What are proteins and how much do you need?



Proteins are large molecules that our cells need to function properly. They consist of amino acids. The structure and function of our bodies depend on proteins. The regulation of the body's cells, tissues, and organs cannot happen without them.

Muscles, skin, bones, and other parts of the human body contain significant amounts of protein, including enzymes, hormones, and antibodies.

Proteins also work as neurotransmitters. Hemoglobin, a carrier of oxygen in the blood, is a protein.

What are proteins?


Proteins are long chains of amino acids that form the basis of all life. They are like machines that make all living things, whether viruses, bacteria, butterflies, jellyfish, plants, or human function.

VITAMINS: The Micronutrients in Our Body !



The essential macronutrients are water, proteins, carbohydrates, fats, vitamins, and minerals.

In developed countries, vitamin deficiencies result mainly from poverty, food fads, drugs, or alcoholism. Vitamin toxicity (hypervitaminosis) usually results from taking megadoses of Vitamin A, D, B6, or niacin. In general, excess amounts of water-soluble vitamins are excreted via the Kidneys.


Vitamins may be Fat soluble (vitamins A, D, E, and K) or Water soluble (B vitamins and vitamin C). The B vitamins include biotin, Folate, niacin, pantothenic acid, riboflavin, thiamine, pyridoxine, and B12. After digestion and absorption, which circulatory system carries fat and fat-soluble vitamins?
“Vitamins are the essential nutrients that our body needs in small amounts. More specifically, an organic compound is defined as a vitamin when an organism requires it, but not synthesized by that organism in the required amounts (or at all). There are thirteen recognized vitamins.”
Vegans may develop vitamin B12 deficiency unless they consume yeast extracts or Asian style fermented foods. Strictly, vegetarian diets also tend to be low in calcium, iron, and zinc.

The Best Medicine Against Cholesterol And High Blood Pressure

Cholesterol is a waxy substance that comes from two sources: your body and food. Excess cholesterol can form plaque between layers of artery walls, making it harder for your heart to circulate blood.

Plaque can break open and cause blood clots. If a clot blocks an artery that feeds the brain, it causes a stroke. If it blocks an artery that feeds the heart, it causes a heart attack.

Heart disease, stroke and other cardiovascular diseases are among the leading cause of death and now kill more than 800,000 adults in the US each year. Two main reasons people have heart disease or stroke are high blood pressure and cholesterol.

How To Prevent and Treat Fatty Liver

I have a Fatty Liver- Now what?
Many of my clients have digestive issues and think it is to do with a food they are eating. Sometimes they opt for allergy testing, others get blood work or an ultrasound done to see if there are any serious problems.

More and more clients are been diagnosed with a fatty liver and ask me now what do I do?

What is a fatty liver?
A fatty liver is the result of excess fat in the liver. This fat builds up when a person’s diet exceeds the amount of fat their body can handle. Having a fatty liver can lead to fatty liver disease, which then leads to chronic illnesses. Many who are overweight, have belly fat, are insulin resistant, pre- diabetic and who crave sugars and starches are likely have a fatty liver. Yet many who are ultimately healthy and not overweight are finding they to, have a fatty liver.

H. Pylori: Know the Facts

Helicobacter pylori, commonly called H. pylori, is a type of bacteria that can infect the stomach and small bowel. It was discovered in 1982 by two Australian researchers who found that it causes peptic ulcer disease.

Peptic ulcers are open sores in the lining of the stomach or the upper part of the small intestine. Peptic ulcers are often called "ulcers" or "stomach ulcers."

For years, medical experts believed that peptic ulcers were caused by stress or certain foods. After the discovery of H. pylori, however, this belief was put to rest. A study in Digestive and Liver Disease suggests that 60 to nearly 100 percent of peptic ulcers are associated with H. pylori.


H. pylori bacteria attack the protective lining of the stomach, causing ulcer, that can be diagnosed
with an endoscopy.

Could Magnesium Regulate Blood Pressure?

A round one third of adults in the United States have high blood pressure, only half of whom have their high blood pressure under control. New research, published in the American Heart Association's journal Hypertension, identifies magnesium as a potential remedy.

With high blood pressure affecting around 70 million people in the U.S. and increasing the risk of two of the leading causes of death for Americans - heart disease and stroke - preventing or controlling blood pressure is an essential healthcare objective.

