Along with many other super-foods, blueberries have recently been highly spoken of. Featured in magazines and on TV shows, are these really a wonder drug that can keep you looking and feeling young? Or are they just a load of hype once more?
Like many other super-foods, blueberries contain flavanoids which are powerful antioxidants that are purported to have anti-cancer properties. Studies have been done, mostly on animals, that show other great health benefits such as reversal of lost coordination, improved memory, increased lifespan and more. It is thought that it may even be able to protect against or slow down the onslaught of Alzheimer’s Disease.
What Is Concrete?
Most studies have been done on animals and it is difficult to say whether they would have the same benefits on humans. However, there are some things about blueberries that we can definitely confirm.
For example, blueberries definitely have a high antioxidant capacity. This is something that has been measured many times in a laboratory setting. In one study, a researcher for the US Department of Agriculture confirmed this by measuring the total antioxidant capacity (TAC) and the cellular antioxidant activity (CAA) against other berries.
Wild blueberries outscore most other blueberries including cranberries, blackberries, raspberries, strawberries as well as other fruits such as pomegranates and sweet cherries. It should be noted that cultivated blueberries had a much lower antioxidant activity/capability. Therefore, you should always look for wild ones wherever you can.
All berries, blueberries included, also contain high levels of anthocyanins and it has been known for many years that these pigments have a wide variety of health benefits. Most research has been done using black raspberry anthocyanins and numerous conclusive studies have been completed. For example, these anthocyanins have been shown to inhibit tumour cells. Since 2007, they have been the subject of human trials.
Although these studies used black raspberries (partly due to their wide availability in North America), it is probably safe to assume that these benefits are at least partly enjoyed in all other berries containing anthocyanins, including blueberries.
Other Benefits
The antioxidant and probable anti-cancer benefits of blueberries are clear to see – but what of the other health benefits? One study published in Experimental Neurology and carried out on rats looked into the effectiveness of feeding with a blueberry diet and then observing activity after an induced stroke. The study found that aptosis (a type of cell death) was reduced in the brains of the rats after stroke in those that had eaten the diet compared to those that had eaten the control (normal) diet. Therefore, blueberries can be seen to have a neuroprotective effect.
The Best Blueberries
Always try to obtain wild, organic blueberries wherever you can. Cultivated blueberries simply do not have the same benefits as wild ones. If all you can find are cultivated ones then you are better off eating a variety of berries instead as you will get the same benefits and enjoy a more varied diet.
Inspect your blueberries before buying them. A good supplier should be checking for mould and other afflictions and making sure that delivered fruits are not contaminated.
Blueberry extract supplements are available but they are pretty pointless because they tend to contain low amounts of anthocyanins and you would have to take of the order of 10 or 20 pills daily to compare to a good dose of fresh ones (e.g. one cup). Furthermore, they are also more expensive than eating the fruit directly which is actually fairly cheap.
I recommend eating half a cup to a full cup of blueberries every day. They can stain your mouth if eaten individually but you can avoid this by blending them into a drink.
The American Psychological Association recently conducted an annual survey of 7,000 Americans. The results show just in the past five months, anxiety about the economy has jumped from 66 percent to 80 percent. Americans are stressed about their personal finances and the economy, and to cope with stress, the survey found that up to 48 percent said they have overeaten or consumed fatty, unhealthy food.
Traditional Chinese Medicine includes the use of mushrooms. However, the medicinal properties of mushrooms have only been studied in the West for the past 30 years or so. Nevertheless, cancer drugs have been patented as a direct result of mushroom research.
Dried fruits and vegetables are high in fiber and carbohydrates and low in fat, which is good since part of the food pyramid says that we need to eat fruit on a daily basis. The only down side to dried frufits is that they are calorie dense compared to fresh fruit, so the recommended serving size is half that of fresh fruit.
Asparagus is a green vegetable with spear shaped stalks. It grows best in sandy soil and is part of the Lily family along with garlic, onions and leeks. It has a high content of folic acid, potassium, thiamin, and fiber. Asparagus is a good source for vitamins A, B6 and C.
