We evaluate the light, strange and charm scalar content of the nucleon usingone lattice QCD ensemble generated with two degenerate light quarks with massfixed to their physical value. We use improved techniques to evaluate thedisconnected quark loops to sufficient accuracy to determine the strange andcharm nucleon $\sigma$-terms. in addition to the light quark content$\sigma_{\pi N}$. We find $\sigma_{\pi N}$=$37.2(2.6)(^{4.7}_{2.9})$ MeV$\sigma_{s}$=$41.1(8.2)(^{7.8}_{5.8})$ MeV and$\sigma_c$=$79(21)(^{12}_{\phantom{1}8})$ MeV, where the first error isstatistical and the second is the systematic error due to the determination ofthe lattice spacing, the assessment of finite volume and residual excited stateeffects.
