【粳米】生者冷，燔者热。生不益脾，过熟则佳。苍耳同食卒心痛，马肉同食发痼疾。
【稻米】糯米也，妊娠与杂肉食之，不利其子，生寸白，久食身软缓筋故也。性寒，壅经气，
使人四肢不收，昏闷多睡，发风动气，可少食。
【秫米】似黍而小，亦可造酒，动风，不可常食。
【黍米】发宿疾，久食昏五脏好睡。小儿食，不能行，缓人筋骨，绝血脉。白黍久食，多热，
令人烦。赤黍不可合蜜，虽可作糜，不可为饭，粒着难解。五种黍米合葵食之，成痼疾于脏腑中，
食之闭气，肺病有宜此。
【生米】戏食，久为米瘕，肌疲如劳，缺米则口吐清水。
【饴糖】进食健胃，多食则动脾风。
【麦】占四时，秋种夏收。西北多霜雪，面无毒；南方少雪，有毒。小麦性壅热，小动风气，
食面后觉中毒，以酒咽汉椒三五粒，不为疾。大麦久食宜人，带生则冷，损人。麦 久食消肾，不可多。
【 麦】西川多种，山东河北人正月方种。先患冷气人不宜食。
【荞麦】性寒难消，久食动风头眩。和猪肉食八九次，患热风，脱眉须。
【粟米】食后勿食杏仁，令人吐泻。
【人米】 也，发三十六种病，八谷之中最为下，不可同川附子服。
【陈廪粟米、 米陈者】性皆冷，频食之自利。
【绿豆】治病，则皮不可去，去皮食少壅气。
【赤小豆】行小便，久食虚人，令人黑瘦枯燥，逐津液，体重。赤白豆合鱼 食之。成消渴。赤小豆
一名胡豆，合鲤鱼 食之肝黄，五年成干消。
【黑白黄褐豆、大小豆】作豉极冷，黄卷及酱皆平，多食体重。服大豆末者忌猪肉。炒豆于
一岁以上，十岁以下食之即啖猪肉，久当壅气死人。
有好食豆腐，中毒不能治，更医至中途，遇作腐人家相争，因问，妻误将莱菔汤置锅中，腐
更不成。得其说，以莱菔汤下药而愈。莱菔，萝卜也。
酱当是豆为者，令以面麦为者，食之多杀药力。夫子云∶不得其酱不食。欲五脏悦而爱之。
此亦安乐之端。
【芝麻】炒熟，乘热压出生油，但可点灯，煎炒方谓熟油可食。油发冷疾，滑骨髓，困脾脏，
经宿即气动，牙齿脾疾人不宜。陈油饮食，须逐日熬熟。黑芝麻炒食之，不生风疾。风人日食之
则步履端正，语言不謇，即胡麻也，又名巨胜子。白芝麻滑肠胃，行风气，通血脉。陈久者发霍
乱，久食抽人肌肉。麻仁多食损血脉，痿阳滑精，发女人带疾。
【粳米】生食性寒，炒熟后性热。生粳米无益于脾脏，但煮得过于熟烂则更佳。若与苍耳同食，会突然引发心痛；若与马肉同食，会诱发陈旧性疾病。
【稻米】即糯米。孕妇食用或与肉类杂食，不利于胎儿发育，会导致胎儿生出寸白虫（绦虫幼虫），这是因为其性质导致筋脉松弛的缘故。其性寒，会阻滞经络之气，使人四肢无力不收摄，头昏沉闷、嗜睡多卧，易引发风邪、扰动气机，因此应少量食用。
【秫米】形状像黍米但较小，也可以用来酿酒，食用后会动风，不宜经常食用。
【黍米】会诱发旧疾，长期食用会使五脏昏沉、嗜睡。小儿食用后，会导致行动困难，筋骨松弛，血脉凝滞。白色黍米长期食用会产生内热，令人烦躁。红色黍米不可与蜂蜜同食，虽然可以煮成粥，但不宜做成饭，因为米粒粘连难以消化。五种黍米若与葵菜同食，会在脏腑中形成顽固疾病，食用后会闭塞气机，但肺病患者适宜食用此类食物。
【生米】嬉戏时吞食生米，日久会形成“米瘕”（一种因饮食不当形成的积块），肌肉疲乏如同劳损，若停止吃米则会口吐清水。
【麦】麦子占据四季农事，秋季播种夏季收获。西北地区多霜雪，产出的面粉无毒；南方少雪，产出的面粉有毒。小麦性偏壅滞且热，轻微扰动风气，若吃面后感觉中毒，可用酒送服汉椒（花椒）三五粒，即可避免病痛。大麦长期食用对人有益，但若带生食用则性寒，损伤人体。麦类长期食用会耗损肾气，不可多吃。
【荞麦】四川西部多种植，山东、河北等地人们正月才种植。原本患有冷气病的人不宜食用。
【荞麦】性寒且难消化，长期食用会引发头风眩晕。与猪肉同食八九次，会患热风病，导致眉毛胡须脱落。
【粟米】食用后不要立即吃杏仁，否则会导致人呕吐腹泻。
【稗米】即稗子，会引发三十六种疾病，在五谷之中品质最差，不可与川附子同服。
【陈旧的廪粟米、陈旧的稗米】性质皆寒，频繁食用会导致自发性腹泻。
【绿豆】用于治疗疾病时，豆皮不可去除，若去皮食用则较少引起气机壅滞。
【赤小豆】能通利小便，长期食用会使体虚之人更加虚弱，使人变得黑瘦干枯，消耗津液，导致身体沉重。赤小豆与白豆若与鱼同食，会形成消渴病。赤小豆又名胡豆，若与鲤鱼同食，会导致肝黄，五年后发展为干消（糖尿病的一种）。
【黑白黄褐豆、大小豆】制成豆豉后极寒，豆黄及酱性平，多吃会导致身体沉重。服用大豆粉者忌食猪肉。将豆子炒制存放一年以上，若十岁以下儿童食用后又吃猪肉，久而久之会因气机壅滞致死。
有人喜欢吃豆腐，结果中毒无法救治。医生在半路途中，遇到做豆腐的人家发生争执，询问原因，得知妻子误将萝卜汤放入锅中，导致豆腐不成形。医生据此原理，用萝卜汤送服药物，患者痊愈。莱菔即萝卜。
酱应当是用豆类制作的，若用面麦制作，食用后会削弱药效。孔子说：“没有合适的酱不吃。”这是为了让五脏愉悦而喜爱它。这也是安乐的开端。
