10 Easy Tips to Eat Your Way to Lower Cholesterol

Do you have high cholesterol and need to lower it? That is no surprise considering how many people have high cholesterol these days. To help lower your cholesterol, here are 10 tips you can get started with today.

As with anything health related, diet and exercise are the two crucial components. What you eat is critical to lowering your cholesterol levels, so that is what is included here.

One thing you should know is the difference between LDL and HDL cholesterol. Simply think of HDL as "healthy" and LDL as "lousy." HDL can actually help carry cholesterol out of your blood vessels while LDL allows it to deposit inside your artery walls.

The good news is that you can change your cholesterol for the better. Here is how to do just that:

1. Have a nice sandwich on whole wheat bread or a pita with some lean turkey and lots of fresh veggies. Skip the hot dogs, bologna, and salami, and hold the Mayo. All of those are highly processed and filled with fat and cholesterol.

2. Fish, like salmon, is good. Look for wild red salmon varieties, which are very high in Omega-3 fatty acids (good fat.) Also, flax seed is a good source of Omega-3s.

3. Avoid Trans fats! Not only do they raise the lousy LDL cholesterol, they can also lower your HDL levels! Stay away from foods like margarine, shortening, and processed foods containing partially hydrogenated soybean oil.

4. Go ahead, go nuts! Look for walnuts mainly but also try almonds, macadamia nuts, cashews, and pecans. Nuts are high in fat, but it's the good kind. (Also, use natural peanut butter instead of the normal kind which contains unhealthy Trans fats.)

5. Limit desserts and try to eat only the healthier ones like angel food cake, graham crackers, Jell-O, and fat-free frozen yogurt.

6. Eat foods that are high in fiber. Examples include whole wheat bread, oatmeal, fruits, vegetables, beans, and some cereals. (Look for the boxes that say "may help lower cholesterol.")

7. Use the grill. If you're going to have steak or burgers, grill them at home and use lean meat. This practice avoids the grease, is fun, and the meat tastes great.

8. Find a new salad dressing. Most of them are full of Trans fats and cholesterol. Olive oil is good, and maybe add vinegar or lemon juice. Also, skip the bacon bits, croutons, and egg yolks.

9. Go overboard on fruits and vegetables. They contain no cholesterol and they have lots of nutrients like antioxidants.

Here are some examples: green peas, broccoli, cauliflower, apples, oranges, mangos, papaya, pineapple, tomato, garlic, onions, spinach, water chestnuts, bananas, apricots, blueberries, and kiwi.

10. Avoid fast food like french fries and anything else from the deep fryer. Those foods will raise your cholesterol like crazy, so stay away from the burger joints if you can.

11. Bonus tip: Use spices like pepper and oregano to add flavor to your dishes. They are a healthy alternative to other toppings like Mayo.

That was easy, wasn't it? Just make some of these changes and get plenty of exercise like walking, jogging, swimming, or playing basketball. You will have lower cholesterol in no time!

A Weighty Issue: Does Soda Promote Weight Gain?

As childhood obesity continues to increase, researchers are looking at a link between what kids drink and their expanding waistlines.

While experts stop short of laying the blame completely at the feet of soda makers, most acknowledge that people in general, and kids specifically, consume too many soft drinks.

In an effort to curb the problem, some school districts are removing soda machines from school campuses -; and, some say, for good reason. One 12-ounce can of soda has 150 calories; a 20-ounce can has 250 calories.

According to the Center for Science in the Public Interest, "Carbonated soft drinks are the single biggest source of calories in the American diet, providing about 7 percent of calories." Non-carbonated drinks (such as fruit juice and iced teas) push that figure to 9 percent.

One study of 548 sixth and seventh-graders in Boston showed that each 12-ounce can of soda consumed increased their risk for becoming overweight by 60 percent, according to an article in the Journal of Pediatrics.

Besides having a high-sugar content - which can contribute to weight gain and promote tooth decay - there is little nutritional value in a can of soda, just empty calories.

