Food affects your brain power by affecting the production of neurotransmitters in your brain. By supplying amino acids, which are used as precursors to manufacture neurotransmitters, and by affecting the entry of the amino acids into brain, foods can have a significant impact on your brain activity. High-carbohydrate foods in general tend to subdue brain activity. Protein foods, on the other hand, can counteract carbohydrate food induced sluggishness. In addition, foods and herbs can have effects on brain activity by affecting blood circulation – the supply line of oxygen, nutrient, and hormone to the brain.

Nutritional Information. Ten seedless grapes (50g) provide 35 calories, 0.3 g protein, 8.9 g carbohydrate, 1.0 g fiber, 105 mg potassium, 5.4 mg vitamin C, 0.05 mg thiamin, 0.03 mg riboflavin, and 0.15 mg niacin.

Pharmacological Activity. Grape is a rich storehouse of antioxidant and anticancer compounds, including flavonoids (anthocyanin), quercetin, and resveratol (red grape skin). Grapes can inhibit blood-platelet clumping and consequently blood clot formation, and boost good type HDL cholesterol. Red grapes are antibacterial and antiviral. It has strong activity against cancers.

Eating Tips. Choose red or black colored grape instead of white or green one and eat with grape skin on to get the most health benefits.

Another reason why hot dogs are unhealthy may be due to the overall diet of a typical hot dog eater. People who eat high fat diets including red and processed meats are more likely to be overweight or obese, plus that hot dog may be taking the place of a much more nutritious fruit or vegetable. Hot dogs are also prone to carry the bacteria called listeria that causes foodborne illness.

Hot dogs, like all processed meats, should be eaten only rarely. While the occasional hot dog at a baseball game may not ruin your health, frequent consumption of hot dogs and other processed meats cannot be part of a healthy diet.

It is important to be prepared if you are going to eat good foods at home and not run out for fast food when you don’t feel like cooking. Unfortunately, grocery shopping can be very tedious. Set aside enough time to do your shopping for a few days worth of healthy food and ingredients. Make a list and stick to it. Don’t go shopping when you are hungry, and once you are at the store, stay away from the junk and the processed food aisles. Buy lots of fresh produce and choose lean meats and fish. Stay away from processed meats, fake cheese products, processed boxed and canned meals and avoid the snack aisle. Better yet, shop for organic products whenever possible. If you have no choice but to shop infrequently, choose frozen fruits and vegetables over canned, as they may retain more of their nutrients and don’t have the extra sodium.

If you are an emotional eater, keep the junk food like potato chips, tortilla chips, ice cream, and candy out of the house. Keep healthy snacks like fruits, crunchy vegetables with dips, or nuts handy. If you absolutely feel the need for a treat, then purchase a small piece of high quality chocolate or your favorite treat and enjoy it, just don’t buy any to bring home.

The same tips are helpful for those who enjoy TV snacking at home. If you don’t want to give up nibbling while watching your shows, keep low calorie foods close by, because it is very easy to eat too much when you are entranced by your favorite drama, football game or cooking show. Eat crisp raw vegetables with your dip instead of greasy chips.

The sight of certain foods can trigger a desire for the foods you are trying to avoid. Keeping snack stashes of high fat cookies or candy around may only increase the desire for such foods, making it difficult to resist snacking on them. Removing the temptations allows for healthy snacking while trying to lose weight. Maintain a variety of low-fat, healthy snack foods that can be eaten when the urge to snack hits. Also, planning for snacks and preparing them ahead of time may reduce the temptation to snack on high-calorie choices.

Snack time can also be more enjoyable if you are doing nothing while snacking but concentrating on the enjoyment of eating. Know the times when you are most likely to snack. Add a healthy snack food to your daily food plan to correspond with this time. Planned snacking allows you to adhere to your plan and avoid empty calorie snacking or overeating. Also, by not skipping meals, the likelihood of snacking on high-calorie foods will be reduced.

Smoking. Perhaps the most damaging lifestyle choice you can make is to smoke cigarettes. Smoking is the most preventable cause of illness and death in the United States.

Alcohol abuse. The most popular and accepted drug in America is alcohol. Its abuse can affect almost every system in the body. As a result, heavy drinkers often begin a gradual downward cycle, in which their bodies begin to degenerate slowly.

Risky sexual behavior. It’s gotten enough publicity that you’re probably aware of it, but it never hurts to restate the obvious: Having unprotected sex with an individual who carries a sexually transmitted infection or disease (such as hepatitis B or HIV) can be fatal.

