A Closer Look At Water
Water-soluble vitamins are packed into the watery portions of the foods you eat. They are absorbed directly into the bloodstream as food is broken down during digestion or as a supplement dissolves.
Because much of your body consists of water, many of the water-soluble vitamins circulate easily in your body. Your kidneys continuously regulate levels of water-soluble vitamins, shunting excesses out of the body in your urine.

Food Sources Of Iodine
We only need a very small amount of iodine in our diet. Iodine is found naturally in foods such as:
- dairy products
- some vegetables.
Iodine can also be found in iodised salt. All bought breads in Australia are fortified with iodised salt.
You are likely to be getting enough iodine through your diet. However, if you are deficient and need to take a supplement, be guided by your doctor. Too much iodine can be harmful, especially if you have an underlying thyroid disorder.

Their popularity has increased rapidly in the past few decades .
Some people believe that multivitamins can improve health, compensate for poor eating habits, and even reduce your risk of developing chronic diseases.
This article examines the scientific evidence behind multivitamins.

Food Sources Of Vitamin D

Treatment options include improved sunlight exposure, diet, exercise, vitamin and mineral supplements.
If you are concerned about vitamin D levels, see your GP. Your GP may recommend vitamin D supplements, which should be taken strictly as directed.
History Of Promotional Marketing
Once discovered, vitamins were actively promoted in articles and advertisements in McCall’s, Good Housekeeping, and other media outlets. Marketers enthusiastically promoted cod-liver oil, a source of vitamin D, as “bottled sunshine”, and bananas as a “natural vitality food”. They promoted foods such as yeast cakes, a source of B vitamins, on the basis of scientifically determined nutritional value, rather than taste or appearance. In 1942, when flour enrichment with nicotinic acid began, a headline in the popular press said “Tobacco in Your Bread.” In response, the Council on Foods and Nutrition of the American Medical Association approved of the Food and Nutrition Board‘s new names niacin and niacin amide for use primarily by non-scientists. It was thought appropriate to choose a name to dissociate nicotinic acid from nicotine, to avoid the perception that vitamins or niacin-rich food contains nicotine, or that cigarettes contain vitamins. The resulting name niacin was derived from nicotinic acid + vitamin. Researchers also focused on the need to ensure adequate nutrition, especially to compensate for what was lost in the manufacture of processed foods.

Different Types Of Vitamin And Their Health Benefits
What is food it is regarded as one of the basic units of life which contributes to keeping us alive. It provides nutrition in form of certain elements like Vitamins, Minerals, Amino acids, trace meats, moisture, protein, carbohydrates, fibres and many more. Each of them is classified with several subparts. Here, we will be discussing Vitamins and its types with the functions and health benefits.
How Much Vitamin D Do I Need
From about late March/early April to the end of September, the majority of people should be able to make all the vitamin D they need from sunlight on their skin.
Children from the age of 1 year and adults need 10 micrograms of vitamin D a day. This includes pregnant and breastfeeding women, and people at risk of vitamin D deficiency.
Babies up to the age of 1 year need 8.5 to 10 micrograms of vitamin D a day.
A microgram is 1,000 times smaller than a milligram . The word microgram is sometimes written with the Greek symbol followed by the letter g .
Sometimes the amount of vitamin D is expressed as International Units . 1 microgram of vitamin D is equal to 40 IU. So 10 micrograms of vitamin D is equal to 400 IU.

How To Buy Vitamins
Supplements are not regulated by the U.S. Food & Drug Administration or USDA. So how do you know youre getting safe supplements?
Patton recommends doing the following before buying:
- Consult your doctor. Before adding any supplements, make sure you talk to your doctor to make sure you need them and that they wont interact with any medications.
- Look for third-party testing. Some companies will send their products to an outside company to verify that the ingredients are accurate.
- Look for the USP seal. The United States Pharmacopeia is an independent, nonprofit organization whose goal is to supply safe, quality products.
- Consider ingredients. Stick with the basics. Vitamins with added ingredients or claims arent necessary and can cause side effects.
So while supplements can be helpful, be mindful of your diet and what you eat. Dont use supplements to replace healthy eating, says Patton.
Cutting Down On Free Sugar
Foods that contain free sugars aren’t required as part of a healthy balanced diet, so you should try to eat these less often and in smaller amounts.
To do this, use food labels to choose items that are lower in sugar and swap:
- sugary breakfast cereals for plain cereals – such as plain porridge, wholewheat biscuit cereals, shredded wholewheat or no added sugar muesli
- flavoured or corner-style yoghurts for low fat, lower sugar yoghurts, adding fresh fruit for variety
- sugary drinks for water, lower fat milk, sugar-free drinks or tea and coffee
Sugary drinks account for a surprisingly large proportion of the daily sugar intake of both children and adults. Almost a third of the free sugars consumed by 11 to 18 year olds come from soft drinks.
Cereal bars often contain high levels of free sugars too, so remember to check the label.

Vitamins Hang Out In Water And Fat
There are two types of vitamins: fat soluble and water soluble.
When you eat foods that contain fat-soluble vitamins, the vitamins are stored in the fat tissues in your body and in your liver. They wait around in your body fat until your body needs them.
Fat-soluble vitamins are happy to stay stored in your body for a long time. Then, when it’s time for them to be used, special carriers in your body take them to where they’re needed. Vitamins A, D, E, and K are all fat-soluble vitamins.
Water-soluble vitamins are different. These vitamins dissolve in water. When you eat foods that have water-soluble vitamins, the vitamins are not stored in your body. Instead, they travel through your bloodstream. Whatever your body doesn’t use comes out when you urinate .
So water-soluble vitamins need to be replaced often because they don’t stick around! This crowd of vitamins includes vitamin C and the big group of B vitamins B1 , B2 , niacin, B6 , folic acid, B12 , biotin, and pantothenic acid.
Advice For Adults And Children Over 4 Years Old
During the autumn and winter, you need to get vitamin D from your diet because the sun is not strong enough for the body to make vitamin D.
But since it’s difficult for people to get enough vitamin D from food alone, everyone should consider taking a daily supplement containing 10 micrograms of vitamin D during the autumn and winter.
Between late March/early April to the end of September, most people can make all the vitamin D they need through sunlight on their skin and from a balanced diet.
You may choose not to take a vitamin D supplement during these months.

Vitamin And Mineral Deficiencies And Supplements
The fat-soluble vitamins A, D, E and K can be locked away in the liver and body fat, and stored for a long time. The water-soluble vitamins, including B-complex and vitamin C, are mostly only stored for a shorter period.A vitamin deficiency takes weeks or months before it will affect your health. For instance, it would take months of no vitamin C before you developed scurvy.
Vitamin and mineral supplements may be recommended in certain circumstances to correct vitamin and mineral deficiencies such as folate for women who are pregnant or planning a pregnancy. Others who may be at risk of a vitamin or mineral deficiency include:
- pregnant women and women who are breastfeeding
