National Nutrition Week is celebrated from September 1 to 7 every year. Nutrition is the focal point of health and well-being. In other words, it allows you to be strong, provides you with the energy to do the things you want to do, and makes you look and feel your best.
Battling hypertension, cancer, diabetes, a weak heart or kidneys ? Right nutrition plays a key role.
For a strong, healthy body and a happy mind, nutrition plays a pivotal part ,not just as prevention, but as a tool for speedy recovery as well.
The theme for this year is ‘On the steps of nutrition lies the emancipation of the next generation - This is our vision and conviction’. The theme intends to address malnutrition and to generate awareness to tackle the problem through the existing health care delivery system by formulating strategies, policies and plans of action, thereby improving the nutritional status of the community.
Today, there is a wealth of nutrition information at the finger tips — from diet books to newspaper articles, everyone seems to have an opinion about what one should be eating.
The underlying objectives behind this nation- wide celebration are to create awareness among the general public, especially mothers, regarding the importance of food and nutrition in our day to day life thereby improving the Nutritional Status of the people. The programme also highlights the efforts of the Government to improve the Nutritional Status of the people.
The celebration during this week will include
* Exhibition on Health and Nutrition.
* Nutrition Education Demonstration programme.
* Skit/Slogan/Painting competition for schoolchildren.
* Quiz Competition for mothers and adolescent girls.
* Recipe Competition on nutritious food.
These suggestions from our diet experts will innovate the way you cook and look, health guaranteed:
Incorporate Whole Grains: There is broad spectrum of whole grains that you can choose from; brown rice, whole wheat, bulgar/ dalia (broken wheat), rye, oats, and bran. Besides fiber, your plate will provide you more Vitamin B, zinc and selenium.
Ensure a Colorful Plate: Bright richly colored fruits and vegetables contain more nutrients and antioxidants. Brightly colored foods like carrots, beetroots, green leafy vegetables papayas, mangoes, tomatoes are a good source of carotenoids, a form of vitamin A that may help prevent vision troubles, heart disease and even cancers.
Avoid Packaged and Processed Foods: Besides added salt and preservatives, you are not benefitting from any ready-to-eat meals. You are exposing your family to health barriers like hypertension, bad digestion, excess calories and malnourishment.
Cook Fresh: Fresh is best. Freshly cooked meals are the healthiest in terms of vitamin and nutrient content. Cook with seasonal, farm fresh, preferably organic produce. Frozen, canned vegetables, although still healthy, should be a last choice because many of the C and B vitamins are destroyed in the cooking process.
Don’t Throw Away the Water: All experts enforce the concept that most benefit is attained from your fruits and veggies if you eat them raw. If you cook them, choose steaming rather than boiling, so you don’t lose the vitamins in the cooking water. Diet experts are particular about reusing vegetable cooking water -- Water that remains from steaming or boiling, to retain some of the vitamins that were lost. Do not throw away water after boiling rice or potatoes/vegetables, instead use it when making gravy/dals.
Some more healthy quick tips
* Make breakfast cereal healthy with sliced bananas or almonds.
* Blend some fresh fruit, yogurt, for a wholesome breakfast smoothie.
* Cook a healthy egg by whipping chopped vegetables like spinach, mushrooms, and green peppers to an omelet.
* Enjoy a piece of fresh fruits with your lunch or as a snack.
* Add a green salad to your evening meal. Adding onion, tomato, raw mango, cabbage, cucumber, capsicum or olives can make it more interesting.
* Use loads of vegetables as a topping for easy meals. Keep some nuts handy as an energy-rich snack.
* Learn to cook healthy for your family with a wide choice of healthy recipes.
This September, try and improve the way your family eats. Encourage more nutrition -wise shopping and see the difference in self and your family’s stamina as well as endurance levels.

General guide lines for dietary management for sports persons with Type1 diabetes...
M.V Hospital for Diabetes, Royapuram
Can people with Type1 diabetes seriously think about taking part in a major event such as the Olympics?
