The British Heart Foundation (BHF) is an organization that provides information and support for healthy living, including healthy eating habits. The BHF diet, also known as the "Greenlane" or "Sacred Heart" diet, is a strict diet that claims to help people lose up to 4.5kg (10lb) over three days. However, it is important to note that this diet is not recommended by the BHF and there is no scientific evidence to support its effectiveness or safety.
Positive aspects of a heart-healthy diet, according to the Better Health Channel, include:
- Legumes, nuts, and seeds: These are good sources of plant proteins, fiber, healthy fats, and micronutrients that can help lower cardiovascular risk.
- Fruits and vegetables: These offer protection against heart disease due to their fiber, potassium, and other micronutrients (such as antioxidants). They are also an important source of folate, which helps lower the blood levels of the amino acid homocysteine, which appears to be linked to an increased risk of heart disease.
Negative aspects of a heart-healthy diet, according to the Better Health Channel, include:
- Saturated fats: These tend to increase LDL (‘bad’) cholesterol in the blood. Common sources of saturated fats include animal products (butter, coconut oil, meat fat including lard and dripping, beef, lamb, chicken skin, and palm oil), and processed foods like pastries and biscuits.
- Full-fat dairy: Although full-fat dairy foods (such as milk, cheese, and yogurt) contain saturated fat, it appears this type of fat has a neutral relationship with heart health.
It is important to note that the BHF does not endorse any specific diet or product, and instead recommends a balanced and varied diet that includes plenty of fruits and vegetables, whole grains, lean proteins, and healthy fats.
