We have come across many different kinds of diets, whether it is the Hashimoto's Diet or the Harvard Diet, each offers a different kind, along with addressing different needs. Today, on our plate, we have the Portfolio Diet, created by Dr David JA Jenkins, a British physician who is also credited for developing the concept of glycemic index (GI).Studies say that this diet can lower your cholesterol levels and also promote a healthy heart. How? It adds certain cholesterol-lowering foods to your diet. The diet comprises 4 key ingredients:Soy proteinPlant sterolsTree nutsSoluble fiberExperts point out that eating more such foods can lower your cholesterol levels and protect you against any heart disease.So how does it work?The concept of Portfolio Diet is pretty simple. It requires you to simply replace certain foods in your diet with other ingredients which have lower cholesterol levels.For instance, you can replace your meat and dairy with soy protein like tofu, tempeh, soy milk, and soy-based deli meats, or burgers.Portfolio Diet encourages you to use margarine enriched plant sterols, which can become a great substitute for butter. These are naturally occurring plant compounds and can reduce your body's absorption of cholesterol. Furthermore, the diet also promoted foods high in soluble fiber. This is because soluble fiber absorbs water and forms a thick, gel-like substance in your digestive tract, which can improve digestion, lower cholesterol levels, and also reduce blood sugar spikes.So, what includes in soluble fiber?You can opt for fruits, vegetables, legumes, and flaxseeds.
