    Harvesting & processing of cinnamon

    Cinnamon is an evergreen tree with oval-shaped leaves, thick bark and a berry fruit. While harvesting the spice, the bark and leaves are the main parts of the plant used. The harvesting includes cutting the shoots of the plant close to the ground. In processing, the shoots are first scraped with a semicircular blade and then rubbed with a brass rod to loosen the bark, which is split with a knife and peeled. The peels are telescoped one into another, forming a quill about 107 cm (42 inches) long and filled with trimmings of the same quality bark to maintain a cylindrical shape.

    After this process follows four or five days of drying and the quills are rolled on a board to tighten the filling . Again they are placed in subdued sunlight for further drying for a few days. Finally, they are bleached with sulfur dioxide and sorted into grades.

    Cinnamon is used as an aromatic condiment and flavouring additive in a wide variety of cuisines. The aroma and flavour of cinnamon is due to the presence of essential oil and principal component, cinnamaldehyde.

    Ground cinnamon is 11% water, 81% carbohydrates (including 53% dietary fiber), 4% protein and 1% fat.Since ancient times cinnamon has been in use as part of traditional medicine  primarily in Asian countries.

  •  Mindful eating helps your hormonal rhythm

    Does mindful eating help in improving your overall health? Does it have any advantage over binge eating? Research studies are ongoing on this topic as the role of mind in impacting physical health is becoming prominent day by day.

        Mindfulness is an ancient practice in which one’s thoughts, emotions, and physical sensations are directed at the present moment. It is becoming more aware of, rather than reacting to, one’s situation and choices.

    Mindfulness is neither focusing to improve concentration nor it is meditative process. Instead it is a feeling of awareness. Being “aware of the present moment “ is mindfulness.

       Mindful eating focuses on your eating experiences, body-related sensations, and thoughts and feelings about food, with heightened awareness and without judgment. In short it is listening to your food, its taste, aesthetic appeal, in the process of eating or chewing it.

            Health benefits of mindful eating  

    • Improved gut health

     Mindful eating helps to reduce bloating and gas as you enjoy food here and take enough time to chew it. Chewing helps to mix food with saliva and other gastric juices facilitating proper digestion. Therefore, the amount of undigested food in your gut will be reduced and fermentation process will be reduced. So bloating do not happen. Most of do hasty eating without proper chewing and digestion is delayed.

     It also helps to reduce constipation, diarrhoea, reflux and IBS like symptoms.

    • Proper absorption of nutrients

     Good digestion helps absorption of nutrients in the intestine and proper absorption of food aid in improving health of organs and body in general.

    • Helps weight loss

    Research studies have shown that mindful eating helps you eat less and feel more full.

    • Increased appreciation of food

    Only  if you love your food taking time it is appreciated well.

    Once  you start loving food  it makes your meal or dinner or snacking an enjoyable experience in your thoughts .

    • Stress reduction and hormonal well- being :

        When you slow down while eating and enjoy it as if in mindful eating ,you are naturally reducing your cortisol (stress hormone). This may help your body to protect itself from bad effects of stress like hormonal and autoimmune diseases, migraine, fertility issues and sexual dysfunctions.

    Some studies suggest that mindful eating helps to maintain a balanced hormonal rhythm.

    How to eat mindfully?

    ·       Take a few deep breaths and think how hungry you are.

    ·       As you cook food, notice its texture, smells and the sounds generated by the food prepared.

    ·       Put only the needed amount of food on your plate to satisfy your hunger.

    ·       Taste your food chewing it slowly and know the real taste, how it feels in your mouth, and how much you are enjoying it.

    ·       Try to note your hunger cues along the way.

    ·        Are you really still hungry after eating a quarter or half of your meal? Enjoy the meal but do not eat in such a way that your stomach is full.

    ·       Stop eating when you feel enough for quenching hunger, no matter how much food is left. Keep away the plate away from you.

  • Nutrition – to promote hair growth

    Nutrition plays a key role in the growth and repair of hair in human body. Many vitamins ,minerals and other nutrients are crucial for hair growth.

