Bioactive compounds
It comprises 57% of total fatty acid. Metabolism of ALA:-1. It can undergo β-oxidation to produce energy.2. It can be recycled to make other fatty acids.3. It can serve as a substrate for ketogenesis, the process of
making ketone bodies.4. It can be stored in adipose tissue for later use.5. It can be incorporated into the phospholipids of cell
membranes, where it affects membrane activities; and6. It can be converted to long chain fatty acids like
eicopentaeonic acid (EPA), docosapentaeonic acid (DPA) and docosahexaenoic acid (DHA), which have important function in many types of cells and organs.

Proteins
Flax is richest source of lignans: having approximately 800 times more lignan than other plant source.
They have estrogen like action in human. Flax rich in: secoisolariciresinol diglucoside (SDG) Flax contain other lignan such as : metairesional, pinoresinol,
lariciresional, isolariciresional and secoisolariciresinol (SECO)
Plant lignans are converted by bacteria to mammalian lignan : enterodiol and enterolactone
smeds et al., 2007
Lignans
provide health benefits due to their weak estrogenic or anti estrogenic; as well as stroke incidence, blood platelet aggregation, oxygen scavenging free radicals in blood and vascular smooth muscle proliferation.
They have:o Highly antioxidanto anticancer and antiviral effects o influence gene expression (activation) and o Prevent from estrogen-related diseases such as
osteoporosis, reduce breast cancer, prostrate cancer, postmenopausal symptoms.
Enterodiol and Enterolactone
Flax contain 28% dietary fibers1. Insoluble: 75%• Cellulose, hemi cellulose and lignin2. soluble: 25%• Mucilage gums
Dietary fibers
Good source of calcium, magnesium, potassium, zinc, and E,K,B vitamins
o Vitamin E (tocopherol) is found in good quantity. • protects cell proteins and fats from oxidation• promotes sodium excretion in the urine• which may help lower blood pressure• helps lower the risk of heart disease, and• some types of cancer and Alzheimer disease Carbohydrates: low in carbohydrates• About 1g per 100 g of flax mercier et al.,

Vitamin, minerals and Carbohydrates
Nutaceuticals : a nutraceutical is a
product isolated or purified from foods that is generally sold in medicinal forms, not usually associated with foods.
Functional food: which is similar in
appearance to a conventional food, consumed as a part of the usual diet, with demonstrated physiological benefits, and/or to reduce the risk of chronic disease beyond basic nutritional functions
Flax is Nutraceuticals or Functional food
Flaxseed has potential health benefits besides the nutrition, due to mainly 3 reasons:
1. due to its high content of ω-3 α- linolenic acid;
2. being rich in dietary soluble and insoluble fibers; and
3. due to its high content of lignans, acting as anti-oxidants and phytoestrogens.

