Bread Shelf Confusion

Should I pick brown or white bread?

Most of us face this confusion everyday at bread shelf. Health concious fellows may pick the brown one as natural brown or dark brown colour relates to the presence of whole grain; which is dense in nutrients, antioxidants and phytochemicals.

This colour impression is missleading. There is a diffrence between brown and bran or whole grain bread. Brown colour bread may contain caramalized suagr or some colouring agent giving characterstic colour of whole wheat bread. 

Whole grain bread is made up of whole wheat flour having grem, bran and starchy endosperm. Have a look at structure of whole grain.

For white bread production refined flour is used. The refining process sift out nutrient rich bran and germ, leaving the starchy endosperm. White bread lacks nutrients of bran and germs like Fiber, vitamin E and B, magnesium, manganese, iron, phosphorous, potassium and zinc. Also, white bread and brown colour bread contains large proportion of high glycemic index carbohydrates. 

So next time when you are facing the bread shelf, read the ingredients list at the label to make the right choice. 

Fat for Life

No Fat, Low Fat, Fat Free and like claims are the center of attraction for today’s health oriented community. There is a vision that fat is not good for health. It is the culprit behind increased rate of Obesity and Coronary Heart Diseases. While the truth is fat plays an important role to maintain regular body functions. Fat is the structural component of the cell, our body needs it for cell repairing and growth. Too low fat diet disturbs the absorption of fat soluble vitamins and antioxidants. Cutting fat too much can lead to constant hunger.  Fat makes an insulating layer beneath the skin to maintain body temperature. It also surrounds and protects our delicates organs. Fat servers many physical, chemical and nutritional functions in the food. Fat improves the flavor, provides creamy texture and glossy look to the food.  To maintain acceptable taste profile in fat free products high quantity of refined carbohydrates and sugar is being used which ultimately leads to obesity.

Instead of being fat phobic, one should monitor the quality and quantity of fat. Fat alone don’t cause any disorder in our body. It is our life style practices such as physical activity, smoking and uncontrolled consumption of fatty foods that leads to excessive fat accumulation.

For lifelong healthy heart always prefer liquid fat over fat that is solid at room temperature. Monounsaturated fatty acids (MUFA) & polyunsaturated fatty acids (PUFA) keep heart healthy; they reduce serum cholesterol. Add no or less shortenings and hydrogenated fat in your plate. By the process of hydrogenation liquid fat is converted into solid fat at room temperature, during this process t here are chances of formation of Trans Fatty Acids. Avoiding fat completely is not the solution for obesity; it may cause other health problems in the long run. Understanding the difference between good and bad fat is the wise decision.

Health Benefits Of Fiber

Statistical data shows that cardiovascular diseases are the most prevalent cause of death worldwide. Dietary patterns and life style practices such as smoking, physical activity significantly affect cardiovascular heath. Epidemiological studies associate high dietary fiber intake with lower prevalence rate of coronary heart diseases, stroke and hypertension. Studies suggest high fiber consumption reduces major risk factors such as diabetes, obesity and dyslipidemeia.

Many cohort studies stated that high fiber consumption,specifically whole grains are associated with a significantly lower CVD risks. While cereal fibers are found to have very similar effects of whole grains. 26% reduction in stroke prevalence is allied with higher whole grain intake. In French and Chinese studies, high fiber consumption was linked with lower prevalence of hypertension, lower total serum cholesterol and triglyceride value than were lower intake. Chinese study also associated lower BMI with high fiber consumption. Persons with high fiber consumption levels have a 29% lower risk of CHD. Increased fiber intake modestly lower the blood pressure of normal people and also reduces systolic & diastolic blood pressure for hypertensive individuals by -6mm of Hg and -4 mm of Hg respectively.

Individuals with the highest level of dietary fiber consumption have 29% reduced risk for developing diabetes as compared to those with lowest intake. Randomized controlled clinical trials illustrated that moderate increase in dietary fiber intake are linked with improved fasting glycemia and insulinemia and increased insulin sensitivity for non diabetics. Randomized controlled clinical trials for diabetic individuals also suggest moderate increase in fiber utilization improves glycemic control.

