The study's findings suggest that with lifestyle changes, African Americans can prevent hypertension and related diseases.
Children and adolescents with celiac disease have significantly lower lumbar spine and whole-body bone mineral density than healthy peers. A gluten-free diet rapidly increases BMD, leading to complete recovery of bone mineralization, emphasizing the need for early diagnosis and treatment.
Recent studies indicate that genetic variants, such as apoE4 and LDL subclass pattern B, can significantly impact an individual's cholesterol response to a low-fat diet. Individuals with these genetic predispositions may require specific dietary modifications to effectively manage their cholesterol levels and heart disease risk.
A study of 80,082 female nurses over 14 years found increased folate and vitamin B-6 intake to be predictive of reduced coronary heart disease risk. The researchers suggest that lower blood homocysteine levels may account for the protection offered by these vitamins.
A recent study by Ohio State University found that mild iron deficiency weakens bones and increases the risk of fractures in laboratory rats. The researchers also discovered that even minor iron deficiency can lead to lower bone density, making it more likely for bones to break.
The Vegetarian Diet Pyramid offers a well-balanced ovo-lacto vegetarian diet plan emphasizing fruits, vegetables, whole grains, and legumes. The pyramid recommends daily exercise and water intake, while optional foods include eggs and sweets.
A high-protein, low-calorie diet has been shown to help obese hospital patients maintain stable blood sugar levels and burn body fat without compromising their health. The diet allowed patients to avoid diabetes and hyperglycemia, while also reducing the risk of post-operative infections.
Researchers found that omega-3 fatty acids in fish oil reduced cholesterol accumulation in the liver and arteries, despite increasing LDL cholesterol and decreasing HDL cholesterol. The findings suggest that omega-3 fatty acids may exert protection from atherosclerosis through alterations in tissue cholesterol metabolism.
Research suggests that a stable fish diet can significantly lower lipoprotein (a) levels, a blood fat linked to increased heart attack risk. The study found a 40% median Lp(a) difference between groups, with fish-eaters having lower levels of the 'bad' cholesterol.
A major European study found that an antioxidant compound called lycopene in tomato sauce appears to have a protective effect against heart attacks. The study showed men with high lycopene consumption had about half the risk of heart attack compared to those with low lycopene consumption.
The American Heart Association recommends a daily fiber intake of 25-30 grams from whole grains, legumes, vegetables, and fruits to lower blood cholesterol and reduce the risk of heart disease. A diet rich in these foods can also aid in weight control and improve overall nutritional health.
A recent study published in The New England Journal of Medicine found that a diet rich in fruits, vegetables, and low-fat dairy products can significantly lower blood pressure. Among participants with high-normal or stage 1-mild hypertension, the DASH combination diet reduced systolic and diastolic blood pressure by an average of 3.5 m...
Research suggests that dietary levels of nutrients during formative months and years are important determinants of blood pressure. Studies found that children who consumed more calcium and fiber had lower diastolic blood pressure, while eating more fat was linked to higher diastolic pressure.
A low-fat diet is safe for children aged 4-10 if parents follow the Food Pyramid guidelines and provide counseling or education, reducing the risk of heart disease. The study found that children on modified diets had adequate intakes of all nutrients while lowering their LDL blood levels.
A study by UC Davis researchers found that protein-deprived diet reduces life expectancy in both male and female Medflies, but females are harder hit. This reversal of the natural lifespan advantage suggests a vulnerable window of time for females during reproduction.
A recent Penn State study found that high-carbohydrate, low-fat diets may cause a drop in testosterone levels due to inadequate nutrient balance. The study revealed a positive correlation between dietary fat and resting testosterone levels before and after exercise.
Researchers found that a low-fat diet had no impact on memory loss in old mice, contrary to earlier studies suggesting a correlation between healthy eating and cognitive preservation. The study's findings add weight to theories suggesting that certain genes or stress hormones may contribute to age-related memory decline.
A diet high in fruits, vegetables, low-fat dairy products and other low-fat foods significantly lowers blood pressure, according to a multicenter study. The combination diet reduced systolic blood pressure by an average of 5.5 mm Hg and diastolic pressure by an average of 3.0 mm Hg within two weeks.
A new study by Rockefeller University and Harvard School of Public Health found that steamed shrimp is not harmful to cholesterol levels when consumed as part of a low-fat diet. In fact, the researchers suggest that it may even have beneficial effects on heart health due to its high content of n-3 fatty acids.
A study of postmenopausal women found that soy protein increased bone-mineral density, suggesting a potential role for isoflavones in maintaining bone health. The researchers also observed significant improvements in blood cholesterol profiles, with LDL cholesterol dropping by about 8% and HDL increasing by 4.5%.
A Brown University study reveals that many songbirds migrating south each autumn switch from insects to a berry-rich diet to store fat for the long haul. The study found that these 'pit stops,' crucial for tiny songbirds traveling thousands of miles, are under intense development and ecological pressure.
A very low protein diet with amino acid supplements has been shown to cure severe kidney disease in some individuals. The study suggests that this dietary therapy should be tried before drug treatment for nephrotic syndrome, which often leads to kidney failure.
Researchers at UC Davis found that diets deficient in amino acids can increase seizure severity, shorten time before seizures occur and reduce chemical stimulant needed. The study suggests specific brain regions are influenced by diet components, with implications for treating epilepsy, particularly in underdeveloped countries.
Researchers at Duke University Medical Center found no correlation between high-sugar diets and weight loss, mood alterations, or metabolic effects. Instead, they discovered that the body processes simple and complex carbohydrates similarly, regardless of sugar content.
