Lifestyle Medicine Update (August 30, 2019)


In the pursuit of healthier living, we often encounter warnings about reducing the intake of trans-fats, deep-fried foods, and excessive refined sugar. While these concerns are valid and well-founded, the discussion around another dietary villain tends to slip under the radar: saturated fats. A comprehensive review published on August 1st, 2019, by the UK’s Scientific Advisory Committee on Nutrition (SACN) in collaboration with Public Health England shed light on the undeniable connection between saturated fats and health. This article dives into the core findings of the SACN report, highlighting the impact of saturated fats on cholesterol levels, heart health, and overall wellbeing.

The SACN Report: Unveiling the Truth

The SACN report was a landmark effort that consolidated insights from 47 systematic reviews and meta-analyses to unravel the intricate relationship between saturated fats and human health. The culmination of this rigorous analysis led the Advisory Committee to reach several crucial conclusions:

  1. Higher consumption of saturated fats is directly linked to elevated blood cholesterol levels.
  2. Increased intake of saturated fats escalates the risk of heart disease.
  3. A prudent dietary choice involves substituting saturated fats with healthier unsaturated fats.
  4. The current advice, advocating for saturated fat consumption not exceeding 10% of daily food energy, remains valid.

The significance of these findings lies in their potential to reshape dietary habits, potentially curbing the prevalence of heart disease and its associated complications.

The Pathway to Heart Health: Understanding Saturated Fats

When you indulge in saturated fats, an intricate biochemical journey unfolds within your body. These fats traverse from the gut to the liver, where they stimulate cholesterol production. This cholesterol is indispensable for transporting saturated fats through the bloodstream, where they are either utilized as an energy source by muscles or stored as fat in adipose tissue. However, this process comes with its own set of complications.

Saturated fats trigger a surge in blood cholesterol levels, exceeding the limits conducive to optimal health. The surplus cholesterol eventually accumulates as plaque within arteries, initiating a gradual narrowing process that can culminate in blockages, heart attacks, ischemic strokes, and other vascular issues. Furthermore, excessive saturated fat intake renders blood stickier, elevating the risk of dangerous blood clots, which can trigger heart attacks, strokes, or potentially fatal deep vein thrombosis. Additionally, saturated fats promote inflammation by activating specific receptors on immune cells, contributing to the development of artery wall inflammation and escalating heart attack risk.

The Culprits: Foods High in Saturated Fats

A major challenge lies in the ubiquity of foods rich in saturated fats. The SACN report has highlighted some prominent offenders that individuals should be cautious about including in their diet:

  1.  Cakes, except for Angel Food Cake, with a particular emphasis on frosting.
  2. Pastries such as donuts, cream puffs, and chocolate eclairs.
  3. Certain muffins, often containing more than 2 grams of saturated fat.
  4. Biscuits, a common accompaniment to meals.
  5. Pancakes and French toast, depending on preparation methods.
  6. Animal products including beef, pork, and lamb.
  7. Dairy items like butter, cream, ice cream, and high-fat cheese.
  8. Oils like palm oil and coconut oil, along with shortening.
  9. Chicken legs, with skinless chicken breast being a healthier alternative.
  10. Some breakfast cereals, potato chips, and prepackaged popcorn.

Setting the Bar: Ideal Cholesterol Levels

The pursuit of heart health involves striving for specific cholesterol benchmarks. According to the SACN report, the optimal total blood cholesterol level should be at or below 3.9 mmol/L (150 mg/dl), with LDL-cholesterol (often referred to as “bad cholesterol”) maintained at or below 1.5 mmol/L (58 mg/dl). Monitoring your cholesterol levels by undergoing a blood test after a 12-hour fast can offer valuable insights into your heart disease risk.

Conclusion: Making Informed Choices for Heart Health

The SACN report underscores the undeniable impact of saturated fats on heart health and overall wellbeing. It serves as a clarion call for individuals to make informed dietary choices, emphasizing the reduction of saturated fat intake. While discussions around trans-fats and refined sugar are vital, the conversation around saturated fats should not be neglected. Armed with the knowledge of how these fats influence cholesterol levels, inflammation, and clot formation, individuals can proactively modify their diet to mitigate the risks of heart disease and related complications.
