I tried using the food command that used to work on previouse version from 1.20.6 up but now it doesn;t seem to work. 

• /give _@p nether_brick[custom_name='["",\{"text":"Chocolate","italic":false}]',lore=['["",\{"text":"It is a single bar of chocolate","italic":false}]'],food={nutrition:0.5,saturation:0.4,can_always_eat:true,eat_seconds:0.8,effects:[
  Unknown macro: {effect}

  ]}]_