    Deficiencies of crucial nutrients lead to hair loss, although various other factors  also have been attributed as the causation of hair loss.

    A list of important nutrients for promoting hair growth as well as for preventing hair loss is listed below:

    Vitamin A influence hair growth cycle

    Vitamin A is a fat-soluble vitamin essential for the growth of healthy hair. However, it has been found that both deficiency and excess of vitamin A can cause hair loss.  Retinoic acid form of vitamin A helps to regulate hair follicle stem cells, influencing the functioning of the hair cycle.

    Beta-carotene or the pro vitamin A is also important to hair growth as beta-carotene is converted to vitamin A which helps growth of hairs.

    Pro vitamin A carotenoids are plant pigments that the body converts into vitamin A in the intestine. The main pro vitamin A carotenoids are beta-carotene, alpha-carotene, and beta-cryptoxanthin. Sources of provitamin A are leafy green vegetables, orange and yellow vegetables, tomato products, fruits, and some vegetable oils.

    Preformed vitamin A is found in foods from animal sources, including dairy products, eggs, fish, and meats.

    Vitamin B complex to nourish hair follicles

      B group vitamins particularly vitamins B1, B2, Niacin & Pantothenic acid play crucial role in hair growth. Reduced levels of thiamin (vitamin B1), riboflavin (vitamin B2), niacin, and pantothenic acid can contribute to the undernourishment of hair-follicle cells.

    Sources of B vitamins are Fortified breakfast cereals, fish beans, lentils, green peas, enriched or fortified cereals, breads, brown rice, sunflower seeds ,yogurt.

    Vitamin B5 (pantothenic acid) gives hair flexibility, strength and shine and helps prevent hair loss and greying.

    Pantothenic acid is found in a wide variety of foods like nuts, seeds, dairy milk, yogurt potatoes eggs, brown rice oats, broccoli,  fortified cereals ,organ meats (liver, kidney), beef, chicken breast,  mushrooms, avocado.

    Bacteria in the gut can also produce pantothenic acid to a small extent, although it is not adequate for bodily functions.

    The Recommended Dietary Allowance (RDA) of vitamin B5 for men and women is 5 mg daily. For pregnancy and lactation, the amount increases to 6 mg and 7 mg daily, respectively.

    Vitamin B12 to prevent hair loss

     Vitamin B12 helps prevent the loss of hair and can be found in fish, eggs, chicken and milk.

    Sources of vitamin B12 are:

    •     milk

    •     cheese

    •     yogurt

    •     meat

    •     fish-salmon, trout

    •     eggs

    •     clams

    •     shiitake mushroom

     Folic acid to boost hair follicle cell division and growth.

    Folic acid is important for hair growth as folic acid deficiency may contribute to decreased hair-follicle cell division and growth.

    Folic acid is also essential for the maintenance of healthy methionine amino acid levels in the body.

    The main dietary sources of folic acid are:

    o   tomato

    o   fresh fruits-oranges, grapefruit, papaya, banana, avocado

    o   turnip greens, spinach, romaine lettuce, asparagus, brussels sprouts, broccoli , mustard greens, green peas,

    o   cantaloupe

    o   beans

    o   peanuts

    o   sunflower seeds

    o   whole grains

    o   liver

    o   seafood

    o   eggs

    o   fortified foods and supplements

    o   crab

    o   hard-boiled egg

    o   beef liver

    Women  of reproductive age need 400 mcg of folic acid every day.

    Biotin for preserving hair strength, texture, and function.

     According to a study conducted at Harvard University biotin is one of the most important nutrients for preserving hair strength, texture, and function.

     Good food sources of biotin are eggs, liver and soy.

    Biotin from natural sources helps hair growth. However, biotin intake as a supplement for hair loss is not having any scientific evidence.

    People who are eating adequate amount of protein may not suffer from biotin deficiency; however vegans may be at risk.

     Vitamin C to build collagen for maintaining the strength of hair

     Vitamin C intake is crucial in patients with hair loss associated with iron deficiency as it plays an important role in the intestinal absorption of iron.

    Vitamin C helps to build collagen, which is vital for hair growth as well as for maintaining the strength of hair. Collagen plays a significant role in the health of the scalp and hair follicles.

