Until the 1800s, tomatoes were considered toxic, but since then tomatoes have been a staple of many people's diet, and rightfully so , whether you consider it a vegetable or a fruit, it is very beneficial.

Besides containing 40 percent of your daily value of vitamin C, it also contains 15 percent of your daily value of vitamin A, 8 percent of your daily value of potassium, and 7 percent of your recommended dietary allowance of iron for women and 10 percent for men. In addition as a source of fiber, one medium tomato equals one slice of whole wheat bread with only 35 calories.

According to Homecooking.about.com, Lycopene, a dietary carotenoid found in high concentrations in tomatoes as well as processed tomato products, including ketchup and canned tomato products, is what gives tomatoes their red pigment. It is an antioxidant which purportedly fights the free radicals that can interfere with normal cell growth and activity. These free radicals can potentially lead to cancer, heart disease and premature aging.

A recent study has also shown that men who eat at least 10 servings of tomatoes a week can reduce their risk of developing prostate cancer by a whopping 45 percent.

The tomato is native to western South America and Central America. In 1519, Cortez discovered tomatoes growing in Montezuma's gardens and brought seeds back to Europe where they were planted as ornamental curiosities, but not eaten. A member of the deadly nightshade family, tomatoes were erroneously thought to be poisonous (although the leaves are poisonous) by Europeans who were suspicious of their bright, shiny fruit.

The French referred to the tomato as pommes d'amour, or love apples, as they thought them to have stimulating aphrodisiacal properties. Centuries later in 1897, soup mogul Joseph Campbell came out with condensed tomato soup, a move that set the company on the road to wealth as well as further endearing the tomato to the general public.

There are thousands of varieties of tomatoes in an array of shapes, colors and sizes. The most common shapes are round (Beefsteak and globe), pear-shaped (Roma) and the tiny cherry-sized (Cherry and Grape). Yellow varieties tend to be less acidic and thus less flavorful than their red counterparts. In the United States today, tomatoes are second in consumption only to potatoes.

When choosing the perfect tomato, use your nose. Smell the blossom (not the stem) end. The most flavorful ones will have a rich tomato aroma. Also be sure to choose one with a brilliant shade of red, as those tomatoes contain more betacarotene and lycopene giving you the most vitamins and minerals. Store fresh ripe tomatoes in a cool dark place, making sure it's stem-side down and use within a few days.

Foods that Boost Metabolism and Help Lose Weight

It may be true that an apple a day keeps the doctor away, but there are plenty of foods out there that are beneficial to you in more ways than one : including speeding up your metabolism.

According to MSNBC, metabolism is the process by which your body converts calories from food into energy. It is the body's engine that burns calories and regulates your caloric needs. The foods you eat play a major role in the way your body metabolizes fat. Some foods contain certain ingredients that help to burn calories more quickly, while also giving you other vital fuels that you need to increase energy levels, and prevent diseases later in life. There are also certain foods that require more calories to digest than the food actually contains, which can essentially speed up your metabolism.

Below are a few food suggestions provided by Ehow.com that can boost metabolism and encourage weight loss.

Spicy Foods- An interesting and effective way to boost your metabolism is to eat spicy foods. Spicy foods and spices, such as chili peppers and jalapeno peppers, contain the chemical capsaicin, which is what gives these foods their heat. Capsaicin increases and quickens adrenaline production in the body, which speeds up your basal metabolic rate, or BMR. Try eating spicy salsa, which gives you a lot of flavor without a lot of calories.

Carbs & Protein- Eating snacks that contain healthy carbohydrates and proteins will help boost energy and fill you up, so you can avoid overeating during meals. Eating these types of snacks in small portions will keep your metabolism going throughout the day, burning fat and increasing energy. Try snacking on peanut butter with a sliced banana, and apples dipped in peanut butter or paired with a few slices of cheddar cheese.

Green Tea- Green tea contains large amounts of the powerful antioxidant, epigallocatechin gallate, or EGCG. The oxidation process that occurs in green tea helps break down fat more quickly, while also helping to prevent cancer and heart disease. EGCG also promotes faster workings in the brain and nervous system, so the body burns more calories. If you don't like to drink green tea, they also sell caplets in health food stores.

B Vitamins- B vitamins have major benefits for many parts of the body: the central nervous system, metabolism and the production of energy. A vitamin B deficiency will cause your metabolism to slow down, your mood to become depressed and your body to feel tired and sluggish. B6, B12, thiamine, folate and niacin play major roles in the healthy function of your body. Snack on foods such as spinach, broccoli and asparagus; navy, soy and black beans; and melon, fish, poultry and eggs. In order to work these into your day, snack on cut-up honeydew or cantaloupe, a hard-boiled egg, a few pieces of sushi, or tortilla chips and a mixed bean dip.

Magnesium- Magnesium is a mineral that plays a key role in more than 300 chemical reactions in your body and contributes greatly to the synthesis of protein and metabolism. It also assists in proper nerve, heart and muscle function. To increase your levels of metabolism, eat green vegetables, such as spinach and broccoli; soybeans such as edamame; nuts, such as almonds, cashews and peanuts; and whole grain cereals, including oatmeal.

Summer Salads: Keep your Lettuce Fresher for Longer!

