"Retinol" int 671 Retinol, also known as Vitamin A1, is a vitamin found in food and used as a dietary supplement. As a supplement it is used to treat and prevent vitamin A deficiency. Measured in micrograms (mcg).
"Manganese" float 0.0 Manganese is a chemical element with symbol Mn and atomic number 25. In biology, manganese(II) ions function as cofactors for a large variety of enzymes with many functions. Manganese enzymes are particularly essential in detoxification of superoxide free radicals in organisms that must deal with elemental oxygen. Manganese also functions in the oxygen-evolving complex of photosynthetic plants. The element is a required trace mineral for all known living organisms but is a neurotoxin. In larger amounts, and apparently with far greater effectiveness through inhalation, it can cause a poisoning in mammals with neurological damage that is sometimes irreversible. Measured in milligrams (mg).
"Beta Cryptoxanthin" int 0 Cryptoxanthin is a natural carotenoid pigment. It has been isolated from a variety of sources including the petals and flowers of plants in the genus Physalis, orange rind, papaya, egg yolk, butter, apples, and bovine blood serum. In the human body, cryptoxanthin is converted to vitamin A (retinol) and is, therefore, considered a provitamin A. As with other carotenoids, cryptoxanthin is an antioxidant and may help prevent free radical damage to cells and DNA, as well as stimulate the repair of oxidative damage to DNA. Measured in micrograms (mcg).
"Riboflavin" float 0.034 Riboflavin, also known as vitamin B2, is a vitamin found in food and used as a dietary supplement. It is nearly always well tolerated. Normal doses are safe during pregnancy. Riboflavin is in the vitamin B group. It is required by the body for cellular respiration. Food sources include eggs, green vegetables, milk, and meat. Measured in milligrams (mg).
"Cholesterol" int 215 An organic molecule that is a sterol (or modified steroid), a type of lipid molecule, and is biosynthesized by all animal cells, because it is an essential structural component of all animal cell membranes; essential to maintain both membrane structural integrity and fluidity. Cholesterol enables animal cells to dispense with a cell wall (to protect membrane integrity and cell viability), thereby allowing animal cells to change shape and animals to move (unlike bacteria and plant cells, which are restricted by their cell walls). Since all animal cells manufacture cholesterol, all animal-based foods contain cholesterol in varying amounts. Measured in milligrams (mg).
"Lutein and Zeaxanthin" int 0 Lutein is synthesized only by plants and like other xanthophylls is found in high quantities in green leafy vegetables such as spinach, kale and yellow carrots. Zeaxanthin is one of the most common carotenoid alcohols found in nature. It is important in the xanthophyll cycle. Synthesized in plants and some micro-organisms, it is the pigment that gives paprika (made from bell peppers), corn, saffron, wolfberries, and many other plants and microbes their characteristic color. This combined quantity of these two compounds is measured in micrograms (mcg).
"Carbohydrate" float 0.06 In food science and in many informal contexts, the term carbohydrate often means any food that is particularly rich in the complex carbohydrate starch (such as cereals, bread and pasta) or simple carbohydrates, such as sugar (found in candy, jams, and desserts). Carbohydrates are found in wide variety of foods. The important sources are cereals (wheat, maize, rice), potatoes, sugarcane, fruits, table sugar(sucrose), bread, milk, etc. Starch and sugar are the important carbohydrates in our diet. Starch is abundant in potatoes, maize, rice and other cereals. Sugar appears in our diet mainly as sucrose(table sugar) which is added to drinks and many prepared foods such as jam, biscuits and cakes. Glucose and fructose are found naturally in many fruits and some vegetables. Glycogen is carbohydrate found in the liver and muscles (as animal source). Cellulose in the cell wall of all plant tissue is a carbohydrate. It is important in our diet as fibre which helps to maintain a healthy digestive system. Measured in grams (g) by difference.
"Kilocalories" int 717 The total number of kilocalories in this food item. A kilocalorie is a unit of energy of 1000 calories (equal to 1 large calorie).
"Alpha Carotene" int 0 Alpha Carotene is a form of carotene with a Beta-ionone ring at one end and an Alpha-ionone ring at the opposite end. It is the second most common form of carotene. Alpha Carotene is common in yellow-orange and dark-green vegetables. Measured in micrograms (mcg).