    Collagen is the primary component of the dermis that contains hair follicles. Declining collagen levels associated with ageing may contribute to hair loss.

    The chief sources of vitamin C include :

    • Strawberries
    • Papaya
    • Potato
    • Broccoli
    • Kiwi fruit
    • Mangoes

    Vitamin D

    Vitamin D is linked with particular type of hair loss alopecia areata , in which hair is lost in circular spots. Vitamin D has crucial role in immune system functions and hence linked with an autoimmune disease alopecia areata.

     It is a vitamin you get from exposure to sun. Meat, fish,  milk, eggs and some oils are rich in vitamin D.

     Vitamin E to maintain the integrity of cell membranes of hair follicles

    Vitamin E is important to maintain the integrity of cell membranes of hair follicles. The vitamin also provides  stability to cell membranes and functions as an antioxidant while promoting healthy skin and hair.

    Vitamin E is an effective antioxidant  which fights  against free-radical damage causing hair loss.

     The chief sources of vitamin E include nuts and seeds, wheat germ oil, Sunflower, safflower, and soybean oil, sunflower seeds, almonds, avocado, peanuts, peanut butter, beet greens, collard greens, spinach & pumpkin.

     Amino acids

    Amino acids  L-methionine and L- cystein  play a vital role in hair health. Proteins are the major sources of amino acids.

    L-Methionine, one of four sulfur-containing amino acids, supports hair strength by providing adequate amounts of sulfur to hair cells.

    L-Cystein – supports hair strength providing sulphur.

    The main sources of methionine are animal products as they contain all the essential amino acids and include meat, fish, poultry, eggs, and dairy products. The plant sources are sunflower seeds, tofu, edamame, black beans, refried beans, cashews.

    Proteins for hair growth

    Proteins play a significant role in the growth as well as in the maintenance of strength of hair. The daily requirement is 0.83 g/kg BW.

    Sources of healthy proteins:

    • Lean meat
    • Eggs
    • Soy products.
    • Legumes, which include beans and peas
    • Nuts & seeds
    • Dairy products, such as milk, cheese, and yogurt.
    • Whole grains
    • Vegetables

     Minerals for maintaining healthy hair

     A few minerals including iron, magnesium, sulfur, silica, selenium and zinc are also very important for maintaining healthy hair.

    Selenium helps in protecting the hair from oxidative damage . It also helps  in hair follicle morphogenesis. The mineral is involved in hair growth and is needed by the body for regulating and activating thyroid hormones, imbalances of which can lead to hair fall. Liver, fish, eggs, whole grains, meat, fish, nuts etc. are excellent sources of selenium.

    Iron also play a vital role in hair loss prevention. Telogen effluvium is a type of excessive amount of hair loss related to deficiency of iron. It is essential to ensure the intake of iron, and maintain adequate amounts of serum ferritin [iron storage in the body]. Consume more leafy vegetables, beans such as red kidney beans and chickpeas, seafood etc.

     Iodine is important for the production of thyroid hormones. Variations in thyroid hormone levels can lead to hair thinning and hair loss. Main sources of iodine are seaweed (nori, kelp, kombu, wakame),fish, shellfish (cod, canned tuna, oysters, shrimp, iodized table salts ,dairy (milk, cheese, yogurt)eggs, beef liver, chicken.

    Omega 3 fatty acids for  hair growth and maintenance of follicular health.

    Omega 3 fatty acids also have a significant role in hair growth and maintenance of scalp and hair follicular health. The essential omega-3 fatty acids found in fish sources, prevent a dry scalp and dull hair color.

    Most important sources of omega 3 fatty acids are walnuts, chia seeds, flax seeds, fish oil, flaxseed oil etc. These are vital nutrients that support the health of hair follicles.

        For the healthy growth of your hair include foods rich in all the essential nutrients or take supplements under the directions from your doctor depending on the degree of nutrient deficiency in your body .Diet has a key role in hair loss treatment also.

  • Eye exercises for digital eye strain

    Do your eyes feel strained after working with computer or mobile screen for long? it is high time that you should take measures to prevent digital eye strain.