Now that summer is in full bloom, families will be turning to salads as their meal of choice when the temperature gets too hot to cook. But oftentimes, as soon as you go to reach for your favorite green leafy vegetable you realize that it has gone bad too soon.

Use these helpful tips to keep your lettuce fresher for a longer period of time and you'll be enjoying your salads all summer long:

First of all, it's important to purchase the freshest lettuce that you can to ensure that it lasts as long possible. Look for crisp leaves that are free of browning edges and rust spots. Check out your local farmer's market to browse the freshest fruits and vegetables around.

According to Stellaskitchen.com if you buy iceberg lettuce wrap it in a moist paper towel as soon as you get home and place it in a plastic bag before storing it in the refrigerator.

In regards to leafy lettuce greens like romaine, red leaf or green leaf lettuce, you can follow the same process. However, it is better to remove leafy greens from their plastic bag and pat the leaves dry with a paper towel before storing them if they are wet from the produce sprayer at the store. Squeeze the water out from the paper towel and wrap the lettuce up. Place the wrapped head of lettuce back in the bag and in the produce drawer.

Utilize containers that have special holes for specific vegetables (Tupperware's Fridgesmart is a great one for lettuce!)

Utilize air-tight plastic bags to store your lettuce in instead of the plastic bags you purchase the head in at the store.

Try to avoid bagged lettuce as it has already been preserved and is well on its way to spoiling.

Avoid metal pans to store your lettuce; this also speeds up the spoiling process.

Utilize your refrigerator's crisper as it truly does help to keep vegetables, like lettuce, crisper and therefore fresher.

Make sure to store your lettuce in your produce drawer with plenty of breathing room. Leaves can be easily bruised if you have lots of other veggies crammed in with the lettuce.

Here's another tip from Stellaskitchen.com regarding storing leftover salad- lay a damp paper towel over the top of the salad and cover the bowl with plastic wrap or a tight fitting lid.

By following these simple tips you'll be able to enjoy fresh, light summer salads all season long without having to worry about your leafy greens being soggy or brown.

Eat Your Fruits and Veggies to Lower Your Blood Pressure

According to a recent study done by the American Heart Association, one in three adults suffer from hypertension or high blood pressure. While many people are prescribed medication to help reduce their blood pressure, nutritionalists say that by simply eating your fruits and vegetables you can help reduce your blood pressure naturally.

According to Fruitsvegetablesthatlowerbloodpressure.blogspot.com, a diet high in vegetables not only helps to regulate blood pressure, but also lowers high blood pressure. Daily four to five servings of raw, leafy and cooked vegetables is essential to maintain normal blood pressure.

bitter melon carrots tomatoes broccoli cauliflower cabbage spinach lettuce kale

In addition to vegetables, incorporating fresh fruits into your diet will also help lower blood pressure. Fruits have many essential nutrients, vitamins and antioxidants. A daily serving of four to five different fruits is recommended by the National Institutes of Health (NIH), to maintain a healthy diet. Fruits are so versatile in taste and flavor, that they can be easily consumed in forms of salads, soups, juices, or even eaten in its natural raw state. Some fruits that help lower blood pressure include:

prunes watermelon bananas grapefruits lemons limes oranges tangerines

While all fruits and vegetables are good for you, the above contain the appropriate amounts of the right vitamins and nutrients that when added to your regular diet will equal out to a heart-supportive diet.

By simply making some small changes to your every day eating and making sure to get the appropriate number of foods and vegetables in your daily diet, you will see your blood pressure numbers gradually decrease.

Straight From the HeadlinesEating Junk Food An Addiction?

According to MSNBC, a recent study published in the journal “Nature Neuroscience”, states that a high-calorie diet, including junk food, may be as addictive as drugs like nicotine or cocaine, and could cause compulsive eating and obesity.

The study, conducted on rats, shows that overconsumption of high-calorie foods can trigger addiction-like responses in the brain, thereby turning the rats into compulsive eaters. Decreased levels of a specific dopamine receptor : a brain chemical that allows a feeling of reward : have been found in these overweight rats, as they are found in humans with drug addictions.

For the study researchers with The Scripps Research Institute in Florida headed to the grocery store and bought all of the stuff that people really like but really shouldn't eat very often, items such as Ding-Dongs, cheesecake, bacon, and sausage. They also bought healthy foods and devised a diet plan for three groups of rats.

One group of rats ate a balanced healthy diet. Another group received healthy food, but had access to high-calorie food for one hour a day. Rats in the third group were fed healthy meals and given unlimited access to high-calorie foods. The rats in the third group developed a preference for the high-calorie food, munched on it all day and quickly became obese.

All of the rats in the experiment were also trained to expect a minor shock when exposed to a light. But when the rats that had unlimited access to high-calorie food were shown the light, they did not respond to the potential danger. Instead, they just continued eating their snacks.

"What we're seeing in our animals is very similar to what you'd see in humans who overindulge,” researcher, Paul Kenny says. "It seemed that it was okay, from what we could tell, to enjoy snack foods, but if you repeatedly overindulge, that's where the problem comes in."

The research was conducted in conjunction with the announcement that obesity-related diseases cost the U.S. and estimated $150 billion each year and an estimated two-thirds of American adults and one-third of children are obese or overweight.
