About this trial
The investigators' over-arching hypothesis is that mechanical and compositional properties of chia seeds supplemented during lactation diminish obesity-induced intestinal inflammation and barrier dysfunction. The investigators hypothesize these changes will result in: 1) reduced maternal systemic inflammation (serum CRP and IL-6) and increased gut microbial diversity and richness, 2) reduced HM fat and inflammatory markers, metrics the research team have demonstrated differ in tandem with maternal metabolic health and 3) improved infant growth/body composition. To test these hypotheses, investigators will evaluate chia seed supplementation during lactation in a 6wk multi-site pilot RCT (Aim 1) and through translational studies using human enteroids (Aim 2).

Treatment groups
Trial outcomes
Primary outcomes
Breast milk
Breast milk composition primarily macronutrient composition (total fat, total carbohydrate, total protein along with caloric density). Additionally, markers of inflammation (IL-6 and CRP) along with metabolic health (glucose and insulin) will be measured in milk from the collection of a complete breast expression (\~1 to 2 ounces).
Breast Milk
Changes in breast milk will be investigated (both macro nutrients and small bioactive). Macronutrient composition will encompass total fat, protein and carbohydrate, along with caloric density. Small bioactives will include glucose, insulin, CRP and IL-6. This will be measured by collecting breast milk from a complete breast expression (\~1 to 2 ounces).
Secondary outcomes
Maternal serum levels following 6 week Chia seed intervention
Baseline and 6 weeks post intervention maternal serum (\~5 ml) will be collected. Maternal serum will be measured for lipids (cholesterol, triglycerides, HDL, LDL) along with markers of inflammation (IL-6 and CRP) and metabolic health (insulin and glucose).
