Most tremors in both hands may lead to Parkinson’s disease. Parkinson’s syndrome, a degenerative disease of the substantia nigra and nigrostriatal pathways that occurs in adults over middle age. The APDA describes people who begin the disease at an age younger than 40 as young adults with Parkinson’s disease. The etiology of primary tremor paralysis is not yet known, about 10% of patients have a family history; some patients can be due to encephalitis, cerebral arteriosclerosis, traumatic brain injury, hypoparathyroidism, carbon monoxide, manganese, mercury, cyanide, reserpine, phenothiazine poisoning and antidepressant (methylamine oxidase inhibitor, etc.) can cause Parkinson’s disease similar to the performance of Parkinson’s syndrome. Prevention and alleviation of double-handed tremor leading to Parkinson’s disease should pay attention to a reasonable diet: 1, Parkinson’s disease is mostly seen in the elderly, while combined with vegetative nerve dysfunction, digestive function is more than reduced gastrointestinal peristalsis weakness, spasms, prone to constipation and excessive oil secretion of the skin and so on. Should be combined with the patient’s condition, dietary preferences, pay attention to the ratio of food structure, side dishes, meat and vegetables, as well as color varieties of collocation. Eat more foods rich in fiber and easy to digest, eat more fresh vegetables, fruits, drink more water, eat more tyrosine-containing foods such as melon seeds, almonds, sesame seeds, skim milk, etc. can promote the synthesis of dopamine in the brain, and properly control the intake of fat. 2, protein diet should not be excessive, blindly give too high protein diet can reduce the efficacy of levodopa, because the protein digestion of a large number of neutral amino acids, can compete with levodopa into the brain and affect its efficacy. Therefore, the supply of protein can be ensured by giving eggs, milk, fish and meat in the diet, and the daily requirement is 0.8-1.2g/kg body weight. The daily requirement is 0.8-1.2g/kg body weight. If there is fever, bedsores and other conditions, the supply of protein should be increased. 3, for chewing, swallowing dysfunction, eating in a sitting position is appropriate, should choose easy to chew, easy to swallow, high nutrition, high fiber food. Recall the swallowing steps before eating. Let them swallow the excess saliva in the mouth when eating, move the food around with the tongue when chewing, eat less at a time and eat slowly, drink water after eating and swallow the residual food to prevent aspiration pneumonia. 4, for patients with diabetes mellitus, should be given diabetic diet; with coronary heart disease and hypertension patients, high sugar, high vitamin, moderate protein diet is appropriate, limit the intake of animal fat and salt. Nutrition plays a very important role in the health status of Parkinson’s disease patients. Diet therapy is one of the adjunctive treatments for Parkinson’s disease, aiming to maintain better nutrition and physical condition of the patient, and by adjusting the diet, the medication can achieve better results. The diet of Parkinson’s disease patients has many of the same basic principles as that of the general population, but it also needs to be adjusted appropriately according to their own conditions.