Your activity level. Regular exercise confers many health benefits:

• Building lean body mass (which helps prevent obesity)
• Preserving bone density (which helps stave off osteoporosis)
• Improving the ratio of “bad” low-density lipoprotein cholesterol (LDL) to “good” high-density lipoprotein cholesterol (HDL) in the blood (which can help prevent heart disease)
• Reducing blood pressure
• Reducing resting heart rate
• Increasing energy and vigor
• Improving sleep
• Alleviating mild stress or depression

How much exercise do you need to stay healthy? In general, you should engage in at least 30 minutes of a moderately intense physical activity, such as a brisk walk, on most days of the week. To help manage weight and prevent gradual, unhealthy weight gain in adulthood, the Dietary Guidelines for Americans 2005 recommends 60 minutes of moderately to vigorously intense physical activity while not exceeding your caloric intake needs.

Your diet. Once you learn which foods are good for you, you need to look at your eating habits. If the foods you eat are not healthy, you might want to work within your habits and current lifestyle conditions, since they are usually tough to change. Consider these questions, then read on for tips to help you add healthy foods:

• Do you eat because you are bored, sad, or happy?
• Do you snack in front of the TV without even giving it much thought?
• Are most of your meals eaten at home or in restaurants?
• How often do you grocery shop?
• Do you skip breakfast or lunch, then overeat later in the day?
• How big are the portions you consume?
• Do you crave sweets?
• Are there foods you won’t give up?

 The Dietary Guidelines for Americans 2005 offer the following recommendations:

• Consume a variety of nutrient-dense foods and beverages within and among the basic food groups while choosing foods that limit the intake of saturated and trans fats, cholesterol, added sugars, salt, and alcohol.
• Find your balance between the calories you get from foods and beverages and the calories you expend each day. Meet recommended intakes within energy needs by adopting a balanced eating plan, such as a custom one for you from MyPyramid.gov — Steps to a Healthier You or the DASH Eating Plan. For more information about eating plans, visit www.mypyramid.gov.
• Eat a variety of fruits and vegetables each day. Select from all five vegetable subgroups (dark green, orange, legumes, starchy vegetables, and other vegetables) several times a week.
• Eat three or more ounce-equivalents of whole-grain products per day.
• When selecting and preparing meat, poultry, and dry beans, make choices that are lean, low fat, or fat free.
• Consume about three cups of fat-free or low-fat milk or equivalent milk products per day.
• Keep total fat intake between 20 and 35 percent of calories, with most fats coming from sources of polyunsaturated and monounsaturated fatty acids, such as fish, nuts, and vegetable oils.
• Moderate your intake of salt, sugar, and processed foods.

A diet that meets these requirements can help prevent cancer, gastrointestinal illnesses, and a host of other health problems. Conversely, a high-fat, low-fiber, high-sugar diet can set you up for unnecessary health problems down the road.

Heart disease and stroke are the leading causes of death and disability for people in the U.S. Overweight people are more likely to have high blood pressure, a major risk factor for heart disease and stroke, than people who are not overweight. Very high blood levels of cholesterol can also lead to heart disease and often are linked to being overweight. Being overweight also contributes to angina (chest pain caused by decreased oxygen to the heart) and sudden death from heart disease or stroke without any signs or symptoms. The good news is that losing a small amount of weight can reduce your chances of developing heart disease or a stroke. Reducing your weight by 10% can decrease your chance of developing heart disease.

How Is Obesity and Cancer Linked?

Several types of cancer are associated with being overweight. In women, these include cancer of the uterus, gallbladder, cervix, ovary, breast, and colon. Overweight men are at higher risk for developing colorectal cancer and prostate cancer. For some types of cancer, such as colon or breast.

How Is Obesity Related to Gallbladder Disease?

Gallbladder disease and gallstones are more common if you are overweight. Your risk of disease increases as your weight increases. It is not clear how being overweight may cause gallbladder disease. Ironically, weight loss itself, particularly rapid weight loss or loss of a large amount of weight, can actually increase your chances of developing gallstones or cause silent gall stones to become symptomatic. Modest, slow weight loss of about 1 to 2 pounds a week is less likely to cause gallstones.

How Does Obesity Cause Osteoarthritis?

Osteoarthritis is a common joint condition that most often affects the knee, hip, and lower back joints. Carrying extra pounds places extra pressure on these joints and wear away the cartilage (tissue that cushions the joints) that normally protects them. Weight loss can decrease stress on the knees, hips, and lower back and may improve the symptoms of osteoarthritis.

How Is Obesity Linked to Gout?

Gout is a disease that affects the joints that is caused by high levels of a substance called uric acid in the blood. The large amount of uric acid can form into solid or crystal-like masses that deposit in the joints. Gout is more common in overweight people and the risk of developing the disorder increases with higher body weights. Over the short term, certain dietary changes may lead to an attack of gout in people who have high levels of uric acid or who have had gout before. If you have a history of gout, check with your doctor before trying to lose weight.

