Pears + Sweet Potatoes for Infant Development
(IMiND Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores how introducing certain solid foods affects the gut health and development of infants who have been exclusively breastfed. Researchers aim to observe changes in gut bacteria, which significantly influence development, when infants begin eating pears or sweet potatoes. Mothers with healthy, single babies who are ready for solids and plan to continue breastfeeding may be suitable candidates, particularly if they reside near UC Davis in California. As an unphased trial, this study provides a unique opportunity for participants to contribute to groundbreaking research on infant nutrition and gut health.
Will I have to stop taking my current medications?
The trial protocol does not specify whether participants must stop taking their current medications. However, mothers must refrain from giving their infants certain supplements and non-study foods during the study.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Studies have shown that sweet potatoes and pears, common ingredients in baby foods, can contain heavy metals like lead and arsenic. Research indicates that sweet potatoes often have higher levels of lead, around 55 parts per billion (ppb). Pears, including pear juice, can also contain lead and arsenic. Although no safe level of heavy metals exists, experts suggest serving a variety of foods to reduce exposure.
These foods are widely available and often given to babies. Parents should be aware of these findings but understand that these foods are generally considered safe when given in moderation. Always consult a healthcare provider if there are concerns about adding new foods to a baby's diet.12345Why are researchers excited about this trial?
Researchers are excited about the potential of using pears and sweet potatoes to boost infant development because these foods are natural, nutrient-rich options. Unlike standard infant nutritional supplements, which might include synthetic ingredients or fortified vitamins, pears and sweet potatoes provide a whole-food approach packed with essential vitamins and fiber. This trial could reveal if a simple dietary addition of these fruits and vegetables can have significant benefits for infant growth and development, offering an accessible and holistic alternative to current options.
What evidence suggests that this trial's treatments could be effective for infant development?
This trial will compare the effects of sweet potatoes and pears on infant development. Research has shown that sweet potatoes, which participants in this trial may receive, provide important nutrients like vitamin A, zinc, and iron, essential for a baby's growth. They are particularly beneficial as supplementary foods in resource-limited areas. Studies have found that orange-fleshed sweet potatoes are high in beta-carotene, which the body converts into vitamin A, and young children tend to enjoy them.
Pears, another treatment option in this trial, are often used in baby foods and are known to be safe for infants. While specific nutrients are not highlighted in the sources, pears are commonly included in baby foods because they are naturally sweet and easy to digest. Both sweet potatoes and pears are popular first foods that can help introduce solid foods to infants while supporting their growth and gut health.13678Who Is on the Research Team?

Are You a Good Fit for This Trial?
This trial is for mother-infant pairs near UC Davis, California. Infants must be born full-term and exclusively breastfed for at least 5 months, ready to start solids between 4-7.5 months old without any GI abnormalities or recent antibiotic use. Mothers should be healthy, aged 21-45, non-smokers, and willing to avoid giving infants formula or supplements during the study.Inclusion Criteria

Treatment groups
Experimental Treatment
Infants will consume commercially available baby food sweet potato (SP) (Plum Organics, Just Sweet Potato) for 7 days followed by a 4 day washout period of exclusive breast milk. Participants will be instructed to offer 1-2 tablespoons of sweet potato to their infant at least three times per day for seven days in a row.
Infants will consume commercially available baby food pear (P) (Earth's Best, First Pears) for 7 days followed by a 4 day washout period of exclusive breast milk. Participants will be instructed to offer 1-2 tablespoons of pears to their infant at least three times per day for seven days in a row.