 High fiber foods or supplements are likely to improve heart health, blood pressure, serum lipoproteins and also assist weight management. 

Worriers Against Cancer -- Fiber

Very few specific foods or drinks have been shown to significantly increase or reduce the risk of cancer. EPIC studies have found that eating foods high in fiber can reduce the risk of bowel cancer.  Some other large studies also support these findings. But few found that fiber does not affect bowel cancer risk, these studies don’t represent large populations.

Fiber could protect against colorectal cancer in different ways like

• It triggers the production of helpful chemicals. Bacteria in the bowel interact with fiber to produce several chemicals including butyrate.
• Soluble fibers increases the frequency of bowel movements, hence reducing the residence time of harmful chemicals in the body.
• Bioactive compounds in fiber sources also play important role in cancer prevention.

Nuts For Healthy Heart

WHAT ARE NUTS?

Nuts are botanically a type of single-seeded fruit in which the pericarp enclosing the seed is a hard woody shell. In common usage the term is used loosely for any hard, oil rich kernel. Of those commonly eaten, only hazel, filbert and chestnut are strictly nuts. Walnuts, pecans, almonds and coconuts are really drupes. Brazil nuts, pistachios, macadamias, and cashews are really seeds with a hard shell derived from the testa rather than the pericarp.[i]

According to the Spanish Food Code, nuts are those fruits the edible part of which has in its composition less than 50% of water. The products of certain trees are called nuts (tree nuts): almonds, hazelnuts, macadamia nuts, walnuts, cashew nuts, pine nuts and pistachios. In this group are also included peanuts and sunflower seeds.[ii]

WHY NUTS ARE SUGGESTED FOR CVDs PATIENTS?

On the basis of Epidemiological evidences, Nutritional, in -vitro studies and clinical trials nuts are considered as cardioprotectant functional food.

EPIDEMIOLOGICAL EVIDENCES

Some of the epidemiological studies are:

·         The Adventis health study

·         The Iowa women’s health study

·         The Nurses’ health study

·         All cause mortality and nut consumption

·         Secondary CHD prevention[iii]

 The epidemiologic studies have reported various endpoints, including fatal CHD, total CHD death, total CHD, and nonfatal myocardial infarct. In conclusion, the results of all the epidemiological studies confirm the cardiovascular protection of nuts. This protection is extended both to men and women of different races and ages, including postmenopausal. In addition, the protection, also, has been described in individuals with normal and with high blood pressure. At the same time, the consumption of nuts is associated with a low mortality rate and an increase in life expectancy without total cardiovascular disease total, which means living for a longer time free of this type of illnesses.

CARDIOPROTECTIVE NUTRIENTS AND DIETARY FACTORS IN NUTS

Nuts contain a combination of at least 28 different essential nutrients. Nuts are an excellent source of polyunsaturated and monounsaturated fats – the good fats – which can help manage blood cholesterol. A recent meta analysis found that eating on average 67g of nuts per day reduced total cholesterol by 5%, LDL (bad) cholesterol by 7% and triglycerides by 10%. In addition to being a rich source of several essential vitamins and minerals, mono- and polyunsaturated fatty acids, and fiber, most tree nuts provide an array of phytochemicals that may contribute to the health benefits attributed to this whole food. Although many of these constituents remain to be fully identified and characterized, broad classes include the carotenoids, hydrolyzable tannins, lignans, naphthoquinones, phenolic acids, phytosterols, polyphenols, and tocopherols. These phytochemicals have been shown to possess a range of bioactivity, including antioxidant, antiproliferative, anti-inflammatory, antiviral, and hypocholesterolemic properties. 

