This project mainly concerns to provide an online facility to encourage people to have healthy diets, tips on losing weight and solutions for overweight persons.
The first step towards healthy eating is to “eat smart”. It's not just what you eat, but how you eat. Paying attention to what you eat and choosing foods that are both nourishing and enjoyable helps support an overall healthy diet.
To ensure that you get a well-balanced diet that provides the daily nutrients you need, it is recommended to focus your diet on the following basic food groups. The basics on carbohydrates, proteins, fats, fiber.
We all need a balance of carbohydrates, proteins, fats, vitamins to sustain a healthy body. But knowing the right amount to take is also important, so understanding dietary guidelines is the first step in developing your own healthy eating plan.
Carbohydrates
Carbohydrates – food composed of some combination of starches, sugar and fiber - provide the body with fuel it needs for physical activity by breaking down into glucose, a type of sugar our cells use as a universal energy source.
Proteins
Our bodies need protein to maintain our cells, tissues and organs. Getting the right amount of protein is a fine balance: eat too little and your body may start to break down its own tissues; eat too much and it can damage your kidneys.
Sources of Protein
Most people rely on red meat products for their main protein source, but red meats contain a lot of unhealthy fat. Aim for protein sources that contain the highest amounts of protein with the lowest amount of saturated fat.
Eating omega-3 fatty acid-rich fish can reduce the risk of heart disease. Good choices also include chicken, turkey, and eggs. Vegetarians and vegans can substitute vegetable protein for these sources, but may want to consider an omega-3 supplement.
Fats
Our bodies use fat to do everything from building cell membranes to performing key functions in the brain, eyes, and lungs, and use the different types of “good” fats (unsaturated, mono-saturated, poly-unsaturated, omega 3 and 6).
Healthy Fats
They are essential to us to provide the right amount of beneficial good fats in a balanced diet. Healthy Fats and Oils are important to support brain and body functions.
The “bad” fats - trans and saturated fats - increase the risk for certain diseases. Trans fats, or trans fatty acids, are the worst things of the nutrition world. Created by adding hydrogen to liquid vegetable oils to make them more solid, trans fats give foods a longer shelf life. While they might be beneficial to processed food manufacturers, trans fats are detrimental to you – they raise bad (LDL) and lower good (HDL) cholesterol, putting you at increased risk for heart disease.
Milk and other dairy products for calcium and vitamin D.
Dairy products provide a rich source of calcium, necessary for bone health. Most are fortified with vitamin D, which helps the small intestine absorb calcium.
How much water should we consume for a healthy diet?
Most experts suggest drinking at least eight glasses of water a day. However, you may need to drink more water if you are very active, pregnant or breastfeeding, live in a warmer climate, or have certain health problems. Heavy people may also need more water.
Healthy Tips and Strategies for a healthy diet
The following tips can help you ease your way into a healthier diet.
1. Read the labels – Always look at the first ingredient listed - seeing sugar, syrup, salt, or some other unhealthy ingredient high on the list probably means it isn’t the healthiest choice.
2. Keep a food diary – For one week, write down everything that you eat or drink every day. If possible keep track of serving sizes. At the end of the week, review your diary and decide where you need to make improvements.
3. Set goals – Your goal can also be as simple as ordering a salad rather than a less-than-healthy appetizer or side whenever you go out to eat.
4. Eat plenty of high-fiber foods—i.e. fruits, vegetables, beans, and whole grains. These are the "good" carbohydrates—nutritious, filling, and relatively low in calories.
5. Make sure to include green, orange, and yellow fruits and vegetables—such as broccoli, carrots, cantaloupe, and citrus fruits. The antioxidants and other nutrients in these foods may help protect against developing certain types of cancer and other diseases. Eat five or more servings a day.
6. Limit your intake of sugary foods, refined-grain products such as white bread, and salty snack foods. Sugar is the main additive, is added to a vast array of foods.
7. Cut down on animal fat. It’s rich in saturated fat, which boosts blood cholesterol levels and has other adverse health effects. Choose lean meats, skinless poultry, and nonfat or low-fat or nonfat dairy products.
8. Eat more fish and nuts, which contain healthy unsaturated fats. Substitute olive or canola oil for butter or stick margarine.
9. Keep your cholesterol intake below 300 milligrams per day. Cholesterol is found only in animal products, such as meats, poultry, dairy products, and egg yolks.
10. Eat a variety of foods. Don't try to fill your nutrient requirements by eating the same foods day in, day out. It is possible that not every essential nutrient has been identified, and so eating a wide assortment of foods helps to ensure that you will get all the necessary nutrients. In addition, this will limit your exposure to any pesticides or toxic substances that may be present in one particular food.
11. Maintain an adequate calcium intake. Calcium is essential for strong bones and teeth. Get calcium from low-fat sources, such as skim milk and low-fat yogurt. If you can't get the optimal amount from foods, take supplements.
12. Try to get your vitamins and minerals from foods, not from supplements. Supplements cannot substitute for a healthy diet, which supplies nutrients and other compounds besides vitamins and minerals. Foods also provide the "synergy" that many nutrients require to be efficiently used in the body.
Obesity and Its Consequences
Excess body weight poses one of the most serious public health challenges. Poor diet, a lack of physical activity and the resulting obesity and its associated illnesses are together responsible for as much ill health and premature death as tobacco smoking. Overweight affects between 30% and 80% of adults in the different countries and up to one third of children.
Social determinants of obesity such as poverty and area deprivation are also associated with mental disorders such as depression and schizophrenia. Mental health problems are also risk factors for obesity in their own right, and there are strong associations between some of these disorders, such as depression and schizophrenia and obesity. A contributing factor is that some of the medication prescribed for mental health problems can cause weight gain.
Preventing obesity is thus an urgent public health goal that should be dealt with through innovative environmental approaches, very much like clean water supplies, sewerage treatment facilities and food inspection services were introduced in the 18th and 19th centuries and controls have recently been established on air pollution, drink–driving, seat belt use and smoking in public places.
