter

As the winter season approaches, the natural defense system can be boosted, thereby assisting to keep off common winter diseases like flu, cold, and infections. This can be done by increasing the vitamins and antioxidants intake, thus strengthening the immunity system and assisting the body to fight against the bad viruses and bacteria that can cause illness. Here’s some advice as to how you can support your immune system in winter with a good vitamin supplement. So, let’s start by taking a look at the vitamins that you should be consuming in the run up to winter.

It’s Not About Consuming a Particular Vitamin!

It’s not that a single vitamin is essential for boosting the immune system of the body. A wide variety of vitamins as well as nutrients work together to fight the infections, though, these vitamins have a major role.

Benefits of Vitamin A

Vitamin A is the immune system’s defensive line and it keeps germs and infections from entering the bodies. It is responsible for keeping the mucous membranes lining the nose, mouth, and throat moist and soft so that they can trap the germs, ceasing their infiltration. Moreover, this vitamin helps in generating enzymes that look out for germs that manage to enter the body and kill them. People deficient in this vitamin can consume vitamin A rich food sources like carrot, sweet potatoes, liver, dried herbs, lettuce, dried apricots, and cantaloupe.

Vitamin B Boosts Up Your Energy Level

Vitamin B usually boosts the energy levels, thereby boosting the immunity system. These vitamins are available in the form of vitamin supplements, including B6, B12, and foliate. Studies have revealed that vitamin B6 can also strengthen the immunity system to a great extent.

Vitamin C Generates Antibodies and WBC

Vitamin C is equally important for enhancing the immunity system of the body. It assists the body to generate the white blood cells, antibodies, and anti-stress hormones, which are all needed for fighting the infections. This class of vitamin is a powerful antioxidant that kills fungi, bacteria, parasites, and viruses; it neutralizes the harmful bacteria and environmental toxins, while removing the toxic metals. To increase the vitamin C level in your body, you can consume food sources rich in this particular vitamin like guavas, dark leafy greens, cauliflower, broccoli, papayas, strawberries, kiwi, bell peppers, melons, tomatoes, and citrus fruits.

Role of Vitamin D

One of the most essential vitamins for immune functioning is vitamin D. Our bodies are made naturally in a way that they can increase the vitamin D reserves during the summer season so that it can be released slowly during the winter. We are moving near to deficiency levels in western communities and our immunity systems are not receiving the needed support as such. Thus, for several people, by improving their vitamin D levels before it gets very cold, we can make our bodies ready to prevent the illnesses and viruses that are common during the colder months. Few of the food sources rich in vitamin D include eggs, cod-liver oil, salmon, oysters, fish, soymilk, orange juice, and cereals. Vitamin D can also be obtained from safe exposure to sun.

How Does Vitamin E Help You?

Vitamin E also enhances the immunity system by generating an immune protein- interleukin-2 that kills viruses, bacteria, and even cancer cells. This particular protein is generated in the body when the body thinks that it has been invaded by infection-causing germs and it assists the white blood cells to increase and fight the diseases.

Few sources of food items rich in vitamin E include paprika, almonds, sunflower seeds, peanuts, and cooked spinach.

Zinc is another nutrient, which several people may find to be deficient in, particularly in the poorer and developing nations. Food sources for zinc include milk products, whole grains, oysters, red meat, and poultry. But, if your diet lacks zinc food sources, you may have to replace them with vitamins.

In a Nutshell

Now that you’ve understood all vitamins have one or the other role in boosting the immunity system, equal intake of all these vitamins is essential to lead a healthy life. By consuming natural food rich in vitamins, antioxidants, and other nutrients needed for a strong immunity system, you can get your body ready to fight off the infections during the winter. There are also vitamin supplements available in the health stores.

Joshua Jacksonis a strong supporter of green living, and staying healthy with natural supplements. He strongly recommends consumption of natural Vitamin Supplements during the winter season and avoiding the common diseases due to natural weakness caused in the immunity levels.

The Health Benefits of Grapefruits http://health-club.org/health-benefits-grapefruits http://health-club.org/health-benefits-grapefruits#comments Thu, 24 May 2012 06:41:37 +0000 Healthy Eating http://health-club.org/?p=2266

The Health Benefits of Grapefruits

 

Health Benefits of Grapefruits

Health Benefits of Grapefruits

 

Grapefruit is a type of fruit that is related to the family of oranges, which has segmented parts with a clean, juicy flesh and citrus or tangy flavor. Grapefruit literally means fruit of paradise, which owes it to its vast health benefits. Grapefruits differ on their internal colors such as white, pink or red. All the variations of grapefruit have the same health benefits, but according to the World’s Healthiest Foods, the red variation of grape fruit contains the highest benefits.

The health benefits of grapefruit are based on its components such as fiber and phytonutrients. However, if you are taking medications such as statins, better consult your physician before taking grapefruit because it causes drug interactions. Nevertheless, those who are not taking medications that may possibly interact with grapefruit may have its benefits safely. The health benefits of Grapefruit include:

Improves digestive functions

The high dietary fiber content of grapefruit makes it a good remedy for improved bowel elimination. It also improves the digestion; thereby absorbing most of the nutrients you take in.

Prevents infections and diseases

Grapefruit contains high amounts of vitamin C, which helps the body to fight infections by strengthening the collagen matrix of the cells.