    Digital eye strain is of late a common problem affecting all age groups from children to adults across the world.

     Computer vision syndrome is commonly referred to as digital eye strain, and it includes a group of symptoms related to eyes and vision resulting from prolonged usage of computer, tablet, and cell phones.

    Prolonged exposure to digital gadget screens causes eye discomfort and vision problems and the level of discomfort increases with duration of exposure.

    What is the cause of digital eye strain?

    Your eyes get fatigued by constant and prolonged exposure to digital screens of devices and gadgets. Increased screen time compels your eyes work harder in unusual ways and predispose many individuals to develop vision-related symptoms.

     Furthermore, a few pre- existing vision problems in people, including far sightedness, astigmatism, age related vision changes [ presbyopia ]  complicate the computer vision syndrome or worsen it.

    During your digital interaction with a mobile or computer screen the work your eye muscles and other cells and tissues do is entirely different from that done while reading a book. Often the letters on the computer or handheld device are not as precise or sharply defined, the level of contrast of the letters to the background is reduced, and the presence of glare and reflections on the screen may make viewing difficult.

    Moreover, the sitting posture and distance to screen and exposure time to screen also affect the focus and eyesight.

    Thus, the eye focusing and eye movement requirements for digital screen viewing can place additional demands on the visual system.

    Uncorrected or under corrected vision problems can be major contributing factors to computer-related eyestrain. It is not uncommon that people who have an eyeglass or contact lens prescription may find it’s not suitable for the specific viewing distances of their computer screen.

    Symptoms of digital eye strain

    The most common symptoms of digital eyestrain include:

    • Eyestrain.
    • Headaches.
    • Blurred vision.
    • Dry eyes.
    • Neck and shoulder pain.

    There are various factors accounting to these symptoms including:

    Poor lighting.

    Poor seating posture.

    Uncorrected vision problems.

    Glare on a digital screen.

    Improper viewing distances.

    Mostly multiple factors synergistically operate to cause these symptoms in people of all age groups.

    How digital eye strain is detected?

    There are many tests and processes to find out it.

    You may check your vision and other symptoms consulting with an ophthalmologist. Sometimes this problem may need preventive as well as curative treatment.

    The common processes done here include

    • History taking.
    • Visual acuity tests are routinely done to assess the extent to which vision may be affected.
    • Assessment to determine the appropriate lens power needed to compensate for any refractive errors (nearsightedness, farsightedness or astigmatism) also is done.
    • Testing how the eyes focus, move and work together is important in order to obtain a clear, single image of what is being viewed by the eyes. It must effectively change focus, move and work in unison. This testing will look for problems that keep the eyes from focusing effectively or make it difficult to use both eyes together.

    Eye exercise for reducing digital eye strain

    1. Focusing exercise

    Hold your pointer finger a few inches away from your eye.

    Focus on your finger.

    Slowly move your finger away from your face, holding your focus.

    Look away for a moment, into the distance.

    Focus on your outstretched finger and slowly bring it back toward your eye.

    Look away and focus on something in the distance.

    • Near and far vision exercises

    Hold your thumb about 10 inches from your face and focus on it for 15 seconds.

    Find an object roughly 10 to 20 feet away and focus on it for 15 seconds.

    Return your focus to your thumb.

    3.Figure eight exercise

    This exercise needs to be done from a seated position.

    Choose  a point on the floor about 10 feet in front of your eyes and focus on it.

    Trace an imaginary figure eight with your eyes here.

     Do tracing for 30 seconds, then switch directions.

    • The 20-20-20 rule

    Eyestrain is a problem for many people as they continuously focus eyes on bright screen light .

    If you work at a computer  for a long period of time, the 20-20-20 rule may help prevent digital eyestrain.

    How to apply this 20-20 rules for the well-being  of your eyes?

     To implement this rule, every 20 minutes, look at something 20 feet away for 20 seconds.

    Many of the visual symptoms experienced by users are only temporary and will decline after stopping computer work or use of the digital device. However, some individuals may experience continued reduced eye sight  such as blurred distance vision, even after stopping work at a computer.