"Sugar Total" float 0.059999999 Sugar is the generalized name for sweet, short-chain, soluble carbohydrates, many of which are used in food. They are composed of carbon, hydrogen, and oxygen. There are various types of sugar derived from different sources. Simple sugars are called monosaccharides and include glucose (also known as dextrose), fructose, and galactose. The table or granulated sugar most customarily used as food is sucrose, a disaccharide. (In the body, sucrose hydrolyses into fructose and glucose.) Other disaccharides include maltose and lactose. Longer chains of sugars are called oligosaccharides. Chemically-different substances may also have a sweet taste, but are not classified as sugars. Some are used as lower-calorie food substitutes for sugar, described as artificial sweeteners. Measure in grams (g).
"Protein" float 0.85 Proteins are essential nutrients for the human body. They are one of the building blocks of body tissue, and can also serve as a fuel source. As a fuel, proteins provide as much energy density as carbohydrates: 4 kcal (17 kJ) per gram; in contrast, lipids provide 9 kcal (37 kJ) per gram. There are nine essential amino acids which humans must obtain from their diet in order to prevent protein-energy malnutrition and resulting death. Humans need the essential amino acids in certain ratios. Dietary sources of protein include both animals and plants: meats, dairy products, fish and eggs as well as grains, legumes and nuts. Measured in grams (g).

"Copper" float 0.0 Copper is an essential trace element that is vital to the health of all living things (humans, plants, animals, and microorganisms). In humans, copper is essential to the proper functioning of organs and metabolic processes. Measured in milligrams (mg).
"Zinc" float 0.09 Zinc is found in cells throughout the body. It is needed for the body's defensive (immune) system to properly work. It plays a role in cell division, cell growth, wound healing, and the breakdown of carbohydrates. Zinc is also needed for the senses of smell and taste. Measured in milligrams (mg).
"Sodium" int 576 Salt, also known as sodium chloride, is about 40 percent sodium and 60 percent chloride. It adds flavor to food and is also used as a preservative, binder, and stabilizer. The human body needs a very small amount of sodium - the primary element we get from salt - to conduct nerve impulses, contract and relax muscles, and maintain the proper balance of water and minerals. But too much sodium in the diet can lead to high blood pressure, heart disease, and stroke. Measured in milligrams (mg).
"Potassium" int 24 Potassium is a mineral and electrolyte that helps nerves to function and muscles to contract, among many other tasks. Potassium sources include leafy greens, fruit from vines, root vegetables, and citrus fruits. Measured in milligrams (mg).
"Calcium" int 24 Calcium is a mineral needed to build and maintain strong bones and teeth. It is also very important for other physical functions, such as muscle control and blood circulation. Calcium is not made in the body - it must be absorbed from food. To effectively absorb calcium from food, Vitamin D is needed. Measured in milligrams (mg).
"Magnesium" int 2 Magnesium is an essential mineral for human nutrition. Magnesium is needed for more than 300 biochemical reactions in the body. It helps to maintain normal nerve and muscle function, supports a healthy immune system, keeps the heart beat steady, and helps bones remain strong. It also helps regulate blood glucose levels and aid in the production of energy and protein. There is ongoing research into the role of magnesium in preventing and managing disorders such as high blood pressure, heart disease, and diabetes. However, taking magnesium supplements is not currently recommended. Diets high in protein, calcium, or vitamin D will increase the need for magnesium. Most dietary magnesium comes from vegetables, such as dark green, leafy vegetables. Measured in milligrams (mg).
"Iron" float 0.02 Iron is a mineral that is naturally present in many foods, added to some food products, and available as a dietary supplement. Dietary iron has two main forms: heme and nonheme. Plants and iron-fortified foods contain nonheme iron only, whereas meat, seafood, and poultry contain both heme and nonheme iron. Measured in milligrams (mg).
"Phosphorus" int 24 Phosphorus is an essential macromineral, included in almost all foods. Phosphorus is the second most abundant mineral nutrient in the body, after calcium. This mineral is part of all cells, especially cell membranes, and is essential to bone strength, because it's the main structural component of bones and teeth, as calcium phosphate. Phosphorus is also an important element in energy production. Measured in milligrams (mg).
