Butter or margarine? And if margarine, stick or tub?
Margarine is made from vegetable oils, so it contains unsaturated “good” fats – polyunsaturated and monounsaturated fats, according to Mayo Clinic. These types of fats help reduce low-density lipoprotein (LDL), or “bad,” cholesterol when substituted for saturated fat. Butter, on the other hand, is made from animal fat, so it contains more saturated fat. But not all margarines are created equal. Some margarines contain trans fat, which, like saturated fat, increases blood cholesterol levels and the risk of heart disease. In general, the more solid the margarine, the more trans fat it contains. So stick margarines usually have more trans fat than tub margarines.
Better you know
Up to 1.6 million (or about 1 in every 100) women and girls in the United States have a bleeding disorder, many undiagnosed. Bleeding disorders, such as hemophilia (and von Willebrand disease, or VWD) are conditions in which specific proteins in the blood are missing or do not work properly, making it hard for the blood to clot. The National Hemophilia Foundation in partnership with the Centers for Disease Control and Prevention have launched “Better You Know,” a campaign to raise awareness of bleeding disorders among women and girls.
Obesity outmaneuvers cancer
Obesity has been linked to increased risk for over a dozen different types of cancer, as well as worse prognosis and survival, according to Harvard Medical School. Over the years, scientists have identified obesity-related processes that drive tumor growth, such as metabolic changes and chronic inflammation, but a detailed understanding of the interplay between obesity and cancer has remained elusive. In a new study in mice, Harvard Medical School researchers have uncovered a new piece of the puzzle, with implications for cancer immunotherapy: Obesity allows cancer cells to outcompete tumor-killing immune cells in a battle for fuel. The findings, published in the journal Cell on Dec. 9, reveal that a high-fat diet reduces the numbers and antitumor activity of CD8+T cells – a critical type of immune cell – inside tumors.
Stress and heart health among women
How a woman feels about her roles at home and at work during midlife can affect several factors that influence her heart health. A study, published Dec. 11 in the Journal of the American Heart Association, found that women who felt more stressed at their jobs or in their roles as caregivers, mothers and spouses had greater odds of having high blood pressure, being overweight and not eating a healthy diet. Conversely, those who felt their roles were more rewarding were substantially more likely to be physically active and to not smoke. And that can potentially help their heart health, said lead author Andrea Leigh Stewart. Still to be answered: Do the stress and rewards influence a woman’s heart-healthy behaviors, or do those behaviors affect her feelings about her roles?
Smile (even with a mask), and your baby smiles with you
In the neonatal intensive care unit at Oregon Health & Science University’s Doernbecher Children’s Hospital, COVID-19-related restrictions meant that everybody visiting infant patients had to wear a mask, according to a report in Portland Monthly. Registered nurse Mollie Poor noticed the toll it was taking. She recalls one baby who had been born prepandemic but was still being treated when the restrictions came into place. “[The baby] had been smiling, and after a lot of prolonged mask use [by parents and the care team] she stopped smiling as much because she never saw anyone smiling back.” The NICU implemented clear masks, which have a foam rim sealing the nose and chin, but which give parents the ability to connect and smile with their babies. “[For] a lot of moms holding their babies for the first time, or breastfeeding, being able to smile down at their babies has been pretty impactful on them,” she says.
