Examples include the need to conduct research on 1) the dietary needs and intakes of older adults, whether polypharmacy plays a role in nutritional adequacy, and whether comorbidities, such as poor dentition, musculoskeletal difficulties, arthralgias, vision loss, and other age-related symptoms, affect their ability to establish and maintain proper nutritional status; 2) nutrition transitions from early childhood to adolescence to identify how and why diets change so rapidly during this period, the driving forces behind these changes, and effective programs to maintain positive nutrition habits established in young children; 3) the validity, reliability, and reproducibility of new biomarkers of nutritional status; 4) the effects of fortification strategies and supplement use on consumer behaviors and diets related to calcium, vitamin D, potassium, iron, and fiber; and 5) design approaches to quantify diets in large population-based studies.","tracks":[{"project":"LitCovid-PD-FMA-UBERON","denotations":[{"id":"T68686","span":{"begin":289,"end":298},"obj":"Body_part"}],"attributes":[{"id":"A69909","pred":"fma_id","subj":"T68686","obj":"http://purl.org/sig/ont/fma/fma75150"},{"subj":"T68686","pred":"source","obj":"LitCovid-PD-FMA-UBERON"}]},{"project":"LitCovid-PD-UBERON","denotations":[{"id":"T8","span":{"begin":289,"end":298},"obj":"Body_part"}],"attributes":[{"id":"A8","pred":"uberon_id","subj":"T8","obj":"http://purl.obolibrary.org/obo/UBERON_0003672"},{"subj":"T8","pred":"source","obj":"LitCovid-PD-UBERON"}]},{"project":"LitCovid-PD-MONDO","denotations":[{"id":"T69","span":{"begin":343,"end":354},"obj":"Disease"}],"attributes":[{"id":"A69","pred":"mondo_id","subj":"T69","obj":"http://purl.obolibrary.org/obo/MONDO_0001941"},{"subj":"T69","pred":"source","obj":"LitCovid-PD-MONDO"}]},{"project":"LitCovid-PD-CLO","denotations":[{"id":"T19397","span":{"begin":217,"end":218},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"}],"attributes":[{"subj":"T19397","pred":"source","obj":"LitCovid-PD-CLO"}]},{"project":"LitCovid-PD-CHEBI","denotations":[{"id":"T36","span":{"begin":920,"end":927},"obj":"Chemical"},{"id":"T38","span":{"begin":929,"end":938},"obj":"Chemical"},{"id":"T39","span":{"begin":929,"end":936},"obj":"Chemical"},{"id":"T40","span":{"begin":940,"end":949},"obj":"Chemical"},{"id":"T41","span":{"begin":951,"end":955},"obj":"Chemical"}],"attributes":[{"id":"A36","pred":"chebi_id","subj":"T36","obj":"http://purl.obolibrary.org/obo/CHEBI_22984"},{"id":"A37","pred":"chebi_id","subj":"T36","obj":"http://purl.obolibrary.org/obo/CHEBI_29320"},{"id":"A38","pred":"chebi_id","subj":"T38","obj":"http://purl.obolibrary.org/obo/CHEBI_27300"},{"id":"A39","pred":"chebi_id","subj":"T39","obj":"http://purl.obolibrary.org/obo/CHEBI_33229"},{"id":"A40","pred":"chebi_id","subj":"T40","obj":"http://purl.obolibrary.org/obo/CHEBI_26216"},{"id":"A41","pred":"chebi_id","subj":"T41","obj":"http://purl.obolibrary.org/obo/CHEBI_18248"},{"subj":"T36","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T38","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T39","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T40","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T41","pred":"source","obj":"LitCovid-PD-CHEBI"}]},{"project":"LitCovid-PD-GO-BP","denotations":[{"id":"T10","span":{"begin":343,"end":349},"obj":"http://purl.obolibrary.org/obo/GO_0007601"},{"id":"T11","span":{"begin":889,"end":898},"obj":"http://purl.obolibrary.org/obo/GO_0007610"}],"attributes":[{"subj":"T10","pred":"source","obj":"LitCovid-PD-GO-BP"},{"subj":"T11","pred":"source","obj":"LitCovid-PD-GO-BP"}]},{"project":"LitCovid-PubTator","denotations":[{"id":"198","span":{"begin":714,"end":722},"obj":"Species"},{"id":"199","span":{"begin":300,"end":328},"obj":"Disease"},{"id":"200","span":{"begin":330,"end":341},"obj":"Disease"},{"id":"201","span":{"begin":343,"end":354},"obj":"Disease"}],"attributes":[{"id":"A198","pred":"tao:has_database_id","subj":"198","obj":"Tax:9606"},{"id":"A199","pred":"tao:has_database_id","subj":"199","obj":"MESH:D009140"},{"id":"A200","pred":"tao:has_database_id","subj":"200","obj":"MESH:D018771"},{"id":"A201","pred":"tao:has_database_id","subj":"201","obj":"MESH:D014786"},{"subj":"198","pred":"source","obj":"LitCovid-PubTator"},{"subj":"199","pred":"source","obj":"LitCovid-PubTator"},{"subj":"200","pred":"source","obj":"LitCovid-PubTator"},{"subj":"201","pred":"source","obj":"LitCovid-PubTator"}],"namespaces":[{"prefix":"Tax","uri":"https://www.ncbi.nlm.nih.gov/taxonomy/"},{"prefix":"MESH","uri":"https://id.nlm.nih.gov/mesh/"},{"prefix":"Gene","uri":"https://www.ncbi.nlm.nih.gov/gene/"},{"prefix":"CVCL","uri":"https://web.expasy.org/cellosaurus/CVCL_"}]},{"project":"LitCovid-sentences","denotations":[{"id":"T186","span":{"begin":0,"end":90},"obj":"Sentence"},{"id":"T187","span":{"begin":91,"end":1045},"obj":"Sentence"}],"namespaces":[{"prefix":"_base","uri":"http://pubannotation.org/ontology/tao.owl#"}],"attributes":[{"subj":"T186","pred":"source","obj":"LitCovid-sentences"},{"subj":"T187","pred":"source","obj":"LitCovid-sentences"}]},{"project":"LitCovid-PD-HP","denotations":[{"id":"T41","span":{"begin":330,"end":341},"obj":"Phenotype"},{"id":"T42","span":{"begin":343,"end":354},"obj":"Phenotype"}],"attributes":[{"id":"A41","pred":"hp_id","subj":"T41","obj":"http://purl.obolibrary.org/obo/HP_0002829"},{"id":"A42","pred":"hp_id","subj":"T42","obj":"http://purl.obolibrary.org/obo/HP_0000572"},{"subj":"T41","pred":"source","obj":"LitCovid-PD-HP"},{"subj":"T42","pred":"source","obj":"LitCovid-PD-HP"}]}],"config":{"attribute