Labeled the "silent killer," due to often having no warning signs or symptoms, high blood pressure is a common and often dangerous condition.

A meta-analysis, funded by the Indiana University School of Medicine Strategic Research Initiative, details positive results that show an association between a daily intake of magnesium and a reduction in blood pressure.

Magnesium is already recognized as essential for over 300 biochemical reactions in the body.


A healthy diet rich in green leafy vegetables, legumes, nuts, seeds, and whole grains could lower
blood pressure.

Eating Walnuts May Help Prevent Colon Cancer

A team of researchers from UConn Health and The Jackson Laboratory for Genomic Medicine found that eating walnuts can reduce one's risk of getting colon cancer.

In the study, mice that were fed walnuts (totaling seven percent to 10.5 percent of their total calories) developed fewer instances of colon cancer.

Seven to 10.5 percent of daily total calories coming from walnuts is equivalent to a human eating about an ounce of walnuts every day.

Walnut consumption
"Our results show for the first time that walnut consumption may reduce colon tumor development," said Daniel W. Rosenberg of UConn Health, principal investigator on the study.


Could walnuts be the key to preventing colon cancer?

Is Okra Good for Diabetes?

According to a handful of recent studies, okra may reduce symptoms of diabetes - a group of diseases that includes type 1 diabetes, type 2 diabetes, and gestational diabetes.

Diabetes claimed the lives of 75,578 Americans in 2013, according to the United States Centers for Disease Control and Prevention (CDC). In 2014,8.5 percent of adults worldwide had the condition, the World Health Organization (WHO) report. By 2030, diabetes may be the seventh leading cause of death.

A number of factors increase a person's risk of developing diabetes, including a family history of the disease. Lifestyle factors also play a role, so doctors routinely recommend diet changes and increased exercise to reduce blood sugar levels.


Okra belongs to the same family of plants as cocoa and cotton.

What Do You Want to Know About High Cholesterol?

Cholesterol is a substance that your liver produces naturally. It’s vital for the formation of cell membranes, vitamin D, and certain hormones.

Cholesterol is a waxy, fat-like substance. It doesn’t dissolve in water and therefore can't travel through the blood by itself. Lipoproteins are other particles formed in the liver that help transport cholesterol through the bloodstream. There are several major forms of lipoproteins that are important to your health.

Neurotensin, A Hormone Found In The Digestive Tract, May Play Role In Obesity By Aiding In Fat Absorption From Food

A hormone predominantly found in our guts may help us absorb fat from our diets and could contribute to the development of obesity under certain circumstances, according to a new study published Wednesday in Nature.

The researchers, primarily hailing from the University of Kentucky, conducted a series of experiments on lab mice, fruit flies, and humans that examined how the hormone, called neurotensin (NT), functions in the gut. Mice deficient in NT proved less able to absorb fat from food and they appeared to be protected from conditions like obesity, fatty liver, and insulin resistance that are associated with a high-fat diet. On the other hand, fruit flies engineered to produce NT accumulated more fat in their bodies than normal.

Aside from seeing a similar fat absorption effect in human gut cells, the researchers also analyzed data from an earlier, long-running population study of middle-aged adults and found that obese and insulin-resistant individuals were more likely to have high levels of a precursor hormone, Pro-NT, in their blood. Those who weren’t obese but had the highest levels of Pro-NT were more than twice as likely to eventually develop obesity than people with the lowest levels of Pro-NT.


New research suggests that a hormone found in our gut may help us break down fats, like the kind in
butter, above, and possibly contribute to obesity

Know about gluten and its facts, foods and allergies.

Gluten is the general term for a protein found in wheat, barley, rye and triticale. All forms of wheat contain gluten, including durum, spelt and farro.

Wheat is commonly found in bread, baked goods, crackers, cereals and pasta. Soups may contain gluten, as well as sauces and salad dressings. Barley is often found in malt, food coloring, soups, malt vinegar and beer.

Unfortunately, a significant number people have an adverse reaction to gluten when they consume it, meaning that they must adhere to a gluten-free diet to remain healthy.

This Knowledge Center article provides further information on gluten, including why some people should avoid consuming it and which foods are known to contain gluten.
