According to research reviewed by Gram, babies who ate poultry during their first year had higher diet quality scores by age one. In a 2026 study of 135 infant and caregiver groups in Austin, Texas, poultry eaters scored 0.14 higher on a 0-to-1 diet quality index than non-eaters at 12 months.
According to research reviewed by Gram, babies who ate poultry, eggs, or beef during their first year tended to have healthier diets by age one. The study followed 135 mother, infant, and caregiver groups in Austin, Texas, starting when babies were 5 months old and tracking what they ate until 12 months. Poultry eaters scored higher on a diet quality measure that runs from 0 to 1. Pork was linked to slightly greater length gains, but this finding was less certain. A coaching program that encouraged responsive feeding did not change how often babies ate animal foods. The results suggest that adding these protein sources during complementary feeding may help build a nutritious diet, though the study cannot prove cause and effect.
Key Statistics
A 2026 study of 135 mother, infant, and caregiver groups in Austin, Texas, found that 77% of babies had eaten poultry in the past week by 12 months of age.
A 2026 study published in The Journal of Nutrition found that babies who ate poultry had diet quality scores 0.14 higher on a 0-to-1 scale at 12 months than babies who did not eat poultry.
A 2026 study of 135 infants in Austin, Texas, found that pork consumption by 12 months was associated with length-for-age scores about 0.48 higher on a standardized growth scale.
The Quick Take
- What they studied: Researchers wanted to know how often babies eat animal foods like meat, poultry, fish, and eggs during the months when they start solid foods, and whether those foods are linked to better diet quality and growth at age one.
- Who participated: 135 groups of a mother, an infant, and a caregiver, all living in Austin, Texas. Babies joined at age 5 months, and their eating habits were tracked until they turned 12 months old.
- Key finding: At 12 months, 77% of babies had eaten poultry in the past week and 72% had eaten eggs. Babies who ate poultry scored 0.14 higher on a 0-to-1 diet quality scale than babies who did not, a difference that was statistically reliable.
- What it means for you: If you are introducing solid foods, adding poultry, eggs, or beef may help your baby’s overall diet quality. These findings come from one small study in one city, so talk with your pediatrician before making big changes to your baby’s diet, especially if your baby has allergies or other health needs.
The Research Details
This study used data from the MAGIC randomized trial, a larger project testing ways to help parents feed babies. Families were split into groups. One group received coaching on responsive feeding, which means following a baby’s hunger and fullness cues. A second group received general safety information as a comparison. A third group received coaching plus free food.
Researchers asked caregivers about the foods babies ate using two tools: a 7-day food frequency questionnaire, which lists how often specific foods were eaten, and a 24-hour recall, where caregivers describe everything the baby ate the day before. Between 5 and 12 months, these records were used to calculate an infant dietary quality index, a score from 0 to 1 that reflects how varied and balanced a baby’s diet was.
At 12 months, researchers measured each baby’s weight and length. They then used statistical models that adjusted for other factors, such as family background, to see whether eating specific animal foods was linked to diet quality and growth.
Following the same babies over a full year lets researchers see patterns that a single snapshot cannot show. Because the data were collected repeatedly, the team could track how eating habits changed as babies grew and compare babies who ate certain foods with those who did not over time.
The trial design also helped. Since the study already had families enrolled and coached, researchers could look at which foods babies actually ate, even though the coaching itself did not change how often animal foods were eaten.
Strengths include a randomized trial design, repeated diet tracking over seven months, and a registered study protocol (NCT04177472). Measurements at 12 months used standard growth charts. However, most diet information came from caregivers’ memories or self-reports, which can contain errors. The study also included a relatively small group of 135 families from a single city, so results may not apply to every community. Because this analysis looked at which foods babies chose to eat rather than randomly assigning foods, the findings show associations rather than proof that the foods caused the differences.
What the Results Show
Animal foods became more common in babies’ diets as they grew from 6 to 12 months. By their first birthday, most babies had eaten poultry (77%), eggs (72%), and beef (68%) in the previous week. Fewer had eaten fish (30%) or pork (25%) during that same period.
After adjusting for other factors, babies who ate poultry, eggs, or beef across their first year had higher diet quality scores than babies who did not eat them. Poultry showed the strongest link, with a score increase of 0.12 across infancy (95% confidence range 0.04 to 0.19). Eggs (0.06) and beef (0.07) showed smaller increases.