Type 1 diabetes is a condition in which the body is unable to produce insulin. Without insulin, the body's ability to use glucose as a fuel source is impaired. That does not mean that people with Type 1 diabetes have to give up their dreams of a successful sports career. Pakistani batsman and fast bowler Imran Khan and swimmer Gary Hall Jr. are just a few athletes with Type 1 diabetes who have competed at the highest level of demanding sports. With good management, it is possible to participate in sporting activities with this condition.
Why is insulin important?
Insulin is a hormone produced in the pancreas. It has a number of important functions in the body, including a regulatory effect on carbohydrate metabolism.
Insulin stimulates body cells to take up glucose and use it for fuel.
It inhibits the release of glucose from glycogen in the liver and stimulates the synthesis of muscle glycogen after exercise.
In the absence of diabetes, insulin is released according to the body's needs and the concentration of glucose in the blood is kept within a tight range.
People with Type 1 diabetes do not produce insulin and so the body is unable to use glucose properly as a fuel source and starts to rely on fat and protein as fuel. This causes blood glucose levels to rise excessively and toxic by-products from fat breakdown (ketones) to build up in the blood. . Therefore, regular insulin injections are needed to simulate what the pancreas would be doing if it could make insulin.
The amount and timing of insulin administration needs to be matched to factors such as food intake, individual metabolism and activity level.
How does exercise affect diabetes management?
Factors such as muscle contraction, increased blood flow and increased body temperature cause the body to be more responsive or 'sensitive' to insulin during and soon after exercise. When muscles contract, they can also independently absorb glucose from the bloodstream.
Therefore, in people who do not have diabetes, insulin release decreases during exercise. People with Type 1 diabetes usually need to adjust their insulin dose to account for a reduced requirement for insulin during exercise.
Management of diabetes varies for each individual. Regular monitoring of blood glucose concentrations and trial and error (under the supervision of your diabetes specialist) is needed to understand and manage each individual's response to exercise.
How does Type 1 diabetes affect sport nutrition strategies?
General sports nutrition strategies are similar whether or not you have diabetes. Managing Type 1 diabetes and competing successfully requires a commitment to trials of different food and fluid combinations in and around exercise. It is impossible to provide a single set of guidelines that will suit all people with Type 1 diabetes. Here are some guidelines to consider. You will need to work with your diabetes specialist and dietitian and use trial and error to find the best approach for you.
Effect of diabetes on dietary needs...
Blood glucose control in athletes with Type 1 diabetes is usually better when exercise patterns and eating patterns, including meals and snacks, are consistent. In general, athletes with diabetes have the same dietary requirements as athletes without the condition- plenty of vegetables, fruit, beans, breads, and cereals; moderate amounts of fish, meat, poultry, eggs, and dairy products; and smaller amounts of refined sugar, alcohol, and foods high in fat.
Needs for energy, carbohydrates, protein, and fat are as follows:
* Athletes with Type 1 diabetes need to consume enough food for energy in order to stay healthy, maintain a desirable body weight, and train and compete effectively. This includes making adjustments when the intensity and/or duration of exercise changes.
*Carbohydrates are needed on a daily basis to maintain blood glucose levels and to replace glycogen stores. The recommended range for athletes is typically 2.7–4.5 grams/lb (6–10 grams/kg).
* Protein intake recommendation for both endurance and strength athletes with diabetes is 0.5–0.8 grams/lb (1.2–1.7 grams/kg).
* After carbohydrate and protein needs are met, healthy sources of fat can provide the remaining caloric needs. Healthier sources of fat include monounsaturated and polyunsaturated fats from plants, such as vegetable oils, nuts, seeds, and avocados.
Carbohydrate-containing foods with a low glycemic index can assist with blood glucose control. Glycemic index is a tool used to rank foods according to their immediate effect on blood glucose levels. Carb-containing foods that are broken down quickly are also called high glycemic index foods and will rapidly release glucose into the bloodstream. Those that break down slowly are known as low glycemic index foods and release glucose into the bloodstream gradually. The latter can be advantageous for people with diabetes.
Examples of low glycemic index foods include:
* Fresh fruit — apples, bananas, pears, and grapes
* Breads and cereals made with whole grains
* Whole-grain hot cereals such as oatmeal
* Whole-grain pasta
Selecting healthy foods and monitoring food portions are important tools in managing blood glucose levels.