Contains antioxidants

Grapefruit is also an excellent source of antioxidants, which prevents cellular oxidative stress that leads to various diseases. This function also reduces the amount of cholesterol in the body that reduces the risk for cardiovascular diseases such as hypertension, heart attack and stroke. The red variation of grapefruit tends to have the highest antioxidant properties.

Prevents development of cancer

Grapefruit contains high amounts of carotenoids, which are plant compounds that are able to prevent certain types of diseases. Specifically, the red and pink variations of grapefruit contain high amounts of lycopene, which has chemoprotective properties. This prevents the damage to the cells that may prevent cancers such as prostate cancer.

Detoxifies the body

Grapefruit also contains another phytonutrient called limonoids. Limonoids are special compounds that make carcinogens and other toxins in the body to become more water soluble; thereby making them easier to flush out of the system.

Contains high amounts of pectin

Pectin is a natural fiber that helps slow down atherosclerosis or the accumulation of cholesterol and lipids in the walls of the blood vessels. Pectin may reduce the level of low density lipoproteins or the bad cholesterol as well as harmful triglycerides that tend to attach to the blood vessel walls. The white and red variations of grapefruit may have different levels of antioxidant properties, but both have equal efficacy in reducing the cholesterol and lipid levels.

Includes high amounts of vitamins and minerals

Grapefruit is a rich source of vitamin A, which is important for normal vision. A half of a grapefruit may deliver up to 6.4% of the recommended daily allowance for vitamin A. In addition, grapefruit also contains high amounts of B vitamins essential for metabolism and cellular functioning. Furthermore, grapefruit also contains potassium, which is essential for normal contractility of the heart muscles and smooth muscles.

Next time you buy grapefruit, choose the colored variations in order to have more of its benefits.

Vitamin C – description http://health-club.org/vitamin-c http://health-club.org/vitamin-c#comments Wed, 20 Apr 2011 11:55:05 +0000 Healthy Eating http://health-club.org/?p=28

What is vitamin C?
Vitamin C (also known as ascorbic acid) is abundant in vegetables and fruits. A water-soluble vitamin and powerful antioxidant, it helps the body form and maintain connective tissue, including bones, blood vessels, and skin.

Why is vitamin C necessary?

Many do not know all of the facts on vitamin C, which helps to repair and regenerate tissues, protect against heart disease, aid in the absorption of iron, prevent scurvy, and decrease total and LDL (“bad”) cholesterol and triglycerides. Research indicates that vitamin C may help protect against a variety of cancers by combating free radicals, and helping neutralize the effects of nitrites (preservatives found in some packaged foods that may cause cancer). Supplemental vitamin C may also lessen the duration and symptoms of a common cold; help delay or prevent cataracts; and support healthy immune function.

What are the signs of a deficiency?
The facts on vitamin C tell us that deficiency symptoms include fatigue, muscle weakness, joint and muscle aches, bleeding gums, and leg rashes. Prolonged deficiency can cause scurvy, a rare but potentially severe illness.

How much, and what kind, does an adult need?
According to the National Institutes of Health (NIH), the recommended daily intake for adults is 90 mg per day for men and 75mg for women (85 mg during pregnancy, 120 mg while breastfeeding). Smokers may benefit from a higher intake. Dr. Weil recommends taking 250 mg of vitamin C each day, or higher doses – greater than 1,000 mg per day – for additional protection against the oxidative effects of air pollution and smoke.

How much does a child need?
NIH recommends Adequate Intakes (AIs) for infants between 0 and 6 months at 40 mg per day, and for infants 7 to12 months old at 50 mg per day. The U.S. Dietary Reference Intakes (DRIs) for children 1 to 3 years old is 15 mg per day; for children 4 to 8 years of age, 25 mg; and children 9 to 13 years old, 45 mg per day. Males between 14 to 18 years of age should take 75 mg per day; females, 65 mg.

How do you get enough vitamin C from foods?
Vitamin C is easy to get through foods, as many fruits (especially citrus) and vegetables contain vitamin C. Good sources include: Apples, asparagus, berries, broccoli, cabbage, melon (cantaloupe, honeydew, watermelon), cauliflower, citrus fruits (lemons, oranges), kiwi, fortified foods (breads, grains, cereal), dark leafy greens (kale, spinach), peppers (especially red bell peppers,which have among the highest per-serving vitamin C content), potatoes, and tomatoes.

Are there any risks associated with too much vitamin C?
When obtained from food sources and supplements in the recommended dosages, vitamin C is generally regarded as safe. Side effects are rarely reported, but include nausea, vomiting, heartburn, abdominal cramps, and headache. High doses of vitamin C (greater than 2,000 mg/day) may contribute to the formation of kidney stones, as well as cause severe diarrhea, nausea, and gastritis.

Are there any other special considerations?
Adverse affects may occur between vitamin C and acetaminophen, antacids that contain aluminum, aspirin, and Warfarin. Nicotine products, oral contraceptives/estrogens, tetracyclines and barbiturates may decrease the effects of vitamin C.

Facts on vitamin C show that it may increase absorption of iron and lutein, and some evidence suggests that large doses of supplemental vitamin C may interfere with the absorption and metabolism of vitamin B12 found in food.
