これらタンパク質などの各成分の各量が上記の数値範囲の下限を下回ると、腎機能改善用の栄養調整物の全体として、これらの各成分の不足による弊害を招く可能性がある。逆に、これらタンパク質などの成分の各量が上記の数値範囲の上限を上回ると、腎機能の低下の防止や抑制の効果を十分に実際の摂取者に与えることが困難となり、これらの各成分の過剰による弊害を招く可能性がある。
この重量比が上記の数値範囲の下限を下回ると、腎機能の低下の防止や抑制の効果を十分に実際の摂取者に与えることが困難となり、これらの各成分の不足による弊害を招く可能性がある。この重量比が上記の数値範囲の上限を上回ると、今までの食生活を大きく変えることなく、腎機能の悪化を防止や抑制することが困難となり、これらの各成分の過剰による弊害を招く可能性がある。
