Meat can be an important source of much-needed protein in an infant’s diet during the transition to solid foods, according to the study, published in the American Journal of Clinical Nutrition.
The researchers found the pureed meats promoted a greater rate of growth — with length of nearly one inch greater compared to the dairy-fed group at 12 months of age, with no increase in risk of being overweight at the completion of the seven-month study.
“Meat, such as pork, provides important micronutrients, is an excellent source of protein and can be an important complementary food for infants who are ready for solid foods,” said lead study author Minghua Tang, Assistant Professor of Pediatrics at University of Colorado Denver-Anschutz, in the US.
In the study, a small group of healthy, formula-fed infants ate meat-based complementary foods, such as pureed ham and beef, or dairy-based complementary foods from ages five to 12 months old, increasing their protein intake from two grams of protein per kg each day before the study up to three grams per kg each day during the study period.
“Our research suggests introducing higher amounts of protein and introducing meat, such as pork, into the diet at five months could be potentially beneficial for linear growth (length gain),” Tang said.
While the protein increased, both calories and fat intakes stayed the same between the meat and dairy groups, regardless of protein source.

Excess use of social media may lead to depression and loneliness
Excessive use of social media like Facebook, Snapchat or Instagram could lead to depression and loneliness as this habit is associated with poor well-being,researchers have warned.
A new study, being published in the Journal of Social and Clinical Psychology by researchers at the University of Pennsylvania, showed that limiting screen time on these apps could boost one’s wellness.
The study has tried to look into the causal side of things, and see whether people may actually feel better when they cut down on social media.
“Our findings strongly suggest that limiting social media use to approximately 30 minutes per day may lead to significant improvement in well-being,” the authors concluded.
“When you are not busy getting sucked into clickbait social media, you are actually spending more time on things that are more likely to make you feel better about your life,” said Melissa Hunt, associate director of clinical training at the University of Pennsylvania in the US.
For the study, researchers from the varsity, included 143 undergraduate participants. The team designed their experiment to include the three platforms most popular with the participants.
They monitored the students for a week to get a baseline reading of their social media use, and gave them questionnaires that assessed their well-being according to seven different factors: social support, fear of missing out (aka FOMO), loneliness, autonomy and self-acceptance (a measure of psychological well-being), anxiety, depression, and self-esteem.
They collected objective usage data automatically tracked by iPhones for active apps, not those running in the background, and asked respondents to complete a survey to determine mood and well-being.
“Using less social media than you normally would leads to significant decreases in both depression and loneliness. These effects are particularly pronounced for folks who were more depressed when they came into the study,” Hunt told Science Daily.
The researchers chose to limit social media, rather than have subjects stop using it altogether, because it was a more realistic option, she noted.