Control on hypertensive Protection against cancer and diabetes Control on dyslipidemia Reduce breast cancer growth Effect on postmenopausal women symptons
In CVDs In diabetes In cancer Bone metabolism Kidney diseases Constipation Menopause disorder Insomania Celiac diseases Memory Skin diseases
Some diseases in which flax is helpful
1. hormone related: lignan inhibits the
aromatase which stop the production of estrogen in postmenopausal women, have become useful in the management of patients with breast cancer whose lesion was found to be estrogen receptor positive
2. non hormone related: Flax decrease cell
proliferation; production of prostaglandin, production of eicosanoid, production of growth factor like VEGF
Flax also increase cell apoptosis
Flax lignan have anti oxidant effect
Cancer flax act on cancer by 2 ways
Flax seed is a low glycaemic food (G.I 32) and helps stabilize blood sugar levels for longer.
Omega-3 have anti inflammatory properties. Fibers : slow down the absorption of glucose. Low carbohydrate level
In treatment of diabetes
Bone metabolism Phytoestrogens may help prevent
osteoporosis. ALA may help prevent bone loss and
osteoporosis by blocking the production of cytokines, especially tumor necrosis factor α (TNF-α).
Constipation Mucilage gums are polysaccharides that
become viscous when mixed with water or other fluids and have an important role in laxatives.
Insoluble fiber helps improve laxation and prevent constipation, mainly by increasing fecal bulk and reducing bowel transit time
For hair and skin• Omega 3 help in healing the wound• It also provide hydration to skin • Flaxseed oil is also beneficial for hair by reducing the hair loss, hair loss is caused by DHT.
Insomnia Omega 3 and tryptophan helps in boosting serotonin
(sleep regulating compound) levels in blood. Magnesium also helps in overcoming anxiety, stress
and depression, thus enhancing sleep.
Celiac disease • Flax is gluten-free.• dietary gluten irritates the mucosal lining of the gastrointestinal tract.• who are sensitive to gluten enjoy the flax.
IMMUNITY BOOSTER
The omega 3 fatty acids from Alpha Linolenic Acid and the protective antioxidants called lignans, can work together to enhance the immune response, or to tone it down if it is in hyper mode.
STRESS & DEPRESSION
The Alpha Linolenic Acid (ALA) in flax seed is the source of the Omega 3 fatty acids. A key one is Docosahexaenoic Acid (DHA). This fatty acid is crucial to brain function, and is often deficient in modern people. DHA is important for brain development in children, for calming in the face of stress, for mental acuity, and for memory. Having enough of it makes one calmer and smarter, and it may prevent the development of dementia, or Alzheimer's disease.
After menopause, the levels of endogenous estrogens in the blood decrease naturally because the ovaries release less natural estrogens. In this case, the lignans act like weak estrogens.
Phytoestrogens are similar to natural or synthetic estrogen and
Thus used as hormones therapy. So helpful in postmenopausal symptoms
such as vaginal dryness, itching, hot flashes.
In postmenopausal symptoms
Use of whole flax in products for human consumption Bread Cereals Crackers Meal oil Omega-3 eggs Pasta Snacks Waffles Pet food
How to add flaxseed in diet FLAX IN HOME COOKING Flax can be added to your cooking in its milled or whole
seed form. Whole flax seeds – The small, reddish-brown seeds of flax
add nutrition when added to bread dough, pancake, muffin or cookie mixes. When sprinkled on top of any of these before baking, they also add crunch, taste and eye appeal.
Milled flax – Grind a desired amount of flax seeds to a free-flowing granular consistency in a coffee bean grinder. Added to any foods, the milled flax enhances the flavour, appearance and food value of the finished product.
Flax Replaces Oils - Flax seeds can replace the oil or shortening in a recipe because of its high oil content. If a recipe calls for 1/3 c of oil, use 1 c of milled flax to replace the oil — a 3:1 substitution ratio. When flax is used instead of oil, baked goods tend to brown more rapidly.
Flax form Consumed PREPARATION/PROCESSING METHOD
Health benefits
Flaxseed tea Uncrushed flaxseed are soaked in water for 30 min. seeds are then removed while the water is warmed moderately
Useful against dyspnoea, asthma, dysphonia, bad cough and bronchitis
Flaxseed Drink
A teaspoon of flaxseed powder is put into a glass of hot water, brewed and drained. A cup of this water is to taken daily
Helps out constipation
Flaxseed Flour
Source :- (Moghaddasi , 2011)
Flaxseed flour 10-gram each for the concerned ailment is given a paste like consistency using honey, 30-40 g of this paste is swallowed on an empty stomach in the morning
Used against pulmonary tuberculosis, haemoptys-is, splenomegaly and stomach ulcer.
Disinfects gastrointestinal Cures inflammation of intestines and abdominal pains.
Strengthens the memory. Protect the skin against dry. Used in eczema and psoriasis Curing of mental disorder Treat respiratory diseases Cure bad cough.
Cyanogenic Glycosides• flaxseeds contain cyanogenic compounds
that break down into isothiocyanates, which are considered goitrogenic.
Allergic reaction: like nausea, vomitting.
Safety of flax

Recommended doses in various diseases
flaxseeds are the richest source of α-linolenic acid and lignans. The role of flaxseed lignans and ω-3 fatty acid in reducing the
risks associated with cardiac and coronary disease, cancer (breast, colon, ovary and prostate) and other human health risk factors has been well known.
flax and flaxseed oil may be preferred ingredients of functional foods and nutraceuticals in future. There is no doubt that a change to an omega-3 rich and high fiber diet would be beneficial.
Therefore the use of flaxseed in whole seed or ground form can be recommended as a dietary supplement
enrichment of diets of the animals with flax/flaxseed oil for production of ω-3 enriched eggs, milk, meat and other animal origin products could be another approach in utilizing flaxseeds.
