Top 10 super-foods to get your omega 3

Many of us are aware that omega 3 fats are very good for maintaining health, in all age groups. They help reduce the risk of heart problems, hypertension, asthma and hypertriglyceridemia. Elderly people also benefit from consuming omega 3 fats. They help to reduce the risk of rheumatoid arthritis, and may also help in depression and Alzheimer’s disease. They are very important in development of brain of a child; hence they should be taken in pregnancy. They help to improve concentration in children.
 
But the problem is, how to ensure its intake through diet. So let’s see some of the good sources of omega 3 fats whose inclusion can help you to be in good health. Non-vegetarian sources provide you eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), whereas vegetarian sources are rich in alpha linolenic acid (ALA).

2.      Omega-3-enriched eggs: Omega-3-enriched eggs are obtained by feeding flaxseed or algal DHA to poultry. Normally 2-3 eggs are required to satisfy 0.1g of omega 3 fatty acids. One flaxseed-enriched egg[1] fulfills the same quantity, whereas you require only ⅔ of a DHA-enriched egg for the same.

3.      Chia seeds: Also popularly known as subja, it is a very good source of omega 3 fatty acids. One tbsp (15g) of subja seeds provide you around 5g of ALA. Subja is most commonly used in milkshakes and faludas. The best way is to have 1 tbsp of subja seeds along with milk every morning. It also provides soluble fiber, which is good for relieving constipation.

4.      Flaxseeds: Also known as ‘alsi’, it is a rich source of ALA. It is recommended to have 2 tbsp (30g) of ground flaxseed powder daily for its benefits. Flaxseeds also contain soluble fiber that promotes flaxseeds’ cardio-protective effects. Flaxseed oil, extracted from the seeds, is one of the richest sources of ALA. It contains around 55% ALA. Flaxseed powder can be used in chutneys or mixed with atta. It can also be used as salad oil.

5.      Perilla seeds: Perilla is known as ‘bhanjira’ or ‘silam’ in Hindi. It is roasted and used in chutneys. It is another good source of omega 3 fatty acids. Perilla oil contains 64% ALA.

6.      Canola oil: It is most commonly used as cooking oil. It is low in saturated fat, high in monounsaturated fat and contains around 11% omega 3 fatty acids. The ratio of omega 3 to omega 6 fatty acids is good (2:1) in canola oil.

Omega 3 fats: The heart health boosters

Heart diseases are no longer a concern only for people who have crossed 40s or 50s. In past few decades, age of getting heart attack in India has plunged to 30 years. The situation is really alarming and we need to take preventive steps before it’s too late. One of the steps can be inclusion of omega 3 fats in the diet, which will protect our heart and arteries from various problems.

What are omega 3 fatty acids?

This is a family of good fats that offer a number of advantages. There are three members in the family, namely alpha linolenic acid (ALA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). These are essential fats, which are not formed in the body, hence should be included in the diet. ALA acts as raw material for formation of EPA and DHA; however this conversion is not so efficient. Hence, if possible, it is always preferable to get EPA and DHA directly from food. There is another family of essential fats, called as omega six fatty acids which are also required for various body functions. But if taken in excessive amounts, they can have harmful effects.


Why is omega 3 important?
A number of researches have shown that the consumption of omega 3 reduces the risk of deaths from the heart diseases. There are a number of ways in which EPA and DHA help to protect your heart.
1.      Reduce irregular heartbeats (arrhythmia):
Arrhythmia is a problem with rhythm of the heart. Heart beat can be too fast or too slow, or it may have irregular rhythm. Because of this irregularity, the heart cannot pump the blood efficiently and the organs such heart or brain may get damaged.

2.      Decrease thickening of arteries:
Arteries are like flexi-pipes, which carry nutrients and oxygen-rich blood to the body. As we become older, arteries lose their flexibility and do not transport the blood efficiently. This may block or reduce the blood flow to the heart and other parts of the body, leading to a heart attack or a stroke.
EPA and DHA reduce a number of risk factors, such as blood pressure, high triglycerides levels, and inflammation that contributes to the process of hardening of arteries.

3.      Reduce the risk of hypertriglyceridemia:
Increased levels of triglycerides in the blood can lead to arthrosclerosis. EPA and DHA help to reduce the triglycerides in the blood.

4.      Reduces blood pressure:
High blood pressure is a risk factor for heart attack, heart failure, stroke and other cardiovascular diseases. EPA and DHA help to reduce the blood pressure in the hypertensive people, reducing the risk of heart diseases.

Both EPA and DHA are necessary for a healthy heart. Unfortunately, they are present only in the non-vegetarian sources, such as fish and fish oil supplements. Thus, it is recommended that people who are not suffering from any heart disease should consume 500mg of EPA and DHA per day. This amount generally gets fulfilled by consuming fish, especially oily fish, twice a week.
People who are suffering from coronary heart diseases should consume 1g of EPA+DHA daily.
Those, with very high levels of triglycerides in the blood, should consume 3g to 4g of EPA+DHA daily.
Vegetarian sources do not contain EPA and DHA; they are good for ALA. ALA is starting material for our body to form EPA and DHA. However, the conversion in it is not so efficient. Though there is no unanimous recommendation for ALA, generally, 1 to 3 g of ALA help to maintain good health.
How to get omega 3 fatty acids in your diet?
Fish, especially oily fishes, are an excellent natural source of omega 3 fatty acids. It is recommended to consume fish twice a week to fulfill the EPA and DHA requirements. Among vegetarian sources, you can have flaxseed oil, canola oil or mustard oil in your daily diet. Flaxseeds and walnuts are also good sources of omega 3 fatty acids.

