An animal study has shown that high doses of beta carotene supplements may increase the risk of precancerous changes in lung tissue. The changes were even more pronounced when the animals were exposed to cigarette smoke. For six months, researchers at Tufts University in Boston fed ferrets either a normal diet or a diet supplemented with high doses (equivalent to 30 mg per day in an adult) of

Results of a study published in the journal Neuron suggest that vitamin A affects cells in a region of the brain linked to learning and memory. Researchers created special genetically altered mice, known as knockout mice, which were missing two brain-specific receptors for the vitamin. Although the mice developed normally, compared to ordinary mice they performed poorly on standard intelligence

Elderly people may be able to reduce their risk of heart attack by eating fruit and vegetables rich in beta carotene, according to Dutch researchers. As part of The Rotterdam Study, the researchers followed the dietary and medical histories of 4802 people aged from 55 to 95 for four years. During this period 124 of the participants had heart attacks. Analysis of the results showed that those

Vitally important in protecting against birth defects, adequate folate is also important for breastfeeding women. Researchers from the University of Pennsylvania in the US enrolled 42 women in a double-blind, randomized trial. The women received a daily multivitamin and either a placebo or 1 mg of folic acid per day. At three and six months after birth the researchers measured folate stores in

Researchers analyzing the links between tomatoes and cancer risk have concluded that a high consumption decreases the risk. The researchers, from Harvard Medical School and Brigham and Women's Hospital in Boston reviewed 72 studies and found that 57 of these showed a link between increased tomato intake and lower cancer risk. The results of 35 of these were considered to be statistically

Thiamin deficiency seems to worsen the symptoms of malaria, according to researchers in the UK and Thailand. The researchers compared the levels of thiamin in the blood of 77 patients with malaria with those of 50 people who had no trace of the malaria parasite in their blood. The results showed that "12 of the 23 patients with severe malaria and 10 of the 54 patients with uncomplicated malaria

Results from the Nurses Health Study suggest that a high-fiber diet may not protect against colon cancer. This contrasts with several other studies that have shown reduced risk. The study involved 88 757 women, who were 34 to 59 years old and had no history of cancer, inflammatory bowel disease or familial polyposis. The women completed a dietary questionnaire in 1980. During a 16-year follow-up

Data from the Third National Health and Nutrition Examination Survey suggest that carotenoids may protect against the development of diabetes. Researchers from the Centers for Disease Control and Prevention in Atlanta, Georgia examined concentrations of alpha carotene, beta carotene, cryptoxanthin, lutein/zeaxanthin, and lycopene in 1010 people (aged from 40 to 74) with normal glucose tolerance.

The results of a study carried out by researchers at the University of Oxford in the UK suggest that folate supplements do not increase the risk of multiple births. Adequate folate intake during pregnancy has been shown to reduce the risk of neural tube defects such as spina bifida and many women take supplements. There has been some concern that supplements might increase the risk of having

Results from the Iowa Women's Health Study suggest that calcium, but not milk products or vitamin D, reduce the risk of death due to ischemic heart disease. The study involved 34 486 postmenopausal Iowa women 55 to 69 years old and without a history of ischemic heart disease who completed a dietary questionnaire in 1986. Through 1994, there were 387 deaths due to ischemic heart disease.

A recent US study suggests that people who drink tea are less likely to suffer a heart attack. Researchers investigated the effects of caffeinated coffee, decaffeinated coffee and black tea on heart attack risk in 680 people, half of whom had suffered a heart attack. The results showed that those who drank one or more cups of tea a day had a 44 per cent reduced risk of heart attack compared

Calcium supplements may help stop the reappearance of colon polyps. Polyps are abnormal growths in the colon that are usually benign but may turn cancerous. They are often removed to prevent the development of cancer. In a study reported in the New England Journal of Medicine, doctors studied 930 patients, with an average age of 61 years, who had had one or more polyps removed from the large

The results of a Swedish study add further weight to the evidence that diets high in beta carotene can reduce breast cancer risk. Of the 644 women who took part in the study, 273 had been diagnosed with breast cancer. The women were asked to recall details about their diets at various times in their lives. The results showed that women whose diets had included beta carotene for 20 years or more

The vitamin D deficiency disease, rickets has been reported in four children in the US, according to the researchers writing in the Journal of the American College of Nutrition. The children were between the ages of four and 24 months and all lived in suburban America. Experts believed that rickets was eliminated from the US with the introduction of vitamin D fortified milk. However, children

The results of a large study carried out in India suggest that zinc deficiency may increase the risk of heart disease and diabetes. Researchers examined zinc intake in 3575 rural and urban adults in northern India. The results showed that those who consumed less than 7 mg per day had an increased risk of diabetes. Urban residents also showed higher rates of heart disease. Journal of the

High intake of vitamin A leads to reduced bone density and increases the risk of bone fractures and osteoporosis, according to Swedish researchers. In the first part of the study, researchers measured the bone density of 175 women, aged from 28 to 74. The women were asked to record everything they ate over a typical week and the vitamin A content was calculated. The results showed that women

A supplement that combines folate and vitamin B12 may be more beneficial for the heart than folate alone, according to a recent study by researchers at the University of Bonn in Germany. Both folate and vitamin B12 have been shown to reduce homocysteine levels, protecting the heart and blood vessels from the damaging effects of this amino acid.

A solution of glucose, potassium and insulin has been shown to be effective in reducing deaths from heart attack, according to a study carried out in six Latin American countries. This treatment was originally introduced in the early 1960s but was subsequently abandoned due to doubts about its effectiveness. The study involved over 400 patients with suspected heart attack.

Results from the Nurses Health Study suggest that women who frequently include nuts in their diet have a reduced risk of coronary heart disease. The study involved over 80 000 women aged from 34 to 59 who had not been diagnosed with any kind of heart disease. In 1976, at the start of the study, researchers collected detailed information on the medical histories and lifestyles of 121 700 nurses.
