What Are Omega-3 Fatty Acids?

Omega-3 fatty acids are a crucial type of polyunsaturated fat that play a vital role in maintaining overall health. These essential fats consist of long carbon chains, with three main types being the focus of scientific research:  

1. Alpha-linolenic acid (ALA) – Found primarily in plant-based foods  

2. Eicosapentaenoic acid (EPA) – Mostly found in marine sources  

3. Docosahexaenoic acid (DHA) – Critical for brain and eye health  

ALA is considered an essential fatty acid because the body cannot produce it. Hence, it must be obtained through diet. 

While the liver can convert small amounts of ALA into EPA and DHA, this process is inefficient. Therefore, consuming EPA and DHA directly from food or supplements is the best way to ensure adequate intake.  

Best Food Sources of Omega-3s

- Plant-based sources (ALA): Flaxseeds, chia seeds, walnuts, soybeans, and canola oil  

- Marine sources (EPA & DHA): Fatty fish (salmon, mackerel, sardines), fish oil, krill oil, and algae-based supplements  

Interestingly, fish do not produce omega-3s themselves—they accumulate them by consuming micro algae.

This is why algae oil is an excellent vegan alternative for DHA and EPA.  

Why Are Omega-3 Fatty Acids Important for Health?

1. Supports Heart Health

Studies show that omega-3s help reduce triglycerides, lower blood pressure, and decrease the risk of heart disease. Populations with high fish consumption, such as the Japanese and Greenland Inuit, have notably lower rates of cardiovascular issues.  

2. Boosts Brain Function and Development 

DHA is a major structural component of the brain and retina. Adequate omega-3 intake during pregnancy and early childhood supports healthy brain development, while in adults, it may help prevent cognitive decline, Alzheimer’s disease, and dementia.  

3. Reduces Inflammation and Autoimmune Disorders

Omega-3s have powerful anti-inflammatory effects, making them beneficial for conditions like rheumatoid arthritis, lupus, and inflammatory bowel disease (IBD). Early-life omega-3 intake may also reduce the risk of autoimmune diseases like type 1 diabetes.  

4. Promotes Mental Well-being

Research links higher omega-3 consumption to lower rates of depression and anxiety. Supplementation has been shown to improve symptoms in individuals with mood disorders.  

5. Enhances Eye Health

DHA is essential for retinal function, helping prevent age-related macular degeneration and dry eye syndrome.  

6. May Lower Cancer Risk

Some studies suggest that omega-3s may reduce the risk of breast, prostate, and colorectal cancers by inhibiting inflammation and abnormal cell growth.  

7. Supports Skin Health

Omega-3s help maintain skin hydration, reduce acne, and protect against premature aging by strengthening cell membranes.  

8. May Improve Asthma Symptoms

A diet rich in omega-3s may reduce inflammation in the airways, potentially benefiting those with asthma.

Should You Take Omega-3 Supplements?

While whole-food sources are ideal, supplements like fish oil, krill oil, or algae oil can help those who don’t consume enough omega-3-rich foods. 

However, consult a doctor before starting supplements, especially if you:  

- Take blood thinners (omega-3s can increase bleeding risk)  

- Have a seafood allergy (opt for algae-based DHA instead)  

- Experience digestive discomfort (enteric-coated capsules may help)  

Final Thoughts: Prioritise Omega-3s for Optimal Health

Incorporating omega-3 fatty acids into your balanced diet is one of the best ways to support heart health, brain function, and overall well-being. 

Aim for at least two servings of fatty fish per week or consider high-quality supplements if needed.  

By making omega-3s a regular part of your nutrition plan, you can enjoy their wide-ranging benefits—from sharper cognition to healthier skin and a stronger heart.  

Good luck 🥰

What Are Antioxidants and Why Are They Important? 

Antioxidants are powerful compounds that play a crucial role in maintaining optimal health. 

When our bodies metabolise oxygen, they produce unstable molecules called free radicals, which can damage cells, DNA, and proteins through oxidative stress. Over time, excessive oxidative stress can lead to chronic diseases like heart disease, liver disorders, cancer, and accelerated aging.

Fortunately, antioxidants neutralise these harmful free radicals, protecting our cells and promoting overall well-being. 

They are found in various nutrient-rich foods, including vitamins (A, C, E), minerals (zinc, copper, manganese), and plant-based compounds like flavonoids and carotenoids.  

