AICR recommends choosing whole grains over refined or processed grains— in addition to being higher in nutrients and phytochemicals, whole grains contain more fiber than refined grains. Foods containing fiber protect against colorectal cancer and may keep you full longer, helping you manage your weight. Whole grains are also linked to a lower risk of heart disease and type 2 diabetes.
Scientists are not sure why whole grains and fiber are beneficial for health, but a new study in mice published in the Journal of Nutrition adds to the evidence that changes in the types of bacteria that live in the intestines—known as the gut microbiota—may be important.
The researchers fed one group of mice flour made from whole grain oats, while the other group of mice got refined flour lower in soluble fiber. Soluble fiber slows the passage of food through the digestive tract, which may help keep you feeling full longer. It is also linked to lower cholesterol and increased insulin sensitivity, important factors in the development of heart disease and type 2 diabetes.
Both diets had the same amount of protein, carbohydrate, fat, and insoluble fiber. Continue reading
A new study published this week adds to the emerging evidence linking coffee to lower risk of some cancers, giving coffee lovers another excuse to drink up.
This time, researchers found a lower risk of malignant melanoma in older adults with the highest coffee intake. Melanoma is the fifth most common cancer in the U.S. and the deadliest form of skin cancer, but exposure to ultraviolet radiation (UV) and sunburns are the only key risk factors within your control, according to the National Cancer Institute.
The new study published in the Journal of the National Cancer Institute included nearly 450,000 non-Hispanic white participants. Participants answered questions about their coffee intake and then were followed for an average of 10.5 years to see if they developed a non-invasive melanoma, known as melanoma in situ, or malignant melanoma.
Those with coffee intake of more than 4 cups per day had a 20% lower risk of malignant melanoma compared to non-coffee drinkers. High intake of regular coffee and total caffeine, but not decaffeinated coffee, were also associated with a lower risk of malignant melanoma. There was no link between coffee intake and melanoma in situ. Continue reading
Pizza is popular – for kids’ parties, family night out and even late night snacks. But pizza can pack a lot of calories and that can lead to weight gain, which can increase cancer risk.
A study published yesterday in the journal Pediatrics dissects the role pizza plays in weight and nutrition for children and adolescents. Although the researchers found that overall, daily calories from pizza are lower than a decade ago, children and adolescents who eat pizza also consume more calories, saturated fat and salt each day than non-pizza eaters.
Study authors also found that if the pizza was from a fast food restaurant or was eaten as a snack, it added even more calories than if the pizza was from school cafeterias or from home. Overall, teens averaged about 320 calories more per day when eating pizza from a fast food restaurant than days when they didn’t eat pizza at all.
Being overweight as a kid may lead to being overweight as an adult. Overweight and obese adults have an increased risk for many common cancers, type 2 diabetes and other chronic diseases.
How can you help your child learn to enjoy pizza as a meal, treat or even as a healthful contribution to their diet? Check out our blog where I give a few tips on how to order and make a healthier pizza.