So what's a parent to do?

A diet rich in fruits, vegetables and whole grains should be the first line of defense. But because what they drink matters just as much as what they eat, one option may be to consider replacing soda with a health beverage like NuVim, which contains a variety of vitamins, minerals, calcium; low amounts of sugar; and no caffeine.

Tested and proven effective in 19 clinical studies for its muscle flexibility and immune-boosting properties, this beverage contains the antioxidant vitamins A, C and E, along with B-12, zinc, calcium and essential amino acids.

NuVim comes in a variety of fruit flavors and is located in the refrigerated juice section of your local supermarket.

All about Antioxidant

An antioxidant is a chemical that reduces the rate of particular oxidation reactions in a specific context, where oxidation reactions are chemical reactions that involve the transfer of electrons from a substance to an oxidising agent.

Antioxidants are particularly important in the context of organic chemistry and biology: all living cells contain complex systems of antioxidant chemicals and/or enzymes to prevent chemical damage to the cells' components by oxidation. The importance and complexity of antioxidants in biology is reflected in a medical literature of more than 142,000 scholarly articles.

A diet containing antioxidants from plants are required for good health since plants are an important source of organic antioxidant chemicals. Antioxidants are widely used as ingredients in dietary supplements that are used for health purposes such as preventing cancer and heart disease. However, while many studies have suggested benefits for antioxidant supplements, several large clinical trials have failed to clearly demonstrate a benefit for the formulations tested, and excess supplementation may be harmful.

Antioxidants are chemicals that reduce oxidative damage to cells and biochemicals. Researchers have found high correlation between oxidative damage and the occurrence of disease. For example, LDL oxidation is associated with cardiovascular disease. The process leading to atherogenesis, artherosclerosis, and cardiovascular disease is complex, involving multiple chemical pathways and networks, but the precursor is LDL oxidation by free radicals, resulting in inflammation and formation of plaques.

Research suggests that consumption of antioxidant-rich foods reduces damage to cells and biochemicals from free radicals. This may slow down, prevent, or even reverse certain diseases that result from cellular damage, and perhaps even slow down the natural aging process.

Since the discovery of vitamins, it has been recognized that antioxidants in the diet are essential for healthful lives. More recently, a large body of evidence has accumulated that suggests supplementation of the diet with various kinds of antioxidants can improve health and extend life.

Many nutraceutical and health food companies now sell forms of antioxidants as dietary supplement. These supplements may include specific antioxidant chemicals, like resveratrol (from grape seeds), combinations of antioxidants, like the "ACES" products that contain beta carotene (provitamin A), vitamin C, vitamin E and Selenium, or specialty herbs that are known to contain antioxidants such as green tea and jiaogulan.

All About Protein

Proteins are very important to our bodies. It isn't just for bodybuilders who use them to gain muscle mass. Those who are sick use them to rebuild damaged tissue and even in normal states, our body uses protein for many different tasks.

Proteins are made of amino acids that are folded together. There are essential amino acids - those that our body cannot make, and non essential amino acids - those that our body can make. Proteins that are made up of all the essential amino acids are said to be complete while those that lack in one or more essential amino acid are incomplete. Complete proteins come from sources such as meat, eggs, cheese, dairy and soy. Incomplete proteins come mainly from vegetable sources with the one exception being soy.

The ideal source should be complete proteins. For most people that isn't a problem. If you are worried about fat intake, try lean cuts of beef, chicken and turkey. For vegetarians whose main source comes from incomplete proteins, getting a variety of vegetables and whole grains throughout the day will ensure that all essential amino acids are consumed. Also, using soy protein (which is the only complete vegetable source of protein) is very beneficial.

All About Fats

With the low carbohydrate craze, many people have turned their attention to fats. They eat more of it and think its fine. Depending on what kind of fat you are consuming and how much of it you take in, fats can be beneficial or detrimental to your health.

