• The 1941 National Nutrition Conference on Defence announced the first recommended dietary allowances (RDAs), which provided guidelines for total calories and specific nutrients including protein, calcium, phosphorus, iron, and vitamins.
• The EAT-Lancet Index (ELI), which uses semi-quantitative scores, shows positive associations with polyunsaturated fatty acids and vitamins D and E, but negative associations with protein, B-complex vitamins, phosphorus, calcium, and iron.
• The procedure for mineral digestion involves digesting leaf samples in a 20 mL diacid mixture of HCl and HClO4 in a 4:1 volumetric ratio, bringing the final volume to 100 mL, and using the resulting extract to analyze Phosphorus (P), Potassium (K), Calcium (Ca), and Sulfur (S).
• Ions of calcium, phosphorus, sodium, potassium, and magnesium play vital roles in the metabolic processes of the human body.
• Hemp grains, which are edible seeds harvested for human or animal consumption, contain approximately 5.6% minerals (calcium, magnesium, potassium, and phosphorus), 25% protein, 28% total dietary fiber, and more than 30% oil.
• The fruit pulp of Ziziphus lotus contains significantly higher levels of sugar (35.25 to 48.87%), phosphorus (63.114 to 155.269 mg 100−1g), sodium (34.8 to 56.91 ppm), calcium (91.78 to 382.69 ppm), β-carotene (36.4 to 46 μg g−1), lycopene (59.15 to 100.25 μg g−1), and chlorophyll a (3.6 to 7.2 μg g−1) compared to the seeds.
• Calcium and phosphorus form calcium-phosphate crystals, which make up a large part of human bones.
• Mineral analysis of Bellevalia forniculata, Beta corolliflora, Caltha polypetala, and Primula auriculata showed high amounts of potassium (892.93–2,663.63 mg/100 g), phosphorus (239.57–636.77 mg/100 g), calcium (279.90–341.33 mg/100 g), magnesium (103.43–363.27 mg/100 g), iron (11.06–37.13 mg/100 g), manganese (1.56–5.39 mg/100 g), and zinc (2.28–3.36 mg/100 g).
• The HSDI and ELDS indices, which are based on binary scoring, correlated inversely with several nutrients including protein, DHA, EPA+DHA, riboflavin, niacin, pantothenic acid, vitamin B-6, vitamin B-12, vitamin D, iodine, phosphorus, zinc, calcium, and iron.
• Phosphorus in a plant digest is analyzed using the Canada-molybdate yellow color method, Potassium and Calcium are analyzed using a flame photometer, Sulfur is evaluated using a turbidimetric process, and Sodium, Zinc, Copper, Iron, and Manganese are determined using atomic absorption spectrophotometry.
• Basil plants grown under a red-to-blue light ratio of 3:1 show accumulation of nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), and iron (Fe).
• The human body contains inorganic minerals, including calcium, phosphorus, sodium, magnesium, and iron.
• Common minerals analyzed in medicinal plants include calcium, phosphorus, potassium, sulfur, and nitrogen, which contribute to bone health, immune function, enzyme activation, and antioxidant defense mechanisms.
• Mustard plants grown under a blue-to-red light ratio of 1:1 show accumulation of phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), sulfur (S), manganese (Mn), iron (Fe), zinc (Zn), copper (Cu), and boron (B).
• Dill plants grown under red light show accumulation of phosphorus (P), potassium (K), calcium (Ca), and zinc (Zn).