Eating After Training and Competition...
General sports nutrition recovery strategies are the same as for non-diabetic athletes. Fuel and fluid used during exercise need to be replaced. The increased insulin sensitivity caused by exercise lasts for several hours after exercise. Therefore the risk of hypoglycemia persists for some time. Delayed hypoglycemia can occur 4-48 hours after exercise.
Delayed hypoglycemia can be prevented by consuming sufficient carbohydrate before, during and after exercise. It may also be necessary to reduce the next insulin dose after exercise. It is helpful to monitor blood glucose levels frequently after exercise. Delayed hypoglycemia often occurs during the night. If this occurs regularly, it can intensify fatigue in athletes. Waking up feeling very tired and groggy in the morning may indicate you have experienced a 'hypo' during the night. This is a sign that you need to increase blood glucose monitoring after similar exercise sessions in the future.
Alcohol inhibits the release of glucose from the liver and therefore increases the risk of hypoglycemia. Consuming excessive alcohol also impairs the ability to recognize the symptoms of hypoglycemia. Sensible use of alcohol should be discussed with your diabetes specialist. All athletes are encouraged to moderate alcohol intake after exercise and ensure recovery needs are taken care of first.
Little research is available directly on athletes with diabetes. However, it is possible that people with Type 1 diabetes have a reduced ability to store glycogen after exercise. This may be an issue when strenuous training sessions are held within a short period of time (less than 24 hours apart).
Practical Strategies for Managing Diabetes Before, During, and After Exercise...
Before training and competing
Hydration — Start workouts and competitions fully hydrated. Consume 400–600 ml of water or sports drink (not all sports drinks are carb free) 2–3 hours before exercise. It can help make up for any fluid deficits left over from prior workouts. Also, hydration status before exercise can be monitored by checking urine color. A light-yellow color is generally consistent with adequate hydration. If urine is darker, like the color of apple juice, that’s often a sign that more fluids are needed.
Pre-exercise eating — Eat a meal 2–4 hours before training or competing. It can help top off muscle and liver glycogen fuel stores.
The meal should be composed of familiar and well-tolerated carbohydrate foods and beverages.
Slow-to-digest fatty and high-fiber foods should be avoided in the pre-exercise meal.
Carbohydrate-rich foods include pasta, rice, bread, cereal, vegetables, fruit, and dairy products such as yogurt and milk.
For some athletes, the pre-exercise meal may need to be followed up with a small snack closer to exercise.
Check blood sugar before exercise — it’s important to ensure that your blood glucose concentration is at an appropriate level before starting exercise.
Exercising with a high blood glucose concentration — hyperglycemia — disrupts normal metabolic control and will elevate glucose levels even further.
Starting with a low blood glucose level should also be avoided.
Use the table below as a guide for what to do with your monitoring result. However, you should also discuss this with your physician or sports nutritionist, since the appropriate action can be more complicated depending on what activity you are planning.
Blood glucose control is often tighter if a consistent training routine is followed. It’s more difficult in situations when the start time of a competition is unknown or the length of an event varies. Knowing about and remaining vigilant to the development of symptoms of hypo- and hyperglycemia, and regular monitoring of blood sugar, are necessary in these situations. The same is true for elevated ketones in the bloodstream and the need for monitoring urine ketone levels
Blood Glucose Levels and Strength Training
Strength-oriented exercise (e.g. lifting weights or even sports like taekwondo) generally requires short, repetitive and intensive bursts of movement. This type of exercise can trigger a hormone response known as the 'fight or flight' or 'adrenalin' response that can temporarily raise blood glucose levels.
Currently, it is not known whether this temporary hyperglycemia from weight training has any long-term effect and management of this response is difficult and still controversial.
Decreasing carbohydrate intake to avoid the anticipated hyperglycemia might jeopardize performance during exercise and increase the risk of delayed hypoglycemia after exercise.
Increasing insulin dose after exercise to reduce blood glucose concentrations may increase the risk of delayed hypoglycemia once the 'adrenalin' response has worn off.
