When will you eat a cup of food that is half the calories of another cup of that same food? When that food is made of larger, fluffier pieces, suggests a new study.
The study, published in the Journal of the Academy of Nutrition and Dietetics, focused on breakfast cereals. By eating flakes that were larger and took up more space in the bowl, people ate 100 calories less for breakfast than when eating the smaller, denser flaked cereal.
The findings relate to AICR’s recommendation for cancer prevention on eating mainly plant foods, which are low in calorie (energy) density. Bite for bite, many vegetables and other plant foods contain relatively few calories. That can help with weight control, which in turn reduces cancer risk. In the study, each week for four weeks, 41 breakfast eaters were offered 10 ounces (280 grams) of Wheaties.
Unbeknownst to them, the flake size was changed. One week they were served the cereal as packaged, considered the standard. The other three weeks they were given cereals where the flakes were crushed to 80%, 60% or 40% of the standard. As the flakes got smaller, the cereal took up less room in the bowl. Continue reading
For both pre- and postmenopausal breast cancers, the many studies looking on whether dietary fat matters has resulted in no clear conclusions. Now comes a study from Italy suggesting that it does for certain types of breast tumors, including the most common type.
The study suggests that consuming high amounts of total fat, and saturated fats specifically, links to increased risk of breast tumors fueled by the hormones estrogen and progesterone. About three quarters of US breast tumors are estrogen-receptor positive (ER+). The majority of those also grow in response to progesterone.
The increased risk was most pronounced for high amounts of saturated fat, the type of fat from burgers, butter and primarily animal sources.
Here’s the study abstract, published in the Journal of the National Cancer Institute.
This is one study, and it will be added to the body of evidence on breast cancer prevention in AICR/WCRF’s Continuous Update Project (CUP). In the latest CUP report, there was not enough evidence on total dietary fat to make a conclusion for pre- or postmenopausal cancers. Continue reading
If you need another reason to grab an apple today, a new study may get you inspired. The study suggests that eating just a few fruits and vegetables a day reduces the risk of dying from cancer and an earlier death. And the more produce people ate, the lower their risk of dying during the course of the study.
The study was published in the Journal of Epidemiology & Community Health.
From AICR’s report along with other research, there is already an established link between consuming high amounts of fruits and vegetables are reduced risk of certain cancers. This study both strengthens and adds to the research by focusing on mortality, from cancer, along with heart disease and any cause.
The study included approximately 65,000 participants, ages 35 or older, who represent the population of England. They had answered questions annually about how many and what types of fruit and vegetables they had eaten, as well as other health habits.
After an average of 8 years, the people who were eating seven or more fruits and vegetables each day had a 33 percent reduced risk of dying from any cause compared to their non-produce eating counterparts. Even consuming one to three fruits and vegetables a day reduced risk of death by about 10 percent, compared to those who ate none. The link was even stronger when excluding those who died during the first year of the study, which may have been due to illness. Continue reading
