Grape Juice Has the Same Benefits as Red Wine

Drinking Grape Juice Gives Same Protective Benefits as Drinking Red Wine

The cardiovascular benefits of a daily glass of red wine are well known to most people. Non-alcohol drinkers have often wondered if they could have the same benefits from wine's unfermented sibling - the grapes.

Grape juice may not provide much buzz, but you can still toast to good health when it comes to its ability to avert heart disease.

The substances believed to provide much of red wine's heart benefits - resveratrol and flavonoids - are also found in grape juice, especially the variety made from red and dark purple Concord grapes.

Independent studies have found that like alcohol, grape juice can reduce the risk of blood clots and prevent LDL, or bad cholesterol, from sticking to coronary arteries, among other cardiac benefits.

One study, conducted by scientists at the University of Wisconsin and published in the journal Circulation, looked at the effects of two servings of Concord grape juice a day in 15 people with coronary artery disease. After two weeks, the subjects had improved blood flow and reduced oxidation of LDL. Oxidised LDL can damage arteries.

Other studies in humans and animals, including one last year in the journal Atherosclerosis, have shown that daily consumption of grape juice may lower blood pressure and cholesterol levels. Beware though, some varieties of grape juice have added sugars and artificial ingredients.

The bottom line is simply this: the studies have indicated that there are some kinds of grape juice may provide the cardiac benefits of red wine.

Types of Calcium Supplements

What Type of Calcium Supplement Should You Be Taking?

Most calcium supplements, if the right dose is taken, are adequate for our daily requirements. There are a few general factors that affect the absorption of calcium supplements.

The first factor is the time taken for the supplements to disintegrate in the gastro-intestinal tract. If the supplement is not properly disintegrated, absorption will be lowered.

Secondly, there are different grades of calcium and inactive ingredients that go into the making of a supplement.

Pharmaceutical grade ingredients make for better quality products. Generally, the premium brands use better raw materials and have better controlled manufacturing processes to ensure proper supplement disintegration.

Caltrate is the brand name of a calcium supplement. Many supplements contain calcium carbonate as their principal ingredient. To improve absorption of calcium carbonate, calcium is usually taken with food.

You can also take calcium carbonate in divided doses, instead of one single large dose to allow for better absorption.

Calcium carbonate is commonly used because it is readily available and inexpensive.

Calcium L-threonate and calcium L-aspartate are other calcium compounds used in some of the latest calcium supplements. They are chelated calcium which helps to improve absorption.

Some studies suggest that the absorption of calcium from milk does not differ too greatly from the other calcium salts.

Remember that adequate vitamin D is neccessary for the absorption of calcium.