At 12 months specifically, poultry eaters again had higher diet quality scores (0.14, 95% confidence range 0.05 to 0.23). The coaching program itself did not change diet quality scores or how often babies ate animal foods, which suggests that coaching alone was not enough to shift these eating habits.
Babies who ate pork by 12 months had longer length-for-age scores, averaging about 0.48 higher on a standardized growth scale (95% confidence range 0.03 to 0.92). This suggests a possible link between pork and linear growth, but the range is wide and the finding should be considered preliminary. The free-food arm of the trial also did not produce a clear change in animal food intake.
Public health guidance has long encouraged iron-rich and protein-rich foods during the start of solids, and these findings fit that advice. Meat and eggs provide iron, zinc, and other nutrients that babies need as their own stores decline around six months. This study adds detailed, year-long tracking of how often specific animal foods were actually eaten, which is less common in published research.
The study included only 135 families from Austin, Texas, so the results may not reflect babies in other regions, cultures, or income levels. Diet data relied on caregiver reports, which may be incomplete or inaccurate. The researchers looked at which foods babies ate rather than assigning foods at random, so family habits or other unmeasured factors may explain some of the differences. The pork and growth finding had a wide range of possible values, so it could be a chance result. Finally, the study measured diet quality at 12 months only, so it cannot show whether these eating patterns affect health later in childhood.
The Bottom Line
Moderate confidence: Offering poultry, eggs, and beef as babies start solid foods appears to support a higher-quality diet by 12 months. Poultry showed the clearest link. Lower confidence: Pork may support length growth, but this needs confirmation in larger studies. Caregivers should follow current pediatric guidance on introducing foods, including attention to allergens and food safety.
Parents and caregivers introducing solid foods to babies around 6 months old, along with pediatricians, dietitians, and childcare providers, may find these results useful. Families who follow vegetarian or vegan diets for religious, ethical, or health reasons should discuss plant-based options with a health professional. Babies with food allergies or medical conditions should only follow new feeding plans under medical supervision.
Improvements in a baby’s diet quality can appear within weeks of adding these foods to regular meals, since the diet score reflects what a baby eats over time. Changes in growth take longer to assess and depend on many factors, including genetics, overall nutrition, and health. Expect steady progress over several months rather than rapid results, and check in with your pediatrician at regular well-child visits.
Frequently Asked Questions
Does eating chicken help babies get a better diet in their first year?
Babies who ate poultry during their first year had higher diet quality scores at 12 months, according to a 2026 study of 135 families in Austin, Texas. The difference was about 0.14 on a 0-to-1 scale. The study shows an association, not proof that chicken alone caused the improvement.
When should I start giving my baby meat and eggs?
Families in the study began tracking animal food intake at 5 months and saw intake rise steadily through 12 months. Most babies had eaten poultry, eggs, and beef by their first birthday. Talk with your pediatrician about timing, allergen introduction, and any feeding concerns before starting.
Does pork help babies grow taller in the first year?
A 2026 study found that babies who ate pork by 12 months had length-for-age scores about 0.48 higher, with a wide confidence range of 0.03 to 0.92. Because the finding is preliminary and based on a small sample, researchers recommend more studies before drawing firm conclusions.
Can feeding coaching increase how much meat babies eat?
In this 2026 trial of 135 families, a responsive feeding coaching program did not change how often babies ate animal foods or their diet quality scores. Researchers suggest that coaching alone may not be enough to shift eating habits, and families may need additional support.
Want to Apply This Research?
- Log each animal food your baby eats (poultry, eggs, beef, fish, pork) once per day, along with the approximate serving size, and count how many days per week each food appears. Aim to see at least three to four days per week of protein-rich animal foods during the second half of the first year.
- Add one new animal food to a meal each week, such as shredded chicken, mashed egg, or soft-cooked ground beef, and note how your baby responds. Use the app’s reminder feature to prompt you when a food category has not been logged for several days.
- Review the food log monthly to spot trends across the first year, and bring the summary to well-child visits. Track which foods your baby accepts and any reactions or allergies, and update your feeding plan with your pediatrician as your baby reaches new milestones.