【芝麻】炒熟后，趁热压榨出油，这种油只能点灯，只有煎炸后才称为熟油，可以食用。芝麻油会引发冷疾，滑利骨髓，困顿脾脏，隔夜后会引起气机紊乱，牙齿有病或脾病的人不宜食用。陈旧的油脂用于饮食，必须每天重新熬熟。黑芝麻炒食后，不会引发风疾。风病患者每日食用，则行走端正，语言不结巴，这就是胡麻，又名巨胜子。白芝麻滑利肠胃，运行风气，通畅血脉。陈久的芝麻会引发霍乱，长期食用会抽削人的肌肉。麻仁（芝麻籽）多吃会损伤血脉，导致阳痿滑精，引发女性带下病。
[Jingmi (Coarse Rice)] Raw Jingmi is cold in nature, while roasted Jingmi is hot. Raw Jingmi does not benefit the Spleen, but overcooked Jingmi is preferable. Consuming it with Xuancao (Cocklebur) may suddenly cause heart pain; consuming it with horse meat may induce chronic diseases.
[Daomi (Rice), also known as Nuomi (Glutinous Rice)] For pregnant women, consuming this with mixed meats is detrimental to the fetus and may cause the fetus to develop Taenia solium larvae (Cestoda), due to its property of causing flaccidity of the sinews. Its nature is cold and it obstructs the flow of Qi in the meridians, leading to weakness and lack of control in the four limbs, dizziness, mental confusion, excessive sleepiness, wind generation, and Qi disturbance. Therefore, it should be consumed in small amounts.
[Shumi (Millet for Wine Making)] It resembles Shumi (Broomcorn Millet) but is smaller, and can also be used to brew wine. It generates wind and should not be eaten frequently.
[Shumi (Broomcorn Millet)] It may trigger latent diseases. Long-term consumption causes the five Zang organs to become dull and induces sleepiness. In children, it leads to inability to walk, relaxation of sinews and bones, and obstruction of blood vessels. White Shumi, if consumed long-term, generates excessive heat and causes irritability. Red Shumi should not be combined with honey. Although it can be made into porridge, it is unsuitable for making rice because the grains stick together and are difficult to digest. If the five types of Shumi are eaten with Kai (Malva verticillata), it forms chronic diseases within the Zang-Fu organs, blocks Qi, but is suitable for patients with Lung disease.
[Raw Rice] Playing with and swallowing raw rice can lead to "Mi Jia" (rice mass/accumulation) over time, muscle fatigue resembling exhaustion, and salivation of clear fluid when rice intake stops.