Regular blood glucose monitoring is important to be aware of how the body responds to strength exercise. Consult your diabetes specialist if you are concerned about your blood glucose response to weight training and seek guidance on the best way for you to respond.
Is carbohydrate loading safe for people with diabetes?
The Carbohydrate Loading fact sheet on the AIS Sports Nutrition website provides general information. Carbohydrate loading is dependent on insulin availability and therefore requires good diabetic control. It is necessary to adjust insulin administration to account for the increased carbohydrate intake and the effects of an exercise decrease. Regular blood glucose monitoring is essential when carbohydrate loading. Carbohydrate loading should not be attempted if blood glucose control is poor. Seek advice from your diabetes specialist and sports dietitian if you wish to use this method.
Using a training diary...
A training diary can be a very useful tool. You can also record the results of your blood glucose testing in your diary, so you can monitor both diabetes and non-diabetes-related factors at the same time. This information allows you to identify problem areas and to take steps to rectify them. Record the information even when things are going well; that way, if you are going through not-so-good times, you can look back on strategies that have worked for you earlier.

Fifteen facts you probably never knew about vitamin D and sunlight exposure!!!
G.Surya Thejaswi, M.Pharm
Clinical Research Associate
MV Hospital for Diabetes & Diabetic Research Centre
Vitamin D prevents osteoporosis, depression, prostate cancer, breast cancer, and even effects diabetes and obesity. Vitamin D is perhaps the single most underrated nutrient in the world of nutrition. That's probably because it's free; your body makes it when sunlight touches your skin.Vitamin D is produced by your skin in response to exposure to ultraviolet radiation from natural sunlight.
1. The healing rays of natural sunlight (that generate vitamin D in your skin) cannot penetrate glass. So you don't generate vitamin D when sitting in your car or home.
2. It is nearly impossible to get adequate amounts of vitamin D from your diet. Sunlight exposure is the only reliable way to generate vitamin D in your own body.
3. A person would have to drink ten tall glasses of vitamin D fortified milk each day just to get minimum levels of vitamin D into their diet.
4. The further you live from the equator, the longer exposure you need to the sun in order to generate vitamin D. Canada, the UK and most U.S. states are far from the equator.
5. People with dark skin pigmentation may need 20 - 30 times as much exposure to sunlight as fair-skinned people to generate the same amount of vitamin D. That's why prostate cancer is epidemic among black men- it's a simple, but widespread, sunlight deficiency.
6. Sufficient levels of vitamin D are crucial for calcium absorption in your intestines. Without sufficient vitamin D, your body cannot absorb calcium, rendering calcium supplements useless.
7. Chronic vitamin D deficiency cannot be reversed overnight: it takes months of vitamin D supplementation and sunlight exposure to rebuild the body's bones and nervous system.
8. Even weak sunscreens (SPF=8) block your body's ability to generate vitamin D by 95%. This is how sunscreen products actually cause disease by creating a critical vitamin deficiency in the body.
9. It is impossible to generate too much vitamin D in your body from sunlight exposure: your body will self-regulate and only generate what it needs.
10. If it hurts to press firmly on your sternum, you may be suffering from chronic vitamin D deficiency right now.
11. Vitamin D is "activated" in your body by your kidneys and liver before it can be used.
12. Having kidney disease or liver damage can greatly impair your body's ability to activate circulating vitamin D.
13. Even though vitamin D is one of the most powerful healing chemicals in your body, your body makes it absolutely free. No prescription required.
Top Ten Tips for Healthy Sun Exposure and Optimizing your Vitamin D Levels:
1. Have a healthy respect for the sun.
2. Always avoid sunburn.
3. Prepare your skin and build up tolerance gradually.
4. Get 15-30 minutes of unprotected sun exposure 2-4 times a week.
5. Get frequent, short exposures.
6. After your 15-30 minutes of sun-block free time in the sun, you must protect yourself.
7. Boost your “internal sunscreen” by anti-oxidants and beneficial fats.
8. Have your Vitamin D blood levels checked regularly.
9. Don’t rely on food alone for your Vitamin D needs.
10. Take Vitamin D3 supplements if necessary.