    Can exercise alone help your eye health?

    These self-help eye exercise programs may help you improve your eye strain and fatigue. But no scientific data support it.  However , experiences show that it helps to reduce eye fatigue.

     A ophthalmologist’s help may be needed for prescribing the correct glasses for  your nearsightedness, farsightedness, presbyopia, or astigmatism.

     Similarly eye exercises do absolutely nothing for glaucoma or macular degeneration — serious diseases that require professional medical help.

    Eyeglasses or contact lenses prescribed for general use may not be adequate for computer work. Lenses prescribed to meet the unique visual demands of computer viewing may be needed.

    Special lens designs, lens powers or lens tints or coatings may help to maximize visual abilities and comfort.

     Better body posture and positioning of computer helps to reduce digital eye strain

    Proper body positioning , lighting conditions, chair comfort, location of reference materials, the position of the monitor, and the use of rest breaks play crucial role in reducing digital eye strain.

    Location of the computer screen is very important. Most people find it more comfortable to view a computer when the eyes are looking downward. Optimally, the computer screen should be 15 to 20 degrees below eye level (about 4 or 5 inches) as measured from the center of the screen and 20 to 28 inches from the eyes.

    Reference materials.

     These materials should be ideally placed above the keyboard and below the monitor. Otherwise, a document holder can be used beside the monitor. Here the goal is to position the documents at eye levels, so the head does not need to be repositioned from the document to the screen.

    Lighting

     Position the computer screen in such a way to avoid glare, particularly from overhead lighting or windows.

    Use blinds or drapes on windows and replace the light bulbs in desk lamps with bulbs of lower wattage.

    Anti-glare screens also can be used. If there is no way to minimize glare from light sources, consider using a screen glare filter. These filters decrease the amount of light reflected from the screen.

    Seating position

     Use a comfortably padded a conform to the body. Chair height should be adjusted so the feet rest flat on the floor. Arms should be adjusted to provide support while typing and wrists shouldn’t rest on the keyboard when typing.

    Rest breaks.

    Give rest to eyes when using the computer for long periods. Resting the eyes for 15 minutes after two hours of continuous computer use. Also, for every 20 minutes of computer viewing, look into the distance for 20 seconds to allow the eyes a chance to refocus.

    Blinking.

     Blink frequently to reduce dryness of eyes when using a computer.Blinking helps to keep your eye moist.

    Regular eye examinations and proper viewing habits can help to prevent or reduce the development of the symptoms associated with CVS.

    How to prevent digital eye strain?

    • Use appropriate spectacles or glasses which suits your work and vision.
    • People may be benefitted from one of the new lens designs made specifically for computer work.
    • Minimize discomfort from blue light and glare. Blue light from LED and fluorescent lighting, as well as monitors, tablets and mobile devices, can negatively affect vision over the long term. Special lens tints and coatings can reduce the harmful impact of blue light.
    • Minimize glare on the computer screen by using a glare reduction filter, repositioning the screen or using drapes, shades or blinds.
    • Keep your computer and mobile screen dirt-free and removing fingerprints on it for better clarity.
    • Adjust work area and computer for comfort. When using computers, most people prefer a work surface height of about 26 inches. Desks and tables are usually 29 inches high. Place the computer screen 16 to 30 inches away. The top of the screen should be slightly below horizontal eye level. Tilt the top of the screen away at a 10- to 20-degree angle.
    • Use an adjustable document holder. Place reference material at the same distance from eyes as the computer screen and adjacent to it. This may help the eyes to avoid changing focus when looking from one to the other.

     In a nut shell, follow healthy habits to improve vision reducing digital eye strain. Consult your ophthalmologist if you have any kind of vision problems and use the right kind of lenses. At the same time discuss with your ophthalmologist about the nature of your work, particularly if you use computer for the entire day. If glasses are worn for distant vision, reading or both, they may not provide the most efficient vision for viewing a computer screen, which is about 20 to 30 inches from the eyes. Tell the doctor about job tasks and measure on-the-job sight distances.  If you provide the accurate information to your doctor or optometrist it will help, get the best vision improvement.
