Signaling molecules, chemical messengers, usually peptides or steroids, produced by one tissue and conveyed by the bloodstream to another to influence physiological activity, such as development, growth or metabolism. Hormones can also affect heart rate, blood flow, alterations in mental state, digestive and reproductive processes in the body. ​
Examples of human hormones:

• Adrenalin triggering "fight or flight" responses in the nervous system
• Androgens (including testosterone) responsible for male secondary sex characteristics
• Cortisone controlling the metabolism of carbohydrates and proteins 
• Gastrin, secretin and related hormones regulating various stages of digestion
• Estrogen developing secondary female sexual characteristics & maintaining pregnancy
• Glucagon raising blood glucose levels
• Oxytocin aka "cuddle hormone" causing contraction of some smooth muscles

Strange looking fruit in the cucumber and melon family, with spiky skin and very sharp thorns.
Also known as cucumis metuliferus, African horned melon, Kiwano, African horned cucumber, jelly melon, hedged gourd, melano, and blowfish fruit.
It is rich in anti-oxidants and  nutrients; water; high in  Vitamin C, Vitamin E, Potassium, Iron and Zinc. 

Root vegetable used as a spice or a sharp condiment made from the grated roots of Armoracia rusticana, syn. Cochlearia armoracia, a perennial plant of the Brassicaceae family, which also includes mustard, wasabi, broccoli, and cabbages. Often made into a sauce. 

Colorless odorless highly flammable gas, the lightest and most abundant element in the Universe. 
Hydrogen is used in the production of synthetic ammonia and methanol, in petroleum refining. It is added to fats and oils, such as peanut oil, through a process called hydrogenation.

Hydrogen is the most abundant element and is present in Earth’s atmosphere at about 0.5 ppm (parts per million). It is produced naturally by gut bacterial degradation of oligosaccharides and is present in human breath. Humans produce hydrogen at about 50 mg/day. Hydrogen is found in aircraft and space-shuttle air at about 100 ppm. 

Since its introduction as a diagnostic test in 1969 by Levitt and Calloway, the breath hydrogen test has gained in popularity for the diagnosis of intestinal disaccharidase deficiency (intolerance to lactose, fructose, or sucrose), being more sensitive than blood glucose based tests In selected conditions like celiac disease, it may be preferable to enzyme analysis of biopsy because it measures the response of the entire intestinal tract not just a small area which may not demonstrate enzyme deficiency in these cases. It is especially useful in blind loop syndrome (BLS), commonly referred to in the literature as small intestinal bacterial overgrowth (SIBO) or bacterial overgrowth syndrome (BOS). Diagnosis can be made if there is rise of more than 10 or 20 ppm after ingesting a certain substance.
Hydrogen could constitute from 0.000005 to 50% of human gas. 
The paper, published in 1969, found that: 'Flatus gases varied widely within dietary groups but much more gas was generated with diet S (Gemini-type: shrimp cocktail, chicken and vegetables, butterscotch pudding, apple sauce, etc) than with F (a bland formula). 
'In the first 12-hour collection, subjects fed S passed 3 to 209 ml of rectal H2 and 24 to 156 ml from the lungs.

​excessive, exaggerated or uncontrollable emotion (such as fear or panic) or excitement, especially among a group of people.

Increased heart rate or pulse is higher number of times a person's heart beats per minute. A normal heart rate depends on the individual, age, body size, heart conditions, whether the person is sitting or moving, medication use and even air temperature.
The usual range for resting heart rate is anywhere between 60 and 90 beats per minute. Generally, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness. For example, a well-trained athlete might have a normal resting heart rate closer to 40 beats a minute. Above 90 is considered high. Over 100 beats per minute is called tachycardia. This can cause dizziness, lightheadedness, or a fluttering in the chest. 

Foods, beverages or inhaled heat raising body temperature. 
Spicy dishes can produce a burning sensation when tasted, stimulating the circulation and raising internal body temperatures. So do liquids and solids  having a high degree of heat or a high temperature.
Victims of conflagration frequently sustain pulmonary injuries that are of equal or greater imlportance to survival than are the burns received on the surface of the body. At any given temperature moist air has more heat to give up than does an equal volume of dry air and is accordingly more likely to cause thermal injury of the respiratory tract. Inhalation of dry or moist hot air may destroy the upper tracheal mucosa without causing primary thermal injury of the lungs. when the original temperature of the air is high enough to produce almost instantaneous burning of the skin and upper respiratory mucosa.

Hemoglobin is the protein molecule in red blood cells that carries oxygen from the lungs to the body's tissues and returns carbon dioxide from the tissues back to the lung
Number of hemoglobin molecules per deciliter considered to be healthy is 13.5 to 17.5 grams per deciliter for men and 12.0 to 15.5 grams per deciliter  . for women,. For children, mean values are between 11 and 16.5 g/dL These reference ranges may differ from one medical practice to another depending on the individual laboratory, instruments, and methods.

Mild anemia is considered when hemoglobin is between 9.5 - 13.0 g/dL. Moderate anemia is considered when hemoglobin is between 8.0 - 9.5 g/dL. Severe anemia is considered for hemoglobin concentrations below 8.0 g/dL. Based on the available evidence, transfusion in the critically ill patient without active ischemic heart disease should generally be withheld until the hemoglobin level falls to 7 g/dl. The old 1030 rule (hemoglobin of 10 g/dl and a hematocrit levels falling below 30%) is now considered to be ill advised. The hemoglobin level at which serious morbidity or mortality occurs in critically ill patients with active ischemic heart disease is a subject of continued debate but it is likely that a set transfusion trigger will not provide an optimal risk–benefit profile in this population.

​A thick paste or spread made from ground chickpeas and sesame seeds, olive oil, lemon, and garlic. Hummus is rich in protein and while it can be high in fat, it is mostly heart-healthy unsaturated fat.

3-hydroxy-3-methylhexanoic acid (HMHA) is a branched fatty acid detected relatively in abundance in sweat. It has two enantiomers - right handed (R) and left-handed (L).
(+)-(S)-3-hydroxy-3-methylhexanoic acid - Armpit odor like and cumin spice like odor; also described by Hasegawa et. al. as having a strong spicy odor
(-)-(R)-3-hydroxy-3-methylhexanoic acid - Cumin spice like odor, weaker than racemic body; also described by Hasegawa et. al. as having a weak animalic odor.

Since the early 1990s, structurally unusual medium-chain (C6–C10) Volatile Fatty Acids (VFAs), in particular the trans (E) isomer of 3-methyl-2-hexenoic acid (3M2H), have been shown to contribute to underarm odor.  Subsequently, it was found that 3M2H, and the structurally related 3-hydroxy-3-methylhexanoic acid, are released by the action of a corynebacterial enzyme, Nα-acylglutamine aminoacylase, highly specific for the glutamine residue. A wide range of medium-chain VFAs are present in apocrine sweat released on skin by corynebacteria, with 3-hydroxy-3-methylhexanoic acid and 3M2H being the dominant species in terms of relative abundance.
Women have the potential to liberate significantly more (R)/(S)-3-methyl-3-sulfanylhexan-1-ol  - (R)/(S)-MSH. - which has a tropical fruit- and onion-like odor than (R)/(S)-3-hydroxy-3-methylhexanoic acid - (R)/(S)-HMHA - (possibly transformed into (E)/(Z)-3-methyl-2-hexenoic acid) that has a cheesy, rancid odor.
A fatty acid with one less Carbon - 2-Hydroxy-3-methylpentanoic acid generated by L-isoleucine metabolism is elevated in the urine and blood of patients with maple syrup urine disease, leading to a distinctive sugary maple syrup odor.