Best Antioxidant-Rich Foods for a Healthier Life

A diet rich in antioxidant foods can help combat oxidative stress and enhance immunity. Here are the top sources:  

1. Fruits & Berries

- Blueberries, strawberries, blackberries (high in flavonoids & vitamin C)  

- Oranges, kiwifruit, mangoes (rich in vitamin C)  

- Watermelon, tomatoes (excellent sources of lycopene)  

2. Vegetables & Leafy Greens

- Spinach, kale, collard greens (packed with lutein & beta-carotene)  

- Broccoli, cauliflower, cabbage (contain indoles & vitamin C)  

- Carrots, sweet potatoes (high in beta-carotene & vitamin A)  

3. Nuts, Seeds & Whole Grains

- Almonds, walnuts, sunflower seeds (rich in vitamin E & healthy fats)  

- Sesame seeds, flaxseeds (great sources of lignans)  

- Oats, brown rice, whole wheat (provide manganese & fiber)  

4. Beverages & Other Sources

- Green tea, black tea (loaded with catechins & flavonoids)  

- Red wine (in moderation) (contains resveratrol & antioxidants)  

- Dark chocolate (70%+ cocoa) (high in flavonoids)  

How to Get the Most Antioxidants from Your Diet?

While supplements are available, whole foods are the best way to absorb antioxidants naturally. 

Some key tips:  

- Eat a colourful variety of fruits and vegetables daily.  

- Combine foods wisely—vitamin C enhances iron absorption, while too much zinc can reduce copper levels.  

- Avoid overcooking vegetables to preserve their antioxidant content.  

How Scientists Measure Antioxidant Levels (FRAP Test)?

The FRAP (Ferric Reducing Ability of Plasma) test evaluates how effectively food neutralises free radicals. Foods with higher FRAP values have more antioxidants. 

Some top performers include:  

- Blueberries, strawberries, raspberries

- Dark leafy greens (spinach, kale)

- Nuts and seeds

Final Thoughts: Antioxidants for Longevity & Vitality  

Including antioxidant-rich foods in your balanced diet is one of the best ways to fight inflammation, boost immunity, and slow aging. Instead of relying on supplements, focus on whole, natural sources for maximum benefits.  

Start today! Add more berries, leafy greens, nuts, and dark chocolate to your meals for a healthier, more vibrant life.  

Good luck 🥰

Best Treatment for Wound Dehiscence and How to Prevent it?

Best treatment for wound dehiscence and how to prevent it? Photo by Alexander Grey:

Best treatment of wound dehiscence is a topic of great interest as wound dehiscence is one of the main complications that people face after a surgery. 

Depending on the site of the surgery and the severity, treatment of wound dehiscence differs but the distress people undergo remains almost the same.

 

What is Wound Dehiscence?

 

Wound dehiscence occurs as a complication when you receive sutures from a surgery. The wound edges may reopen partially or fully due to the defects in the wound healing mechanism making a new wound. 

Ultimate result is that wound will take a lot of time to heal causing you unnecessary trouble.

Usually, you will notice this within one week after surgery as during this time, the wound healing process is still in early stages.

There are two main aspects of wound dehiscence. 

Superficial wound dehiscence is when the most superficial layers of wound edges are separated whereas Full thickness dehiscence is when the underlying deep layers are also involved and separated completely.

In full thickness dehiscence, if the wound is situated on a cavity as in the abdomen, this can open a pathway from the inside of the cavity to the outside as well. If so, there is a risk of internal organs coming out of this pathway. This is Evisceration. 

Evisceration is a very dangerous consequence of wound dehiscence that needs urgent proper treatment.

Tensile Strength

During the first few days of the skin wound, the tensile strength of the wound is minimal. But as the collagen tissue forms, the wound tissue will increase its tensile strength over time. 

Thus, wound dehiscence is more likely during the first few days of the wound.

  

Causes and Risk Factors of Wound Dehiscence

 

Causes and Risk factors related to the Patient

Age

Increasing age is a risk factor for wound dehiscence.

 

Malnutrition

If you have any nutritional deficiency like anemia, hypoalbuminemia, vitamin deficiencies etc. it will result in poor wound healing that will in turn can cause wound dehiscence. Most importantly, vitamin c deficiency, zinc deficiency, protein deficiency can reduce wound healing.