[Yitang (Malt Sugar)] Consumed in moderation, it strengthens the Stomach; however, excessive consumption triggers Spleen Wind.
[Wheat/Mai] Wheat cultivation spans the seasons, sown in autumn and harvested in summer. In the northwest, where there is much frost and snow, the flour is non-toxic; in the south, with less snow, the flour is considered toxic. Xiaomai (Common Wheat) has a cloying and hot nature, slightly stirring wind Qi. If one feels poisoned after eating noodles, swallowing 3-5 grains of Hanjiao (Zanthoxylum bungeanum) with wine will prevent illness. Damai (Barley) is beneficial for long-term consumption, but raw barley is cold and damaging to the body. Long-term consumption of Mai depletes Kidney essence, so it should not be eaten in excess.
[Qiaomai (Buckwheat)] Widely planted in Western Sichuan, while people in Shandong and Hebei plant it only in the first lunar month. Those who already suffer from Cold Qi should avoid eating it.
[Qiaomai (Buckwheat)] Its nature is cold and difficult to digest. Long-term consumption triggers Head Wind and dizziness. Eating it with pork eight or nine times can cause Hot Wind disease, leading to the loss of eyebrows and beard.
[Suli (Foxtail Millet)] Do not eat Apricot Kernels immediately after consumption, as this causes vomiting and diarrhea.
[Baimi (Barnyard Grass Seed)] Also known as Baizi, it triggers thirty-six types of diseases and is the lowest quality among the Eight Grains. It should not be taken with Chuan Fuzi (Prepared Aconite Lateral Root).
[Chen Lin Suli (Aged Foxtail Millet) and Chen Baimi (Aged Barnyard Grass Seed)] Both have a cold nature. Frequent consumption leads to spontaneous diarrhea.
[Lvdou (Mung Bean)] When used for treating diseases, the skin should not be removed. Removing the skin reduces the risk of Qi stagnation.
[Chixiaodou (Red Adzuki Bean)] Promotes urination. Long-term consumption weakens deficient individuals, causing them to become dark, thin, and dry, depleting body fluids and causing heaviness. Combining Chixiaodou and Bai Dou (White Beans) with fish leads to Xiao Ke (Wasting-Thirst syndrome). Chixiaodou is also called Hudou. Combining it with Carp leads to Liver Yellow Jaundice, which develops into Gan Xiao (Dry Wasting-Thirst) after five years.
[Heibai Huanghe Dou (Black, White, Yellow, Brown Beans) and Da Xiao Dou (Large and Small Beans)] Made into Dou Chi (Fermented Soybeans), they are extremely cold. Huang Juan (Soybean Sprouts) and Jiang (Soy Sauce/Paste) are neutral. Excessive consumption causes body heaviness. Those taking Douda Mo (Soybean Powder) must avoid pork. If beans are stir-fried and stored for more than a year, and a child under ten eats them followed by pork, it may eventually cause death due to Qi stagnation.
There was a case of someone who loved eating Tofu and suffered from poisoning that could not be cured. The physician, on his way to treat the patient, encountered a dispute at a tofu-making household. Upon inquiry, he learned that the wife had mistakenly put Laifu Tang (Radish Decoction) into the pot, ruining the Tofu. Understanding this principle, the physician administered medicine with Radish Decoction, and the patient recovered. Laifu refers to Luobo (Radish).
Jiang (Paste/Sauce) should be made from beans. If made from wheat/flour, it consumes medicinal efficacy. Confucius said, "If the sauce is not proper, I do not eat." This is to make the Five Zang organs happy and affectionate. This is also the beginning of peace and joy.
[Zhima (Sesame)] Stir-fried and pressed while hot yields raw oil, which is only suitable for lamps. Only oil obtained by frying/cooking is considered "cooked oil" and edible. Sesame oil triggers cold diseases, lubricates bone marrow, and burdens the Spleen. After overnight storage, it disturbs Qi movement. It is unsuitable for those with dental or Spleen diseases. Old sesame oil used for cooking must be re-boiled daily. Black Sesame, when stir-fried and eaten, does not generate wind diseases. Patients with Wind disorders who eat it daily walk steadily and speak clearly without slurring. This is also known as Huma (Sesame) or Jushengzi. White Sesame lubricates the intestines and stomach, moves Wind Qi, and unblocks blood vessels. Old sesame can trigger Huoluan (Cholera-like vomiting and diarrhea); long-term consumption wastes muscle tissue. Mahren (Sesame Seeds) in excess damages blood vessels, causes Yang deficiency with seminal emission, and triggers Dai Xia Bing (Leukorrhea) in women.
