Avocados are Good for Your Gut


Avocados are rich in nutrients, including dietary fiber and monounsaturated fat. They also improve gut health, a team of ACES scientists says. The researchers, who specialize in dietary modulation of the microbiome and its connections to health, studied how avocado consumption impacts gastrointestinal microbiota. They found people who ate avocado every day as part of a meal had a greater abundance of gut microbes that break down fiber, produced more metabolites that support gut health, and had greater microbial diversity than a control group of people who ate similarly, but avocado-free meals. In another study, they also showed an avocado a day can redistribute belly fat in women by reducing deeper, visceral abdominal fat. The researchers concluded daily avocado consumption promotes gut health by feeding the gut microbes that help us break down dietary fibers.

Bedtime Routines for Children

Getting young children to sleep at night can be a challenge for parents and caregivers. But developing consistent habits can help, according to ACES researchers. The research team studied how bedtime routines affect sleep outcomes for children during the first two years of life. They found reading books and cuddling with caregivers can make a big difference, if done consistently. Beginning these routines when infants are 3 months old promotes better sleep habits through age 2. And when caregivers engaged in more bedtime-related activities with their infants at 12 months, the children slept longer and had fewer sleep problems at ages 18 months and 24 months. The research was part of STRONG Kids 2, a program within the Family Resiliency Center promoting nutrition and healthy habits in families with young children.

Taste Loss in Cancer Survivors

Tongue with taste bud flavors outlined.

Loss of taste is a frequently underappreciated but serious side effect of disease—or disease treatment—that can diminish the desire to eat and affect the quality of life. Most survivors of squamous cell head and neck cancers report their sense of taste is changed or lost during radiation treatment and many complain of taste dysfunction long after treatment is completed. ACES researchers found the tips of the tongues of head and neck cancer survivors were significantly less sensitive to detect or identify bitter, salty, or sweet tastes than those in a control group who had never been diagnosed with cancer. This suggests certain taste bud cells or a branch of a facial nerve carrying signals from the tip of the tongue to the brain—may have been damaged during radiation therapy.

Sow Disease in Post-natal Piglets

Pregnant cow

When sows get sick during critical stages of pregnancy, the offspring are at risk of developing neurological disorders that may make them less successful in production settings. And when these piglets experience a second stressful event early in life, they're even more prone to abnormalities in the brain. That's especially true for male piglets, according to recent research from ACES animal scientists. The finding is relevant to swine producers aiming to raise the healthiest possible herds, but it also could shed light on human neurological disorders such as autism and schizophrenia. ACES scientists are global leaders in the development of the domestic pig as a biomedical research model, having mapped the pig genome, analyzed behavioral patterns, detected biomarkers of health and production, and more.
