“…Previous studies documented this observation among adults 18,19,34,35 and in a small homogeneous sample of young children and adolescents. 34 This is also the first study to show inverse associations between PMI and measures of bone status among early adolescent girls of Asian, Hispanic, and non-Hispanic white backgrounds.…”

“…9,16,17 Research in adults showed that individuals who perceive themselves to be milk intolerant are more likely to avoid milk and not to make any effort to consume enough calcium. 18,19 However, those studies did not include measures of bone mass. Studies of milk avoidance behaviors in children reported overall reduced bone mass and increased incidence of bone fractures.…”

“…In Australia, dairy avoidance may be practiced by 17% of the population, of whom the majority (13%) avoid dairy on the basis of self-reported negative reactions to dairy products ( 1 ). This trend is evident globally ( 2 , 3 ), where perceived or actual intolerance to cow milk (CM)—either due to lactose or other components of milk ( 4 )—influences consumption behaviors ( 5 , 6 ). Dairy products are recognized as an important source of nutrients ( 7 , 8 ), including calcium and high quality protein ( 7 ), essential for growth and development.…”

Circulating Branched Chain Amino Acid Concentrations Are Higher in Dairy-Avoiding Females Following an Equal Volume of Sheep Milk Relative to Cow Milk: A Randomized Controlled Trial

et al. 2020

Background: Intolerances to bovine dairy are a motivating factor in consumers seeking alternate-or replacement-dairy beverages and foods. Sheep milk (SM) is an alternate dairy source, with greater protein, although similar amino acid composition compared to cow milk (CM). Studies are yet to address the appearance of circulating amino acids following consumption of SM, relative to CM, in humans. Objective: To clinically determine the appearance of branched chain amino acids, and other amino acids, in circulation in response to equal servings of SM and CM, in females who avoid dairy products. Design: In a double-blinded, randomized, cross-over trial, 30 self-described dairy avoiding females (20-40 years) drank 650 mL of SM or CM that were reconstituted from the spray dried powders (30 and 25 g in 180 mL water, respectively) on separate occasions, following an overnight fast. After reconstitution, the energy and protein provided by SM was higher than for CM (2,140 vs. 1,649 kJ; 29.9 vs. 19.4 g protein); content of branched chain amino acids (BCAAs) were 10.5 and 6.5 mg•mL −1 , respectively. Blood samples were collected at fasting and at regular intervals over 5 h after milk consumption. Plasma amino acids were measured by HPLC. Results: 80% of subjects self-identified as lactose intolerant, and the majority (47%) "avoided drinking milk" "most of the time". SM resulted in greater plasma appearance of BCAAs at 60 min (641.1 ± 16.3 vs. 563.5 ± 14.4 µmol•L −1 ; p < 0.001) compared with CM. SM similarly resulted in elevated postprandial concentrations of the amino acids lysine, methionine, and proline, particularly at 240 min (time × milk interactions p = 0.011, 0.017, and p = 0.002, respectively). Postprandial increases in plasma alanine concentrations were sustained to 120 min after CM (time × milk interaction p = 0.001) but not after SM, despite greater quantities provided by SM. Milan et al. Sheep Milk Aminoacidaemia in Dairy-Avoiders Conclusions: SM is a rich source of protein, and relative to CM, provides a greater quantity of BCAAs, with a corresponding elevation of the postprandial circulating BCAA response. SM is therefore a possible dairy alternative of benefit to those who need to increase total protein intake or for individuals with heightened protein requirements.

“…The NIH estimate of 30-50 million milk avoiders is supported by a survey by Elbon et al [28] demonstrating that 17% of Whites and 35% of Blacks indicated a perceived milk intolerance. The National Dairy Council African American Lactose Intolerance Study [28] reported that 24% of respondents considered themselves lactose intolerant, and 49% reported some physical discomfort at some time following dairy food consumption, of which 27% said they experience discomfort all the time. Evidence suggests that all maldigesters have a similar potential for intolerance [29,30].…”

“…35% of African-American maldigesters are estimated to be intolerant since only 75% of African-Americans are maldigesters) to the general US population, at least 25 million (1/3 of 75 million) Americans are avoiding dairy foods due to lactose intolerance. If the 17% figure from Elbon et al [28] is used, 50 million Americans are avoiding dairy foods.…”

Lactose Intolerance: An Unnecessary Risk for Low Bone Density

The potential for lactose intolerance causes 25-50 million Americans and an unknown number of people around the world to avoid milk. Milk avoidance is a significant risk factor for low bone density. Individuals who avoid milk, due to intolerance or learned aversion, consume significantly less calcium and have poorer bone health and probable higher risk of osteoporosis. Lactose intolerance is easily managed by: (1) regular consumption of milk that adapts the colon bacteria and facilitates digestion of lactose; (2) consumption of yogurts and cheeses and other dairy foods low in lactose;(3) consumption of dairy foods with meals to slow transit and maximize digestion, and (4) use of lactose-digestive aids. As dairying spreads around the world to new markets and dairy foods become the dominant source of calcium in these markets, the potential for lactose intolerance will grow. Management of lactose intolerance globally will require both education and product development.The potential for lactose intolerance causes 25-50 million Americans and an unknown number of people around the world to avoid milk. Milk avoidance is a significant risk factor for low bone density. Individuals who avoid milk, due to intolerance or learned aversion, consume significantly less calcium and have poorer bone health and probable higher risk of osteoporosis. Milk is also an excellent source of high quality protein and other nutrients, such as potassium, sodium, and B vitamins, plus water. Research over the past 30 years demonstrates that lactose intolerance is easily managed by: (1) regular consumption of milk that adapts the colon bacteria and facilitates digestion of lactose; (2) consumption of yogurts and cheeses and other dairy foods low in lactose; (3) consumption of dairy foods with meals to slow transit and maximize digestion, and (4) use of lactose digestive aids.