Studies have shown that those who eat a handful (30g) of nuts at least five times a week reduce their risk of heart disease by 30–50%.2–5 Nuts rich in monounsaturated fats include macadamias, hazelnuts, cashews, almonds, pistachios and pecans. While walnuts, pine nuts and Brazil nuts are rich in polyunsaturated fats. All nuts contribute fiber to the diet, containing about 8g per 100g on average. Dietary fiber can help manage cholesterol and is essential for a healthy bowel function.[iv]

Cardiovascular diseases, Cancer And Bile Acid Binding

In vitro bile acid binding can be used as tool to evaluate cholesterol lowering and cancer risk reduction ability of food. Bile acid are end product of cholesterol metabolism, synthesized in liver and required for fat absorption in gastrointestinal tract. Absorbed fat metabolism leads to cholesterol production in body. Bile acid binding of food prevents their reabsorption and stimulates blood and liver cholesterol conversion into bile acid. Secondary bile acids increase the risk of colorectal cancer. Excretion of bile acid is the major route cholesterol removal from the body. Bile acid binding values determined relative to Cholestrymine ( Bile acid binding, cholesterol lowering drug) binding is a cost effective method for screening foods and food fractions to evaluate their health promoting potential.

Studies suggest that cooked whole grain hard, red winter and hard white winter wheat have significantly higher health promoting potential than their cooked pearled grain counter-parts. It shows red colour associated with whole grain may not necessarily indicate high health benefits.  

Rice and wheat brans have significantly higher Bile acid binding capability than corn and oat bran.Wheat fiber and bran binds bile acid, provides bulk in feces hence prevent colon cancer. Studies show milling improves Bile acid binding. It could be concluded that finer particle size whole grain flour have higher health beneficial effects.

It's been found that process technologies (extruding, shredding, toasting and flaking) and fortification could be used to enhance bile acid binding capability of ready to eat cereals.

"Whole grains and cereals made from whole grains and bran (rice, oat and barley) and legumes, when consumed regularly, can help lower the risk of cardiovascular diseases and certain cancers and improve public health."

Fat Phobia

Most of the people think fat should not be a part of their healthy life. To avoid fat people use fat-free products which usually have loads of refined carbs and sugars to maintain acceptable taste profile. Ultimately such diet leads to obesity.

The truth is human body do need certain amount of fat to maintain regular body functions. Fat is the structural component of the cell, body needs it for cell repairing. Too low fat diet disturbs the absorption of fat soluble vitamins and antioxidants. Cutting fat too much can lead to constant hunger. Dr. Cate has efficiently summarized reasons to eat fat in the following pictorial illustration. 

Fat servers many physical, chemical and nutritional functions in the food. Fat improves the flavor, provides creamy texture and glossy look to the food.

Few sources of good fats.

One shouldn't avoid fat completely but monitor the quality and quantity of fat. Prefer unsaturated fat and high density lippoproteins (HDL). Polyunsaturated fatty acids (PUFA) keep heart healthy, they reduce serum cholesterol level. Take fats which are liquid at body temperature. Avoid shortenings and hydrogenated fat. By the process of hydrogenation liquid fat is converted into solid fat at room temperature, during this process there are chances of formation of trans fatty acids.

Are you still fat phobic?

Sweet Potatoes Are Really Sweet

 November is sweet potato awareness month, best time to incorporate these nutritious vegetable in your plate. 
Sweet potatoes are starchy tubers packed with vitamins, minerals and antioxidants. It is a good source of fiber, beta carotene (precursor of vitamin A), Vitamin C, magnesium and potassium. Sweet potatoes are low in sodium, fat free and cholesterol free.This nutritious vegetable has low glycemic index. They appear to stabilize blood sugar level.

Have a look at informative chart I found from Whole foods website.

Select sound and firm roots without bruises, wrinkles and decay. Choose deep orange color sweet potato for more food value.

Before cooking sweet potatoes, scrub skin and trim off any bruised or woody portions. 

Store them at cool and dry place but do NOT refrigerate. Refrigeration develops a hard core and undesirable taste after cooking.

Sweet potatoes can be baked, boiled, fried, broiled, canned or frozen. They can also be cooked in the microwave oven.
