Black sesame has the effect of calming the nerves, honey also has the effect of calming the nerves, and walnut kernel supplements the brain. These three kinds together are very nutritious and good for your health. Besides, all three are delicious. I often buy fresh sesame seeds and walnuts at home and grind them together, and then add honey to make sesame paste. But dietotherapy is very slow, and it is impossible to have an immediate effect. But it's a good way to keep fit.
Given your gastritis, you'd better eat less. Because sesame seeds and walnut kernels are very oily foods, eating too much will definitely be harmful to the stomach.