No time for sunshine!


It's a human nature to make simple things complicated; rather we cannot live unless we make things complicated. The simplest act of exposing yourself to sunlight can prevent severe weakening of bones or old age fractures. But unfortunately we are so busy behind our office doors and in the closed cars, that there is no time for sunshine!
It's unfortunate and shocking to know that 80% to 90% of Indian metro city population is deficient in vitamin D.

What will happen if you are deficient in vitamin D?


 


1)      It increases the muscle weakness and subsequently the risk of fractures. It decreases the size and strength of bone, and also leads to osteomalacia (softening of bones)

2)     Low serum vitamin D levels may also increase the risk of cardiovascular diseases, type I diabetes, certain forms of cancers, multiple sclerosis and rheumatoid arthritis.

How to detect?

There are no peculiar signs or symptoms for vitamin D deficiency. Generally it gets detected when you go to the physician with persistent muscular pain, back pain or fractures.

It’s important to get your vitamin D status checked on time! Those who fall in to any one of the following groups should get their serum vitamin D level checked.

1.      If you are suffering from persistent muscular pain.

2.     Your lifestyle is very hectic, particularly desk jobs with minimal exposure to sunlight.

3.      If you are a heavy sunscreen applier.

4.     If you use burkha, or wear clothes that leave minimal chance of exposure of skin to sunlight.

5.      You are living in highly polluted city. Pollution can obstruct UV rays from forming vitamin D in the body.


What is recommended amount?

India is a sunny country; it was never thought that vitamin D deficiency would have been very prevalent. More than 80 studies were reviewed and it was concluded that food cannot be a substitute for adequate sunlight. Average Indian diets provide roughly 10% of the total vitamin D requirements. So, there is no recommended intake of vitamin D for Indians. 400 IU (10µg) of daily supplement is recommended if someone is completely devoid of sunlight.

What should be the prevention plan?

1)     Get enough sunlight: The cheapest and easiest solution is to expose you to sunlight. As per FAO/WHO Expert Consultation, half an hour exposure to sunlight every day can prevent vitamin D deficiency.

2)     Eat right food: Though foods are not very good sources for vitamin D some of the sources are dairy products such as cheese, cream, butter, fatty fishes, and egg yolk.

3)     Vitamin D fortified products: Unlike US, vitamin D fortification is not very common in India; though some oils, imported breakfast cereals do contain some level of vitamin D.

4)     Nutritional supplements: There are many vitamin D supplements available in market including fish oil and cod liver oil pills. Vitamin D supplements are also available in powder form, e.g. D rise. However, these supplements should be used under the guidance of a nutritionist or a doctor. Being a fat soluble vitamin, vitamin D easily gets stored in the body. Overdose of these supplements can lead to vitamin D toxicity, which can have serious implications such as kidney damage, calcification of heart and lungs, confusion and disorientation etc.

Hence, the best prevention strategy is to play outdoors in sunlight. Even a morning brisk walk or a stroll in the office compound after lunch will help to reduce the risk.

So, the key is to take some time out for sunshine!!!

Oats : The heart grain


Oat is a wonderful whole grain cereal to have in your regular diet. There are various ways by which oats can be relished such as oatmeal, oat porridge, Instant oats, flavored oats, oat cookies, oat bars and so on… It has been scientifically proven that oats help to improve heart health through various mechanisms.

1.       Reduce the risk of heart disease: Oats, a whole grain cereal has a number of advantages. Research has shown that high levels of whole-grain consumption i.e. 3 or more servings per day are associated with reductions in risk for cardiovascular disease. Also,there are certain unique phenolic compounds  in oats called as avenanthramide which has shown to reducing early atherogenic events.

2.       Cholesterol Reduction:  Oats contain a unique soluble fiber beta glucan which helps to reduce bad cholesterol i.e LDL cholesterol from your body. LDL cholesterol is major risk factor for cardiovascular disease. USFDA has approved a health claim on oats saying  that 3 grams of beta glucan from oats daily along with a diet low in saturated fat may help you to reduce the risk of coronary heart disease

3.       Reduce the risk of diabetes: Diabetes is an independent risk factor for heart disease. Epidemiologic studies have shown an inverse relationship between wholegrain consumption and the risk of developing type 2 diabetes. Oats is very good source of soluble fiber. Soluble fiber such as beta glucan helps to maintain steady glucose levels.
 
4.       Helps to decrease weight: Obesity is another cause for developing cardiovascular disease. Research has shown that 5-30 g of soluble or insoluble fiber daily can effectively reduce food intake and/or hunger and produce weight losses that last for up to 52 weeks.
 
5.       May aid in lowering blood pressure: High blood pressure increases the pressure on blood vessels of the heart which may lead to injury and increases the risk of coronary heart diseases. Observational studies indicate that population consuming whole grain cereals such as oats have lower blood pressure. A study conducted in China demonstrated that people consuming 25 g oats daily had lower systolic and diastolic blood pressure.
