Vitamin A

Posted by:

Vitamin A is a Fat soluble Vitamin. It is stored in the Liver. It helps vision and keeps the body tissues healthy, the skin and mucous membranes and aids cell growth. It is part of the Antioxidant vitamin combo of A,C and E.

yellow fruitsOften in skin care products you read about an ingredient called Retinol, this is a form of Vitamin A found in foods of animal origin. Pro-Vitamin A or better known as Beta-carotene is found in fruits and vegetables particularly those which are yellow.

The Beto-carotene is responsible for the pigment in these brightly coloured fruit and vegetables. If consumed in large enough quantities it can turn your skin this colour too!! It is called Carotenosis and this occurred in the late 90’s when children consumed very large volumes of a popular children’s drink it also occurs if you drink a lot of carrot or orange juice. Tanning tablets too work on this principle, it can be harmless in most cases and normal skin colouring will return in a few weeks, however you may experience an upset tummy and flatulence if you consume beta-carotene in these large amounts.

The sources of this Vitamin come from both animals and plants. In animals the sources are from fish liver oil i.e cod liver oil, Liver and eggs and dairy produce. Many margerines are fortified. Vitamin A is a fat soluble vitamin and some of it is lost when milk for example is skimmed.

Liver is an excellent source of Vitmin A, it is a food to keep limited to maybe once a fortnight as it can be a source of medications, hormones or antibiotics that the animal has been given through its life.

Vitamin C and Vitamin D.

Posted by:

Continuing my brief look at some of the Vitamins, here I’m taking a quick look at Vitamins C and D….

 

Vitamin D.

Latitude, the lessening of sunshine hours in winterand the consumption of more and more processed foods; our Vitamin D (alongwith other Nutrients) can get neglected. The sun is our best source, which can be a tad unfortunate when you live in the more Northerly Latitudes! Vitamin D is a fat soluble Vitamin which means the body can store it in our fat stores and can use this supply when it is scarce – as in winter.   It can also be supplemented (under supervision as it is a fat soluble vitamin it can be toxic if too high a dose is taken) or, it can be incorporated into the diet which is much safer to do. Sun exposure is the safest way as long as it is done within sensible guidelines for a short period without sunscreen for example 15-20 minutes uncovered should be sufficient.

butterflyVitamin D is intrinsic for our immunity and our bone health as it helps you absorb Calcium properly. Vitamin D2 is the variant found in foods whilst D3 is found in the sunshine.

Many countries have enriched foods such as milk and cereal with Vitamin D. Oily fish is also a great source so fish such as Tuna, Mackerel no more than a couple times a week, are recommended. Egg yolks too are a source and of course fish oil supplements contain this. Be aware if taking multiple supplements without guidance that you’re Vitamin D does not exceed recommended limits.

 

Vitamin C.

A water –soluble Vitamin so it is excreted out in the urine and needs topped up daily. It is the least stable vitamin and is easily destroyed by cooking, which is why gently steaming veg is a good way to keep levels intact as is eating plenty of raw fruit and brightly coloured salad veg.

It is an Antioxidant. It also helps the absorption of Iron to be more efficient. Helps with the formation of Collagen and is essential for growth and repair of tissue and by extension wound healing.

Regular drinkers and smokers can easily run low on this Vitamin as both toxins deplete levels. People with Wounds, Burns, Pneumonia, TB, and People recovering from surgery may all need extra to encourage the healing process.

Deficiency leads to Scurvy, Joint Pain, Poor wound healing, Loose Teeth and Swollen gums. Bruising and little Red Spots on the Skin, Fatigue and sometimes Depression are among the delights encountered if your levels are low.

Vitamin C reduces the Histamine levels in the body which can help reduce symptoms and the duration of a cold. But it cannot cure a cold. Sorry!!