How Is Obesity Linked to Sleep Apnea?

Sleep apnea is a serious breathing condition that is associated with being overweight. Sleep apnea can cause a person to snore heavily and to stop breathing for short periods during sleep. Sleep apnea may cause daytime sleepiness and even heart failure. The risk for sleep apnea increases as body weight increases. Weight loss usually improves sleep apnea.

1. Keep portion sizes small.

If the fast-food restaurant offers several sandwich sizes, pick the smallest or order half a sandwich, if available. By pass hamburgers with two or three beef patties, which can pack more than 1,000 calories and 70 grams of fat. Instead, choose a regular- or children’s-sized hamburger, which has about 250 to 300 calories. Also, skip the large serving of french fries or onion rings and ask for a small serving instead. This switch alone saves 200 to 300 calories. Or better yet, select a lower calorie option.

2. Choose a healthier side dish.

Take advantage of healthy side dishes offered at many fast-food restaurants. For example, instead of french fries choose a side salad with low-fat dressing or a baked potato. Or add a fruit bowl or a fruit and yogurt option to your meal. Other healthy choices include apple or orange slices, corn on the cob, steamed rice, or baked potato chips.

3. Go for the greens.

Choose a large entree salad with grilled chicken, shrimp or garden vegetables with fat-free or low-fat dressing on the side, rather than regular salad dressing, which can have 100 to 200 calories per packet. Watch out for high-calorie salads, such as those with deep-fried shells or those topped with breaded chicken or other fried toppings. Also skip salad extras, such as cheese, bacon bits, croutons and fried chips, which quickly increase your calorie count.

4. Opt for grilled items.

Fried and breaded foods, such as crispy chicken sandwiches and breaded fish fillets, are high in fat and calories. Select grilled or roasted lean meats.

To successfully lose weight, you’ve got to get in touch with the powerful forces that shape you’re eating habits? How supposed to suppose and feel about food and why you eat when you’re not hungry.

Here are four steps that can help you:

Step 1: Know your habits

To become aware of your eating habits, keep track of situations in which you find yourself craving unhealthy foods. Write them down in a notebook or on your weekly menus. Keep a list of what, when and why you eat for a few days. See if any relationships or patterns emerge. Ask yourself if you tend to eat when you’re bored, angry, tired, anxious, stressed, depressed or socially pressured. If you do, try these tips: Before eating anything, ask yourself if you’re really hungry. If the answer is no, consider having a glass of water. You may find that you’re just thirsty. Learn to refuse gracefully when people offer food that doesn’t fit into your menu plan such as treats at coffee breaks. Do something to distract yourself from your desire to eat — call a friend or run an errand. Direct emotional energy from stress or anger outward. Think about taking a walk, sorting through files, or cleaning out a cluttered drawer or closet. The urge to eat will pass. If you find that you absolutely can’t find an alternative strategy, don’t try to restrain yourself too much — that may lead to bingeing. In that case, eat some vegetables or a piece of fruit. You won’t have to feel guilty, and it may satisfy your craving.

Step 2:  Change gradually

When you’ve identified an eating habit that you’d like to change, remember that gradual changes work best. Consider this example. Marty works as a customer service manager for a retail department store. Her job is often stressful. She prides herself on meeting the needs of customers and sometimes finds herself juggling the needs of customers with the needs of management. When she feels overwhelmed by stress, she walks to the vending machine for a high-fat, high-calorie snack. Marty recognized that this was one eating habit preventing her from reaching a healthy weight. She decided to start dealing with on-the-job stress by taking a brisk, 10-minute walk at break time and by eating fruit for snacks. Like Marty, you, too, can prevent thoughts and feelings about food from standing in the way of your weight-loss program. Choose one area at a time and be specific about how you’re going to change. When you feel you’ve successfully changed one eating habit, work on another.

Step 3:  Plan ahead

Your old eating habits may be so ingrained that you’re not aware of them. Mentally rehearsing healthier habits can help. Imagine this: You’re at a graduation party. The buffet table is packed with all of your favorite treats. Now imagine this: You take a small portion of a few items from the buffet table, leaving space between them on your plate, or you take only fresh fruits and vegetables. Mentally rehearse this plan until you’re more likely to remember it — and do it — the next time you need it most.

Step 4:  Think positively

Don’t dwell on what you’re giving up to reach a healthy weight. Concentrate instead on what you’re gaining. Instead of thinking, “I really miss eating a doughnut at breakfast”, tell yourself, “I feel a lot better when I eat oatmeal and fresh fruit in the morning”. Believe it or not, the process of making changes to your eating habits can be enjoyable and the health benefits will soon become evident.