There are three main types of fat. They are saturated, unsaturated and trans fats. Saturated fats come mainly from animal sources such as meat and dairy. At room temperature, saturated fats are solid. Unsaturated fats come mainly from plant sources such as olives and nuts and contain no cholesterol. They are liquid (oil) at room temperature. Unsaturated fats are broken down further in monounsaturated (one double bond) and polyunsaturated (more than one double bond).

You might be asking yourself what a fat is saturated or unsaturated with. A fat molecule (without getting into too much chemistry) is made up of carbon atoms that have hydrogen atoms attached to them.

In saturated fats, all carbon atoms have a single bond to another carbon atom and are also bonded to hydrogen atoms. In unsaturated fats, not all carbons are saturated with hydrogens so double bonds form between carbons. Depending on what carbon the double bond is formed determines the fat's properties.

Trans fat is man made fat. It is made by taking an unsaturated fat and putting hydrogen through it in a process called hydrogenation. Trans fat is very bad for your health. Whole saturated fat increases LDL (bad) cholesterol and very slightly increases HDL (good) cholesterol, trans fat increases LDL cholesterol and decreases HDL cholesterol.

All About Carbohydrates

Normally carbohydrates are found in all foods except meat products. Recently, some diets have recommended stripping out all carbohydrates from what you eat. Many companies have bought into this and among other things, have introduced low-carb breads. Limiting bad carbohydrates such as sugar from your diet is a positive step but going further and refusing to eat fruits and whole grains can potentially deprive you of cancer fighting foods.

Carbohydrates can be broken down into two main categories; simple and complex. Sodas, candy and even fruits contain simple sugars while whole grains, fruits and cereals contain complex carbs. The main difference between the two groups are their chemical structures. Simple sugars are made up of a few sugar molecules while complex carbs are made up of hundreds and even thousands of these molecules put together. In you body, the end product of both is glucose.

Another difference between the two is the time needed to digest. If you consume 100 calories of simple sugars, your body can digest it a lot faster than if you eat the same amount of calories that are made of complex carbs. This is because simple sugars are closer to the end product than complex carbs which need more time to digest. Therefore if you take the meal of simple sugars, you will be hungrier sooner than if you ate the meal made of complex carbs. Making a habit of drinking soda and eating candy can add up to a lot of calories at the end of the day.

Studies have shown that simple sugars contribute to obesity and diabetes, especially in children. It has also been shown that eating the good carbs can shield you from many types of cancers. So next time you pick up the magazine about the newest low carb claim, throw it away and grab an apple.

About Omega 3 Fish oils

Question: What’s all the fuss about Omega 3 fish oils? What do they do for my body?

Answer: Omega 3 fish oils are a substance that can be found in the bodies of fish. However, eating fresh fish is no longer recommended. The mercury levels that are prevalent in almost all fresh fish these days can be very detrimental to your health. However, companies have manufactured fish oil that is mercury free by processing the oils that naturally occur in the fish. Omega 3 is a type of fat that is essential for human health. Omega 3 contains two fatty acids that benefit the human body greatly, which are known as DHA and EPA.

These fatty acids have been linked to helping prevent heart disease, cancer, and many other diseases. DHA is also required by the human brain. Low levels of DHA in the brain have been linked to depression, schizophrenia, memory loss, and an increased chance of being stricken with Alzheimer’s disease. Therefore, the regular and repeated consumption of Omega 3 fish oils can greatly help affect the quality of your life for the better.

The American Heart Association recommends the use of fish oils to help your hearts performance as long as you keep your dosage under 3 grams per day, suggesting an amount roughly between 0.5 to 1.8 grams per day. Clinical trials conducted have shown that Omega 3 fish oils can reduce cardiovascular events including heart attacks, strokes, and even death.

Also, research has shown that fish oils can help decrease the risk of arrhythmias, decrease triglyceride levels, decrease the growth rate of atherosclerotic plaque, and even slightly lower blood pressure! With all these facts, there is no doubt that the regular and responsible use of Omega 3 fish oils from supplements can be of great benefit to your health.
