Myths and facts on nutrition topics

Food Today looks at some common myths about acidic foods, fluids and sugar

Myth: Eating acidic foods, like oranges, disturbs the acid/alkaline balance in the body.

Fact: The body works to maintain an acid to alkaline balance at all times through specific buffering systems. Even the slightest alteration to blood alkalinity can adversely affect vital body functions needed to sustain life. Luckily we have many systems in place to ensure this is so, including the lungs and kidneys. In healthy individuals, what you eat is not likely to greatly affect the balance. Oranges and other "acidic" fruits and juices are a great source of vitamin C and plant nutrients, so keep eating them!

Myth: You should "feed a cold and starve a fever".

Fact: You do not need to do either. Instead it's better to follow your appetite, although if you are sweating a lot with a fever then it is really important to increase your fluid intake to avoid becoming dehydrated. If you feel like eating, have some protein food such as fish, chicken, meat or pulse vegetables. The stress of illness can increase protein demands. Other important nutrients needed for the production of "germ-gobbling" cells in the immune system are zinc (in seafood and red meat) plus folic acid and pro-vitamin A (beta carotene) in broccoli, spinach and carrots.

Myth: To avoid indigestion, fluids should not be taken with meals.

Fact: Drinking plain water with meals should not be a problem. If you are prone to bloating and indigestion it is probably wise to avoid sparkling water or other carbonated drinks when eating because they may add to the gas in your digestive system. Otherwise the best advice is to eat slowly and not talk with your mouth full to decrease the amount of air swallowed and lessen the chances of bloating.

Myth: Sugar is addictive

Fact: This is just not true. An addictive substance is one that causes the body to require more and more of it to satisfy its needs and that leads to unpleasant symptoms of withdrawal when it is not available. While people may enjoy and want sweet foods, it is unlikely that you actually need bigger and bigger portions to meet needs and will suffer real physical withdrawal if they become unavailable. The body is not actually able to tell the difference between sugar in a piece of fruit, such as an apple, or table sugar. It is unlikely that people would ever believe they were addicted to, or suffering withdrawal symptoms from, apples should their daily serving be withdrawn.

Myth: Cold pressed, extra virgin olive oil is better for you than other oils because it contains less fat.

Fact: "Cold-pressed" refers to the method of production of the oil, which involves minimal processing at low temperatures.

All oils supply the same amount of fat, gram for gram, whatever their source. Like all fats, olive oil also supplies 9 calories (37 kilojoules) per gram and so should be consumed in moderation.

The health benefit of unsaturated oils, (such as olive oil, seed oils, other monounsaturated oils and polyunsaturated oils) is that they appear to help keep levels of cholesterol within the normal range in the blood. This makes them a good substitute for saturated fats.

Is too much soy bad for men?

While soy may be beneficial to women in a variety of ways, research in monkeys suggests that it could have an adverse effect on the behavior of men, according to researchers from Wake Forest University Baptist Medical Center. Reporting in the current issue of the scientific journal Hormones and Behavior, the researchers found that in male monkeys, "long-term consumption of a diet rich in soy isoflavones can have marked influences on patterns of aggression and social behavior." Isoflavones are a naturally occurring plant estrogen in soy protein. "Although considerable attention has been directed at the potentially beneficial effects of isoflavones in reducing the risk of various cancers, osteoporosis, cardiovascular disease and postmenopausal symptoms, less effort has been invested in characterizing neurobehavioral effects," according to the study.

Dietary modification could be a simple way to reduce the risk of stroke

Dietary modification could be a simple way to reduce the risk of stroke say researchers. The research shows a diet that consists of meats, refined grains and desserts is associated with a greater risk for stroke than a diet of fruits, vegetables, fish, legumes and whole grains. The study included dietary information on 71,768 female nurses between 38 and 63 years old. The women had no history of heart disease or diabetes. They completed questionnaires about their diet every few years for 14 years. Researchers tracked how many of the women had a stroke and then compared their diets. They rated the women's diets based on if they ate more of a Western diet or a prudent diet. During the follow-up, 791 women in the study had had a stroke. It was found that women who ate a Western diet vs. a prudent diet had a higher risk of developing a stroke . They say those who had the highest scores for a Western diet, meaning they mainly ate meat, refined grains and sweets, had a more than 50...

Patient wins right to stop doctors withdrawing food and drink when he can no longer speak

Leslie Burke, who has a degenerative brain condition (cerebellar ataxia), was concerned that doctors may one day withdraw food and drink when he could no longer speak. He has won a high court ruling which says the doctors cannot do that. Leslie wants to go on living for as long as he can, even when he loses his ability to communicate his wishes to people around him. According to UK General Medical Council guidance on providing artificial nutrition, Leslie thought there might be situations in which life saving food and drink could be withdrawn, even if this went against his wishes. If his situation got so that he could not speak, the present guidance could allow doctors to remove food and drink. Now the General Medical Council will have to re-write the guidance as a result of the new High Court ruling. This new ruling applies to all terminally ill patients and also patients who lose the ability to speak and communicate their wishes to doctors. The General Medical Council can appea...
